The purpose of this study was to examine the effects of fatigue on force application and resulting movement patterns during the performance of consecutive chin-ups. Special attention was directed toward relating any fatigue effects to upper limb strength dominance. Twenty male adult subjects each performed one trial. Each trial consisted of consecutive chin-ups. Fatigue caused changes in the movement patterns, duration of movement and force applied through the supporting hands. Throughout the performance greater vertical forces were applied through the dominant upper limb segment with the application of these forces resulting in horizontal displacement of the total body center of gravity toward the dominant hand.

The performance of Uneven Parallel Bar skills by junior high girls is hindered by blister formation on the hands. The problem was to investigate certain measures relative to their value in blister prevention.

The purpose of this study was to compare the effects of six- and twelve-second time intervals of eccentric strength training among college males. Thirty-eight students were used in two experimental groups and one control group. Subjects in the two experimental groups trained three days a week for seven consecutive weeks and were required to perform two sets -of eccentric exercise with three repetitions in each set for either six- or twelve-second intervals, depending upon the experimental group assignment. Results indicated that there was a significant differ ence between the experimental groups' mean strength gain and that of the control group. There was no significant difference between the two experimental groups.

The present investigation was designed to examine the effects of the positive manipulation of information on self-efficacy and subsequent performance of 180 female subjects. High, moderate, and low self-efficacy subjects were randomly assigned to a treatment condition in a 3 x 4 x 3 (preexisting self-efficacy x efficacy information source x trials) factorial design. Information from the three efficacy sources of performance accomplishments, verbal persuasion, and vicarious experience was manipulated towards success after subjects completed a muscular leg endurance task. The results supported self-efficacy theory with high self-efficacy subjects extending their legs significantly longer than moderate and low self-efficacy subjects. However, subjects did not differentially [sic] respond to the manipulation of the efficacy information. Results are discussed in terms of efficacy as a mediator of performance on an endurance task as well as the lack of differential changes in efficacy based on the source from which that information is derived.

The purpose of the investigation was to determine the interrelationships of strength, speed, power and anthropometric measures in women. Sixty females ranging in ages from 18 to 25 volunteered as subjects. Subjects were measured for strength on the bench press, leg extension and leg curl, power vertical jump, speed--a 40 yard dash, body weight (BW) and fat weight (FW) using a scale and skinfold tests. The correlations for strength and power (.35 to .53), strength and speed (-.37 to -.56) and speed and power (-.45) were significant (p < .01). Partial correlations with (BW) and (FW) held constant were also significant, but were not significantly greater than their zero-order correlations.
