The body physiological responses to the exercise paradigms rely on the exercise volume (or pace rate) and exercise duration. During exercise the glycolysis , fat metabolisms and oxygen consumption increase to meet exercise demands that is accompanied with enhanced cardiac and respiratory systems workouts . The body temperature is also dramatically will raise. Depending on the exercise intensity rates ,there are some physical stress on bones and musculature systems 1.

Performing exercises (i.e walking, running ,cycling) in higher level of volume may increase the body stamina and improve the overall fitness. In this relation , several studies showed that vagarious exercises can lead to faster workouts in daily tasks as the body segments and systems depending on the induvial unique capacities can adapt to the different physiological conditions . For example, it has been suggested that executing vigorous exercise is good for disable or elderly populations as it make them to be more active. It is believed that working on higher intensity of their abilities would cause this frail individual to perform more movements over time , although necessary cautions such as the amount of applied exercise intensity are required to take into account at these occasions 23.

Some other evidences recommended that vigorous exercise such as brisk walking can result in some health benefits such as enhancing weight loss, increasing more mechanical stress on muscle and bones to strengthen musculoskeletal system in spite of higher level of muscle soreness 4. Although ,generally not all individual can walk too fast or are able to perform any intensive exercise ,so that performing vagarious exercise cannot be developed to all people as different induvial have non-identical physical abilities in physiologically terms. This is because the tolerated exercise volume (or speed rate) during various mode of exercises is different between induvial .Resultantly ,every person has one unique peak exercise performance capability. Further ,there are some kind of specific people such patients with cardiovascular (CVD) difficulties who are not able to perform exercise in high level of intensities as their health statues can be at more risks at that condition 5. This type of people can manage their health condition with executing moderated kind of exercise modalities (i.e. mild walking at slow pace) to stay healthy with more care. Regular exercise like 10-15 min walking regimen per each day can be beneficial for CVD patients.
