ABSTRACT

OBJECTIVES: Shift work is associated with various health challenges, including obesity and metabolic disturbances. To address these concerns, a randomised controlled clinical trial was conducted to evaluate the efficacy of a low-calorie meal replacement (MR) dietary intervention for dinner among shift workers with obesity. This study focuses on the qualitative aspects of this intervention, aiming to explore the experiences and perceptions of shift workers who participated in the trial. DESIGN: Following the completion of the intervention, semi-structured face-to-face or telephone interviews were conducted with a purposive sample of trial participants. Data analysis was inductive, thematic using NVivo V.10 software. SETTING: The intervention was conducted among shift workers with obesity in a private hospital in Sri Lanka and resulted in a modest decrease in weight. PARTICIPANTS: Using purposeful maximum variation sampling, we recruited eight healthcare shift workers who took part in a weight loss intervention. RESULTS: All participants expressed satisfaction with the MR meal for dinner, highlighting its positive impact on their well-being. Despite initial difficulties, strong determination and motivation by results supported adherence. Some participants suggested that the MR could be improved with sweeter taste and more flavour options. Few reported mild bloating at the beginning, but no serious side effects were noted. Participants felt lighter in their bodies due to weight loss. The method's simplicity was the most frequently reported benefit, making it feasible even during busy night shifts. Overall, participants highly recommended the intervention to others in need. CONCLUSION: Participants experienced weight loss by replacing their dinner with the MR. This study offers valuable insights for tailoring future workplace-based dietary interventions for this vulnerable population. TRIAL REGISTRATION NUMBER: ACTRN12622000231741.

ABSTRACT

Shift workers frequently experience alterations in their circadian rhythms, which are correlated with variations in hematological parameters. Changes in blood cells may be related to an individual's health status. Therefore, this study aimed to compare the relationship between shift work and changes in blood cells among a group of healthcare workers in Sri Lanka. A comparative cross-sectional study was conducted among healthcare workers, recruited by a stratified random sampling technique. Socio-demographic data were collected using a structured questionnaire. Venous blood samples were obtained and analyzed for the determination of total and differential blood cell counts. Descriptive statistics were used for the analysis of sociodemographic and hematological parameters. A sample of 37-day workers and 39 shift workers were included in the analysis. The mean ages (years) were not significantly different between the groups (36.8 ± 10.8 vs 39.1 ± 12.0; P = 0.371). Shift employees showed a significantly higher total mean white blood cell count (WBC) of 7548.75 mm-3 compared to day workers' 6869.19 mm-3 (P = 0.027). They also had higher mean absolute counts for all different WBC types (Neutrophils: 3949.2 vs 3557.7 , Lymphocyte: 2756.5 vs 2614.2 , Eosinophil: 317.6 vs 233.4 , Monocytes: 491.63 vs 432.51 , Basophils: 31.68 vs 29.22 ). Shift employees exhibited higher WBC counts than day workers at the same level of work experience. The length of shift work exposure revealed a positive link with neutrophil (r = 0.225 ) and eosinophil counts (r = 0.262 ), whereas these correlations were negative for day workers. Shift workers were associated with higher WBC counts in healthcare workers compared to their day-working counterparts.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate the influence of morning versus evening exercise on weight loss, cardiometabolic health, and components of energy balance. METHODS: A total of 100 inactive adults with overweight or obesity were randomized to morning exercise (AMEx; 06:00-09:00), evening exercise (PMEx; 16:00-19:00), or wait-list control (CON). AMEx and PMEx were prescribed 250 min·wk-1 of self-paced aerobic exercise for 12 weeks. Anthropometry and body composition, physical activity, and dietary intake were assessed at baseline, 6 weeks, and 12 weeks. Cardiorespiratory fitness (V̇O2 peak), resting metabolic rate, and blood markers were assessed at baseline and 12 weeks. Body composition and V̇O2 peak were also measured at 3- and 6-month follow-up. RESULTS: AMEx and PMEx lost weight during the intervention (mean [SD], AMEx, -2.7 [2.5] kg, p < 0.001; PMEx, -3.1 [3.4] kg, p < 0.001). V̇O2 peak significantly increased in both intervention groups, and these changes were different from CON (AMEx, +4.7 mL·kg-1 ·min-1 , p = 0.034; PMEx, +4.2 mL·kg-1 ·min-1 , p = 0.045). There were no between-group differences for resting metabolic rate or physical activity. At 12 weeks, total energy intake was significantly reduced in both AMEx and PMEx versus CON (AMEx, -3974 kJ, p < 0.001; PMEx, -3165 kJ, p = 0.001). CONCLUSIONS: Adults with overweight and obesity experience modest weight loss in response to an exercise program, but there does not appear to be an optimal time to exercise.

ABSTRACT

The objective of this study was to investigate changes in sedentary and active behaviors when previously inactive adults start exercising in the morning or evening. One-hundred adults with overweight or obesity (BMI ≥ 25 kg/m2) were recruited for a 12-week intervention and randomized to one of three groups: (i) morning exercise (AMEx; 0600-0900); (ii) evening exercise (PMEx; 1600-1900); or (iii) waitlist control. AMEx and PMEx were prescribed self-paced aerobic exercise to achieve a weekly total of 250 min via a combination of supervised and unsupervised training. Sedentary and active behavior times were measured at baseline, mid- and post-intervention using the multimedia activity recall for children and adults. Time spent engaging in physical activity was significantly increased from baseline at both mid- (+ 14-22 min·day-1) and post-intervention (+ 12-19 min·day-1), for AMEx and PMEx. At 12-weeks, participants in both morning and evening exercise groups reported increased time spent Sleeping (+ 36 and + 20 min·day-1, respecitively), and reduced time spent watching TV/playing videogames (- 32 and - 25 min·day-1, respectively). In response to an exercise stimulus, previously inactive adults make encouraging modifications in how they use their time, and the patterns of change are similar with morning and evening exercise.

ABSTRACT

The white blood cell (WBC) count increases significantly in reaction to infections and certain chronic diseases. Shift employment increases the risk for chronic low-grade inflammation and the progression of several chronic diseases. The objective of this study was to systematically evaluate the evidence from studies on total and differential WBC counts in shift employees. A literature search was performed in PubMed®, Web of Science, and Scopus databases using keywords for research published before March 1, 2022. A meta-analysis was conducted for total and differential WBC counts using a random-effects approach. A total of 25 studies covering a sample of 37,708 day and shift employees were included in this review. The studies represented America, Europe, East Asia, and Middle East. A significant increase in the total counts (×109/L) of WBC [mean difference (MD) = 0.43; 95% confidence interval (CI): 0.34-0.52; P < 0.001], lymphocytes (MD = 0.16; 95% CI: 0.02-0.30; P = 0.02), monocytes (MD = 0.04; 95% CI: 0-0.07; P = 0.03), and eosinophils (MD = 0.01; 95% CI: 0-0.01; P = 0.03) was observed in shift workers compared to the day counterparts. However, neutrophils and basophils were not significantly different between the groups. Shift work significantly increases the total and differential blood counts in peripheral circulation. Therefore, total and differential WBC counts represent a relatively inexpensive biomarker for diagnostics and prognostics of diseases in shift workers.

ABSTRACT

BACKGROUND: Shift work is considered a risk factor for a number of chronic health conditions including obesity. Weight reduction in obese patients lowers the risk for cardiovascular disease, diabetes, certain cancers, and mortality. Achieving a negative energy balance by providing low-calorie meal replacements is widely used for weight management. This study aims to evaluate the impact of a low-calorie "meal-replacement" on the weight and metabolic parameters of shift workers with obesity. METHODS: This trial will be conducted in a parallel, randomized controlled design for a period of 8 weeks. A total of 44 shift workers with body mass index over 25 kg/m2 will be recruited after assessing eligibility. Participants will be randomly assigned to the test and control groups on a 1:1 ratio. The intervention group (N = 22) will be provided with a low-calorie (~200 kcal) meal replacement shake as dinner, and the control group (N = 22) will continue their habitual diets. The visits and the evaluations will be done as follows: screening (visit 0), 4 weeks (visit 1), and 8 weeks (visit 2). Anthropometric measurements will be taken at 0, 4, and 8 weeks. Body composition, biochemical parameters, dietary intake, and physical activity will be assessed during the first and the last visit. OUTCOMES: The primary outcome will be the proportion of participants that had a 5% body weight loss from baseline. The secondary outcomes will be post-intervention changes in other metabolic parameters. DISCUSSION: To our knowledge, this is one of the first randomized controlled trials evaluating the effects of a meal replacement as the night meal for weight loss in shift workers with obesity. Moreover, improvement of metabolic parameters in shift workers will be an added benefit to this high-risk group.

ABSTRACT

OBJECTIVE: This study compared the body composition parameters between shiftworkers and nonshiftworkers in a hospital setting in Sri Lanka. METHODS: A comparative cross-sectional study was carried out among a sample of 78 health care workers, recruited by a stratified random sampling technique. Subjects underwent anthropometric and bioimpedentiometric analysis for body composition parameters. RESULTS: The mean (SD) body fat percentage (BF%) of shiftworking women (40.8 [SD, 6.8%]) was significantly higher than day-working women (36.7% [SD, 5.9%]) ( P < 0.05). Mean BF% between day and shift groups did not significantly differ (33.0% [SD, 6.9%] vs 32.4% [SD, 10.7%]). Body mass index and waist circumference were significantly higher among shiftworking women ( P < 0.05), whereas male workers showed the opposite trend. CONCLUSION: Prolonged exposure to shiftwork was associated with a higher BF%. Therefore, interventions for shiftworkers must be addressed, focusing on improving body composition.

ABSTRACT

Shift work, defined as work occurring outside typical daytime working hours, is associated with an increased risk for metabolic syndrome (MetS) due to several biological and environmental changes. The MetS refers to the clustering of several known cardiovascular risk factors, including insulin resistance, obesity, dyslipidemia, and hypertension. This systematic review aims to evaluate the literature on the association between shift work and the risk of MetS in employees of the health sector. A systematic search was conducted in PubMed, Web of Science, and Scopus databases using appropriate keywords for studies published before September 1, 2021. Eligible studies were those that compared the prevalence of MetS between day and shift healthcare workers; had a cross-sectional, case-control, or cohort study design; provided sufficient data for calculating odds ratios or relative risks with 95% confidence intervals; and articles in English. The Joanna Briggs Institute prevalence critical appraisal tool was used for quality analysis. Risk for MetS and related measures of effect size were retrieved from studies for meta-analysis. Twelve studies met the criteria for inclusion in the review and meta-analysis. Sample sizes ranged from 42 to 738, and the age range of subjects was between 18 and 65 years. Ten studies demonstrated high methodological quality, while two studies were of average quality. Ten out of 12 studies in the review demonstrated a higher risk in shift workers for developing MetS than day workers. The pooled OR of MetS in shift workers based on 12 studies was 2.17 (95% CI = 1.31-3.60, P = 0.003; I2  = 82%, P < 0.001). Shift workers exhibited more than a twofold increase in the chance of developing MetS in comparison with day workers.

ABSTRACT

OBJECTIVE: This study evaluated the association between shiftwork and metabolic syndrome (MetS) among a group of health care workers in Sri Lanka. METHODS: This study was in comparative cross-sectional design with 78 shiftworkers and nonshiftworkers 18 years and older. Data were collected through questionnaires, anthropometric measures, and blood tests. Metabolic syndrome was diagnosed based on the International Diabetes Federation and modified National Cholesterol Education Program, Adult Treatment Panel III criteria. RESULTS: The prevalence of MetS according to the International Diabetes Federation criteria was 16.2% and 36.6% among day workers and shiftworkers ( P = 0.043). According to modified National Cholesterol Education Program, Adult Treatment Panel III, 18.9% of day workers and 36.6% of shiftworkers had MetS ( P = 0.083). The best predictors of MetS were age (odds ratio, 1.07; 95% confidence interval, 1.02-1.12; P = 0.008) and shiftwork (odds ratio, 2.78; confidence interval, 0.90-8.72; P = 0.076). CONCLUSION: Shiftworkers had a more than twofold increased risk of developing MetS than day workers. Intervention targeting diet, physical activity, awareness sessions, and health screenings should be promoted.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a viral pulmonary infection that can progress to cytokine storm syndrome because of widespread dysregulated inflammatory response. Many patients at risk for severe COVID-19 manifestation have been identified as those with preexisting conditions of pulmonary origin, as well as conditions that impair appropriate immune response, such as obesity. OBJECTIVES: The aim of this study is to describe the manifestation, clinical course, and inflammatory biomarker milieu of COVID-19 in patients with obesity. SETTING: University Hospital Philadelphia, Pennsylvania. METHODS: In this retrospective cohort study, 600 patients who were positive for COVID-19 were stratified by World Health Organization (WHO) obesity class and their presenting symptoms, disease biomarkers, demographics, and outcomes (intubation rate, intensive care unit [ICU] admission, length of stay [LOS], and mortality) were investigated. RESULTS: Age was inversely related to obesity class; patients of obesity class III presented 12.9 years younger than patients of normal weight (P < .0001). Initial ferritin lab values were negatively correlated with increasing obesity class (P = .0192). Normal or near-normal lymphocyte profile was noted in patients with obesity compared with patients without obesity (P = .0017). Patients with obesity had an increased rate of ICU admission (P = .0215) and increased length of stay (P = .0004), but no differences in intubation rate (P = .3705) or mortality (P = .2486). CONCLUSION: Patients with obesity were more likely to present to the hospital at a younger age, with reduced levels of COVID-19 related biomarker disturbances, and increased LOS and ICU admission rates, although were not at increased risk for mortality.

ABSTRACT

BACKGROUND: To improve compliance and adherence to exercise, the concept of temporal consistency has been proposed. Before- and after-work are periods when most working adults may reasonably incorporate exercise into their schedule. However, it is unknown if there is an association between the time-of-day that exercise is performed and overall physical activity levels. METHODS: Activity was assessed over 1 week in a sample of 69 active adults (n = 41 females; mean age = 34.9 [12.3] y). At the end of the study, participants completed an interviewer-assisted questionnaire detailing their motivation to exercise and their exercise time-of-day preferences. RESULTS: Participants were classified as "temporally consistent" (n = 37) or "temporally inconsistent" (n = 32) exercisers based on their accelerometry data. The "temporally consistent" group was further analyzed to compare exercise volume between "morning-exercisers" (n = 16) and "evening-exercisers" (n = 21). "Morning-exercisers" performed a greater volume of exercise than "evening-exercisers" (419 [178] vs 330 [233] min by self-report; 368 [224] vs 325 [156] min actigraph-derived moderate to vigorous physical activity, respectively). CONCLUSIONS: Our findings suggest that active individuals use a mixture of temporal patterns to meet PA guidelines. Time-of-day of exercise should be reported in intervention studies so the relationship between exercise time-of-day, exercise behavior, and associated outcomes can be better understood.

ABSTRACT

Background/Objectives: Characterizing compensatory and adaptive responses to exercise assists in understanding changes in energy balance and health outcomes with exercise interventions. This study investigated the effects of a short-term exercise intervention (combining high intensity interval (HII) and continuous exercise) on (1) gastric emptying, appetite and energy intake; and (2) other adaptive responses including cardiorespiratory fitness, in inactive men with overweight/obesity. Methods: Fifteen men (BMI: 29.7 ± 3.3 kg/m-2) completed a 4-wk supervised exercise intervention, consisting of 5 exercise sessions per week alternating between HII (30 s at 100% VO2max followed by 30 s recovery) and continuous (at 50% VO2max) training on a cycle ergometer, progressing from 30 to 45 min session duration. Gastric emptying (13C-octanoic acid breath test), appetite (visual analog scale), energy intake (ad libitum lunch meal), body composition (air displacement plethysmography), non-exercise activity (accelerometery) VO2max, blood pressure, and fasting concentrations of glucose, insulin, and ghrelin were measured before and after (≥48 h) the intervention. Results: Gastric emptying, glucose, insulin and ghrelin were unchanged, but energy intake at the ad libitum lunch test meal significantly increased at post-intervention (+171 ± 116 kcal, p < 0.01). Body weight (-0.9 ± 1.1 kg), waist circumference (-2.3 ± 3.5 cm) and percent body fat (-0.9 ± 1.1%) were modestly reduced (P < 0.05). VO2max increased (+4.4 ± 2.1 ml.kg.min-1) by 13% and systolic (-6.2 ± 8.4 mmHg) and diastolic (-5.8 ± 2.2 mmHg) blood pressure were significantly reduced (P ≤ 0.01 for all). Conclusions: Four weeks of exercise training did not alter gastric emptying, indicating gastric emptying may only adapt to a higher volume/longer duration of exercise or changes in other characteristics associated with regular exercise. The combination of HII and continuous exercise training had beneficial effects on body composition, cardiorespiratory fitness, and blood pressure and warrants further investigation in larger randomized controlled trials.

ABSTRACT

BACKGROUND AND AIMS: Figure Rating Scales (FRS) are psychometric instruments developed to measure individual's perception of physical appearance and subsequently, to determine the level of body dissatisfaction. The following systematic review summarizes existing FRSs and the techniques used to development them. METHODS: A systematic search was conducted in the following databases; PubMed®, Web of Science®, Scopus® using key words "figure rating scale" AND "Stunkard". RESULTS: From 466 potentially relevant articles, 24 publications were included, 22 publications reporting original FRSs with the other two scales being modifications of the original for children and babies. Fifteen were figural drawings or silhouettes and nine were developed by photographic techniques, video methods or using computer software. Most of the figural scales were applicable for adults and consisted of nine images. Ten of the 15 figural scales were without facial features and four scales had minimal facial features. Technological advancements including 3D modeling have played a pivotal role in the development of FRSs. CONCLUSIONS: FRSs have been developed by a mix of traditional and modern techniques. The development and validation of ethnic specific FRSs using modern technology should be the priority for future studies.

ABSTRACT

The aim of this study was to investigate short- and long-term compensatory effects on dietary intake following high intensity interval training (HIIT) compared with usual care moderate intensity continuous training (MICT) during and following a cardiac rehabilitation program. This study investigates secondary outcomes of a clinical trial. Ninety-three participants with coronary artery disease enrolled in a 4-week cardiac rehabilitation program, were randomised to 1) 4x4-minute HIIT; or 2) 40-min of MICT (usual care). Patients were instructed to complete 3 weekly sessions (2 supervised, 1 home-based) for 4-weeks, and 3 weekly home-based sessions thereafter for another 48-weeks. Dietary intake was measured by telephone-based 24-h recall over 2 day at baseline, 4-weeks, 3-months, 6-months, and 12-months. Three-Factor Eating Questionnaire was used to measure dietary behaviour and Leeds Food Preference Questionnaire used to measure food preferences. Appetite was assessed by a visual analogue scale and appetite-regulating hormones. There was no change over the study period or differences between groups for daily energy intake at 4-weeks or 12-months. There were also no group differences for any other measures of dietary intake, fasting hunger or appetite-related hormones, dietary behaviour, or food preferences. These findings suggest that compared to moderate intensity exercise, HIIT does not result in compensatory increases of energy intake or indicators of poor diet quality. This finding appears to be the same for patients with normal weight and obesity. HIIT can therefore be included in cardiac rehabilitation programs as an adjunct or alterative to MICT, without concern for any undesirable dietary compensation.

ABSTRACT

BACKGROUND AND AIMS: To examine the effects of aerobic training (AT) and resistance training (RT) compared to standard care on glycemic control in South Asian Sri Lankan adults with Type 2 Diabetes Mellitus (T2DM). METHODS: Randomized controlled trial (RCT) with parallel-group design recruited 86 sedentary Sri Lankans (aged 35-65 years) with T2DM into aerobic training (AT, n = 28), resistance training (RT, n = 28) and control (CN, n = 30) groups. Supervised progressive exercise training consisting of 75 min per session, 2 days per week for 12 weeks was conducted. The primary outcome was pre- and post-intervention absolute change in hemoglobin A1c (HBA1c). Secondary outcomes were serum lipids, liver enzymes, chronic inflammatory status, anthropometry, body composition and blood pressure. RESULTS: The absolute change in HbA1c of RT vs. CN was -0.08% (95% CI, 0.8% to -0.7%, p = 0.8) and AT vs. CN was -0.22% (95% CI, 0.95% to -0.5%). Subgroup analysis (n = 49) with a high baseline HbA1c (>7.5%), absolute reduction in HbA1c in exercise groups were statistically significant (RT vs. CN was -0.37%; 95% CI 1.3% to -0.6%, p = 0.04 and AT vs. CN was -0.57%; 95% CI 1.7% to -0.6%, p = 0.03). The effect sizes (total and subgroup HbA1c >7.5%) ranged from 0.7 to 1.0 in AT, 0.4 to 1.1 in RT compared to 0.35 to 0.6 for the CN. Secondary outcomes did not significantly differ among groups. CONCLUSIONS: Exercise training 2 days/week improved glycemic control in Sri Lankan adults with T2DM and the effects were significant in high baseline HbA1c (>7.5%) groups (RT > AT).

ABSTRACT

The sensory profile, referring to sight, smell, taste, hearing, and touch, plays an essential role in optimizing the habitual intake of energy and macronutrients. However, specific populations, such as older adults, are known to have impaired energy intake. In this paper, the relevance of sensory impairments in this older population is described, and the extent to which nutritional and physical activity interventions can modulate these sensory responses when food intake is insufficient is explored. With aging, all senses deteriorate, and in most cases, such deteriorations diminish the nutritional response. The only exception is sight, for which both positive and negative impacts on nutritional response have been reported. From a prevention perspective, nutritional interventions have been understudied, and to date, only hearing is known to be positively affected by a good nutritional profile. In comparison, physical activity has been more frequently studied in this context, and is linked to an improved preservation of 4 senses. Regarding treatment, very few studies have directly targeted sensory training, and the focus of research has tended to be on nutrition and physical activity intervention. Sensory training, and nutritional and physical activity treatments all have beneficial effects on the senses. In the future, researchers should focus on exploring gaps in the literature specifically concerning prevention, treatment, and sensory response to understand how to improve the efficacy of current approaches. In order to maintain sensory acuity and recover from sensory impairment, the current state of knowledge supports the importance of improving nutritional habits as well as physical activity early on in life. A combined approach, linking a detailed lifestyle profile with the assessment of numerous senses and one or more interventional approaches (nutrition, physical activity, sensory training, etc.), would be required to identify effective strategies to improve the nutritional state of older individuals.

ABSTRACT

Background Interdisciplinary education (IDE) has been proposed as a means to improve patient safety by enhancing the performance of diverse health care teams. The improved camaraderie between members of different specialties may enhance communication and can foster a more supportive and positive work environment. Objective This study was aimed to assess the effect of IDE on the procedural skills of general surgery (GS) and emergency medicine (EM), as well as the perceptions that GS and EM residents have of one another. Methods EM and GS residents participated in two separate IDE sessions (4 months apart) designed to teach extended focused assessment with sonography in trauma (e-FAST), tube thoracostomy, and complex wound closure. Surveys were administered to determine the effects that IDE had on confidence in performing bedside procedures, perceptions of IDE, and perceptions of one another's specialty. Survey responses were recorded using a 5-point Likert's scale. Results Nine GS residents and 10 EM residents participated in the entire study. Significant improvements in the confidence levels of performing bedside procedures were noted among both groups of residents. We also report a significant improvement in the perceived respect and communication between EM and GS residents. Conclusions Although further studies with a larger sample size are required, we have shown that IDE can improve the confidence levels of EM and GS residents in performing tube thoracostomy, e-FAST, and complex wound closure. These IDE sessions also improve the perceptions that the residents have of one another. IDE is a useful tool and may translate into improved consultation, collaboration, and patient care.

ABSTRACT

BACKGROUND: The time of day that people exercise could have an influence on the efficacy of exercise for weight loss, via differences in adherence and/or physiological adaptations. However, there is currently no evidence to support an optimal time of day for exercise to maximise efficacy. PURPOSE: To examine the feasibility and acceptability of prescribed morning and evening exercise. METHODS: Twenty inactive, overweight adults aged 18-60 years were recruited for a 12-week intervention and randomized to one of three groups using a 2:2:1 random allocation ratio: i) morning exercise (AM; n = 9); ii) evening exercise (PM; n = 7); or iii) waitlist control (CON; n = 4). Exercise groups were prescribed self-paced walking or running on a treadmill to achieve a weekly total of 250 min. Feasibility and acceptability data were collected, and physiological and behavioural outcomes associated with energy balance were measured at baseline, mid- and post-intervention. RESULTS: Attrition was low (n = 2 dropped out), with high measurement completion rates (>80%). The intervention groups had high adherence rates to exercise sessions (94% and 87% for the AM and PM groups, respectively). No adverse events resulting from the intervention were reported. Both intervention groups displayed improvements to their cardiometabolic risk profile; cardiorespiratory fitness improved by 5.2 ±â€¯4.7, and 4.6 ±â€¯4.5 mL kg-1.min-1 and body fat percentage reduced by 1.2 ±â€¯1.4, and -0.6 ±â€¯1.2% for AM and PM groups, respectively. CONCLUSION: This feasibility study provides evidence that morning and evening exercise interventions are feasible, and also provides justification for a large-scale randomized controlled trial. TRIAL REGISTRATION: This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12616000457448p, 7/4/2016).

ABSTRACT

Optimising dietary energy intake is essential for effective sports nutrition practice in rugby athletes. Effective dietary energy prescription requires careful consideration of athletes' daily energy expenditure with the accurate prediction of resting metabolic rate (RMR) important due to its influence on total energy expenditure and in turn, energy balance. This study aimed to (a) measure rugby athletes RMR and (b) report the change in RMR in developing elite rugby players over a rugby preseason subsequent to changes in body composition and (c) explore the accurate prediction of RMR in rugby athletes. Eighteen developing elite rugby union athletes (age 20.2 ± 1.7 years, body mass 101.2 ± 14.5 kg, stature 184.0 ± 8.4 cm) had RMR (indirect calorimetry) and body composition (dual energy x-ray absorptiometry) measured at the start and end of a rugby preseason ∼14 weeks later. There was no statistically significant difference in RMR over the preseason period (baseline 2389 ± 263 kcal·day-1 post 2373 ± 270 kcal·day-1) despite a significant increase in lean mass of +2.0 ± 1.6 kg (P < 0.01) and non-significant loss of fat mass. The change in RMR was non-significant and non-meaningful; thus, this study contradicts the commonly held anecdotal perception that an increase in skeletal muscle mass will result in a significant increase in metabolic rate and daily energy needs. Conventional prediction equations generally under-estimated rugby athletes' measured RMR, and may be problematic for identifying low energy availability, and thus updated population-specific prediction equations may be warranted to inform practice.

ABSTRACT

Introduction: Exercise rehabilitation/training is integral in the prevention and management of chronic, lifestyle-related diseases. Poor long-term adherence to exercise by patients is a challenging problem for health professionals. Despite the evidence of appropriate supervision with improved exercise adherence, the supervision process is not adequately described in the literature. Further, the co-existing Technical and Cognitive Behavioral components of exercise supervision are commonly described separately.Methodology: The literature search included (a) reviewing the Technical Domain (TD) of exercise prescription; and (b) Cognitive Behavioral Domain (CBD) of exercise adoption and adherence. CB theories were selected based upon their scientific evidence base demonstrating efficacy in intervention trails. The FITTSBALL tool was developed combining TD and CBD identifying multiple interactions. The tool was applied to 3 case scenarios to demonstrate efficacy.Results: "FITTSBALL" combined the technical domain of "FITT" (Frequency, Intensity, Time, and Type of exercise) and the cognitive behavioral domain (combining five theories and additional constructs) explained by "SBALL" (Stage of change, Belief and Ability of the client, Limitations and Life satisfaction). The tool describes the exercise supervision process and its associations as a three dimensional "sphere" traveling in a particular trajectory. Case scenarios on exercise adoption, maintenance, and relapse are described.Discussion: The "FITTSBALL" tool developed and detailed in this article provides both a meaningful description of supervision and a logical, generic framework for exercise prescription, concentrating on adherence and behavior change. The tool could be used by all staff responsible for supervision. This approach describes how the technical "FITT" principle of prescribing exercise can coexist with a range of cognitive and behavioral theories that have been posited to describe approaches to encourage behavior change and support adherence to such changes. Many such approaches have been widely studied over recent decades using interventional trials.Conclusion: "FITTSBALL" is a logical, generic framework for exercise prescription, concentrating on adherence and behavior change. To the best of our knowledge, such a comprehensive and coherent tool has not been presented to date.Implications for rehabilitationExercise training is integral in the management of chronic, lifestyle-related diseases, but long term adherence is a challenge.Exercise supervision improves adherence, but exercise supervision process is not adequately described in the literature.The tool "FITTSBALL" describes the supervision process and provides a logical, generic framework for exercise prescription and maintaining adherence to the behavior.The dynamic tool combines the traditional technical domain of "FITT" with the cognitive behavioral domain explained by "SBALL".
