Types of Exercise
Depending
on the purpose for you doing exercise, there are a variety of types of exercise
available to you. For example, if you're trying to improve stamina and your
circulatory system, aerobic exercise would benefit you.If you're trying to
build muscle, then flexibility and weights would be the proper choice. Whatever
you goals are, you'll be able to find the type of exercise appropriate for you,
and an exercise regimen that will of the proper intensity and gradient so that
you can win with an exercise program.
There
are two types of exercise:
1. Aerobic
2. Anaerobic
What
is Aerobic Exercise
The
word aerobic is made up of two Greek words: Aeros meaning air and Bios meaning
life.
Aerobic
exercise is vigorous enough to increase the body's need for oxygen and hence
air intake and breathing rate increase.
Aerobic exercise is done at a pace that allows an adequate supply of
oxygen to reach your muscles as you work out.
If you can hum to yourself or carry on a conversation as you work out
then you are probably exercising aerobically.
This type of exercise can be continued for 20 - 45 minutes without being
exhausting.
Some
Examples of Aerobic Exercise include:
Swimming,Brisk
Walking,Cycling,Jogging,Rowing,Aerobics classes
What
is Anaerobic Exercise?
Anaerobic
means literally without air or oxygen. A
term applied to microbes which can thrive only in the absence of oxygen; but it
also refers to the converse of aerobic exercise, where sustained intensive
exercise (eg sprinting) exceeds the body's capacity to deliver oxygen so that
the muscles use energy derived from anaerobic metabolism resulting in an oxygen
deficit which has to be replenished later. Anaerobic exercise involves intense
or explosive spurts of strenuous activity that leaves you gasping for
breath. This exercise can only be done
for a minute or too at a time, because it depends on limited stores of
glycogens (sugars) stored in the muscles, which are rapidly depleted, resulting
in intense muscle fatigue.
Examples
(of anaerobic exercise)
Weight
lifting,Sprinting
Best
Types Of Exercise
The
best types of exercise combine 3 elements:
1. Stamina
2. Strength
3. Suppleness
There
are many different types of aerobic exercise and which one is best for you to
use is dependent on your time limits, financial and physical limitations, and
personal choice. Low impact exercises like walking, swimming and cycling are
probably the cheapest and most practical types of aerobic exercise to take.
These supply the benefits without the risks of injuries such as back and
knee-joint problems that can occur in high impact exercise like jogging.
Walking and swimming are relatively cheap, you don't have to pay gym fees and
require little in the way of special sports clothing or equipment. You can use different ones daily. The important thing to bear in mind is that
it has to be aerobic for 20 minutes.
You
need to add resistance or weight-training to your programme as lifting is an
important component of exercise because it increases your strength.
A
good exercise programme includes 3 types of exercise:
1. Stretching (to improve flexibility)
(Yoga, Tai Chi).
2. Endurance (aerobic) to improve cardio
fitness.
3. Strength training (weight training).
It
is wise, if suffering from stress, to avoid competitive types of exercise as
research indicates competitive exercise can be stressful instead of
relaxing. So walking, swimming, cycling
etc., are good, non-competitive aerobic exercise, but competitive exercise for
example, squash and tennis, should be avoided.
Exercise should not be used in isolation but in order to get maximum
stress reduction benefits, it should be used along with relaxation, nutrition,
Tai Chi, etc.

What is Doping
'Doping'
is the word used in sport when athletes use prohibited substances or
methods to unfairly improve their sporting performance.
Doping in sport remains a serious and difficult issue, putting
an athlete’s health at risk whilst also threatening the integrity of
clean athletes and the reputation of sport.
Substances and methods are banned for a reason. Doping, the use of
artificial enhancements to gain an advantage over others in competition,
is cheating and is fundamentally contrary to the spirit of sport.
Further, doping robs true athletes who play by the rules of their right
to competition that is safe and fair.
Doping affects not just top athletes, but also future generations who
may be influenced by what top athletes do. Only by taking a concerted
and comprehensive approach to the fight against doping in sport is it
possible to protect the integrity of sport, the health of athletes, and
young aspiring sports people worldwide.
It is integral to the nature of sport itself that spectators and
participants of all sports are confident that the competition is fair
and clean. (http://www.ukad.org.uk/what-we-do/about-doping/)
