Exercises: What Are The Different Kinds?
1. Stretches, Range of Motion — These movements are done slowly and gently, because they are intended to increase flexibility of the body, the muscles and ligaments. With gradual motion, one’s muscle can lengthen as you relax into a stretch, and the connective tissues can become accustomed to stretching by slowly changing position — widening the angle at which a joint is flexed, and so on. Range of motion is useful to maintain the ability to move all parts of the body and, as with all exercises, to enhance circulation.
2. Aerobic Exercise — This type of exercise can be done for longer periods of time than Resistance exercise, because it is less intense on the muscles. It includes jogging, jumping and many other lighter activities. It burns fat by using oxygen (and indeed, we think of aerobics as those that make us need to breathe deeply and quickly, pulling in as much oxygen as we can) in large amounts.
3. Resistance, or Strength Training — Resistance is muscle-building exercise. While aerobics build muscle somewhat, the greater intensity of muscle contractions involved in resistance are necessary to developing muscles and making them denser, stronger. Weightlifting and sprinting are both examples of resistance exercises. This type cannot be done for long periods of time, as they are more difficult for muscles to perform.
All three kinds of exercise are necessary for a healthy body. Each workout should have at least 2 — some stretches, and then either aerobics or strengthening. Ending a workout with some easy stretching can help avoid muscle soreness.
What are –
Isometrics: Strongly contract or tighten the muscles of your arm without bending or moving your arm, and that is isometric exercise. As if they’ve gone out of style, you don’t hear about this type very often anymore. But they are important and useful exercises to do when you during air travel or other periods when you are confined to sitting or standing for a long time without much elbow room. Doing some isometric tightening and relaxing of your arms, legs, and glutes can help pump your blood and get rid of that sluggish soreness.
Concentric vs. Eccentric contracting of the muscles: Sometimes, you’ll see weightlifters assist one another when they do bicep curls with weights. The one working out with the weight will do half the lift, just lowering the weight as he straightens his arm. His training partner then lifts his arm back up, the hand with the weight going towards the shoulder; and then the first man lowers it again. He is focusing on the eccentric, or lengthening motion of the exercise. Lifting the weight as he curls his arm is the concentric motion, or shortening contraction, of the bicep muscle. Some training in both muscle movements can help protect against injury.
