Background The aim of this study was to estimate the bone mass (BM)and bone mineral density (BMD) of the non-dominate forearm and compare these measurements to basic features of somatic structure and habitual physical activity (PA) levels in adult men. Material and methods The study examined 160 men aged 20 to 50, randomly sampled from Warsaw, Poland. Bone mineral density and BM of the forearm was measured with dual energy x-ray absorptiometry. Anthropometric measurements included: height, body mass, and the width of the elbow and wrist of the non-dominant limb. Habitual PA was assessed by the International Physical Activity Questionnaire. Results The men with sufficient to high levels of PA demonstrated normal values for the T-score in the both the distal and proximal forearm measurement sites in more than 90% of participants and more than 50% in the those with sufficient level of PA. In the group with insufficient levels of PA, low values of the T - score indicating osteopenia was found in both the proximal and distal measurement sites, 71% and 80% respectively. Significant, though weak positive correlations were found between BMD, an indicator of T – score, and a both elbow and wrist widths. Conclusions Lack of PA is clearly associated with an increased occurrence of osteopenia and osteoporosis in men. This study supports the notion that osteopenia and osteoporosis is present in younger adult men and that sufficient habitual PA is a important factor to preserve bone health.

Introduction Obesity is associated with increased risk of chronic diseases. An increasing of physical activity can prevent the obesity and improve the daily life quality in older adults. The purpose of this study was to investigate the effect of modified Thai Yoga on metabolic intensity and energy expenditure in obese older adult Thai women. Material and methods Twenty-six participants, aged 56-75 years old, were divided into two groups: non-obese group (NB) and obese group (OB) defined by their body mass index. After 12 sessions of familiarization, the participants performed the modified Thai Yoga exercise program for 60 minutes. Energy expenditure and metabolic variables were measured via open circuit calorimetry. Results At the exercise phase, the mean percentage of maximum heart rate for the OB and NB groups were OB: 57.43±6.32 % and 59.89±7.94%, respectively. The mean oxygen consumption for the OB group was 7.52±1.09 ml/min/kg as compared to the NB group which was 8.44±0.90 ml/min/kg. The mean metabolic equivalent (MET) for the OB group was 2.15±0.31 MET as compared to 2.41±0.26 MET for the NB group. Total energy expenditure for the OB and NB groups were 3531.32±483.47 kcal/day and 3090.82±387.99 kcal/day, respectively. The mean of activity energy expenditure for the OB group was 1509.65±498.72 kcal/day and 1393.39±367.41 kcal/day for the NB group. The difference between all parameters measured from OB and NB groups were significant (p<0.05). Conclusions These results demonstrated that this modified Thai Yoga program provides a well-tolerated light intensity exercise stimulus and could be prescribed as an exercise program for obese older adults.

Purpose. The aim of this study was to evaluate the associations between anaerobic performance (AnP), applicable field tests, and the functional classification levels in female wheelchair basketball athletes. Methods. Female wheelchair basketball athletes (N = 23; Category A, n = 9; Category B, n = 14) from the Canadian national team were evaluated using field tests and the 30-second Wingate Anaerobic Test. Measures of peak power output (PP), time to achieve peak power (tPP), mean power output (MP), and a fatigue index (FI) were used to assess AnP. A test battery evaluating seven wheelchair basketball skills was applied. Student’s t test was used to identify differences between the two main functional categories (A and B). Spearman’s rank correlation coefficient and Pearson’s product-moment correlation coefficient were calculated to determine the significance of all relationships between the parameters of AnP, the results of the field tests, and the eight functional classification levels of the athletes (1.0-4.5 pts.). Results. In all analyzed parameters, except for the field test measuring shooting skills, the results of AnP were significantly higher for Category B players. Significant relationships were observed between athletes’ classification level and AnP and the field tests except for tPP, the 5 m sprint, and the shooting test. The strongest association was observed for MP and PP, MP and FI, PP and FI (p = 0.001). Conclusions. Strong associations were found between the functional classification level and AnP of the female wheelchair basketball athletes. The strongest correlation was confirmed between MP, PP, and the field test measuring the two-handed chest pass, suggesting that this test can be used to indirectly assess the anaerobic performance of female wheelchair basketball athletes.
