How exercise can improve your health and well being.
Health Benefits of Exercise.
Exercise reduces the risk for several diseases including heart disease, adult-onset diabetes, high blood pressure or hypertension, breast cancer, osteoporosis and colon cancer. Exercise may also help prevent, or be effective in treating, some mental illnesses, such as depression. For the greatest overall health benefits, experts recommend that you do 20 to 30 minutes of aerobic activity three or more times a week and some type of muscle strengthening activity and stretching at least twice a week.
Other benefits of exercise.
Exercise controls weight:
Exercise can help prevent excess weight gain or help maintain weight loss. When you engage in physical activity, you burn calories. The more intense the activity, the more calories you burn. You don’t need to set aside large chunks of time for exercise to reap weight-loss benefits
Exercise boosts energy:
Winded by grocery shopping or household chores? Regular physical activity can improve your muscle strength and boost your endurance. Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently. And when your heart and lungs work more efficiently, you have more energy to go about your daily chores
Exercise promotes better sleep:
Many people report having better sleep when they exercise regularly. Typical improvements include falling asleep more quickly, longer periods of deep sleep, and feeling more refreshed in the morning. Because exercise has a positive impact on stress, anxiety, and depression, all of which interfere with sleep, exercise helps improve sleep and reduce emotional health problems.
Exercise improves mood:
Physical activity stimulates various brain chemicals that may leave you feeling happier and more relaxed. You may also feel better about your appearance and yourself when you exercise regularly, which can boost your confidence and improve your self-esteem.
Types of exercise.
Aerobic Training:
A balanced fitness program should include aerobic exercise. Also known as cardiovascular or endurance training, this type of exercise offers benefits such as increased blood flow, boost in HDL, or “good” cholesterol levels, healthy blood pressure and body weight and an overall sense of well-being. There are many aerobic activities from which to choose, including walking, running, swimming, cycling and rowing.
Resistance Training:
While aerobic training offers many health benefits, it does little to tone your muscles. Resistance training, also known as strength or weight training, can reverse the decline in bone density, muscle mass and strength that occurs as you age. It can help you build muscle and burn fat while lowering your risk for heart disease.
Flexibility Training:
Flexibility training, also known as stretching, is an essential component of your fitness regimen. Through stretching, you can reduce muscle cramps, joint stiffness, injuries and stress. Stretching can also help increase your range of motion in your joints and muscles. There are many types of flexibility exercises to keep your interest.
The Importance of Stretching
Stretching is a very effective and important activity that has a number of known key benefits for all. These benefits include improved flexibility, a decrease in the likelihood of injury and muscle soreness, and an enhancement in physical performance.
Through stretching, the affected muscles will be lengthened, which helps to improve the body’s normal level of flexibility as well as to reduce general muscle tension. This increase in muscle length will also enable the muscles to contract over a greater distance and hence create a greater level of power. The body is then able to move more freely with increased comfort.
After physical exercise, the muscles can often feel tight, sore or stiff. Such soreness occurs due to minute tears that form within the muscle fibres, as well as an accumulation of blood and waste products, such as lactic acid. Stretching after exercise, therefore, helps to diminish any muscle soreness through improved blood circulation and the removal of waste products.
Exercise also creates fatigue, and results in a decrease in both mental and physical performance. Stretching muscles can help to prevent fatigue by reducing the pressure on the working muscles. For every muscle, there is an opposing muscle, and if these are made more flexible through stretching then the working muscles have to exert less force against them. The movements of the working muscles will, therefore, require less effort, which will result in the enhancement of an individual’s physical performance.
Additional benefits of regular stretching include improvements in posture, body awareness, energy levels, coordination, and stress relief.
Stretching should be carried out before and after any physical activity, and as part of an individual’s daily routine. A typical stretching routine should last for around 5-10 minutes, with each muscle group being stretched 2 or 3 times. Each stretch should be performed gently and slowly, and held for around 20 seconds only to the point where tension is felt in the muscle. Only stretch muscles that are 100% healthy and avoid areas that are recovering from injury. Stretches should never be performed when the muscles are cold. Prior to any stretching, light, physical activity that results in a light sweat should be performed for about 10 minutes.
