Abstract
The heart rate response to squash during a normal game was studied for 75 subjects. Twenty‐ five were included in each of three groups, namely, middle‐aged sedentary, middle‐aged active and “A” grade squash players. Heart rates were recorded by means of radiotelemetry in order to evaluate the intensity of exertion during the playing period. The middle‐aged sedentary group was found to have significantly higher heart rates than both the middle‐aged active and the “A” grade groups, while no significant difference was registered in a comparison of the last two categories. These results were statistically significant at the 0‐01 level of confidence, which was maintained throughout the entire study. No interaction was found between the groups during the 25 minutes of play and the heart rate means for every time slot remained in the same order from highest to lowest for middle‐aged sedentary, “A” grade and middle‐aged active groups respectively. This study indicates that squash is a vigorous activity which could be dangerous when played by middle‐aged sedentary males.
