Summary

Accurate normalization of peak torque (PT) is critical for comparing muscle strength across individuals of varying body composition. While body weight (BW) is commonly used, body mass index (BMI) may provide a more stable representation of inter-individual variability. The study aims to compare the effects of BW and BMI normalization on inter-individual variability of trunk, hip, and knee muscle strength in healthy female participants.

Detailed description

Accurate normalization of peak torque (PT) is critical for comparing muscle strength across individuals of varying body composition. While body weight (BW) is commonly used, body mass index (BMI) may provide a more stable representation of inter-individual variability. The study aims to compare the effects of BW and BMI normalization on inter-individual variability of trunk, hip, and knee muscle strength in healthy female participants. Thirty healthy adult females will undergo isokinetic testing of trunk flexors/extensors, hip flexors/extensors/abductors/adductors, and knee flexors/extensors. PT values will be normalized to BW and BMI. Coefficient of variation (CV%) will be calculated for each method to evaluate relative variability.
