Wearing a Cooling Jacket During Exercise Reduces Thermal Strain and Improves Endurance Exercise Performance in a Warm Environment

Effects of pre-cooling procedures on intermittent-sprint exercise performance in warm conditions

“…Moreover, while minimal differences were evident between conditions for distance covered in jogging and walking, respectively, the total distance covered for all sub-maximal bouts shows that the combined ice-bath and vest cooling procedure increased the distance covered by~300-400-m compared to control or ice-bath only. Thus, while pre-cooling procedures may have limited influence on intermittent-sprint performance, pre-cooling is potentially effective in improving the sub-maximal work of team-sport athletes in hot conditions, similar to data previously reported for endurance exercise (Booth et al 1997;Arngrímsson et al 2004;Hasegawa et al 2005).…”

“…As such, methods such as cold baths, cold ambient air and ice vests have been utilised to varying effect to delay the rise in T core during prolonged duration repeated sprint efforts (Marino 2002). These procedures have improved endurance performance in exercise protocols consisting of constantload exercise to fatigue (Lee and Haymes 1995;Hasegawa et al 2005), total maximal work performed in a set time (Booth et al 1997) and time to complete variable-paced efforts of set distance (Arngrímsson et al 2004). However, minimal performance benefits have been reported by the small number of studies investigating pre-cooling and intermittent-sprint exercise (simulating team-sport activity) (Drust et al 2000;Duffield et al 2003;Cheung and Robinson 2004).…”

Effect of a Cooling Vest on Core Temperature in Athletes With and Without Spinal Cord Injury

“…This could be a result of the vest precluding evaporative cooling (evaporation of sweat), lack of control for exercise intensity in all groups, peripheral vasoconstriction in the skin due to the cold vest temperature (though less likely), or lack of precooling with the vest as done in the studies by Hasegawa and Chou that reported positive results. 23,28,49,50 Despite the lack of objective evidence for efficacy of the cooling vest on T c , 3 of the 5 SCI athletes who responded to the mail survey reported feeling subjectively cooler with the vest. Although we do not have the information on the level of injury of each respondent (anonymous survey), one explanation is that persons with paraplegia have more intact chest skin sensation resulting in ascending afferent input of the conductive cooling.…”

Thermoregulation in elite athletes

“…Cooling vests worn during the precompetition warm-up enhance time to exhaustion during constant-rate exercise [37,38] and improve performance during self-paced trials that simulate competitive events [39]. Similarly, application of ice packs to the lower limbs resulting in both local and general changes in body temperature improved sprint performance during 40 min of intermittent exercise in the heat (348C) [35].…”
