Document Summary
In the discussion on back health there is some overlap with the anatomy and back strength exercises discussed in unit 6: discuss the arguments for and against including static stretching in a warm-up routine. For: decreases risk of injury by increasing flexibility prior to activity. Increasing flexibility allows for greater rom for athletic performance. Increased stretchability causes tissues to rupture more easily. 1: no effect on activities where muscle length is not a factor. Explain why each exercise is considered to be potentially harmful. Single or double leg inverted hurdler"s stretch: results in over stretching tissues, crushing, pinching nerves and jamming joints in knee, hurdler stretch, the bent knee will be over stretched. Tissue and nerve damage: describe two flexibility/warm-up exercises that are considered to be potentially dangerous to the lower back. Explain why each exercise is considered to be potentially harmful: pinch nerve fibres in back, squeezes spinal discs.
