Dynamic vs. static exercise
Dynamic exercise activities keep joints and muscles moving. It increases heart rate which then promotes better blood circulation throughout the body, strengthens muscle, and enhances endurance. However, dynamic exercises present problem of changing, irregular demands on strength throughout the motion, and critical moments where the movement cannot stop without losing control over the weight. If control is lost, severe injuries may result; besides the possibility of crushing the body, joints and tissue can be torn. As well, the irregular strength demands can hide flaws (through shifts in balance) and can cause uneven development of muscle groups, which adds to the danger over time.
Static exercise, also known as isometrics, it involves it exerts muscles at high intensities without movement of the joints. Pushing on a heavy couch that does not move is an example of static exercise. Static exercise improves strength, but it also drives up blood pressure in an instant. People with circulation problems and high blood pressure should avoid exerting pressure without muscle movement. Danger in isometric exercise is primarily attributed to its immediate effects on the rapid rise of pressure on the blood. One performed with poor breath control, may result in fainting, stroke, or other injury.
Both relates to the physical activities involving fitness. Stretching may be categorized as static or dynamic. How it is done would determine it, stretching is good for the body. Especially when starting your aerobic activity, it should not cause pain, stretching should be done at least 30 seconds to keep it safe. When doing any of the two activities its best to consult a trainer to get a best results and at the same time be on the safe. If you have health issues, it is best to consult a doctor before starting any activities
