Acute Physiological Responses to Isoenergetic High-Intensity Interval Vs. Moderate-Intensity Continuous Exercise in Overweight or Obese Young Females: Focus on Catecholamines, Oxygen Consumption, Lipid Utilization, and Appetite Regulation

What this Trial Is About

This research aims to understand how two types of exercise, Moderate-Intensity Continuous Exercise (MICE) and High-Intensity Interval Exercise (HIIE), affect key body responses linked to fat loss in young women with overweight or obesity. The study focuses on how these exercises impact levels of catecholamines (hormones involved in fat metabolism), oxygen use, fat burning, and appetite regulation. Overweight and obesity are important health issues connected to heart disease, and finding the best exercise approach can help improve weight management and metabolic health. Participants will take part in two different exercise sessions: HIIE involves a warm-up followed by ten one-minute intervals at high intensity alternating with recovery periods, while MICE consists of a warm-up followed by continuous moderate exercise for a longer duration. Both sessions are designed to use the same amount of energy. The study will measure physiological responses during exercise and for two hours afterward. During the study, researchers will collect data on oxygen consumption at rest, during warm-up, exercise, and recovery, along with blood samples to measure catecholamine levels before, during, and after exercise. They will also assess fat and carbohydrate use, as well as appetite and energy intake in the 24 hours following exercise. This detailed monitoring will help clarify how different exercise types influence fat loss mechanisms in this population.
