  PRINCIPLES OF AEROBIC EXERCISE
• 2.
  Lecture objective  Bythe 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  Aerobicexercises:  is the ability to exercise or compete for a long time without getting breathless.
• 4.
  ANAEROBIC FITNESS  ANAEROBICFITNESS 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 OFAEROBICS  What exercises will you do to get strength  Calves  Quadriceps  Hamstrings  Gluteals  Chest  Latissimus & Rhomboid major
• 6.
  Goals of AnaerobicTraining  Strength  Hypertrophy  Power development  Rehabilitation  Neuromuscular control  Anaerobic metabolism
• 7.
  Anaerobic adaptations Beginning inthe 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 downto the level of individual muscle fibers  Spindle sensitivity  Hypertrophy  Muscle fiber conversion  Enzyme activity
• 10.
  GENERAL CONCEPT OFAEROBICS  FITNESS  Ability to perform physical work  Physical work requires  Cardio respiratory functioning  Muscular strength  Endurance  Musculoskeletal flexibility
• 11.
  GENERAL CONCEPT OFAEROBICS  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 OFAEROBICS  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 OFAEROBICS  CVS endurance : Ability to perform large muscle dynamic exercise e.g. walking ,swimming, for long periods of time
