COMPONENTS OF FITNESS Health and Skill Related...
COMPONENTS OF FITNESS • 5 Health-Related Fitness Components Brainstorm these in groups of 3-4 • 6 Skill-Related Fitness Components
COMPONENTS OF FITNESS • 5 Health-Related Fitness Components • Cardio-Respiratory Endurance • Muscular Strength • Muscular Endurance • Body Composition • Flexibility • 6 Skill-Related Fitness Components • Agility • Muscular Power • Speed • Balance • Coordination • Reaction Time
A very simplistic approach to Health-Related fitness components. • Cardio-Respiratory fitness, sometimes called endurance or stamina, refers to the heart’s ability to pump blood and the blood vessels’ ability to carry blood to the muscle cells in order to process oxygen and carry away waste products. Because oxygen is used during endurance-type activity, cardio-vascular fitness is also referred to as ‘aerobic’. • Changes in your heart, blood vessels and lungs take place when you start incorporating endurance-type activity in your exercise programme. The lungs, where the blood picks up oxygen, become more efficient. As a result, your heart becomes stronger, pumping more blood more efficiently with each beat. You end up pumping more blood with fewer beats per minute.
A very simplistic approach to Health-Related fitness components. • Muscular Strength is the ability of a muscle to exert force and overcome resistance. It is the maximum amount of force the muscle can exert in one contraction. • Muscular Endurance is the ability of the muscles or groups of muscles to keep going in an activity or movement. Put simply, with adequate strength you can perform an activity for a short time, but muscular endurance lets you continue for longer. Muscular strength is needed to stand up, muscular endurance is what keeps you standing for awhile.
A very simplistic approach to Health-Related fitness components. • Flexibility is the ability to use a muscle to its full extent and increases the range of movement around a joint. Flexible muscles help you move your joints; to bend, stretch, and twist easily and safely. Maintaining good joint movement reduces the risk of injury and soreness, particularly as you get older. • Body Compositionrelates to the percentage of body weight that is fat compared to other body tissue ie. muscle/bone. Exercise helps you develop muscle tissue instead of fat tissue. • Fat control is important for preventing disorders as fat people have increased risk for hypokinetic disease eg. heart disease. • ‘Overfat’: more body fat than you should have. • ‘Overweight’: weigh more than someone your age and size. • ‘Obese’: very overfat.
A very simplistic approach to Health-Related fitness components. • The Body Mass Index (BMI) is a calculation used to measure body composition. It is a simple means of rating body weight relative to height. • Weight(kg) ÷ (Height metres)² = BMI e.g. 98 ÷ (1.88 x 1.88) = = 98 ÷ 3.5344 = 27.72 (BMI) Less than 25kg/m² GOOD 25 – 30 kg/m² OVERWEIGHT Above 30kg/m² OBESE
