The Effect of training for competitive rowing on cardiovascular condition as measured by the brachial pulse wave (Cameron Heartometer) Wallace, Bruce Thomson
The purpose of this study was to examine the effects of training for competitive rowing on cardiovascular condition as measured by the brachial pulse wave (Cameron Heartometer). Brachial pulse wave records were taken on fifteen male subjects (nine varsity and six freshmen rowers) every week over a ten week period. Measurements of fourteen variables were obtained from each individual brachial pulse wave record. The data for each subject consisted of 10 serial measurements for each of 14 brachial pulse wave variables. There were thus 14 variables for each of 15 subjects, giving 210 sets of variables in total. Each of these sets was tested for linearity of regression against number of days elapsed from the beginning of the ten weeks testing period to the time when the pulse wave record was made. As a means of determining relative cardiovascular condition of rowers during training, mean measurements for twelve brachial pulse wave variables of (a) varsity and (b) freshmen crew members were compared with corresponding mean measurements for four non-rowing athletic groups. The brachial pulse wave tracings obtained during the training period suggest that progressive changes in the variables studied were, on the whole, relatively small and unstable. The data suggest that heart rate - blood pressure measurements are fairly sensitive variables in reflecting the effects of training but other measurements of the brachial pulse wave are not. Comparison of the rower's measurements with those of other athletic groups showed that varsity rowers were superior in cardiovascular condition to freshmen rowers before during and after training and that both groups were in many respects superior in cardiovascular condition to other non-rowing athletic groups.
