Abstract

The reliability of sport science tools are important where meaningful change is assessed. However, there is little research identifying the reliability of an intermittent high intensity protocol in a hot environment, therefore the purpose of this study was to investigate these factors using a Wattbike Pro. Twelve healthy, males completed three trials, of intermittent sprint protocols (ISP) of: 18 × 4-s maximal sprints in an environmental chamber (35.9 ± 0.7°C, RH 38.0 ± 1.9 %). Each 4-s sprint was followed by 116-s of active recovery.  During each sprint, Power, Heart Rate (HR), thermal comfort and thermal sensation (-3/+3 scales), and RPE were assessed. Peak Average power (highest mean 4s sprint out of 18) 1435W, mean power 1028W, Coefficient of Variation (CV) 3.7 % meaningful change 37W.  Peak power (highest instantaneous power of any 4s sprint) peak power 1556W, mean power 1151W, CV4.1 % meaningful change 46W.  Average power output (mean average power of 18 sprints) peak power 1355W, mean power 938W, CV4.6 % equating to a meaningful change of 40W and also Average Peak (mean of highest instantaneous power of each 18 sprints) peak power 1454W, mean power 1052W, CV3.6 % 36W. This study confirms the reliability of the intermittent high intensity protocol in a hot environment.
