A Comparative Analysis of Selected Mechanical Aspects of the Ice Skating Stride.
Marino, G. Wayne
This study quantitatively analyzes selected aspects of the skating strides of above-average and below-average ability skaters. Subproblems were to determine how stride length and stride rate are affected by changes in skating velocity, to ascertain whether the basic assumption that stride length accurately approximates horizontal movement of the center of gravity during each stride is valid, and to identify some of the fundamental differences in skating stride between above- and below-average performers. Groups of five skaters performing at three different velocities were filmed. Each subject performed three trials at each of a maximum and two submaximal speeds. Graphic and statistical analyses were used to determine performance trends and the statistical significance of differences in performance parameters. Analysis of the data revealed that stride rate increased as a function of horizontal velocity for both levels of performers. No apparent trends were found for stride length in relation to velocity. Above-average skaters exhibited higher stride rates, longer stride lengths, and longer glide phases than did skaters of below-average ability. Also, above-average performers displayed less flexion of the lower leg, and, consequently, vertical displacement of the foot was less during the recovery phase of the ice skating stride. (Author)
