Forty-five subjects were given 30 trials of isometric elbow flexion
and 30 trials of elbow extension. Each trial consisted of maximum
exertion followed by a short rest in 10 second cycles. Subjects were
ranked on the basis of the addition of the median flexion and extension
scores and were divided...
Forty-eight young adult males were ranked on the basis of mean
hand-grip strength scores and the middle one-third, the medium
strength range, were chosen as subjects. These sixteen subjects were
given 30 serial trials in each of four tests; knee flexion, knee
extension, elbow flexion, and elbow extension. Each trial...
The ability to quickly generate torque of the triple extensors is critical during rapid movements, especially when there is not enough time to reach peak torque. Rate of torque development (RTD), which is the rate of rise of the torque-time curve, is a commonly used measure of rapid torque generation....
Purpose: The purpose of this study was to determine the effectiveness, if any, of ten weeks of motor psychophysics training on the
development of dynamic muscular strength (as measured by the bench
press and squat) in male college athletes and non-athletes.
Procedures: This study was conducted during the first (spring)...
The purpose of this investigation was to determine the
effectiveness of a 6-week strength training program consisting of
squat and plyometric exercises on vertical power jump performance,
static and dynamic muscular strength, and muscular power production
in college age adults. Fifteen male and two female college students
in an advanced...
The first goal of this study was to understand the role of calpains in skeletal muscle
protein degradation in cultured cells. We have developed a genetic approach to inhibit
endogenous calpain activity through over-expressing dominant negative m-calpain (DN),
antisense m-calpain (AS) and calpastatin inhibitory domain (CID). We observed that,
under...
Objective: To determine the effectiveness of moderate pre-exercise warm-up, static stretching, or a combination of both on muscular force production and hamstring extensibility of the lower extremity. Design and Setting: This experiment was a counterbalanced repeated measures design of four treatment conditions. Subjects participated in warm-up, static stretching, combined warm-up...
