It is called static streching.
A dynamic stretch is a form of stretching which is beneficial in sports utilizing momentum from form. It is a static-active stretching that propels muscles into an extended range of motion.
Dynamic climbing rope stretches when it is loaded, so for a climber this means that when he falls, the rope will stretch a little as weight is applied, making a fall softer and safer. A static climbing rope does not stretch and has its advantages in situations where you need a rope that does not stretch or give, such as rappelling or caving use. A static rope should not be used by climbers who are lead climbing because taking a fall on a static rope can lead to serious injury to the climber or even cause the rope to snap as it does not properly absorb the force it needs to cushion a fall.
When you hold a stretch for an extended period, then you are performing a static stretch. Dynamic stretching is an active stretching routine that has you slowly moving through motions to increase your heart rate, raise your body temperature and send extra blood to your muscles.
Always warm up before stretching to increase flexibility and prevent injury. Hold each stretch for 15-30 seconds and avoid bouncing, which can cause muscle strain. Stretch both sides of your body evenly to maintain balance and flexibility. Breathe deeply and relax into the stretch, never push yourself to the point of pain.
A moving stretch is commonly referred to as a dynamic stretch. These stretches involve moving parts of your body through a range of motion to enhance flexibility and improve blood circulation before physical activity. Dynamic stretches are recommended for warming up the muscles and preparing the body for exercise.
