Reward and Visual Feedback Relative to the Performance and Mechanical Efficiency of High School Girls in the Standing Broad Jump.
Zebas, Carole J.
This study focuses on changes occurring in selected mechanical components of high school girls performing the standing broad jump, and collects data pertaining to the effects of monetary reward and videotape feedback upon the following components: (a) distance jumped, (b) maximum angle of knee flexion, (c) maximum angle of hip flexion, (d) hip extension at takeoff, (e) knee extension at takeoff, (f) linear velocity of the wrist before takeoff, (g) angular velocity of the upper arm, (h) linear velocity of the center of gravity during takeoff, (i) angle of center of gravity at takeoff, and (j) angle of center of gravity at landing. The subjects of the study were 30 high school girls who ranked at or above the 80th percentile in the standing broad jump item of the AAHPER Youth Fitness Test. Each girl was filmed executing the standing broad jump on two separate occasions. On the second try the girls were randomly assigned to one of three groups. One group of 10 girls was treated with the videotape feedback experimental factor, while the second group of 10 girls was treated with a one dollar monetary reward experimental factor. The third group served as a control group. Results indicated that neither a monetary reward nor videotape feedback affects distance jumped or the mechanical efficiency of a performer executing the standing broad jump. (Author/JS)
