The Science behind palm cooling

Ergogenic
Ergogenic tools help Athletes increase capacity for bodily or mental labor especially by eliminating fatigue symptoms.
Caffeine is the perfect example of a well-known ergogenic aid. Intended to enhance physical performance, stamina, or recovery.
​Recent discoveries in sport science are showing ergogenic effects of cooling specific parts of the body during aerobic and resistive training.

The Known Ergogenic Response to Palm Cooling
Participants that used intermittent palm cooling experienced:​​
-
Lower core body temperatures.
-
lower heart rates
-
Lower rate of perceived exertion
​​
Palm cooling while endurance testing in males and females results in higher total exercise volume and higher repetitions for resistive exercises.​
​​
Leading Theories
Thermoregulation
By controlling the bodies core temperature muscles are able to stay cool and this thermoregulation via palm cooling enables more endurance and power from the muscles during resistance and aerobic training.
​
Transient Receptor Potential Channels (TRPs)
By stimulating specialized heat sensing cells in the hands, the central nervous system alters perceived pain inadvertently blocking or delaying the sensation of fatigue.
