The extent and pattern of the blood pressure response to the playing of squash was studied in five healthy volunteers using intra-arterial blood pressure recordings. Systolic pressure increased more than diastolic, but by only 18% of basal, peaking 5.2 +/- 2.3 min into the game (mean game duration 49 +/- 4 min). Thereafter there was a progressive decline, with reducing pulse pressure towards basal. There was a marked and significant increase in beat-by-beat blood pressure variability (P less than 0.01) and systolic peaks of up to 200 mmHg were recorded. A peak heart rate of 171 +/- 25 beats min-1 occurred at 20 min. These findings do not support the concept of a disproportionate and prolonged pressor response induced by playing squash. The possibility of high single-beat systolic peaks still justifies some caution in subjects at risk of arterial rupture.
通过动脉内血压记录，对五名健康志愿者进行了研究，以观察打壁球时血压反应的程度和模式。收缩压的升高幅度大于舒张压，但仅比基础值升高18%，在比赛开始5.2±2.3分钟时达到峰值（平均比赛时长49±4分钟）。此后血压逐渐下降，脉压逐渐恢复到基础水平。逐搏血压变异性显著增加（P<0.01），记录到的收缩压峰值高达200mmHg。在20分钟时心率达到峰值，为171±25次/分钟。这些发现不支持打壁球会引发不成比例且持续时间长的升压反应这一观点。然而，由于存在单次收缩压峰值过高的可能性，对于有动脉破裂风险的受试者仍需谨慎。
