High intensity exercise may be an efficient startegy for obesity management

INTERVENTION: At the start of the study, participants undergo two sessions of preliminary testing after an overnight fast to determine athropometric measurements, phsyiological measures (lung capacity and blood pressure) and metabolic testing. Once the participants completed preliminary testing, they complete a total of 18 training sessions (three sessions per week for six weeks). Each of the prescribed sessions begins with a 5‐minute warm‐up of continuous cycling at moderate intensity (40% of their individual VO2peak power) followed by 6 repetitions of SET intervals with 2 minutes of passive recovery between each repetition. Each SET repetition lasts for six seconds, and the participants are asked to pedal at maximal velocity against the resistance determined during day three. The total duration of each session is approximately 15 minutes. The training sessions are conducted under the supervision of a member of the research team, and velocities (in RPM) were recorded for each second of the bout to ensure that fixed velocities remained constant. Post‐intervention metabolic and blood pressure measurements are conducted 24‐hours, 72‐hours and two‐weeks after the final training session to obtain information on the potential lasting effects of SET. The post‐intervention anthropometric assessment is performed 24 hours after the final SET session, and the post‐intervention exercise tests are performed 72 hours after the final SET session. CONDITION: Obesity ; Nutritional, Metabolic, Endocrine ; Obesity PRIMARY OUTCOME: Insulin resistance (HOMA‐IR) is determined by measuring blood glucose and insulin concentrations at baseline, 24 hours, 72 hours and 2 weeks post‐intervention. SECONDARY OUTCOME: 1. BMI is calculated as the ratio of mass (kg) to height squared (m2) at baseline and 24 hours post‐intervention; 2. Maximal oxygen consumption (VO2max) is measured using an incremental maximal test at baseline and 72 hours post‐intervention; 3. Maximal power is measured using a force‐velocity test on a cycle ergometer at baseline and 72 hours post‐intervention; 4. Blood pressure is measured using an automated blood pressure monitor at baseline, 72 hours and 2 weeks post‐intervention INCLUSION CRITERIA: 1. Aged between 18 an 30 years 2. Obesity (BMI >30 kg/m2) 3. Sedentary (<1 h/week of structured exercise)
