Exercises are categorized into two types.
– Anaerobic, and
Anaerobic – without oxygen and Aerobic – with oxygen will sum up what is meant by them.
Anaerobic exercises activiate the fast twitching muscle fibers in the body. Mitochondria which plays a very important role in the body metabolism is normally the in-focus constituent in aerobic and anaerobic activity.
The mitochondria are found at the periphery of the aerobic fiber but are spread in the interior of the anaerobic fiber. The mitochondria are naturally at the periphery, because the oxygen they need can only come from outside the cell. The fatty acid stores are then placed near the mitochondria, because that is where they will be metabolized. The anaerobic fibers have no need for myoglobin since they have no mitochondria and as such are referred to as pale muscle fibers.
Anaerobic exercise comprises brief, strength-based activities such as sprinting or bodybuilding, whereas aerobic exercise is centered around endurance activities such as marathon running or long distance cycling.
Human beings have varied body structures. We need to understand the basic body structure we possess and cater to specific exercises that will give us the maximum benefits.
Body types are categorized as
a) Ectomorphs are thin, slim and underweight people. Examples of ectomorph are marathon runners, swimmers, basketball players.
b) Mesomorphs are strong and have an athletic build. Those with mesomorph body structures can develop and build (muscle) mass easily without much difficulty and can eat more without fear of gaining weight. Examples are baseball players, soccer players, rugby players.
c) Endomorphs are those who get obese easily and are people who benefit a lot by anaerobic activity such as weight lifting, rowing etc.
Most of us are not really aware of the difference between weight training, bodybuilding, and powerlifting.
Bodybuilding is the process of developing muscle fibres through the combination of weight training, increased caloric intake, and rest.
Weightlifting is a sport where competitors attempt to lift heavy weights mounted on steel bars, the execution of which is a combination of power and technique.
Powerlifting is a strength sport, consisting of three events: the squat, the bench press, and the deadlift. The maximum weight lifted in each event is totalled for a final score.
