This article will give you a short introduction to the aspects of basic exercise and why do we need it.We've all heard people say exercise is a great option to reduce weight or to stay healthier.Many also claim that not only does exercise help them stay fit physically but it also helps in maintaining the mental health.Today there is an increasing emphasis onpreventive medicine, or maintaining health, partly as a result of the increasing costs of health care and our greater awareness of the effects of lifestyle on our own health.We are conscious of the foods that are harmful for us and the food that is healthier, yet some are having the desire to eat the food that might harm one's health.Only way is to avoid those foods the other is to do exercise regularly.But doing both is the obvious option since eating fatty items and exercising hard to reduce weight or stay healthier ,will get you nowhere.
Also, it has been found that exercise helps your body to utilize the oxygen you breath to be used effectively.Studies have shown that athletes(regular exercisers) have a very low percentage of oxygen wastage.i.e. they utilize almost all the oxygen they breath in.But an average man, who is not fit physically is prone to utilize below 80% of oxygen that he breaths in.Hence we are more prone to the oxidative effects(cause for ageing)if we don't have regular physical exercise.
Our body supplies energy to us for all the physical activities through metabolism, where the body glucose is burned to release energy.Some of you who have in some point of your life gone to a gym would have heard these terms-Aerobic and anaerobic exercise.The metabolism of glycogen or glucose that we talked about earlier,to provide energy for exercise occurs in one of two ways, depending on the presence of available oxygen to the muscle, which in turn depends on the type of exercise being performed. If oxygen is not available -this is called anaerobic activity, glycogen or glucose will be broken down by the anaerobic pathway.
