Introduction: To examine palm cooling’s (15°C) impact, subjects performed 3 four-set leg press workouts in a randomized sequence.
Methods: Per workout they received 1 of 3 treatments: no palm cooling, palm cooling between sets, or palm cooling between sets and post-exercise. Dependent variables were examined with three-way ANOVAs; average power underwent a three-way ANCOVA with body fat percentage as the covariate.
Results: Simple effects analysis was our post hoc and α=0.05. Left hand skin temperatures produced a two-way interaction (no palm cooling, palm cooling between sets>palm cooling between sets and post-exercise at several time points). A “high responder” subset had their data analyzed with an additional three-way ANOVA that again produced a two-way interaction (palm cooling between sets>no palm cooling>palm cooling between sets and post-exercise at multiple time points). Blood lactate results included a two-way interaction (no palm cooling>palm cooling between sets, palm cooling between sets and post-exercise at 0 min post-exercise). Average power yielded a two-way interaction (palm cooling between sets, palm cooling between sets>no palm cooling for the fourth set).
Conclusions: Intermittent palm cooling hastened heat removal and blood lactate clearance, as well as delayed average power decrements.

In Simple Terms:
This study tested if cooling the palms with 15°C gloves during and after leg workouts could help people perform better. When participants used palm cooling between sets, they kept their power up longer and had less lactic acid right after exercising. The cooling also helped their bodies get rid of heat faster. Overall, palm cooling between sets helped delay fatigue and improve workout performance.
