The study will cover 40 men, players of amateur football leagues, aged 18 - 40. The test will include the measurement of sEMG of the biceps and gluteal muscles during the exercise, followed by myofascial self-release (SMR). Muscle sEMG was re-measured immediately after roller therapy.
The aim of the study is to assess the impact of SMR intervention in the hamstring muscles on the activity of the biceps and gluteus muscles.
