Furthermore, impedance cardiography was used to measure maximal heart rate (HR(max)), stroke volume (SV(max)), and cardiac output (CO(max)).
Total exercise time (TET), total work (TW), and maximal power output (W(max)), oxygen uptake (VO(2max)), and pulmonary ventilation (VE(max)) were assessed.
One was the reference (REF) test, whereas the others were performed after the RIP and EIP sessions. Seventeen physically active, healthy male subjects performed three incremental, randomly assigned maximal exercise tests on a cycle ergometer up to exhaustion. The aim of the study was the comparison of standard exercise performances carried out in normal conditions with those carried out following IP, achieved by brief muscle ischemia at rest (RIP) and after exercise (EIP). Moreover, muscle IP has been found capable of improving exercise performance. Ischemic preconditioning of the muscle improves maximal exercise performance but not maximal oxygen uptake in humans.Ĭrisafulli, Antonio Tangianu, Flavio Tocco, Filippo Concu, Alberto Mameli, Ombretta Mulliri, Gabriele Caria, Marcello Aīrief episodes of nonlethal ischemia, commonly known as "ischemic preconditioning" (IP), are protective against cell injury induced by infarction. Following assessment of maximal oxygen intake, all subjects underwent a performance test at the work level which had elicited their maximal oxygen intake. Maximal oxygen intake and associated physiological variables were measured during strenuous exercise on women subjects (N=20 physical education majors).
