Abstract

It was widely known that aerobic type of exercise training can increase endurance capacity and decrease blood lactate and epinephrine response to the same absolute exercise intensity. But, little was known about the effect of interval type of anaerobic exercise training on cycling endurance and blood lactate and epinephrine response. Therefore, the main purpose of this study was to evaluate the effect of 6 sessions of anaerobic interval training on endurance capacity and blood lactate and epinephrine response. Eight untrained male college students (22.25±2.49 yrs) were recruited in this study and experienced (1) pre-training endurance test on cycle ergometer, (2) 6 sessions of interval training (1 repetition was consisted of a maximal sprint cycling for 30 seconds and rest for 4 minutes), and (3) post-training endurance test which was the same as pre-training endurance test. Capacity for cycling endurance was tested, and blood lactate and epinephrine were measured pre- and post-training. As a result, sprint type of interval training of 6 sessions significantly increased time for cycling at 80% VO2max (pre-training; 1128.1±147.9 vs. post-training; 1646.6±496.3 seconds, p0.05). There was no significant change in blood lactate and epinephrine in response endurance test in post- compared to pre-training. Therefore, 6 sessions of our sprint type of interval training were enough frequency to improve cycling endurance at 80% VO2max, but did not show typical adaptation patterns of endurance training (e.g., decrease in blood lactate and epinephrine response to the same absolute exercise intensity).
