How Does High Intensity Interval Exercise Affect Fat Loss?, Melissa Grohman
How Does High Intensity Interval Exercise Affect Fat Loss?, Melissa Grohman
The Science Journal of the Lander College of Arts and Sciences
US survey trends show that since the 1970’s there has been a decline in energy intake, (consumption of food) and a rise in the prevalence of obesity. This suggests that there must have been a dramatic decrease in total energy expenditure. Energy expenditure is the sum of energy (or calories) the body needs to carry out physical functions such as breathing and digestion, as well as the energy used in physical activity. As the rate of obesity in the US increases, it is becoming more and more important to find ways to increase energy expenditure, specifically through physical activity. Physical …

The purpose of this paper is to investigate the adaptations that occur in human skeletal muscle in response to endurance and resistance exercises. The advances made in science over the past several decades increased the number of methods available for the classification of muscle fibers, resulting in many fiber type classes and their corresponding characteristics. This allows for the tracking of changes that occur within the muscle fibers. The heterogeneous collection of fiber types found within a muscle allows for its dynamic nature. Myosin form expression varies according to the muscle’s changing functional demands. In response to endurance training, muscle …
