            Aerobic Activities


            Aerobic activities are those activities which are performed continuously with
            low and moderate intensity by the large groups of muscles, oxgen uptake is
            high. These activities  require oxygenated blood for working muscles.  For
            example, walking, running, skipping, swimming, rowing, hiking. Production of
            lactic acid in muscles in these activities is low.

            Anaerobic Activities

            Anaerobic activities are those activities which are performed in intervals with
            moderate to high intensity and low volume. The activity is either too fast or too
            intensive in which working muscle is unable to receive appropriate amount of
            oxygenated blood that triggers lactate acid formation. Sprinting, weight training
            etc. are suitable examples.

            5.1.4 Components of Physical Activity

            Effect of exercise or physical activity on body system depends on below
            mentioned factors:
                 Types of Physical Activity: Different physical activities have varied energy
                 demand, involvement of body parts, coordination & equipment used which
                 produces a wide-range of load. Examples: running, weight lifting, playing
                 tennis, playing kick boxing, badminton etc.
