Why A Warm Up is Needed Before Anything Else
Having a warm-up before the exercise itself starts is something that most people do, maybe without reflecting a lot about how and why you do it. Depending on what type of physical activity you are going to do, and what requirements it imposes on you, the warm-up should be designed accordingly. In some sports, it"s a must to focus on the shoulders, hip, groin, and back. In football, it may be more important with ankle joints, knees, and of course hip and lumps. But, jogging for 3 minutes and doing jumping jacks do not prepare the body optimally.
Why do we need to warm up?
1. Prevent serious damage while performing the activity.
2. Prepare the body to perform as well as possible.
As the body temperature rises, the resistance in muscles and joints reduces, which increases mobility. This is partly because the joint fluid becomes more “hallway" and lubricates the joint (and thus requires less energy to move). An increased temperature in the muscle makes it more elastic, and the risk of tissue breakage decreases. It has been proven in both animals and humans that more power is required to break a warm muscle.
Another reason to warm up is it takes a while for the body to adjust its oxygen absorption capacity while increasing workload. We get something called acne because the muscles do not get the oxygen needed. After a few minutes, as the heart rate increases, oxygen uptake has escaped, and we can use the aerobic energy process. It explains why in the beginning we may feel so heavy and we become breathless, but then comes into something that is commonly called “second breath." If we have started the pulse during the warm up, the body is more prepared for an increased workload.
An increased body temperature may also increase the rate of nerve signals, and may, therefore, have a positive impact on the athletes" ability to react and perform rapid movements.
