Datasets of "Effect of knee flexion on muscle oxygen saturation in adults during a 40‐s isometric squat"

The datasets included are the used for the manuscript "Effect of knee flexion on muscle oxygen saturation in adults during a 40‐s isometric squat" (DOI: 10.14814/phy2.70808). This study aimed to evaluate the effect of different knee flexion angles during a 40‐s isometric squat on muscle oxygen saturation (SmO2) responses. Seventeen physically active participants performed three randomized squats at 80°, 90°, and 100° knee angles. Muscle excitation (i.e., RMS) was measured using surface electromyography (EMG), and SmO2 was recorded with near‐infrared spectroscopy technology.
