Research studies have shown an overwhelming evidence of the physiological and biochemical impact physical exercise has on the body. A sedentary lifestyle has been found to be a silent killer, being one of the ten leading causes of death and disability. Listed below are scientifically proven health benefits that are reaped from regular physical activity.
Scientifically-Proven Health Benefits Of Exercise
 Weight Management
Reaching and maintaining a healthy weight is achieved by regular physical activity. Exercise offsets a caloric overload when more calories are consumed in a day than actually required. It increases the rate of energy use, boosts your metabolism and as a result, helps control body weight.
 Cardiovascular Health
Regular exercise boosts good cholesterol (HDL – High Density Lipoprotein) and decreases bad cholesterol (LDL – Low Density Lipoprotein), improving blood flow and increasing the working capacity of the heart. It thus helps lower blood pressure, strengthens the heart, helps prevent or treat high blood pressure as well as heart disease.
 Prevention And Control Of Diabetes
Exercise, in conjunction with weight loss and healthy diet help reduce the risk of developing type-2 diabetes (non-insulin dependent diabetes). Secondly, diabetics who perform regular exercises lower the risk of developing complications associated with diabetes, and tend to have a lower mortality rate than diabetics with sedentary lifestyles. Doing endurance exercise prior to having meals, lowers blood sugar more than performing the same exercise after meals. Insulin function is improved as the muscles’ demand for glucose is increased.
 Brain Function
Studies have shown that there is a correlation between higher levels of exercise and a reduced risk of cognitive decline and dementia. Physical activity stimulates chemical substances in the brain which support the region responsible for memory and learning. Cognitive function is thus enhanced, helping to reduce the risk of brain degeneration.
 Depression And Stress
Regular exercise has been found to promote mental health improve self-confidence boost self-esteem increase motivation help reduce stress and the symptoms of depression Levels of endorphin and serotonin are elevated during and even several days after exercising, contributing largely to improvement in mood. Endorphins have long been known to have analgesic (pain-relieving) and anti-depressant effect in the body.
 Immune System
Moderate exercise has a positive impact on the human immune system. Studies show a decreased incidence of upper respiratory tract infection (URTI) in people who performed moderate exercise.
 Muscle Mass And Strength
Exercise has a profound impact on muscle mass, strength, endurance, coordination and balance. Muscles are highly responsive to strength training, rendering them stronger, larger and reducing the risk of injury.
 Bone Density And Joint Mobility
Bone responds to exercise by becoming stronger. People who are physically active tend to achieve greater peak bone mass than those who have a sedentary lifestyle. Aging comes with bone loss, however, regular exercise can contribute to the delay or prevention of this loss. It can therefore protect one against osteoporosis and the risk of bone fractures.
Regular physical activity improves one’s physical performance by enhancing their range of motion. Joints are kept active and flexible, helping them make better movements. The surrounding muscles also tend to become stronger to support these joint movements.
Be motivated, regular physical activity is a master key you should be holding. Crank that engine up well before it gets cranky with age!
