The purpose of this study was as follows: 1. To determine if the recovery heart rate of ice hockey players is affected by elevation of the legs; 2. To determine the subjective recovery time and to calculate the correlation between subjective and objective recovery times; 3. To determine the heart rate at four and one-half minutes after exercise. Eight of an initial twelve members of the University of British Columbia Varsity Ice Hockey Team, ranging in age from twenty to twenty-seven years, participated in the study. Age, weight, height and position played were obtained for all subjects. Through radio telemetry, in conjunction with an electrocardioscribe and a heart rate monitor, the following data was obtained: a) resting heart rate b) terminal heart rate c) recovery heart rate d) recovery half-time e) post-exercise recovery rate f) subjective recovery time Each subject was required to skate six times: three trials as a control subject, which recovered in normal sitting position, and three times as an experimental subject, which recovered in the recumbent position with the legs raised on a bench twenty inches high. Reliability measurements performed using the Pearson Product-Moment Method resulted in an r = 0.420 for resting heart rates, and an r = 0.649 for terminal heart rates. A correlation between recovery half-times and the subjective recovery times for each of the six trials was calculated. A "t" test for correlated samples was performed between the means of the trials of the control group and between the means of the trials of the experimental group recovery half-times. A "t" test was then performed to determine the significance of the difference between the mean of the means of the recovery half-times of the control and experimental groups. A t value of 2.79, significant at the .05 level of confidence was found. Finally a test of significance was performed on the post-exercise recovery heart rates of the control and experimental groups. On the basis of the statistical analysis and with respect to the small sample studied, the following conclusions appear warranted: 1. Elevation of the legs significantly reduced the recovery time at the .05 level of confidence. 2. The reliabilities of resting and terminal heart rates were too low to be of significant value. 3. The subjects were not able to predict, with any degree of accuracy, when they had recovered sufficiently to begin another skating period. 4. Elevation of the legs and normal sitting produced no significant difference in the heart rates at the end of the four and one-half minute recovery period. / Education, Faculty of / Curriculum and Pedagogy (EDCP), Department of / Graduate
