1. PRINCIPLES OF AEROBIC EXERCISE

2. Lecture objective By the end of this lecture student will be able to understand about: Difference B/W aerobics & anaerobic exercises Goals of aerobic exercises general concepts about aerobic exercises

3. Aerobic exercises Aerobic exercises: is the ability to exercise or compete for a long time without getting breathless .

4. ANAEROBIC FITNESS ANAEROBIC FITNESS is the ability to work at a high intensity for a short period of time The repayment comes in the form of gasping breaths at the end of activity. This is to enable as much oxygen as possible to get back into the respiratory system and to eliminate as much of the waste product as possible .

5. GENERAL CONCEPT OF AEROBICS What exercises will you do to get strength Calves Quadriceps Hamstrings Gluteals Chest Latissimus & Rhomboid major

6. Goals of Anaerobic Training Strength Hypertrophy Power development Rehabilitation Neuromuscular control Anaerobic metabolism

7. Anaerobic adaptations Beginning in the higher brain centers Corticospinal tract Organization of motor patterns Synchronization of motor units

8. Anaerobic adaptations Neuromuscular junctions Larger surface areas More neurotransmitter receptor Motor nerves Activation thresholds Frequency of firing

9. Anaerobic adaptations Continuing down to the level of individual muscle fibers Spindle sensitivity Hypertrophy Muscle fiber conversion Enzyme activity

10. GENERAL CONCEPT OF AEROBICS FITNESS Ability to perform physical work Physical work requires Cardio respiratory functioning Muscular strength Endurance Musculoskeletal flexibility

11. GENERAL CONCEPT OF AEROBICS Maximum oxygen consumptions Capacity of the body to use oxygen Usually used when large muscle groups performing exercises Maximum amount of oxygen consumed/ min Expressed relative to body weight mL /Kg /per minute

12. GENERAL CONCEPT OF AEROBICS ENDURANCE It is an measure of fitness Include muscular & CVS fitness Ability to work for prolong period & resist to fatigue Muscular endurance : Ability of an isolated muscle group to perform repeated contraction over a period of time

13. GENERAL CONCEPT OF AEROBICS CVS endurance : Ability to perform large muscle dynamic exercise e.g. walking ,swimming, for long periods of time
