Effetti dell’estrazione del calore sulla fatica percepita negli atleti amatoriali

This study investigated the effects of using the CoolMitt device, which allows heat to be extrapolated from the palm of the hand via a closed-loop cooling system. The protocol used included two sessions: the first time to determine maximum aerobic speed (MAV) while the second time involved determining maximum hand strength and a High Intensity Interval Training (HIIT) training. The population of amateur athletes (age: 26± 5 years) was divided into an experimental group, which during passive recovery of HIIT training used the working device and a control group that inserted the hands into the device at thermo-neutral temperature. The results show a significant reduction in Rating of Perceived Exertion (RPE) values in the experimental group as well as significantly lower maximum RPE values. Furthermore, an increase compared to pre- and post-training handgrip values was detected in the experimental group. This evidence demonstrates how heat extraction from the palm of the hand can represent a favorable method for reducing RPE and improving performance in isometric force work.
