Twenty healthy young adults aged 18 to 35 years underwent various tests and measurements related to hip abduction and adduction strength, neuromuscular activation, muscle thickness via ultrasound imaging, and physical performance tests such as the Four Square Step Test (FSST) and the two-legged side hop test. Measures included maximal voluntary isometric contractions, surface electromyography (EMG) recordings, and ultrasound image acquisition. Statistical analyses involved Pearson's correlations and multiple regression analysis.
