Activation of Antagonist Knee Muscles During Isokinetic Efforts in Prepubertal and Adult Males
The deficit of muscle-force production observed in children can be partly attributed to neural factors, such as an increased level of coactivation. This hypothesis, however, has not been thoroughly investigated under concentric and eccentric isokinetic conditions at different angular velocities. Thus, the purpose of this study was to examine whether prepubescent children present higher levels o...
متن کاملPrevalence of Gardnerella vaginalis in prepubertal males.
OBJECTIVES To determine the rate of occurrence of Gardnerella vaginalis in the genital tract and rectum of the asymptomatic prepubertal boy and to examine the effect of circumcision on the rate of recovery. DESIGN A prospective survey design was used. Cultures for G vaginalis were obtained from the urethral meatus, surrounding glans, and rectum of prepubertal boys. Boys who had a history of s...
متن کاملCaffeine ingestion and isokinetic strength.
The purpose of this study was to investigate the effects of caffeine on maximum voluntary contractions of the dominant knee extension and flexion muscles in 12 male intercollegiate track sprinters. Caffeine (5 mg.kg-1) and placebo (225 mg methylcellulose) gelatin capsules were administered orally in randomly assigned order. Muscle function was measured isokinetically by a Cybex II dynamometer i...
متن کاملReliability of a single-session isokinetic and isometric strength measurement protocol in older men.
BACKGROUND The purposes of the current study were (a) to determine the test-retest reliability of a single-session isokinetic and isometric strength testing protocol in older healthy men, and (b) to compare the outcomes of the reliability measures derived from averaged torque scores with those derived from a single peak torque score. METHODS In 19 men (mean age, 72 +/- 5 years), both lower li...
متن کاملPrepubertal Impact of Protein Intake and Physical Activity on Weight-Bearing Peak Bone Mass and Strength in Males.
Context Peak bone mass (PBM) and strength are important determinants of fracture risk in later life. During growth, bone is responsive to changes in nutrition and physical activity (PA), particularly before pubertal maturation. Objective In prepubertal healthy boys, protein intake (Prot-Int) enhances the impact of PA on weight-bearing bone. We hypothesized that the synergism between Prot-Int ...
