Fitness is a condition of physical well being and, more importantly, the capacity to do certain aspects of daily activities, jobs and sports. It may be defined as an ability to do things effectively, safely, efficiently, and with minimal exertion. Physical fitness involves several components such as muscular strength, cardiovascular fitness, flexibility, stamina, and endurance. One’s ability to do physical activities is highly influenced by one’s genetic make-up, while environmental factors also play an important role in its development. Fitness may also be improved through the application of certain lifestyle practices and the use of specific fitness equipment. Overall, we assess fitness through various approaches.
Muscle fitness is primarily attained through proper nutrition, balanced calories, regular physical activity, adequate rest, and the repair of tissues that have been damaged by the exertion. The muscle fibers undergo extensive periods of repair after being stretched during physical activity. When the muscle fibers are completely repaired, they are ready for action again. After being stretched, the fibers of the muscle shorten, becoming shorter and stronger. Thus, muscle fiber length and strength directly influence performance during and after physical activity.
Body composition also influences physical fitness. The ideal body composition (body fat percentage less than 17%) and total physical fitness depend on the diet and exercise regime adopted. Although the ideal body composition can be influenced through diet and exercise, the most significant determinant for optimal body composition is the overall flexibility. Individuals with low levels of flexibility are at high risk for disability and have poorer outcomes from rehabilitation efforts.
Fitness is further categorized into three major categories: walking, running, swimming, or resistance training. Each of these forms of fitness requires specific motor skills: balancing the body, walking, jumping, and sprinting. In addition, each of these exercises requires specific muscle groups to be worked out: the muscles used in walking need to be strong to enable you to move across the earth; swimming requires the muscles in your arms and legs to overcome the resistance of the water; and running requires both flexibility and cardiovascular capacity. Thus, the development of specific motor and coordination skills is an important criterion in determining an individual’s level of fitness. The development of flexibility, however, is not a primary factor related to fitness.
The third factor affecting physical fitness and staying active is an individual’s ability to adapt to any form of stress. The ability of the mind to change while staying active is perhaps the most important determinant. Being mentally stable is the key to staying active and healthy. Many studies show that people who are extremely mentally stable are able to withstand extreme mental stresses. These individuals are better able to cope with health challenges. A healthy mind is the key to staying active and healthy.
Fitness is affected by many aspects, such as the body composition of an individual, overall health, flexibility, muscle strength, and so on. These factors affect one another, affecting an individual’s level of fitness as they progress through their physical fitness training program. There are many examples would include body composition, age, and gender. These examples would help readers understand how fitness varies among individuals. In conclusion, fitness and staying active are interrelated, requiring different approaches to achieve goals in different ways.
