Response of skin temperature, blood ammonia and lactate during incremental exercise until exhaustion in elite athletes.

The study aimed to evaluate the lower limb skin temperature (Tsk) and blood concentrations of lactate (LA) and ammonia (NH3) during exercise and recovery. Eleven elite sprint athletes (25 ± 3.4 yrs) and 11 elite endurance athletes (24.45 ± 5.4 yrs) performed an incremental running test until exhaustion. Body composition was estimated using the DXA method. Thermograms of the anterior and posterior surfaces of the lower limbs were recorded at rest, before each test stage (every 3 min, starting from 10 km h-1 and increasing by 2 km h-1), and in the 5th, 10th, 15th, 20th, and 30th minute of recovery. Endurance athletes had a higher maximum oxygen uptake than sprint athletes (5.0 ± 0.7 vs 4.3 ± 0.4 l·kg-1, p = 0.018), lower percentage of lean content (79 ± 2 vs 83 ± 2%, p < 0.001), and a higher percentage of fat content in the lower limbs (17 ± 2 vs 12 ± 2%, p < 0.001). In both groups, a significant decrease in Tsk was observed compared to resting value (endurance athletes-31.5 ± 0.6 °C; sprint athletes-32.3 ± 0.6 °C), during exercise (p < 0.001) and rewarming during recovery (p < 0.001). However, endurance athletes had a lower Tsk than sprint athletes at the exhaustion point (30.0 ± 1.1 vs 31.6 ± 0.8 °C, p < 0.05) and the pattern of change in Tsk differed between groups (p < 0.001). Tsk in the endurance athletes group decreased throughout the exercise protocol and returned more rapidly to initial values during recovery, while Tsk in the sprint group stabilised between moderate intensity and exhaustion, recovering more slowly after exercise. Both LA (endurance athletes-max 10.2 ± 1.5; sprint athletes-max 10.1 ± 1.4 mmol⋅L-1, p < 0.001) and NH3 (endurance athletes-max 75.6 ± 11.5; sprint athletes-max 76.7 ± 9.0 mmol⋅L-1, p < 0.001) increased during exercise and decreased during recovery (p < 0.001). During exercise, lower levels and slower increases in LA were observed during exercise in the endurance athletes' group (p < 0.05). A negative correlation was revealed between Tsk and fat percentage (r = -0.43 to -0.71, p < 0.05). Tsk was positively correlated with LA during recovery (r = 0.43 to 0.48, p < 0.05), and negatively during recovery (r = -0.45 to -0.54, p < 0.05). Differences between groups in maximum aerobic capacity, the pattern of change in Tsk, and the correlation between Tsk and LA suggest that individuals who decrease less Tsk during exercise and higher Tsk during recovery are those with better aerobic capacity. In addition, athletes with less body fat dissipate heat from their tissues more efficiently.

Assessment of the Dietary Intake and Nutritional Status of Polish Professional Futsal Players: A Descriptive Study-Do Futsal Players Require Nutritional Education?

Futsal is a discipline with high training and nutritional requirements. Despite growing research interest in athletes' diet and nutritional status, no studies have examined Polish male futsal players. Therefore, the aim of this descriptive study was an assessment of the dietary intake and nutritional status in a selected group of futsal players. The study comprised 11 members of a top Polish futsal team (aged 26 ± 3.62 years). Dietary intake was assessed using a standardized 3-day food record. Body composition, total energy expenditure, physical fitness level, and concentrations of the biochemical indices of each participant were estimated. The energy availability in the diet was lower than recommended. Moreover, low consumption of carbohydrates was stated, as well as an inadequate intake of Vitamins E and D. Higher protein and cholesterol intake than recommended were also observed. To conclude, our results point to the need for educating athletes and coaches, particularly teaching about proper food choices, promoting quality foods, and, in some cases, using individual dietary plans to meet energy and nutrient needs. Nutrition education would help to improve their dietary and health habits and optimize their performance in sports training.

The use of thermal imaging for monitoring the training progress of professional male sweep rowers.

This study assesses the thermal profile of the skin in highly trained rowers and investigates the relationship between resting skin temperature (Ts) and the muscle peak torque (PT) measured in statics at the beginning (autumn) and the end (spring) of the preparatory period. Ten professional male sweep rowers, members of the Polish national rowing team, were investigated. A thermal imaging camera was used to analyze the Ts. The PT of the muscles involved in the rowing cycle were measured isometrically. No significant temperature asymmetries were found, except in front of arms after exercise in the spring (p = 0.0228). In contrast, the PT test in the autumn confirmed the significant asymmetry of the knee joint extensors (p = 0.0192). In spring compared to autumn, Ts in many areas of the body were slightly higher, as was PT of underlying muscles. Significant correlations between resting Ts and PT of the underlying muscles were found. Thermal imaging makes it possible to observe changes in skin temperature and symmetry before and after exercise. At this stage, it does not appear to be a method that, without supporting of other methods such as those assessing muscle function, will allow monitoring of training progress.

The Evaluation of Functional Abilities Using the Modified Fullerton Functional Fitness Test Is a Valuable Accessory in Diagnosing Men with Heart Failure.

The assessment of functional abilities reflects the ability to perform everyday life activities that require specific endurance and physical fitness. The Fullerton functional fitness test (FFFT) seems to be the most appropriate for assessing physical fitness in heart failure (HF) patients. The study group consisted of 30 consecutive patients hospitalized for the routine assessment of HF with a reduced ejection fraction (HFrEF). They formed the study group, and 24 healthy subjects formed the control group. Each patient underwent a cardiopulmonary exercise test (CPET), transthoracic echocardiography and FFFT modified by adding the measurement of the handgrip force of the dominant limb with the digital dynamometer. The HF patients had significantly lower peak oxygen uptake (peakVO2), maximal minute ventilation, and higher ventilatory equivalent (VE/VCO2). The concentrations of B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) were significantly higher in the study group. The results of all the FFFT items were significantly worse in the study group. FFFT parameters, together with the assessment of the strength of the handgrip, strongly correlated with the results of standard tests in HF. FFFT is an effective and safe tool for the functional evaluation of patients with HFrEF. Simple muscle strength measurement with a hand-held dynamometer can become a convenient and practical indicator of muscle strength in HF patients.

Temperature and creatine kinase changes during a 10d taper period in sprinters.

Objective.The aim of this prospective cohort study, performed during a 10 d training camp, was to analyze the effect of a series of successive speed-power training sessions on the concurrent circadian changes in resting leg skin temperature and blood creatine kinase (CK) levels and to determine the correlation between them.Approach. Seventeen elite sprinters, aged 22-31 years, were examined. Every morning and evening, capillary blood samples were drawn to assay CK levels. Lower limb skin temperature was measured simultaneously, and thermal images were taken using an infrared camera.Main results. From the first day of the training camp, the base temperature levels began to drop to obtain a significant reduction from the 6th day (male) and from the 8th day (female) to the end of the camp. Simultaneously, CK levels increased in the male group from 8th to the end of the camp, but it did not change significantly in females. Regarding the circadian rhythm, the CK levels always rose during the day and declined during the night. The temperature decreased during the day and increased during the night until the 6th day. After that, the temperature changed oppositely till the end of camp, i.e. it increased during the day and decreased during the night. This could suggest that the training microcycle should last about a week because after this time there may be a disturbance in the temperature circadian rhythm and a significant CK accumulationSignificance. Multi-day speed-power training induced a progressive reduction in resting skin temperature and an elevation in CK levels. It also altered the circadian rhythm of the body skin temperature, which may indicate that after about 6 d of regular exercise, physiological deregulation may occur.

Sclerostin and bone remodeling biomarkers responses to whole-body cryotherapy (- 110 °C) in healthy young men with different physical fitness levels.

We investigated the effects of single and repeated exposures to whole-body cryotherapy on biomarkers of bone remodeling and osteo-immune crosstalk: sclerostin, osteocalcin (OC), C-terminal cross-linked telopeptide of type I collagen (CTx-I), osteoprotegerin (OPG) and free soluble receptor activator for nuclear factor κ B ligand (sRANKL). The study included 22 healthy males, grouped in high physical fitness level (HPhL) and low physical fitness level (LPhL), all undergone 10 consecutive sessions in a cryogenic chamber (- 110 °C). We observed a significant time-effect on sclerostin (p < 0.05), OC (p < 0.01), CTx-I (p < 0.001), OC/CTx-I (p < 0.05), and significant differences in sRANKL between the groups (p < 0.05) after the 1st cryostimulation; a significant time-effect on OC (p < 0.001) and OC/CTx-I (p < 0.001) after the 10th cryostimulation, and a significant time-effect on CTx-I (p < 0.001) and OC/CTx-I (p < 0.01) after 10 sessions of WBC. In conclusion, in young men, the first exposure to extreme cold induced significant changes in serum sclerostin. The changes in sRANKL, between groups, suggest that fitness level may modify the body's response to cold. The effects of the first stimulus and the whole session are not identical, probably due to the physiological development of habituation to cold.

Sexual dimorphism of lumbar lordosis and lumbar spine mobility during the period of progressive development.

Objective: The objective of this paper is to present possible differences in spondylometric dimorphic characteristics of lumbar spine in the period of progressive development. Material and methods: The research material included 24,517 individuals of both sexes aged from 3 to 25. Individuals that showed abnormal structure of the motor system and individuals reporting pain in the joints of the spine were excluded. Spondylometric research was carried out using the Penny & Giles electrogoniometric measuring system. Significance tests concerning position measurements (Student's t-test, Welch's t-test) were used as well as biometric profiles formed on the basis of Mollison index for each characteristic in the studied period of ontogenesis. The progress of development of the examined spondylometric characteristics in both sex groups was calculated on the basis of expressing the size of the feature in successive age groups as a percentage of its final size. Using the linear and polynomial regression models, the developmental lines of the studied spondylometric parameters were obtained in males and females. Results: In the development process of the studied spondylometric parameters, dimorphic diversity can be observed essentially only in adolescence. In general, in the whole studied period of ontogenetic development, the greater range of lumbar spine mobility is found in females. Minor sexual dimorphism is also evident in the dynamics of development and in the stage of development of the majority of examined characteristics in individual age ranges in relation to the final values, for the benefit of the female sex.

Effects of marathon race on selected myokines and sclerostin in middle-aged male amateur runners.

In recent years, there has been increasing interest in the homeostatic response to extreme exercises, especially in the integrated function of muscle and bone. The aim of this study was to evaluate the effects of a marathon race on selected myokines and sclerostin in 10 male recreational runners (mean age 41 ± 7.7 years). Body composition, bone mineral density (BMD), and the serum concentration of myostatin, irisin, sclerostin, osteoprotegerin (OPG), 25-hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH), high-sensitivity interleukin-6 (hsIL-6), tumor necrosis factor α (TNFα), high-sensitivity C-reactive protein (hsCRP) and myoglobin, were determined 24 h before and 24 h and 72 h after a marathon race. Post-marathon increases were observed in the levels of myostatin (1.2-fold), OPG (1.5-fold), and PTH (1.3-fold), hsIL-6 (1.9-fold), myoglobin (4.1-fold), hsCRP (fivefold), TNFα (2.6-fold), after 24 h; and in myostatin (1.2-fold), irisin (1.1-fold), sclerostin (1.3-fold), OPG (1.3-fold), and PTH (1.4-fold), hsIL-6 (1.4-fold), TNFα (1.9-fold), after 72 h compared to the baseline level. The results show that in response to the marathon run, a complex network of endocrine interactions is initiated. Further research is needed to fully elucidate the long-term impact of prolonged high intensity exercise on the human body.

Manual Therapy (Postisometric Relaxation and Joint Mobilization) in Knee Pain and Function Experienced by Patients with Rheumatoid Arthritis: A Randomized Clinical Pilot Study.

OBJECTIVES: The purpose of this study was to evaluate the impact of manual therapy on the management of rheumatoid arthritis (RA) patients with knee pain. MATERIALS AND METHODS: This was a small, randomized clinical pilot study. Subjects were 46 patients with diagnosed RA, randomly assigned to the manual therapy group (postisometric relaxation and joint mobilization) or control group (standard exercise). Subjects in each group had 10 sessions of interventions, once a day with one day break after the sixth day. Outcomes included the pain intensity of knee, Knee Society Score, Oxford Knee Score, and Health Assessment Questionnaire. RESULTS: There were no statistically significant differences between groups, except for the pain intensity of the knee. CONCLUSIONS: This study suggests that manual therapy (postisometric relaxation and joint mobilization) may have clinical benefits for treating knee pain and function in rheumatoid patients. Further extended studies are expected to determine the effectiveness of manual therapy in RA patients with knee pain.

Effects of whole-body cryotherapy on 25-hydroxyvitamin D, irisin, myostatin, and interleukin-6 levels in healthy young men of different fitness levels.

Skeletal muscle and adipose tissue play an important role in maintaining metabolic homeostasis and thermogenesis. We aimed to investigate the effects of single and repeated exposure to whole-body cryotherapy in volunteers with different physical fitness levels on 25-hydroxyvitamin D (25(OH)D) and myokines. The study included 22 healthy male volunteers (mean age: 21 ± 1.17 years), who underwent 10 consecutive sessions in a cryogenic chamber once daily (3 minutes, -110 °C). Blood samples were collected before and 30 minutes and 24 hours after the first and last cryotherapy sessions. Prior to treatment, body composition and physical fitness levels were measured. After 10 cryotherapy treatments, significant changes were found in myostatin concentrations in the low physical fitness level (LPhL) group. The 25(OH)D levels were increased in the high physical fitness level (HPhL) group and decreased in the LPhL group. The HPhL group had significant changes in the level of high-sensitivity interleukin-6 after the first treatment. The LPhL group had significant changes in 25(OH)D, irisin, and myostatin levels after the tenth treatment. Our data demonstrated that in healthy young men, cryotherapy affects 25(OH)D levels, but they were small and transient. The body's response to a series of 10 cryotherapy treatments is modified by physical fitness level.

Beneficial Effects of Pulsed Electromagnetic Field during Cast Immobilization in Patients with Distal Radius Fracture.

To assess whether pulsed electromagnetic field therapy during cast immobilization of distal radius fractures has beneficial effects on pain and limb function, the study included 52 patients (mean age 60.8 ± 15.0 years) with distal radius fractures treated with cast immobilization. Patients were allocated to a pulsed electromagnetic field group (n = 27) or a control group (n = 25). Pain; forearm and arm circumference; range of motion; disabilities of the arm, shoulder, and hand score; and touch sensation were evaluated on the day of the plaster cast dressing and 3 and 6 weeks after. In comparison to the control group, the pulsed electromagnetic field group reported significant changes after 3 and 6 weeks of treatment: lower pain levels (p=0.0052; p < 0.0001, respectively), greater mobility of upper-limb joints, improvement in exteroceptive sensation, and reduction in disability of the upper limb (disabilities of the arm, shoulder, and hand) (p=0.0003; p < 0.0001, respectively). Our results suggest that early addition of pulsed electromagnetic field treatment, during cast immobilization of distal radius fractures, has beneficial effects on the pain, exteroceptive sensation, range of motion, and daily functioning of patients.

Hand-eye coordination, movement reaction time and hand tactile sensitivity depending on the practiced sports discipline.

BACKGROUND: Practicing competitive sports, particularly those disciplines in which the upper limbs are involved in the movement, develops physical fitness and its special feature, namely the hand-eye coordination. Some sport disciplines require manipulation of an object. Using a sport equipment every day, several times, during training and matches must affect the characteristics of the skin of the palmar side of the hand. It may be presumed to affect the tactile sensitivity of the skin. The aim of the study was to determine the relationship between hand-eye coordination and tactile sensitivity in basketball, volleyball, handball, football and combat sports players as compared to those who do not practice competitive sports. METHODS: Overall, 121 men were subject to tests. The tactile sensitivity threshold was determined at three points of the palmar side of the hand using The Touch-Test™ Sensory Evaluators esthesiometer. The second test involved hand-eye coordination of the upper limbs and it was carried out using cross-type machine. RESULTS: The greatest tactile sensitivity was shown in combat sports players. These players also demonstrated the shortest reaction time and the lowest number of errors in the motor coordination test. The correlation between tactile sensitivity and coordination was found to be the strongest in subjects not practicing sports. CONCLUSIONS: The most interesting finding is that in the group of athletes using hands (team sports games and combat sports) the correlation between movement coordination and tactile sensitivity is weaker.

Is the whole-body cryotherapy a beneficial supplement to exercise therapy for patients with ankylosing spondylitis?

BACKGROUND: The treatment of ankylosing spondylitis (AS) patients requires a combination of non-pharmacological (education, exercise and physical therapy), as well as pharmacological treatment modalities. The optimal management of AS still remains unresolved. OBJECTIVE: The aim was to measure and compare the effects of whole-body cryotherapy (WBC) at -110∘C and at -60∘C and exercise therapy alone on disease activity and the functional parameters of patients with AS. METHODS: Ninety-two patients were allocated to three groups: with WBC at -110∘C or at -60∘C (each concurrent with exercise therapy), or exercise therapy alone. Disease activity and the functional parameters of the patients were measured at study entry and at the end of the 8-day treatment. RESULTS: Supervised therapy, irrespective of the program, led to a significant reduction in disease activity (Bath Ankylosing Spondylitis Disease Activity Index: BASDAI, Ankylosing Spondylitis Disease Activity Score: ASDAS-CRP), disease-related back pain, fatigue, duration and intensity of morning stiffness and a significant improvement in the patient's functional capacity (Bath Ankylosing Spondylitis Functional Index: BASFI), spine mobility (Bath Ankylosing Spondylitis Metrology Index: BASMI) and chest expandability, with no changes in the levels of CRP. It has been demonstrated that following therapy, the group that underwent cryotherapy at -110∘C manifested significantly reduced disease activity (BASDAI) compared with exercise therapy only (p= 0.024). CONCLUSION: Adding cryotherapy at -110∘C to exercise therapy led to significantly reduced disease activity expressed in BASDAI, compared with exercise therapy alone.

The Effect of Whole-Body Cryotherapy at Different Temperatures on Proinflammatory Cytokines, Oxidative Stress Parameters, and Disease Activity in Patients with Ankylosing Spondylitis.

PURPOSE: Patients with ankylosing spondylitis (AS) have increased production of proinflammatory cytokines, increased oxidants, and decreased antioxidant capacity. The aim of this study was to determine the effect of whole-body cryotherapy (WBC) at -110°C and -60°C, on disease activity, selected proinflammatory cytokines, and oxidative stress in patients with AS. METHODS: Sixty-five patients with AS were recruited to one of three study procedures: WBC at -110°C, -60°C, or exercise therapy (non-WBC). The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score (ASDAS-CRP), concentration of C-reactive protein (CRP), and the concentrations of interleukin 8 and 17 (IL-8, IL-17) were measured at the beginning of the study and at the end of the intervention. The concentration of thiobarbituric acid reactive substances (TBARS), as a lipid peroxidation result, and total antioxidant status, an antioxidant organism potential, were measured. RESULTS: All the studied groups showed significantly decreased posttherapy disease activity expressed as a function of the BASDAI, ASDAS-CRP, and the IL-8 concentration. We found that the TBARS concentration after therapy was significantly increased in the WBC at -110°C group. A comparison of the therapeutic effects between the treatment groups showed a significantly lower BASDAI after therapy in the WBC at -110°C group compared to the non-WBC group. CONCLUSION: WBC at -110°C had a positive effect on lowering AS clinical activity as measured by the BASDAI.

Comparison of prognostic values of cardiopulmonary and heart rate parameters in exercise testing in men with heart failure.

BACKGROUND: Cardiopulmonary exercise testing (CPET) is the gold standard in the evaluation of patients with chronic heart failure (CHF). However, this test is relatively expensive, assessment of its results requires experience, and in Poland it is available only in tertiary health care centers. Many heart rate (HR) parameters taken during a standard electrocardiographic (ECG) exercise test also shows prognostic values. Thus, the aim of this study is to compare prognostic values of ventilatory and HR parameters in exercise testing in CHF patients, and to find out if HR parameters can be used instead of ventilatory in the evaluation of a prognosis. METHODS: One hundred thirty two men (mean age 49 ± 11 years) with CHF with reduced left ventricu-lar ejection fraction (< 45%) underwent a treadmill CPET using a modified Bruce's protocol, during which both HR and ventilatory parameters were measured. The patients were followed for 27 ± 13 months after CPET. RESULTS: Mortality was 28% (n = 37). Non-survivors demonstrated significantly shorter exercise time (342 ± 167 vs. 525 ± 342 s, p < 0.001), lower maximal HR (122 ± 22 vs. 138 ± 21 bpm, p < 0.001), smaller difference between maximal HR and at rest (36 ± 19 vs. 52 ± 21 bpm, p < 0.001), and lower HR recovery rate (HRR; 16 ± 10 vs. 24 ± 13 bpm, p = 0.002), chronotropic index (CHI; 0.45 ± 0.23 vs. 0.61 ± 0.23, p < 0.001), peak oxygen consumption (13.82 ± 4.62 vs. 18.54 ± 5.68 mL/kg/min, p < 0.001) and oxygen uptake efficiency slope (OUES) value (1.56 ± 0.58 vs. 1.94 ± 0.63, p = 0.001), and higher ventilation to carbon dioxide production (VE/VCO2) slope value (40.56 ± 9.11 vs. 33.33 ± 7.36, p < 0.001). Two parameters that showed good prognostic value and availability in a routine CPET were chosen for receiver operating characteristic analysis, VE/VCO2 slope and CHI, which showed cut-off values of 35 (sensitivity 74%, specificity 71%, p < 0.001) and 64 (sensitivity 74%, specificity 68%, p < 0.001) respectively. CONCLUSIONS: Heart rate parameters show significant prognostic values; CHI is the best of them, however, it is weaker than VE/VCO2 slope. HR parameters show somewhat weaker prognostic values in comparison with ventilatory parameters, yet they may be useful in cases of CPET unavailability.

Comparison of Deep Tissue Massage and Therapeutic Massage for Lower Back Pain, Disease Activity, and Functional Capacity of Ankylosing Spondylitis Patients: A Randomized Clinical Pilot Study.

OBJECTIVES: This study aims to compare the effectiveness of deep tissue massage (DTM) and therapeutic massage (TM) in the management of ankylosing spondylitis (AS) patients. MATERIALS AND METHODS: This was a small, randomized clinical pilot study. Subjects were 27 men with diagnosed AS, randomly assigned to DTM group or TM group. Subjects in each group had 10 sessions of massage. Outcomes included the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), Modified Schober Test, Finger to Floor Test, chest expansion, and pain intensity of lower back. RESULTS: There are no statistical significant differences between groups, except for BASDAI and pain intensity of lower back. CONCLUSIONS: This study suggests that massage may have clinical benefits for treating ankylosing spondylitis patients. Additional scientific research in this area is warranted.

Adaptation and Validation of the Foot Function Index-Revised Short Form into Polish.

PURPOSE: The aim of the present study was to adapt the Foot Function Index-Revised Short Form (FFI-RS) questionnaire into Polish and verify its reliability and validity in a group of patients with rheumatoid arthritis (RA). METHODS: The study included 211 patients suffering from RA. The FFI-RS questionnaire underwent standard linguistic adaptation and its psychometric parameters were investigated. The enrolled participants had been recruited for seven months as a convenient sample from the rheumatological hospital in Srem (Poland). They represented different sociodemographic characteristics and were characterized as rural and city environments residents. RESULTS: The mean age of the patients was 58.9 ± 10.2 years. The majority of patients (85%) were female. The average final FFI-RS score was 62.9 ± 15.3. The internal consistency was achieved at a high level of 0.95 in Cronbach's alpha test, with an interclass correlation coefficient ranging between 0.78 and 0.84. A strong correlation was observed between the FFI-RS and Health Assessment Questionnaire-Disability Index (HAQ-DI) questionnaires. CONCLUSION: The Polish version of FFI-RS-PL indicator is an important tool for evaluating the functional condition of patients' feet and can be applied in the diagnosis and treatment of Polish-speaking patients suffering from RA.

Effects of Whole-Body Cryotherapy in Comparison with Other Physical Modalities Used with Kinesitherapy in Rheumatoid Arthritis.

Whole-body cryotherapy (WBC) has been frequently used to supplement the rehabilitation of patients with rheumatoid arthritis (RA). The aim of this study was to compare the effect of WBC and traditional rehabilitation (TR) on clinical parameters and systemic levels of IL-6, TNF-α in patients with RA. The study group comprised 25 patients who were subjected to WBC (-110 °C) and 19 patients who underwent a traditional rehabilitation program. Some clinical variables and levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were used to assess the outcomes. After therapy both groups exhibited similar improvement in pain, disease activity, fatigue, time of walking, and the number of steps over a distance of 50 m. Only significantly better results were observed in HAQ in TR group (p < 0.05). However, similar significant reduction in IL-6 and TNF-α level was observed. The results showed positive effects of a 2-week rehabilitation program for patients with RA regardless of the kind of the applied physical procedure.

Kinesio Taping Does Not Alter Quadriceps Isokinetic Strength and Power in Healthy Nonathletic Men: A Prospective Crossover Study.

OBJECTIVES: The effects of Kinesio Taping (KT) on muscular performance remain largely unclear. This study aimed to investigate the acute effects of KT on the maximum concentric and eccentric quadriceps isokinetic strength. STUDY DESIGN: This is a single-blinded, placebo crossover, repeated measures study. METHODS: Maximum isokinetic concentric/eccentric extension torque, work, and power were assessed by an isokinetic dynamometer without taping (NT) and with KT or placebo taping (PT) in 17 healthy young men. Repeated measures one-way analysis of variance (ANOVA) was used for statistical analyses. RESULTS: Testing concentric contractions at 60°/s or 180°/s isokinetic speed, no significant differences in peak torque (Nm), total work (J), or mean power (W) were noted among the application modes under different conditions. Testing eccentric contractions at 30°/s or 60°/s isokinetic speed, no significant differences in mentioned parameters were noted, respectively. KT on the quadriceps neither decreased nor increased muscle strength in the participants. CONCLUSION: KT application onto the skin overlying the quadriceps muscle does not enhance the strength or power of knee extensors in healthy men.

Effects of different local cryotherapies on systemic levels of TNF-α, IL-6, and clinical parameters in active rheumatoid arthritis.

Cryotherapies are frequently used to supplement the rehabilitation of patients with rheumatoid arthritis (RA) owing to their analgesic and anti-inflammatory effects. Forty patients with active RA were recruited and received 10 days of comprehensive therapy with different local cryotherapies. None of the respondents were subjected to biological treatment. They were divided into two groups according to the therapy received: nitrogen vapour at -160 °C (group I) or cold airflow at -30 °C (group II). Levels of tumour necrosis factor α (TNF-α), interleukin 6 (IL-6), disease activity score (DAS28), and functional variables were used to assess the outcomes. After the therapy, both groups exhibited similar improvements. Significant reduction in TNF-α level (nitrogen: p < 0.01; cold air: p < 0.05) and no change in IL-6 were observed. DAS28, the clinical severity of pain, duration of morning stiffness, degree of self-reported fatigue, and health assessment questionnaire (HAQ) scores improved significantly. In addition, the active range of knee extension, time, and the number of steps in the 50-m walk test also clearly got better in both groups. The 10-day comprehensive therapies including different local cryotherapies for the patients with RA cause significant decrease in TNF-α systemic levels, meaningly improve DAS28, HAQ scores, and some functional parameters, but do not change IL-6 levels. However, there were no differences in the effectiveness of either cryotherapy.
