Abstract Purpose Examine the mechanical alterations associated with repeated treadmill sprinting performed in HOT (38˚C) and CON (25˚C) conditions.
Methods Eleven recreationally active males performed a 30-min warm-up followed by three sets of five 5-s sprints with 25-s recovery and 3-min between sets in each environment. Constantvelocity running for 1-min at 10 and 20 km.h-1 was also performed prior to and following sprinting.
