Heated Training Vs. Performance

Whether you're a competitive athlete or a very motivated recreational one, you're always trying to push past previous plateaus. Setting a new personal best is a reward in itself. However, environmental heat stress has been known to degrade aerobic performance. The effect was measured in a study published in the journal Medicine & Science in Sports & Exercise.

Scientists had subjects cycle for 30 minutes at 50% of their capacity. Then they performed 15-minute time trials in moderate and hot environments. When compared to what they did in moderate temperatures, the cyclist's effort decreased 17% in a hotter environment.

The Bigger Picture: While most residents of the northern latitudes don't have to worry about excessive heat when working outside during the winter months, if you go to one of those gyms that cranks up the heat to tropical rainforest conditions on really cold days, don't push too hard and make sure to stay hydrated with plenty of fluids while training. Hydration's important even if your workout environment is downright cold.

Number two is an absolute myth. Rigidly ctrlnooled metabolic ward studies have debunked this. The idea came from TEF concept, but given isocaloric conditions, the TEF does not differ between 3 meals and 6 meals. The metabolic fire nonsense needs to go.
