Isokinetic Strength and Anaerobic Capacity

This study aims to investigate differences in isokinetic knee extensor and flexor strength parameters among recreationally active young adult males classified into low, moderate, and high anaerobic power groups based on relative peak power (W/kg) obtained from the Wingate Anaerobic Test. Eighty male participants aged 22-30 years, engaging in regular physical activity, will undergo body composition analysis, isokinetic strength testing at 60°/s, and a 30-second Wingate test performed on separate days. Participants will be grouped according to median-based anaerobic power classification to allow meaningful group comparisons. Group differences in peak torque and total work will be analyzed using ANOVA or non-parametric equivalents, and relationships between Wingate parameters and isokinetic strength will be examined using correlation analyses. The findings are expected to provide novel insights into the relationship between anaerobic power classification and lower-extremity muscle strength profiles, contributing to performance profiling and training planning in recreationally active populations.

Inclusion Criteria: * Male participants aged between 20 and 30 years * Moderately physically active individuals, as defined by the International Physical Activity Questionnaire (IPAQ) * Apparently healthy, with no known neurological, vestibular, or musculoskeletal disorders affecting balance * Ability to stand independently and complete balance assessments * Willingness to participate and provide written informed consent Exclusion Criteria: * History of lower-limb, spine, or pelvic injury or surgery within the past 6 months * Presence of acute or chronic pain affecting posture or balance * Diagnosed neurological, vestibular, or balance disorders * Use of medications or substances that may affect neuromuscular function or postural control * Participation in another clinical or observational study within the past 3 months
