Coppell Fitness Trainer Tip of the week

Working out in warmer temperatures may increase how many calories your body is able to burn.
There are not a lot of studies out there but as this summer is getting VERY HOT, we have to give you some type of motivation (other than it just so fun) to come out and workout with us in 100 degree temperature.

Most of you know that hot yoga has not only helped people increase their fitness levels and flexibility but it has helped folks lose weight. The warmer temperature causes the body to work harder (hint – hint – burn more calories) to adapt to the change in temperature.

In one study, nine male subjects cycled for 90 minutes in different temperatures: -10 degrees Celsius, zero degrees Celsius, 10 degrees Celsius and 20 degrees Celsius. During the two colder temperatures, there was a higher respiratory exchange ratio indicating that more carbohydrate was used for fuel and less fat was oxidized than during the warmer trials (1). In another study of eight male cyclists, subjects rode to exhaustion in four different temperatures (approximately 4, 10, 20 and 30 degrees Celsius). The longest time to exhaustion was found at 10 degrees Celsius and the shortest was at 30 degrees Celsius. This research showed a relationship between temperature and exercise capacity with the best exercise able to be performed in the moderate ranges with the lowest capacity on either end of the temperature extremes. (2) These two studies suggest that working out in moderate to warm temperature is best for burning fat and exercising longer, so more calories are burned overall.
