Importance of indoor activities in physical education

I believe that the school should have a one-year physical education course in our school for all the students because it can be beneficial. Having a physical education course can help the student maintain in shape and strength. Some indoor activities for the students that I think they should do is jogging, running, cycling, dancing, swimming, climbing stairs, stretching, sit-ups, push-ups, leg lifts, squats, weight lifting.

Jogging, running, cycling, dancing, climbing stairs and swimming is all part of aerobic activities, which are exercises that work your heart and lungs and improve your ability to take in oxygen. Certain activity make you breathe faster and make your heart beat faster. These activities enable you to take in more air and therefore oxygen, which is supplied to the muscles. These activities make the heart more efficient. Aerobic exercise uses oxygen to keep large muscle groups moving continuously at an intensity that can be maintained for at least 20 minutes. Aerobic exercise uses several major muscle groups throughout the body, resulting in greater demands on the cardiovascular and respiratory systems to supply oxygen to the working muscles.

Stretching exercises consists of neck roll, should roll, wrist roll, toe-touch stretch, should pull, etc. stretching has many advantages such as reducing muscle tension and making the whole body feel supple. Other advantages are that it increases range of movements in the joints; prevents injuries; helps to prepare for the desired activity like running, swimming, cycling, etc.; increases the temperature of the muscles, which optimizes their performance; increases the circulation of the blood to various parts of the body; and enhances muscular co-ordination.

During anaerobic metabolism, the breakdown of glucose stops at an early point, producing lactic acid and two molecules of ATP. This anaerobic metabolism produces a so-called oxygen debt, which is repaid later when oxygen becomes available. When a skeletal muscle is heavily worked, the acute soreness that results is due partly to a buildup of lactic acid. The presence of lactic acid can also be felt during exercise as a burning sensation in the muscles. Sit-ups, push-ups, leg lifts, squats, and weight lifting are all part of anaerobic exercises. Anaerobic exercise involves heavy work by a limited number of muscles. Anaerobic activities can build muscle power. This gives you the strength to carry, push or pull things. The stronger your muscles are, the more force you can exert. Muscular strength helps you to prevent injuries and reduce low back pain. It improves posture and overall ability in sports. You can also do physical work with less fatigue. Weight lifting and other types of anaerobic exercise increase strength and muscle mass, but are of limited benefit to cardiovascular health. Other anaerobic activities can be leg kick, sitting crunch, sanding push-up, chair dip, etc.

The benefits of these activities is that it results in better coordination of muscles, and an increase in strength, flexibility and stamina. While improvements in these areas certainly help athletic performance, they also help reduce the risk of injury: Stronger, limber muscles are less susceptible to strain and sprain. Aerobic and strengthening exercises can result is weight loss when combined with a calorie-reducing diet. Without exercise, dieting can cause the loss of muscle as well as fat. An aerobic exercise regimen burns fat, while building muscle. This may mean less dramatic weight loss, but since muscle tissue burns more calories than fat tissue, the result is longer lasting. Consistent, regular exercise actually strengthens the heart, resulting in more blood and oxygen flow throughout the body. At the same time, aerobic exercise lowers blood pressure and cholesterol levels, both major health risks for many Americans. Poor posture is a major cause of injury, and often leads to big problems later in life. Exercising in proper form promotes better posture, as well as the strengthening and stretching of muscles that help you stand up straight.

A fitness regimen offers many psychological benefits, but the biggest payoff comes from an improved self image. Achieving fitness goals leads to self confidence, improved body image, self awareness and esteem. Athletes often recount the first time they surpassed what they believed the limit of their skills, and how this affected their opinions of themselves. In addition, the discipline necessary to accomplish personal fitness goals can have a positive effect on your professional career.
