The HIMS test, which consists of controlled exercise at increasing workloads, has been developed to monitor changes in training status and accumulative fatigue athletes. As the workload can influence day-to-day variation heart rate, intensity, is associated with highest sensitivity, needs be established goal refining interpretability these rate measurements. aim study was determine within-subject submaximal recovery subjects who reached different intensities. Thirty-eight participated this after familiarization were allocated 1 4 groups based on percentage predicted maximum that elicited during first test (i.e., groups: <85, 85-90, 90-95, >95% rate). Variation determined for following days a range intensities (61-98% rate) periods. decreased intensity all groups. lowest found end last stage 85-90% group (3 +/- bxmin) 2 bxmin). periods occurred minute stage. Although there no significant differences between groups, showed tendency have rate. If are monitored athletes, protocol should elicit 85 90% because least variation.
