BACKGROUND The posterior shoulder muscles play key roles in maintaining shoulder function in throwing. Arm fatigue has been identified as a risk factor for shoulder and elbow pain in youth baseball pitchers. However, endurance of the posterior shoulder muscles in overhead athletes is not routinely examined or conditioned. HYPOTHESIS Upper extremity muscular endurance can be improved in adoles...

AIMS/HYPOTHESIS The aim of this study was to examine the sit up test to exhaustion as a field test for muscular endurance evaluation in a sample of sedentary people of both sexes. METHODS A cross-sectional study was performed. Three-hundred-eighty-one participants volunteered for the study (28.5 ± 10.0 years; 168.2 ± 8.9 cm; 65.1 ± 11.1 kg), of which 194 males (27.5 ± 10.2 years; 173.6 ± 7.0 ...

OBJECTIVES Low back pain is common, costly, and disabling for active duty military personnel and veterans. The evidence is unclear on which management approaches are most effective. The purpose of this study was to assess the effectiveness of lumbar extensor high-intensity progressive resistance exercise (HIPRE) training versus control on improving lumbar extension muscular strength and core mu...

Background Muscular endurance of the trunk is associated with successful performance in athletics, as well as activities of daily living. Furthermore, muscular endurance of the trunk may also play a critical role in injury prevention by allowing individuals to better withstand the effects of repetitive stressors. Pre-exercise, high energy supplements are frequently consumed as a method of impro...

AIM The purpose of this study was to determine whether physical fitness is linked to academic success in middle school students. METHODS The FITNESSGRAM test battery assessed students (n = 838) in the five components of health-related fitness. The Illinois Standardized Achievement Test (ISAT) was used to assess academic achievement in reading and math. RESULTS The largest correlations were ...

PURPOSE To quantify the capillaries in the skeletal muscular tissue of mice with induced peripheral arterial insufficiency, after endurance training. METHOD It was used Wistar mice in 70 days age range, subjected to the total occlusion of right femoral artery. The animals were divided into two groups: sedentary group (SG; n = 05), subjected to activities in the cage; and trained group (TG; n ...

Objective. To examine the effects of a 12-week Hatha yoga intervention on cardiorespiratory endurance, muscular strength and endurance, and flexibility in Chinese adults. Methods. 173 adults (aged 52.0 ± 7.5 years) were assigned to either the yoga intervention group (n = 87) or the waitlist control group (n = 86). 19 dropped out from the study. Primary outcomes were changes in cardiorespiratory...
