The bike allows long-term efforts at an intensity which corresponds very well to a maximum oxidation of fats.
Bike and weight loss: there are few studies
Traditionally, the bike has enough little inspired researchers for the benefit of the foot race when it comes to assessing the impact on overweight and weight loss. It must be said that the calculation of energy expenditure is relatively simple as regards the race: a calorie is spent per kilo of body weight for each kilometer travelled. You can also specify that a lot of researchers are also runners assiduous!
Against the weight, the teenagers on the bike
in 2009, a team of researchers Tunisians has derogated from this habit and conducted a study on three groups of adolescents in overweight (42% of fat mass). The age is important!
The surveys show that most obesity is formed early, more it short of risk of developing traditional diseases related to overweight: diabetes, cardiovascular disease, osteoarthritis, cancer.
The study in question was to prescribe meetings to bike to the first group of 18 subjects and to compare the loss of weight with that of a second group (always 18) subject to a restricted diet severe (500 calories less than usual). A third of same importance associated with the regime and the bike.
It should be noted also that the drive consisted of four weekly sessions of an hour and a half of bike at moderate intensity. The study lasted two months (a total of 32 meetings per person or 48 hours of saddle).
The group loser is not the one you believe
outcome of races: the 18 subjects of the first group (the one of the drive only) have only lost two pounds in two months. This is significantly less than those of the second group (scheme only) who have lost 5 kilos on average.
Without surprise, the best scores were achieved by the association bike/regime with a weight loss of 6.2 kilograms.
If we look at the figures, one might conclude to a low influence of sport in terms of weight loss. But the authors are not content to observe the weight curve, they have also paid attention to changes in body composition.
They have realized that all the young people who had followed the sports program had won the muscle to the thighs and calves. On average, they were increased from 46.4 to 47.1 kilos of lean body mass.
The weight on the balance therefore reflects badly enough the evolution of body composition.
In fact, the young people of the first group had lost three kilos of fat and gained a kilo of muscle. However, the muscle is a fabric very costly on the energy plan. For little that they maintain this muscle mass by the adoption of the bicycle as a mode of daily transportation, they will have the guarantee that it will retain a metabolism of higher base which will contribute to the guide on the path to an ideal weight.
