WHAT YOU HAVE LEARNT

Three types of physical activities are: aerobic activities, anaerobic activities
and flexibility exercises.
Warming up is the series of exercises done before the main activity which
has physiological and psychological benefits.

In human body we can classify muscles in three groups as per their Note
characteristic and functions; that are smooth muscle, cardiac muscle and
skeletal muscle.

Types, intensity, volume of the physical activity are the component of load.
Skeleton muscle has two types of fibres namely slow-twitch fibres and fast-
twitch ones.

Effects of exercises on muscular system include increased blood supply,
muscle temperature, muscle flexibility, accumulation of lactate acid, micro
tears, DOMS, hypertrophy, increased tendon and ligaments strength, number
and size of mitochondria, myoglobin stores, storage of glycogen, storage of
fat and tolerance to lactate.
Effect of exercise on respiratory system includes increase in respiratory
rate, tidal volume, rate of gas exchange, efficiency of respiratory muscles,
lung volume, pulmonary diffusion and residual volume.

Effect of exercise on circulatory system includes increase in heart rate, stroke
volume, cardiac output, blood pressure, blood volume, blood flow, size of
heart, lactic acid and resting heart rate.

General benefits of exercises include weight control, strong muscles and
bones, boost in energy level, risk of heart diseases decreases, control on
blood sugar and insulin levels, quitting smoking, strengthening
cardiovascular and respiratory systems and reduction in the risk of cancers.
