Abstract

Anaerobic capacity has implications in health and sport. Sprint interval training improves anaerobic capacity, aerobic factors, as well as performance performance. Optimal durations for taxing anaerobic capacity have been shown to be 60 seconds, and have been elicited using the Anaerobic Speed Test. In order to maintain this optimal duration for multiple sets, a decreasing workloads method must be used as fatigue increases following each set. These work-loading methods must be compared to determine which protocol allows for the maximum exercise volume to be achieved. The purpose of this study was to compare the effects of three different workload protocols on exercise volume completed during multiple sets of exhaustive anaerobic running on a treadmill. Twelve recreationally active male subjects completed a preliminary session (VO2max test) followed by three sessions of high intensity running on a graded treadmill with three different protocols using parameters adopted from the AST (20% grade, 8 mph to exhaustion). Four sets were completed during each protocol. Protocols included: 1) constant sets (CS): no descending work load in all four sets, 2) descending speed (DS): the speed is decreased by 10% for each subsequent set, 3) descending grade (DG): the grade is decreased by 10% for each subsequent set. Time to exhaustion, work, Stride frequency, heart rate, and RPE were measure for every set. Total work achieved during the four sets of the DS protocol was significantly higher than both the CS (pnd, 3rd and 4th sets of the DS protocol were significantly higher than the 2nd, 3rd and 4th sets of the CS protocol, all under prd set of the DS protocol was significantly lower than the 3rd set of the CS protocol (pth set of the DS protocol was significantly higher than the 4th sets of the CS and DG protocols (p
