Abstract

Subjects (n = 34) did three rowing workouts of up to eight 2- minute stages separated by 45-60 second rests. Cardiovascular, ergogenic, thermoregulatory, perceptual and metabolic responses to workouts may be aided by intermittent palm cooling. Subjects received one of the following treatments per workout in a randomized sequence: no palm cooling, intermittent palm cooling during workouts, or palm cooling applied intermittently during workouts and post-exercise recovery. Methods: Palm cooling entailed intermittent cold (8-11o C) against the palmar surface of subject’s hands. Workouts began with 10 minutes of rest, followed by a 10-minute low- intensity warm-up and the workout, concluding with a 20-minute post-exercise recovery period. Work volume was examined with a two-way ANOVA with repeated measures for workout. All other variables were each examined with three-way (gender, workout, time) ANOVAs. Results: Palm cooling elicited significant effects on decreasing HR and BP. A trend for work volume differences exist as follows: NoPC < PCex, PCex&post. [BLa-] saw a significant time effect. RPE results yielded non-significant differences.
