Physical Fitness What components make up Physical Fitness What are the benefits of Fitness How hard do you need to train to become Fit
What are the components of Physical Fitness Muscular Strength/power – the ability to move a resistance Flexibility – the range of motion around a joint Muscular Endurance – the ability to do repetitive exercise without fatigue Cardio Vascular endurance – the ability to supply oxygen to the muscles during aerobic exercise Body Composition – body shape and the % body fat you carry
Flexibility – the range of motion around a joint • Improved flexibility helps in better skill performance and in prevention of injury during activity
Muscular endurance – ability to do repetitive exercise without fatigue
Cardio Vascular Endurance – ability to supply oxygen to the muscle during activity • Also known as Aerobic Fitness. Aerobic means with Oxygen
Body Types and Composition Ectomorph – thin, slender Mesomorph – broad shoulder, narrow waist Endomorph – pear shaped We are born with a body type or shape. We can do things to tone or change our weight but we cannot change our basic body shape
Body Composition • Everyone carries body fat. The Norms for males in their late teens is: • Males = 14 to 18% body fat • Females = 18 to 22% body fat • Body fat is stored energy Reserve. • Calories that are not metabolized (burned for energy) are stored in adipose cells as fat. Adipose cells are found under the skin all over the body but in men the largest deposit is around the stomach and women around the thighs and hips
Body Fat Uses • Body fat is stored energy and can be used for energy when our primary source of energy from carbohydrates is depleted. • Body fat helps keep the body insulated and warm in cold temperatures. • A small amount of Body fat is essential in metabolizing food during digestion
Body Fat Disadvantages • Adds extra weight to our frame, placing increased demands on our muscles , heart/lungs and energy system during exercise. • The increased girth around our limbs can impede our movements making it harder to perform daily tasks or sports activities. • The extra weight puts added strain on our joints and can increase risk of arthritis or chronic tendon/ligament inflamation. • Excess fat in our circulatory system can lead to increased risks of coronary heart disease and strokes.
Body Mass Index or BMI • BMI can also be used to approximate your body fat composition • BMI uses your height and weight in a formula to give an approximation of your body fat fitness level. The formula is BMI = Weight/Height X Height • There are differences between men and women • Also muscle is heavier than fat and can cause inaccuracies
What are the benefits of Physical Fitness Vitality – full of energy and endurance Improved self image Improved health and immune system Improved confidence in ability to perform Improved brain function (alert, focus, learning)
