The biceps curl test is easy to apply, does not require expensive equipment, and its short execution time makes it feasible in school settings with limited resources. To verify the reliability of children adolescents provide reference values according chronological age sex. A total 1103 schoolchildren aged 6 17 years (500 boys 603 girls) were evaluated. Weight height evaluated Body Mass Index (BMI) Tri Ponderal (TPI) calculated. right left hand was 30 s. Children 11 used a 1 kg dumbbell those 12 2 dumbbell. Percentiles calculated using LMS method. relative Technical Error Measurement (TEM%) both hands ranged from 0.48 2.89%. intraclass correlation coefficient (ICC) evidenced high 0.93 0.99. Bland-Altman plot showed wide limits agreement (-1.28 1.29 rep). These findings demonstrate that reliable consistent for use pediatric populations suitable different stages physical development children. stability agreement. In addition, proposed percentiles are useful evaluate monitor strength endurance performance arms.

The purpose of this study was to examine the impact listening classical music on functional (upper and lower body strength, mobility aerobic endurance) cognitive (attentional capacities working memory (WM)) performances in women aged between 50 60 years old. A total 24 middle-aged were enrolled participate study. Their assessed under two-auditory conditions (no-music vs. with conditions) using Timed Up Go (TUG) test for mobility, Arm Curl 30 s Chair Stand Tests upper respectively, 2 min Step endurance. To assess attentional WM, a simple reaction time (SRT) Corsi Block-Tapping Task used, respectively. As result, we found that significantly decreased scores TUG (p < 0.001) 0.05), increased values compared no-music condition. However, no significant changes strength WM. We conclude music, i.e., Mozart’s Symphony, is effective improving endurance women. these gains absent muscle suggesting positive effects dependent specific task.

To verify the reliability of biceps curl test in children and adolescents to provide reference values according chronological age sex. A total 1103 schoolchildren aged 6 17 years (500 boys 603 girls) were evaluated. Weight height evaluated Body Mass Index (BMI) Tri Ponderal (TPI) calculated. The right left hand was 30 seconds. Children 11 used a 1 kg dumbbell those 12 2 dumbbell. Percentiles calculated using LMS method. relative Technical Error Measurement (TEM%) both hands ranged from 0.48 2.89%. intraclass correlation coefficient (ICC) evidenced high 0.93 0.99. Bland-Altman plot showed wide limits agreement (-1.28 1.29 rep). It verified that is reliable evaluate strength endurance adolescents. stability agreement. In addition, proposed percentiles are useful monitor performance arms.
