Even here in Canada, eventually hot summer weather will come. One strategy popular with athletes for reducing heat stress before or during competitions are ice vests. How effective are they?For endurance sports, the evidence is clear and unequivocal that performance is impaired with higher ambient temperatures. Its also reduced in cold temperatures or with a drop in core temperature. Data generally points to an inverted-U relationship, where performance is optimal at a moderate temperature, but becomes progressively reduced above or below this optimal range.This optimal temperature might be lower than we think, with a classic study from my post-doc lab at U Aberdeen finding that cycling tolerance time at a constant hard effort was longest at 11C, similarly reduced at…
