Most protocols for testing and rehabilitation for recovery and improve-ment of muscular endurance have been set at 180°/sec, 240°/sec, and 300°/sec. These protocols can cause confusion to clinical providers or other researchers. This study was aimed at investigating the optimal isokinetic angular speed for measuring or developing muscular endur-ance after assessing the relationship between cardiopulmonary re-sponses and isokinetic moments. This study was conducted with 31 male and female college students. Graded exercise test and body com-position were measured as well as the isokinetic moments of the knee muscles at three angular speeds: 180°/sec, 240°/sec, and 300°/sec. The specific isokinetic moments of knee muscles that were measured in-cluded: peak torque (PT) and total work (TW) on extensor (e) and flexor (f) of knee joints, which were denoted as ePT180, fPT180, eTW180, fTW180, ePT240, fPT240, eTW240, fTW240, ePT300, fPT300, eTW300, and fTW300 according to the three angular speeds. Spearman correla-tion test was used to examine the relationship between the sum means of cardiopulmonary responses and the variables of isokinetic moments. This study confirmed that the optimal angular speed for testing or train-ing for muscular endurance was 180°/sec, which showed a stronger relationship between cardiopulmonary responses and isokinetic mo-ments. Therefore, this angular speed is recommended for testing and training for muscular endurance of the knee joints.
