what is fitness

Aerobic Exercise
Anaerobic Exercise

1. Aerobic Exercise:

CardioRespiratory Fitness can be measured using vo2 max, a measure of the amount of oxygen the body can uptake and utilize. Aerobic exercise, which improves cardiorespiratory fitness and increase stamina, involves movement that increases the heart rate to improve the body's oxygen consumption. This form of exercise is an important part of all training regiments, whether for professional athletes or for the everyday person.

Examples of Aerobic Exercise:

Jogging, Swimming, Tread mil, Cycling, Walking

2. Anaerobic Exercise:

Anaerobic exercise features high-intensity movements performed in a short period of time. It is a fast, high-intensity exercise that does not require the body to utilize oxygen to produce energy. It helps to promote strength, endurance, speed, and power; and is used by bodybuilders to build workout intensity. Anaerobic exercises are thought to increase the metabolic rate, thereby allowing one to burn additional calories as the body recovers from exercise due to an increase in body temperature and excess post-exercise oxygen consumption after the exercise ended.

Examples of Anaerobic Exercise:

weight training, Isometric exercise, Sprinting, Interval training.

Effects of Exercises:

Controlling blood pressure :

Physical fitness has proven to support the body's blood pressure. Staying active and exercising regularly builds a stronger heart. The heart is the main organ in charge of systolic blood pressure and diastolic blood pressure. Engaging in a physical activity raises blood pressure. Once the subject stops the activity, the blood pressure returns to normal. The more physical activity, the easier this process becomes, resulting in a fitter cardiovascular profile. Through regular physical fitness, it becomes easier to create a rise in blood pressure. This lowers the force on the arteries, and lowers the overall blood pressure.

Cancer prevention :

Centers for disease control and prevention provide lifestyle guidelines for maintaining a balanced diet and engaging in physical activity to reduce the risk of disease. The WCRF/ American Institute for Cancer Research published a list of recommendations that reflect the evidence they have found through consistency in fitness and dietary factors that directly relate to cancer prevention.

Immune system :

Physical activity boosts the immune system. This is dependent on the concentration of endogenous factors, body temperature, blood flow, hydration status and body position. Physical activity has been shown to increase the levels of natural killer (NK) 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.

Weight control :

Achieving resilience through physical fitness promotes a vast and complex range of health-related benefits. Individuals who keep up physical fitness levels generally regulate their distribution of body fat and prevent obesity. Abdominal fat, specifically visceral fat, is most directly affected by engaging in aerobic exercise. Strength training has been known to increase the amount of muscle in the body, however, it can also reduce body fat. Insulin, and appropriate immune, responses are factors that mediate metabolism in relation to abdominal fat. Therefore, physical fitness provides weight control through regulation of these bodily functions.

Physical fitness :

Menopause is often said to have occurred when a woman has had no bleeding for over a year since her last menstrual cycle. There are a number of symptoms connected to menopause, most of which can affect the quality of life of a woman involved in this stage of her life. One way to reduce the severity of the symptoms is to exercise and keep a healthy level of fitness. Prior to and during menopause, as the female body changes, there can be physical, physiological or internal changes to the body. These changes can be reduced or even prevented with regular exercise

Mental health :

Studies have shown that physical activity can improve mental health and well-being. This improvement is due to an increase in blood flow to the brain, allowing for the release of hormones as well as a decrease in stress hormones in the body (e.g., cortisol, adrenaline) while also stimulating the human body's mood boosters and natural painkillers. Not only does exercise release these feel-good hormones, it can also help relieve stress and help build confidence. These trends improve as physical activity is performed on a consistent basis, which makes exercise effective in relieving symptoms of depression and anxiety, positively impacting mental health and bringing about several other benefits.
