Investigation of high school students' motivation for physical activity participation and eating attitude levels during the COVID-19 period

The aim of this study is to determine the motivation of high school students to participate in physical activity and their eating attitude levels during the COVID-19 period as well as to examine the relationship between the two variables. In addition, it was also determined whether the motivation for participate in physical activity and eating attitudes differ according to gender, weekly exercise, spending time with technology, family communication times, and participation in exercise during and before the pandemic. A total of 576 high school students, including 406 girls and 170 boys, participated in the study. "Motivation Scale for Participation in Physical Activity (MSPPA)", "Eating Attitude Test (EAT-40)" and "Personal Information Form (KBF)" were used as data collection tools. Data were evaluated using correlation, multiple linear regression, MANOVA and t-test analysis techniques. It was concluded that the motivation of the students to participate in physical activity was moderate, and they did not have eating disorders. It was observed that physical activity motivation did not predict eating attitude, but there were positive and low relationships between sub-factors in relational dimension. According to gender, it was determined that the eating attitudes of female students were more positive than male students. It has been found that the motivation to participate in physical activity is higher for those who exercise before and during the pandemic than those who do not. Consequently, it can be said that during the COVID-19 process, high school students' motivation to participate in physical activity is at a moderate level, and their eating attitudes are generally not at the level of behavioral disorders.

Comparing the effects of endurance and resistance training programs on some pulmonary, functional, and quality of life indicators in patients with COVID-19 discharged from hospital

Background and purpose: The present study investigated the effect of six weeks of endurance and resistance training on pulmonary indices, physical performance, and quality of life in COVID-19 patients after discharge from hospital. Materials and methods: Thirty six patients with COVID-19 (mean age: 38.76+or-0.98 years, mean weight: 81.86+or-2.88 kg) were selected. At the beginning and end of the study, pulmonary (FEV1, FVC, FEV1/FVC, and MVV), physical (6-minute walk test), quality of life (SF-36), and anthropometry tests were performed. The patients were divided into three groups: Endurance training (45 minutes at 60-75% estimated HR), Resistance training (45 minutes at 40-70% of I-RM), and controls. The intervention was conducted for 6 weeks (3 sessions). One-way ANOVA test was used for statistical analysis. Results: Findings indicated a significant increase in FEV1 (P=0.029), FVC (P=0.047), FEV1/FVC (P=0.043) in the endurance training group compared to the control group, while difference was observed in MVV (P=0.041) and FEV1/FVC (P=0.022) between endurance training and resistance training groups. The 6-minute test distance increased in the endurance training (P=0.0001) and resistance training (P=0.001) groups compared to the control group, but no difference was observed between the training groups (P=0.48). Endurance and resistance training programs induced significant improvements in physical performance (P=0.024 and P=0.09, respectively) and general health (P=0.022 and P=0.015, respectively) dimensions compared to the control group. Conclusion: Moderate-intensity endurance training can improve pulmonary function, physical performance, and quality of life in patients with COVID-19 after discharge from hospital and can be used in rehabilitation programs of these patients.

Emerging technology as an essential factor in changing lifestyles and reshaping exercise behaviour in Taiwan. (Special issue on 2023 Asia Pacific sport and social science.)

The COVID-19 pandemic has influenced various aspects of people's lives;for instance, restrictions during the pandemic have forced people to think about sports participation and physical activity in new ways. There has been growing interest in technological interventions to support exercise-related behavioural changes in daily life;in particular, exergames designed to induce full-body movement offer alternatives to physical activity. Since Taiwan has a high rate of ownership of exergame-related equipment, it is worth examining players' perceptions of using exergames for exercise. This study utilised a Means-End Chain analysis with in-depth laddering interviews to investigate Taiwanese perceptions of certain attributes of exergames as most likely to produce desired consequences in accordance with their values. The findings provide researchers and practitioners interested in the use of technology for exercise with valuable implications of Means-End Chain theory and structuration theory and suggestions for exergame design and promotion.

What is being uploaded on YouTube?: Analysis of fitness-related TouTube video titles pre- and post-COVID-19 in Korea. (Special issue on 2023 Asia Pacific sport and social science.)

Opportunities to participate in physical activities (PA) and fitness exercises in public and private facilities have been reduced or banned due to social distancing regulations during the height of the global pandemic. Though Korea has not experienced lockdown, several venues have been restricted to prevent the spread of Covid-19. Despite the limitations of PA engagement, people have found alternative activities by using online platforms to keep active and fit. Thus, this study focuses on analyzing fitness-related video titles from YouTube. By collecting data through text mining and conducting network analysis, it provides basic knowledge of the fitness trends from pre- and post-Covid-19. As a result, 'exercise' was found to have the highest tendency and had strong connections to keywords that indicated specific methods of working out to become fit, but it also had connections to trendy keywords such as 'hip-up' and 'body-profile' which reflect the fitness culture in Korea.

Effects of training and protein/carbohydrate supplementation by food on strength, body composition and bone metabolism in postmenopausal women

Background: Menopause is associated with impairments of health, e.g. cardiovascular disease, changes in body composition, decrease in bone density. Physical activity and nutrition strategies have been demonstrated to counteract some of these disabilities. Aim of the present study was to analyze the impact of 3 months of strength and endurance training combined with protein/carbohydrate supplementation on strength, body composition and bone metabolism in postmenopausal women. Method(s): 62 postmenopausal women were recruited. Measurements: Body composition by BIA. Strength of leg, chest and handgrip. delta44Ca/42Ca in blood and urine as proxies for bone metabolism, samples were analyzed by mass spectrometry. Participants completed 2/week endurance training (walking) for 60 minutes (60-75% km/h of 4mmol threshold) and a whole-body strength training 1/week for 60 minutes (online). In addition, the intervention group (IG) received 100g of sour milk cheese and 76g of white bread (35.3 g carbohydrate, 36.1 g protein, 3.5 g fat, 321 kcal) after each training. Result(s): Training results in an anabolic effect on bone metabolism, here protein/carbohydrate supplementation does not show additive effects. Training resulted in an increase of leg and hand grip strength. For hand grip strength an additive effect could be demonstrated after protein/carbohydrate supplementation. Both groups increased muscle mass and reduced fat mass, although the results were not significant. Discussion(s): Training was effective, showing an increase in strength. Additive effects of the nutritional intervention could be only observed for hand grip strength. This may be due to a weak compliance of the protein/carbohydrate supplementation by a meal while corona pandemic. Also, because of the endurance parts, the training was not specifically designed to increase strength. Nevertheless, even this mild training has a remarkably strong impact on bone metabolism. Conclusion(s): Even if the effects are faint, the data of this study provide evidence that protein/carbohydrate supplementation, also by food, supports the events of training on strength. Training has a strong impact on bone metabolism in postmenopausal women. The subjects respond very individually to training and nutrition interventions. Training consequentially is to be personalized.Copyright © 2023

Impact of (long) COVID on athletes' performance: a prospective study in elite football players.

OBJECTIVES: To investigate possible persistent performance deficits after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in elite athletes. METHODS: A prospective cohort study in three Belgian professional male football teams was performed during the 2020 - 2021 season. Participants were submitted to strength, jump, and sprint tests and an aerobic performance test (the Yo-Yo Intermittent Recovery test (YYIR)). These tests were repeated at fixed time intervals throughout the season. Assessment of SARS-CoV-2 infection was performed by a polymerase chain reaction (PCR) test before each official game. RESULTS: Of the 84 included participants, 22 were infected with SARS-CoV-2 during follow-up. At the first testing after infection (52.0 ± 11.2 days after positive PCR testing) significantly higher percentages of maximal heart rate (%HRmax) were seen - within the isolated group of infected players- during (p = .006) and after the YYIR (2 min after, p = .013), compared to pre-infection data. This increase in %HRmax was resolved at the second YYIR testing after infection (127.6 ± 33.1 days after positive PCR testing). Additionally, when comparing the first test after infection in formerly infected to non-infected athletes, significantly higher %HRmax were found during (p < .001) and after the YYIR test (p < .001),No significant deficits were found for the jump, muscular strength or sprint tests.Aerobic performance seems compromised even weeks after infection. Simultaneously, anaerobic performance seemed to be spared. Because of the potential detrimental effects on the immune system, caution might be advised with high-intensity exposure until aerobic performance is restored.KEY MESSAGESElite football players' aerobic performance seems to be affected for weeks after they return to sports after a SARS-CoV-2 infection.Similarly, anaerobic performance tests showed no discernible changes between both before and after SARS-CoV-2 infections.Regular YYIR testing is recommended to monitor aerobic performance after SARS-CoV-2 infection.

Secular change in selected motor performance parameters and BMI in Swiss primary school children from 2014-2021: The Sportcheck+ study.

It is important to monitor secular trends in children's motor performance, as healthy and physically active children are more likely to become healthy and physically active adults. However, studies with regular and standardized monitoring of motor performance in childhood are scarce. Additionally, the impact of COVID-19 mitigation measures on secular trends is unknown. This study describes secular changes in balancing backwards, jumping sidewards, 20-m sprint, 20-m Shuttle Run Test (SRT) and anthropometric data in 10'953 Swiss first graders from 2014 to 2021. Multilevel mixed-effects models were used to estimate secular trends for boys vs. girls, lean vs. overweight and fit vs. unfit children. The potential influence of COVID-19 was also analysed. Balance performance decreased (2.8% per year), whereas we found improvements for jumping (1.3% per year) and BMI (-0.7% per year). 20-m SRT performance increased by 0.6% per year in unfit children. Children affected by COVID-19 measures had an increased BMI and were more overweight and obese, but motor performance was mostly higher. In our sample, secular changes in motor performance show promising tendencies from 2014 to 2021. The effects of COVID-19 mitigation measures on BMI, overweight and obesity should be monitored in additional birth cohorts and follow-up studies.

Physical fitness in Austrian elementary school children prior to and post-COVID-19.

Background: With the emergence of the COVID-19 pandemic, many countries implemented policies that included movement restrictions, social distancing and school closures in order to control the spread of the virus. Even though these actions may have been necessary to save lives, there have been some unintended consequences that could affect future public health. Methods: The present study uses data from more than 24,500 Austrian elementary school children (51.2% male) that participated in a state-wide fitness evaluation program, which was initiated in the 2016/17 school year. In addition to body weight and height, data on cardiorespiratory endurance, muscular power, speed, agility, flexibility and object control were collected from three cohorts prior to the implementation of movement restrictions (school years: 2016/17, 2017/18, 2018/19) and one cohort in 2022, after the majority of COVID-19 policies had been lifted. Results: Body mass index percentiles were significantly higher in children post-COVID-19 (p < 0.01). Further, cardiorespiratory endurance, agility and flexibility were significantly lower post-COVID-19 compared to the years preceding movement restrictions (p ≤ 0.01), while absolute muscular strength was higher in the year 2022 (p < 0.01). Conclusion: Given the detrimental effects of COVID-19 policies on physical fitness in children, additional efforts are necessary that include versatile opportunities for physical activity and the promotion of physical fitness in order to modify the observed negative health trajectories and ensure future public health.

Resiliency among Older Adults Receiving (Roar) Lung Cancer Treatment: A Feasibility Study

PURPOSE/HYPOTHESIS: Poor physical performance and negative mood are two risk factors for functional decline among older adults with lung cancer. Yet, targeted interventions to maintain independence prevent functional decline are not well studied. Our primary objective was to assess the feasibility of a novel virtual health physical therapy (PT) plus progressive muscle relaxation (PMR) intervention with longitudinal microbiome biospecimen collection delivered to older adults with advanced lung cancer. Secondary objectives were to characterize functional status and clinical factors pre and post-study intervention. NUMBER OF SUBJECTS: We accrued adults aged >=60 years with advanced non-small cell or extensive-stage small cell lung cancer receiving treatment at The Ohio State University James Comprehensive Cancer Center (OSU-JCCC) in the Thoracic Oncology department (N=22). There were no exclusion criteria pertaining to Eastern Cooperative Oncology Group (ECOG) performance status, laboratory values, prior cancer diagnoses, presence of comorbidities, or brain metastases. MATERIALS AND METHODS: Participants were asked about functional status, symptoms, mood through the PHQ-9, GAD-7, POMS, and acceptability questions about the program. PT evaluation and assessment included SPPB and 2- or 6-minute walk test outcomes. The study sought to collect gut microbiome samples for every in-person visit and activity monitoring data (Actigraph) on a subset. Feasibility was defined as successfully collecting specimens, wearing an Actigraph activity monitor, and adhering to the intervention. PT and psychologists evaluated participants in-person at the first and final visit. The rest of the 12-week intervention was conducted via virtual health. Physical therapy intervention consisted of endurance, strength, and flexibility exercises. RESULT(S): In total, 22 patients consented and 18 started the intervention (81.8%). Seven microbiome samples were collected from four participants. Six patients collected activity monitoring data. Among the 18 participants, 11 participants (61.1%) completed 70% or more of all the intervention visits. The SPPB data show a moderate effect size (Cohen's d=0.24) from pre- to post-data. On average patients improved by 1.8 total points on the SPPB. Patients demonstrated improvement on timed walk tests throughout intervention from an average of 108 feet pre-intervention to an average of 138.4 feet post intervention. CONCLUSION(S): Despite the challenges of the COVID-19 pandemic, longitudinal biospecimen and correlative data collection were feasible in the context of PT and PMR intervention among older adults with advanced lung cancer. Virtual physical therapy interventions can be safely delivered to improve physical performance as demonstrated by a moderate effect size for the SPPB in this patient population. CLINICAL RELEVANCE: Based on the feasibility study results, delivering a virtual PT intervention to older patients with lung cancer can improve SPPB score leading to decreased frailty and improve quality of life among patients.

Just Keep Swimming...Just Keep Swimming

History: We present a 15-year-old right hand dominant high school swimmer with no significant past medical history, who complains of right elbow pain along the distal biceps' tendon for a 2 months. Pain was insidious in onset, sharp, intermittent, and described as a 0 to 6 out of 10. The patient has been swimming more frequently over the last few months to prepare for competition and noticed progressive pain with swimming. He went on vacation and then was diagnosed with a COVID-19 infection and took an additional 2 weeks off due to fatigue. He returned to sport without re-integration and increased his swimming intensity to 1 to 2 hours daily, which worsened his pain. Performing the butterfly and breaststroke provoke symptoms and cessation of activity reduces the pain. Denies pain at rest. He took Advil which did not reduce his pain. Denies acute trauma, prior injuries, or paresthesias. Physical Exam: Inspection of right elbow: no swelling or signs of discoloration. Palpation: Tenderness at the distal biceps tendon but can hook the tendon without pain. No shoulder or wrist tenderness. Active Range of Motion: Elbow extension 0 degrees, elbow flexion 130 degrees, supination and pronation normal. Normal shoulder and wrist ROM. Muscle strength: 5/5 grip, wrist extension, and wrist flexion. Pain elicited with resisted elbow flexion at the distal humerus. Maneuvers: pain with distal humerus squeeze. Negative Maudsley and negative Cozen test. Differential Diagnosis: 36. Distal Biceps Tendonitis/Tear 37. Stress Reaction of the Distal Humerus 38. Medial Epicondyle Apophysitis 39. Capitellar Osteochondritis Dissecans 40. Radiocapitellar Plica Syndrome Test Results: x-ray right elbow: AP and Lateral views indicate no abnormalities to the bones, alignment, or soft tissue structures. MRI right elbow No IVCON: Biceps tendon intact. There is periosteal edema and endosteal aspect marrow edema along the medial aspect of the distal diaphysis and metaphysis of the humerus. Several small foci of increased cortical signal. No fractures, joint effusion, or chondral defects. Findings comparable to Fredrickson grade 4a distal humerus diametaphysis stress injury. Final Diagnosis: Right Elbow Supracondylar Grade 4a Stress Reaction. Discussion(s): Actives that involve repetitive motion are susceptible to overuse injuries. Cases of upper extremity stress reactions in swimmers have been documented along the inferior angle of the scapula, upper ribs, and olecranon. Stress reactions along the distal humerus in swimmers is not well documented. This pathology has been seen in baseball players, cricket bowlers, and tennis players. In swimming, the butterfly technique requires significant endurance and athletic strength. During a sprint, fast synchronized upper extremity revolutions occurring up to 60 cycles perminute counterforcewater surface area friction leading to excessive loading forces even at 50 meter distances. Outcome(s): The patient was withheld from upper body work outs and swimming for 6 weeks. VitaminDand Calcium levels were drawn revealing a normal calcium level (10.2), but a vitamin D level of 28.1. Patient was started on 600 IU of Vitamin D and 1300 mg of Calcium daily. The patient started a return to swim program and returned to full competition at 7 months post presentation. Follow-Up: At 6 weeks, started an upper extremity low impact non-aquatic physical therapy program. Then a slow progressive return to swimming was initiated at 50% effort for 4 weeks. At 10 weeks, a return to sport plan including 200 m all strokes except butterfly, progressed to 250 m at week 2, 300 m at week 3, and 350 m at week 4. Finally, initiated speed work in =0 to 100 m increments and elbow loading workouts.

Fitness Assessments of Women with Polycystic Ovary Syndrome: A Prospective Process Feasibility Study

Background: Fitness is a marker of physiological and mental health. The purpose of this pilot study was to assess the feasibility of processes to recruit women with polycystic ovary syndrome (PCOS) during the Covid pandemic and collect their health and fitness data. Additionally, the data was used to explore possible associations between anthropometrics, PCOS biomarkers, health-related quality-of-life (HRQoL), and depressive symptoms with that of fitness and self-reported physical activity levels among women with PCOS. Method(s): A convenience sample of women with PCOS (n = 15) were recruited via flyers and the snowball method. Participants completed surveys, anthropometrics, a dual energy x-ray absorptiometry scan, blood work, and a fitness assessment. Data were statistically analyzed using Spearman correlations. Result(s): Feasibility measures of recruitment and retention rates were 83% and 100%, respectively. Fidelity measurement for process averaged 97%. Participants (age 25.9 (+/- 6.2), mostly White (80%), single (60%), and employed full-time (67%)) were categorized as obese (body mass index (BMI) 32.2 kg/m2 +/- 8.3, percent bodyfat 41.1% +/- 8.1) with <=1 comorbidity. Most participants were not regularly physically active and had high free testosterone levels (7.6 pg/mL+/-4.3), elevated high-density lipoprotein (63.2 mg/dL+/-12.9), fair cardiovascular capacity, and below average muscular strength/endurance. The following statistically significant and strong associations were found: (1) VO2 max with percent bodyfat (-0.59;p = 0.02), sex hormone binding globulin (0.73;p = 0.00), HRQoL (0.72;p = 0.00), and depressive symptoms (-0.67;p = 0.00), (2) abdominal strength with BMI (-0.66;p = 0.01) and high density lipoprotein (HDL) (0.59;p = 0.02), (3) physical activity level with percent bodyfat (-0.72;p = 0.00), and (4) resistance training with low density lipoprotein (LDL) (-0.52;p = 0.05). Conclusion(s): Collecting health and fitness data from women with PCOS is a feasible research approach. Randomized controlled trials in which health and fitness data are collected from women with PCOS are needed to confirm possible associations between fitness and PCOS clinical features and is in the planning process.

The effect of a physical exercise package on the motor proficiency of students with down syndrome

Objectives: The purpose of this study was to evaluate the feasibility and potential effect of a physical exercise package on the motor proficiency of children and adolescents with Down syndrome. Methods: In this research, an experimental design was conducted in two special schools to evaluate the effectiveness of this package and identify its strengths and weaknesses. Forty students with Down syndrome were selected and randomly divided into intervention and control groups. A total of 36 (22 male and 14 female) students out of 50 at two special schools for children with special needs between October 2020 and March 2021 were recruited for the study. Participants were aged 12.888 +or- 2.375 (12.954 +or- 2.609 for boys and 12.785 +or- 2.044 for girls) years. The 18 students in the intervention group participated in the exercise sessions, 2 or 3 sessions per week for 12 weeks. Pre- and post-tests were performed on both groups. The Physical Exercise Package included the principles of exercise, the preferred exercise methods, and the details of exercise planning for Down syndrome individuals (FITT-VP) based on the etiology of Down syndrome and the characteristics of people with this syndrome. Motor proficiency was measured using the Bruininks Oseretsky Test of Motor Proficiency (BOT-2). Results: The results of the study showed that the designed exercise package was adhered to with all the participants attending 93.2% of the sessions, and participants significantly improved their total motor proficiency score, manual dexterity, upper-limb coordination, strength, balance, upper-limb coordination, running speed and agility and fine motor Integration (P < 0.05). However, the exercises did not significantly change the bilateral coordination and fine motor precision (P > 0.05). Conclusions: the current study result shows that developing and implementing the individualized exercise package and observing the principles set out in the program could have significant positive impacts on the motor proficiency of students with Down syndrome.

The Influence of Different SARS-CoV-2 Strains on Changes in Maximal Oxygen Consumption, Ventilatory Efficiency and Oxygen Pulse of Elite Athletes.

PURPOSE: The aim of this study was to evaluate the influence of different SARS-CoV-2 strains on the functional capacity of athletes. METHODS: In total, 220 athletes underwent cardiopulmonary exercise testing (CPET) after coronavirus infection and before returning to sports activities. Eighty-eight athletes were infected by the Wuhan virus, and 66 were infected during the Delta and Omicron strain periods of the pandemic. RESULTS: The CPET results showed significantly decreased maximal oxygen consumption, ventilatory efficiency, and oxygen pulse in athletes who were infected with Wuhan and Delta strains compared to athletes who suffered from Omicron virus infection. An early transition from aerobic to anaerobic metabolic pathways for energy production was observed in the Wuhan and Delta groups but not in athletes who were infected with the Omicron strain. There were no differences in the obtained results when Wuhan and Delta virus variants were compared. CONCLUSION: These results suggest that the Wuhan and Delta virus strains had a significantly greater negative impact on the functional abilities of athletes compared to the Omicron virus variant, especially in terms of aerobic capacity and cardiorespiratory function.

Mobile Gamers versus Non-gamer students' endurance levels via Beep and 3-minute step test

Background and Study Aim Material and Methods College students' activity levels are considerably affected by mobile gaming, according to multiple studies. There have, however, been no studies done to date comparing gamers and non-gamers in terms of their levels of endurance. This present study employed beep and 3-minute step tests to compare mobile gamers' and non-gamers endurance levels. In addition, the difference between demographic variables such as age, gender, and BMI and participants' aerobic capacity is a major area of study. Students at the City College of Angeles in the Philippines were selected using the Judgement Sampling Technique to take part in the research. Students who participated in the study are enrolled in the 1st Semester of the Academic year 2022-2023. A survey questionnaire consisting of four sections were utilized to obtain information from the respondents. Age, gender, body mass index (BMI), and an endurance test are all part of the personal profile. Both the beep test and the 3-minute step test were administered to the participants. Results from the participants' personal profiles, BMIs, and endurance tests were summarized using descriptive statistics like frequency (f) and percentage (%). The Paired T-Test was also used to find out if there was a significant difference in the participants' endurance between mobile gamers and non-gamers. Finally, the individuals' age, gender, and Body Mass Index (BMI) were validated with their endurance levels by performing Independent Samples T-Test and One-way ANOVA. Results Beep and 3-minute step tests showed that gamers and non-gamers have very different levels of endurance, with the latter group displaying much more stamina than the former. It was also shown that among the three factors studied, gender was the only one with a relationship to endurance. Conclusions The study did not take into account factors like health history including nutrition, diet, sleep pattern, lifestyle, health issues, and endurance level on other types of measures. Conducting an inquiry similar to the one that was done, but also taking into account the other variables indicated, is a highly suggested course. Several findings are established, and numerous suggestions for further research, as well as policy and educational applications, are provided.

The Impact of Pandemic Lockdowns and Remote Learning on Student Fitness: An Investigation of Changes to High School Student Fitness Levels

Purpose: The purpose of this study was to investigate the impact on health-related fitness resulting from COVID-19 lockdowns on male high school students in Melbourne, Australia. Method: A total of 146 students completed fitness testing in February and retesting in November following 7 months of remote learning. Fitness tests conducted were 20-m shuttle run (Beep Test), flexed arm hang, body mass index, push-ups, sit-ups, and sit and reach. Results: The mean fitness levels of this cohort decreased across the health-related fitness components. Decreases were varying in magnitude, body composition (d = 0.3), flexibility (d = 0.56), muscular strength (d = 0.64), muscular endurance (d = 0.39 and d = 0.26), and cardiovascular endurance (d = 0.96). Discussion: The impact on students' fitness levels was noteworthy, and the long-term impacts of this decrease are yet to be seen. This research brings focus to what can be done to maintain adolescent fitness when their usual exercise opportunities are not available.

A temporal examination of inspiratory muscle strength and endurance in hospitalized COVID-19 patients.

BACKGROUND: The two most common symptoms associated with COVID-19 are dyspnea and fatigue. One possible cause of such symptoms may be inspiratory muscle weakness. OBJECTIVES: The purpose of this study was to examine inspiratory muscle performance (IMP) from intensive care unit discharge (ICUD) to hospital discharge (HD) in patients with COVID-19 hypothesizing that IMP would be markedly depressed at both ICUD and HD. METHODS: IMP was examined at ICUD and HD via the PrO2 device (PrO2 Health, Smithfield, RI) which provided the maximal inspiratory pressure (MIP), sustained MIP (SMIP), inspiratory duration (ID), and fatigue index test (FIT). Patient symptoms were assessed at ICUD, HD, and 1-month post-HD. RESULTS: 30 patients (19 men, 11 women) with COVID-19 were included. The mean±SD age, BMI, and length of ICU and hospital stay was 71±11 yrs, 27.9 ± 6.3 kg/m, 9 ± 6 days, and 26±16 days, respectively. The mean±SD MIP, SMIP, ID, and FIT of the entire cohort at ICUD vs HD were 36±21 vs 40±20 cm H2O, 231±157 vs 297±182 PTU, 8.8 ± 4.2 vs 9.5 ± 4.6 s, and 9.0 ± 9.4 vs 13.1 ± 12.3, respectively, with only SMIP and FIT significantly greater at HD (p=.006 and 0.03, respectively). SMIP at HD was significantly related to resting dyspnea at HD (r=-0.40; p=.02). The SMIP and FIT of men were found to increase significantly from ICUD to HD, but no measure of IMP in the women increased significantly from ICUD to HD. At least one COVID-19-related symptom was present 1 month after HD with the most persistent symptoms being fatigue, cough, and dyspnea in 47%, 40%, and 37% of the patients, respectively. CONCLUSIONS: A significant reduction in IMP exists in patients with COVID-19 at both ICUD and HD and no measure of IMP in women was observed to increase significantly from ICUD to HD. Impaired inspiratory muscle endurance rather than strength was associated with greater dyspnea at HD.

Telerehabilitation in Response to Critical Coronavirus: A Systematic Review Based on Current Evidence.

Background: The aim of this systematic review was to evaluate and identify the latest evidence on the feasibility and accessibility of telerehabilitation services in the prevention, diagnosis, treatment and control of patients with COVID-19. Method(s): The studies were retrieved from the authoritative scientific databases Embase, Web of Science, Scopus, PubMed on November 25, 2021. Then, the gray literature was scrutinized using the Google search engine to identify the latest possible evidence. Randomized controlled trial studies and protocols that used the telerehabilitation approach as an intervention to improve the condition of distant COVID-19 patients were part of the inclusion criteria. In order to assess the quality of the studies entering this study, the Joanna Briggs Institute Critical Appraisal Checklist for Randomized Controlled Trials was used. The same checklist was used for data extraction. Finding(s): A total of 7 eligible articles were obtained in this review. The quality assessment results showed that there was no significant bias in the studies and all studies were eligible to be included in our study. In two studies (3.7, 43%), telerehabilitation was used to support COVID-19 patient, both of which reported significant improvement in endurance, functional and physical condition of patients with telerehabilitation. However, no significant improvement was found in patients' pulmonary function parameters. In contrast, another study showed a significant improvement in shortness of breath and aerobic capacity of patients in the intervention group compared to the control. Conclusion(s): The results of the systematic review showed that a small number of small-scale studies on telerehabilitation have been performed for patients with COVID-19. However, it seems telerehabilitation has great potential to improve the functional, respiratory, physical condition and ultimately improve the quality of life of patients with COVID-19.Copyright © 2022 Isfahan University of Medical Sciences(IUMS).

Protocol for Preparing for Competitions in Different Time Zones

The pandemic affected all branches of the country's economy, all categories of services, but also performance sports. With it, competitions appeared postponed without a precise date or even totally canceled. In performance sports, a major role was played by the uncertainty of the biggest competition in an athlete's life, the Tokyo competition. It was a great challenge for the coach to organize his training periods, so as to bring the athletes in the best shape, but also for the doctors and the medical staff to work on an adequate recovery, to support the physical effort through the most well-rated supplements, always adapting to changes and not least for athletes to resist physically and mentally and to find the motivation to continue the routine to achieve their goal, that of reaching Tokyo.Copyright © 2022 Andreea-Elena Siminiceanu, published by Sciendo.

The Effect of Probable COVID-19 Infection on the National Football League Players' Performance and Endurance During the 2020 Season.

Objective The objective of this study was to assess whether the National Football League (NFL) players with probable coronavirus disease 2019 (COVID-19) during the 2020 season experienced a decline in athletic performance and endurance. Methods All players who were listed on the NFL's COVID-19 Injury Reserve (COVID-IR) list were screened for inclusion. Players were included in the study if they had spent ≥10 days on the COVID-19 IR list (which indicated a positive PCR test based on the NFL COVID-19 policies), had played in at least two games before and after going on the IR list, and primarily played an offensive or defensive position. The mean number of snaps played per game and Pro Football Focus (PFF) score per game were collected for each athlete, which served as surrogate measures of endurance and performance, respectively. The results were analyzed with players grouped by position, and then all players grouped as a whole. Within-group comparisons were performed via t-tests. Results A total of 78 players met the criteria for inclusion in the study. The overall mean PFF score pre-COVID-19 infection was 62.15 (SD: 6.93), while it was 61.73 (SD: 7.42) post-COVID-19 infection, showing a decrease of 0.42 after infection (n=78, p=0.33). The mean number of snaps played per game pre-COVID-19 infection was 38.99 (SD: 16.46) while it was 38.10 (SD: 17.05) post-COVID-19 infection, showing a decrease of 0.89 after infection (n=78, p=0.30). When grouped by position, statistically significant differences were seen with Defensive Backs' mean snaps played per game decreasing by 18.30 (n=6, p=0.03) and Defensive Linemen's mean PFF score decreasing by 3.77 points (n=21, p=0.03). Conclusion Based on our findings, COVID-19 infection negatively impacted endurance in Defensive Backs, and performance in Defensive Linemen. However, there was inconclusive evidence to show whether COVID-19 infection negatively impacted other positions when analyzed separately or all positions when analyzed together. Further studies with more participants are needed to fully assess the effects of COVID-19 on performance and endurance in elite athletes.

Impact of COVID-19 Infection on Cardiorespiratory Fitness, Sleep, and Psychology of Endurance Athletes-CAESAR Study.

COVID-19 has a deteriorating impact on health which is especially important for endurance athletes (EAs) who need to maintain continuity of training. The illness affects sleep and psychology, which influence sport performance. The aims of this study were: (1) to assess the consequences of mild COVID-19 on sleep and psychology and (2) to assess the consequences of mild COVID-19 on cardiopulmonary exercise test (CPET) results. A total of 49 EAs (males = 43, 87.76%; females = 6, 12.24%; age = 39.9 ± 7.8 years; height = 178.4 ± 6.8 cm; weight = 76.3 ± 10.4 kg; BMI = 24.0 ± 2.6 kg·m-2) underwent a maximal cycling or running CPET pre- and post-COVID-19 and completed an original survey. Exercise performance deteriorated after COVID-19 (maximal oxygen uptake, VO2max = 47.81 ± 7.81 vs. 44.97 ± 7.00 mL·kg·min-1 pre- and post-infection, respectively; p < 0.001). Waking up at night affected the heart rate (HR) at the respiratory compensation point (RCP) (p = 0.028). Sleep time influenced pulmonary ventilation (p = 0.013), breathing frequency (p = 0.010), and blood lactate concentration (Lac) (p = 0.013) at the RCP. The maximal power/speed (p = 0.046) and HR (p = 0.070) were linked to the quality of sleep. Stress management and relaxation techniques were linked with VO2max (p = 0.046), maximal power/speed (p = 0.033), and maximal Lac (p = 0.045). Cardiorespiratory fitness deteriorated after mild COVID-19 and was correlated with sleep and psychological indices. Medical professionals should encourage EAs to maintain proper mental health and sleep after COVID-19 infection to facilitate recovery.
