Essay Preview: Difference Between Physical Activity and Leisure-Time Physical Activity
The difference between Physical activity and Leisure-time physical activity is that one is creates the other. For instance, physical activity is the movement our body creates. It is movement produced by muscles that increases energy expenditure, which includes occupation, household, leisure-time and transportation activities. Leisure-time physical activity is not occupation related, but activity that is planned, such as; sports, hiking, swimming, exercise and resistant training (i.e. recreational activities).
The four components of health benefits of being physically active are: cardiovascular fitness, musculoskeletal fitness, flexibility, and body composition. Building endurance and strength of the heart, lungs, circulatory system, muscles and bones (every living cell in the body) can be maintained by some form are physical activity. By improving physical fitness and performance a person greatly reduces their risk for heart disease, stroke and high blood pressure, developing obesity or type 2 diabetes associated with an increased waist line. Physical activity increase gastric mobility (digestion and eliminated of waist) sooner. This could potentially reduce the risk for developing colon cancer.
Some ergogenic aids include: stretching and weight training (physical aids), visualization, hypnosis, and prayer ( mental/spiritual aids), running shoes or bar bells (mechanical aids) But , the most commonly used ergogenic aid is diet; which includes diet modification like carb loading, diet pills, and other nutritional supplementing.

To meet my energy demands throughout my intensive training I would develop a habit for grazing (5 -6 small meals a day) on energy dense foods. This is very helpful because energy balance creates healthy weight maintenance and the nutrients will support my body requirements during vigorous training.
Lactic acid is a produced by the cells during anaerobic respiration. Lactic acid is not just simply a waste product of anaerobic metabolism. For example, during exercising, the body can not get enough oxygen, when this happens it turns to lactic acid to facilitate energy production. It is important as an energy source during all cellular activity, but aids during exercise to help against fatigue.
