Nutrition and sports: Physical activity increases the energy consumption of the body. For that reason the energy demand on workout days goes up significantly. The exact value is determined by the training intensity and duration. Great loads cause the body to metabolize an extended amount of carbohydrates. It makes sense to increase the food intake respectively on such days. This doesn’t apply for sportsmen and -women who try to achieve weight losses. In this case the food intake shouldn’t necessarily be increased.
Nutrition and sports – increased demand
The protein demand will rise as well no matter whether strength or endurance training is being performed. Special attention needs to be paid to the increased demand of liquids that goes along with that. Intense sports sessions at high heart rates over longer durations (especially in endurance sessions) could cause the body to lose up to 2 liters (for an appr. body weight of 80 kg) of liquids per hour. You have to make sure to supply your body with enough liquids during and after the training. Recommendable would be low-calorie water.
Nutrition and sports – metabolic rate
Nutrition and sports go hand in hand. The basal metabolic rate increases for those who workout regularly and build up their muscles. Muscles consume energy non-stop whereas fat functions as energy accumulator. The higher the proportion of muscles the more calories we will burn when we rest or even sleep. The substitution of fat with muscles is very reasonable from a weight loss point of view.
