Knowing the basic rules and benefits
of exercising and regular physical activity can undoubtedly reap beneficial
rewards in the long-term. Increasingly, exercise and physical activity are
treated as one and the same thing.However, there is a big difference between
the two.
Physical
activity is any type of body movement produced by muscle contraction and
which burns calories. Exercise is a subcategory which is
measured by amount, intensity and frequency and involves certain repeated
movements which are structured to improve or maintain one or more physical
components.
Aerobic Activities: Aerobic activities are exercises that move large
muscle mass in legs, torso and arms with cyclic and repetitive movements.
They involve moderate or light effort over sustained periods of time (at
least 15 minutes). For instance some typical aerobic exercises include
walking, swimming, running, cross-country skiing and skating.The intensity
of aerobic activity is measured by heart rate. Improvements from regular
aerobic activity include reductions in adipose tissue (if accompanied by
controlled calorie intake), blood pressure and cholesterol and increases
in general stamina and insulin sensitivity, resulting in improved
glycaemia control.
Building
muscle tone/strength:
Exercises to build muscle tone
increase general muscle strength by using body weight or resistance. This
may involve the use of bands, free weights (dumbbells and barbells) or gym
equipment with counterweights or hydraulic systems.Increasing strength
initially comes by improving muscle contraction and then by increasing
muscle mass. It is not necessary to build up huge muscles to feel the
difference, but it is important to train at a high enough intensity to
obtain results. In other words, generic training has limited benefits in
that it only helps to improve and maintain muscle tone, which is important
for keeping the muscles functioning efficiently.
Increasing Flexibility: Flexibility enables you to perform all the movements
involved in daily life with natural efficiency and ease. Flexibility is
the result of elasticity of the muscle and connective tissues, and you can
achieve it by performing regular stretching exercises. An inactive and sedentary lifestyle
will lead to the progressive loss of elasticity and increase the risk of muscle
tears and changes in posture.The right physical activity can prevent this
type of damage by improving flexibility and correcting bad posture.
