Summary

This study looks at how a single session of walking or cycling changes certain proteins in the blood that are linked to autophagy—the body's way of cleaning out damaged cells. Forty healthy men aged 18-35 will walk or cycle, and researchers will measure three autophagy-related proteins before and after exercise. The goal is to learn more about how different types of exercise affect cell health without needing invasive muscle biopsies.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

A total of 20 healthy male volunteers aged between 18 and 35 years, who engage in physical activity at least 2-3 days per week for a minimum of 30 minutes and have no known health problems, will be included in the study. To avoid the effects of previous medical conditions, individuals with acute or chronic injuries in the bilateral/unilateral lower extremities, musculoskeletal disorders, or a history of surgical intervention to the hip and/or knee joints will be excluded from the study. Participants will be instructed to minimize all sports activities 48 hours prior to the assessment days; however, normal daily activities such as walking and stair climbing will be permitted. In addition, participants will be advised to maintain their usual daily routines and to consume the same types of food on the assessment days.
