Abstract

High Intensity interval Training (HIIT) in running prescription can be applied in a variety of different ways, but HIIT prescription lacks specificity and efficiency in determining what duration of interval is optimal for improved aerobic performance. The purpose of this study was to test different HIIT protocols with a 1:1 ratio active: recovery intervals of 2:2 minute (Protocol 1), 4:4 minute (Protocol 2) and a continuous run trial (CRT). Seven recreational male runners (Age= 23.1 ± 3.4 yr, Height= 1.80 ± 0.1, Weight= 75.8 ± 9.6) performed a maximal oxygen consumption test (60.5 ± 4.9 ml/kg/min) with a graded exercise test. Their VO2max scores were then converted to their running speed by using the ACSM metabolic running equation. Protocols 1 and 2 were HIIT running protocols, and Protocol 3 was a continuous running trial (CRT), all protocols had the same average intensity (85% VO2max). A one way repeated measures ANOVA was used to determine the differences between all running protocols on time to exhaustion (volitional fatigue), and Protocol 2 elicited the shortest time to exhaustion, followed by Protocol 1 and then the CRT was the longest in duration. Recreational runners can use this studies finding to improve their VO2max, anaerobic/ aerobic energy systems, and HIIT implementation.
