Obesity and excessive body fat are a serious problem in today's society. Sedentary lifestyle, inappropriate diet and not enough activity are just some of the factors, which contribute to the increasing number of overweight and obese people. Since obesity has been growing steadily for several decades, we decided to compare three different methods of exercising and their impact on the loss of body fat in this diploma thesis. We compared the method of continuous steady state effort, high-intensity interval training, and weight training.
We are talking about obesity and overweight when the excess body fat is so large that it could have an adverse health effect. The most common measures to determine obesity are the body mass index (BMI) and body fat percentage measurement. Obesity is one of the main causes of cardiovascular diseases, it causes diabetes, osteoarthritis, and even some types of cancer. During physical activity or exercise, the flow of blood through the fat and muscle tissue increases, resulting in the release of several fatty acids from the fat tissue to the bloodstream, which the muscle can use for energy.
The goal of the diploma thesis was to determine how and to what extent each type of exercise affects fat loss, to describe all the advantages and disadvantages of each type, to compare them with each other and to determine which method or combination of methods is most effective for fat loss. According to the findings, high-intensity interval training (HIIT) is the most effective method for fat loss, since for similar results, in terms of burning fat, this method requires less time exercising than the method of continuous effort. Due to the high intensity, HIIT may be unsuitable for beginners, which is why the method of continuous effort is also suitable for fat loss. Weight training has the least impact on fat loss of the methods listed, but it is very important in terms of keeping the lean muscle mass, as it can maintain a high level of resting metabolic rate despite the weight loss.
