Background. A new index achieved from exercise test is the systolic blood pressure index obtained during recovery of stress test (systolic blood pressure at 1st and 3rd minute of recovery/maximal systolic blood pressure). The alteration (increasing) of the systolic blood index can individuate patients with ischaemic heart disease and those subjects with tendency to hypertensive disease. The goal of our study was to evaluate the systolic blood pressure indices of agonistic athletes. Materials and methods. We considered 116 medium level athletes (men) of various sports (cyclists 53, footballers 29, runners 33, tennis-players 7, others 14). We considered also 51 age-matched sedentary men without diseases as control group. Athletes and controls underwent bicycle ergometry stress test and we calculated systolic blood pressure indices at 1st and 3rd minute of recovery. Results. In athletes we measured a systolic blood pressure index higher than that of sedentary people at 1st minute of recovery (0.85+/-0.087 vs 0.81+/-0.07) but at 3rd minute the differences were not significative (0.69+/-0.072 vs 0.07+/-0.08). We didn't find differences of blood systolic pressure index among the athletes of different sports in this study. An alterated blood pressure index (higher 0.93) was found in 17 athletes (14.6%) at 1st minute of recovery and only in one case this was alterated at 3rd minute (higher than 0.84). Conclusions. Blood systolic pressure index at 1st minute of bicycle ergometry stress test recovery is higher in athletes than in sedentary subjects. This could be related to cardiovascular adaptions produced by training. Blood systolic pressure index at 3rd minute of recovery is the same between athletes and sedentary subjects. Blood systolic pressure index can individualize cardiovascular disease. Blood systolic pressure index could represent a good screening index during examination for agonistic sport fitness.
