CHARACTERISATION OF THE PHYSIOLOGICAL AND METABOLIC RESPONSES TO DIFFERENT TRAINING STIMULI DURING ARM-CRANK ERGOMETRY
MetadataShow full item record
The purpose of this study was to compare the physiological and metabolic responses to continuous and interval arm crank ergometry (ACE) both during and post exercise. Ten healthy, physically active men (age [mean ± SD], 23.6 ± 3.2years) performed a VO2peak test and subsequently 27-mins ACE at 56% VO2peak with 3-min active recovery at 40% VO2peak and 6, 2-min intervals at 76% VO2peak with 3-min active recovery at 40% VO2peak, all in a counterbalanced order. Baseline measurements were recorded during 5-mins seated rest and recovery data were recorded for up to 1-hr post exercise. Heart rate, RER, VO2, VE and B[La] were recorded throughout the baseline, activity and resting periods, along with RPE during activity, energy expenditure and MET calculated from the physiological data. Blood lactate was significantly different (p ≤ 0.10) throughout continuous and interval exercise and post exercise. No other physiological or metabolic measurements were significant between continuous and interval exercise during exercise and recovery. The findings suggest that continuous and interval ACE elicits similar responses in healthy, male individuals with the exception of B[La], demonstrating that along with continuous exercise, interval training can be used to improve aerobic fitness for those who cannot participate in traditional lower body exercise.
