The authors investigated the effect of chronic exercise on feelings of energy and fatigue using meta-analytic techniques. Chronic exercise increased feelings of energy and lessened feelings of fatigue compared with control conditions by a mean effect delta of 0.37. The effect varied according to the presence or absence of a placebo control or…

This study examined the progressive effects of performing a fatiguing task on the static strength of two muscle groups involved in the performance of the task. (Author/JA)

The book provides a practical and meaningful treatment program for athletes involved in sports which injure the arm or shoulder to a high degree, such as tennis, baseball, swimming, raquetball, pole vaulting, javelin throwing, and weight training. The book's chapters present information on: (1) symptoms of injury; (2) the anatomy of injury; (3)…

Utilization of ice and exercise conjunctively decreases recovery time of muscle tendon injury considerably. In the healing process, collagen (a major element of scar formation) is laid down. If heat and rest are used as treatment, healing takes place; however, collagen is laid down in a haphazard arrangement increasing the likelihood of reinjury.…

This document describes activities in an aquatic program designed for an individual in sound health. Instructions for performing each activity are given in step-by-step outline form.
