• Skills or Performance Related Physical Fitness

   

  The ability of the neuromuscular system to perform specific tasks
• 1.                      Muscular Strength – refers to the amount of force a muscle or muscle group can exert, also known as isometric strength.
• Muscular endurance- the capacity to exert repetitive muscular force. Endurance of skeletal muscles of the trunk helps maintain correct posture and prevents such problems as low back pain
• Flexibility- the full range movements of a joint, is important to prevent possible injury to ligaments and tendons
• Body composition – refers to the amount of lean versus fat tissues in the body
• ·         Health-related physical fitness is defined as “those aspects of physiological and psychological functioning are believed to offer some protection against generative-type diseases such as coronary heart disease, obesity and various “musculoskeletal disorders”.
• Cardiorespiratory endurance is the level at which your heart, lungs, and muscles work together when you’re exercising for an extended period of time
• Metabolic equivalents (METs) are used to measure your intensity of exercise and uptake of oxygen. They measure energy expenditure at rest.
• Cardiorespiratory endurance is measured by maximum oxygen uptake (VO2 max) and how it’s used during intense exercise.
• Aerobic fitness improves overall health and well-being.
• Strength training improves your muscle and bone health, and helps with weight loss.
• Flexibility allows you to move your body freely
• Your body’s core strength helps stability and balance
• . You can improve stability and balance by doing exercises that focus on the center of your body.
• power Combines speed and strength
• power athletes" are those who exert brute strength in short, all-out efforts,
• Agility is the ability to move quickly and to easily change direction
• Balance itself refers to your ability to adjust your body position to remain upright.
• Reaction time refers to how quickly you can respond to an external stimulus.
• Reaction time hinges heavily on your mind-body connection.
• plays a vital role in building and maintaining strong muscles and bones
• One older study found that 6 weeks of regular exercise reduced feelings of fatigue for 36 people who had reported persistent fatigue
• o    Lack of regular physical activity is a primary cause of chronic disease.
• aerobic exercise may delay or prevent type 2 diabetes.
• Regular moderate intensity physical activity can increase HDL (good) cholesterol while maintaining or offsetting increases in LDL (bad) cholesterol.
• • Hypertension: Participating in regular aerobic exercise can lower resting systolic BP 5–7 mmHG among people with hypertension.

   
• Oxidative stress occurs when the body’s antioxidant defenses cannot completely repair the cell damage caused by compounds known as free radicals
• . Exercise produces endorphins (the “feel good” hormone), which act as a stress reliever and leaves you feeling happy and satisfied.
• Physical activity has been shown to reduce symptoms of depression, anxiety, and stress.
• The American Heart Association recommends that adults engage in at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes per week of vigorous-intensity aerobic activity, or an equivalent combination of both moderate- and vigorous-intensity aerobic activity.
