(EMG) is a powerful tool in sports biomechanics. It measures electrical activity in muscles during movement, giving insights into muscle activation patterns, timing, and intensity. This data helps optimize athletic performance and prevent injuries.
EMG analysis involves collecting signals from electrodes, processing the data, and interpreting the results. By examining muscle activity timing, intensity, and frequency, researchers can understand technique differences, assess fatigue, and guide training programs for athletes.
