Predictors of physical fitness in a college sample.

The present study examined the relationships among self-reported amounts of exercise, body composition, age, weight, blood pressure, and physical fitness. Participants reported their duration and frequency of exercise, which were combined to obtain individual indexes of exercise. VO2 max predicted from a 1-mi.

The effects of three modalities on delayed onset muscle soreness.

Delayed onset muscle soreness is a common problem that can interfere with rehabilitation as well as activities of daily living. The purpose of this study was to test the impact of therapeutic massage, upper body ergometry, or microcurrent electrical stimulation on muscle soreness and force deficits evident following a high-intensity eccentric exercise bout. Forty untrained, volunteer female subjects were randomly assigned to one of three treatment groups or to a control group.

Cardiovascular responses to arm cranking and FNS-induced leg exercise in paraplegics.

Twelve spinal cord-injured males performed arm-crank exercise (ACE) with and without concurrent functional neuromuscular stimulation (FNS) of paralyzed leg muscles to investigate the hypothesis that FNS would augment cardiovascular performance during submaximal ACE. Six men who exhibited vigorous isometric contractions of thigh and calf muscles were classed as "responders" to FNS (R), and the remaining subjects with poor or nonexistent contractions served as "nonresponder controls" (C). Steady-state heart rate and oxygen uptake during ACE at 30, 60, and 90 W were not appreciably different from the ACE + FNS condition.
