However, the benefits appear to be due to decreased cardiovascular strain and
thermoregulatory strain increased substrate availability resulting in an increased time before a limiting work rate is attained, which may not be relevant for precision, non-aerobic sports such as shooting. Factors that may impair shooting
performance in the heat are; reductions in cognitive ability and decreased comfort affecting a shooter’s well
rehearsed routines, vasodilation causing swelling in the hand modifying the hand grip on the pistol, increases in physiological
tremor and increases in ballistocardiac tremor from an increased heart rate tremor It has however been found previously
that pre-cooling the forearm prior to shooting decreases the incidence of tremor and enhances
performance
