Describe The Continuous Nature Of The Physical Fitness Concept


By smoking, you are actually introducing carbon monoxide into the body, which is toxic. Tars and other chemicals will settle on the cilia of the lungs and cannot be removed; which further degrades the functionality my house smells of neighbours weed of the respiratory system. Two conditions that develop when a person smokes are emphysema and bronchitis. Balance is the ability to maintain equilibrium by neutralizing the forces that disturb it.

Although established around 100 years ago, our students still use the Harris–Benedict prediction in the physical activity lab. Due to changes in lifestyle, new predictions such as the Mifflin St Jeor equation are more accurate. Flexibility is the ability to move body joints through a full range of motion . By experimenting with your own body, you can immediately tell that joints can be moved to different degrees of motion and that they do not all move in the same way. There are four major joints in the body and each joint because of their limitations move body parts differently. Limitations of ROM in a joint is due to the bony structure holding the joint together and the soft tissue surrounding the particular joint.

Adults should also do muscle-strengthening activities that are moderate or high intensity and involve all major muscle groups on 2 or more days a week, as these activities provide additional health benefits. Modern definition of fitness describe either a person or machine’s ability to perform a specific function or a holistic definition of human adaptability to cope with various situations. This has led to an interrelation of human fitness and attractiveness which has mobilized global fitness and fitness equipment industries. Regarding specific function, fitness is attributed to personnel who possess significant aerobic or anaerobic ability, i.e. strength or endurance. A well rounded fitness program will improve a person in all aspects of fitness, rather than one, such as only cardio/respiratory endurance or only weight training.

The situation is compounded by the number of energy-saving devices Americans use–and the list grows yearly . The amount of energy the average American expended even a decade ago is enormous compared to what we expend in the 1990s. It is easy to worsen slight injuries if a person doesn’t pay attention to soreness or pain. As soon as a person experiences discomfort while exercising, he or she should stop and the injured area should be rested. Time should be taken for the injured area to heal before exercising again.

This is dependent on the concentration of endogenous factors , body temperature, blood flow, hydration status and body position. Physical activity has shown to increase the levels of natural killer cells, NK T cells, macrophages, neutrophils and eosinophils, complements, cytokines, antibodies and T cytotoxic cells. However, the mechanism linking physical activity to immune system is not fully understood.

Ladies performing a common 19th-century fitness routine including climbing the underside of a ladder, balancing and gymnastics. Members of armed forces are often required to pass a formal fitness test.

Among his most important contributions were developing fitness tests for cardiorespiratory endurance, muscular strength, and flexibility. His research resulted in multiple recommendations for the improvement of cardiorespiratory fitness, including the identification of exercise intensity guidelines necessary for improved fitness levels. His suggestions became the fundamental basis behind future exercise programs . Whether the challenge is a London– Brighton cycle race, an ascent of the Matterhorn, or a Channel swim, the fundamentals of this category of fitness are the same. Each of these activities is trained for in essentially the same way — namely, by covering large mileages several days a week for many months, with few if any periods of exertion that are flat out, either in strength or speed.

What this means is that a person with good endurance or stamina can bike, jog, play, or run for a long time without getting tired. Having a healthy endurance level means that a person has a healthy level of cardiovascular fitness. Technically speaking, cardiovascular fitness refers to how efficiently the heart and lungs can pump blood to muscles that are being worked. The more efficiently the heart works, the more energy the body has to continue working without a great deal of effort. Moreover, anxiety and depression reduction after aerobic exercise may be achieved with exercise intensity between 30 and 70% of maximal heart rate .
