These items are very demanding on muscle strength and strength is the basis for speed, so increasing muscle strength is the key to good results. At the same time, due to its short exercise time, mainly in muscle oxygen-free energy-based, so the focus of exercise is the student’s phosphate source (determine the explosive power)
