  8. Components of fitness 1) Cardiorespiratory • To improve, you must overload! • Aerobic vs Anaerobic • Frequency • Intensity • Calculate Target heart rate (THR) • THR = X% (MHR) • http://www.online-stopwatch.com/large-online-clock/ • THR = 0.6 (220-40) = 108 • THR = 0.8 (220-40) = 144 • Time • Type

  9. Components of fitness 2) Muscular fitness • Muscular strength • Muscular endurance • Improving muscular fitness – overloading • Frequency • Intensity • Time • Type • Breathing • Muscles need oxygen!

  10. Components of fitness 3) Flexibility • Determinants of flexibility • Improving flexibility by stretching • Static • Passive • Ballistic

  11. Benefits of stretching and Flexibility • Injury prevention • Relief of muscle strain • Relaxation • Relief of muscle soreness • Improved posture

  12. Components of fitness 4) Body composition • Relative amounts of fat and fat-free mass of body • Recommended % body fat • Women: 21 – 35% • Men: 8 – 24%
