Dehydration is one of the biggest threats to peak cycling performanceespecially in hot and humid conditions. But what if you could delay its effects before your ride even begins? Enter hyperhydration: a science-backed strategy designed to increase your bodys fluid reserves before you hit the saddle. By combining sodium, glycerol, or both, hyperhydration can expand plasma volume, reduce core temperature, and extend endurance. Whether you’re training in extreme heat or racing without frequent access to fluids, this technique could be the performance edge youve been missing.We all know the negative impact that being dehydrated can have on performance. If dehydration is bad, then one potential may be to start hyperhydrated to delay dehydration? Here’s a closer look at the science,…

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…
