Exercise Basics
Exercise Basics by Karen Skidmore, ATC
With all the nutrition and fitness hype around these days, how
do you know what is correct and what isn't? The intentions of
this article are to help you identify factual and effective
information regarding current fitness trends.
Total health is threefold - aerobic exercise and resistance
training are addressed in this article. The third part, healthy
eating, will be examined in a future article.
Diet and supplements alone will not get you the physique you
want. You must make exercise a part of your weekly routine.
Exercise will help to boost your metabolism, change your body
composition and decrease your carbohydrate sensitivity.
AEROBIC EXERCISE
The American College of Sports Medicine (ACSM) defines aerobic
exercise as "any activity that uses large muscle groups, can be
maintained continuously, and is rhythmic in nature." This can be
any continuous rhythmic activity that keeps the heart rate
elevated in the target zone for the length of the workout.
Aerobic activity must be done for a minimum of 30 minutes a day
at least 3 times a week. Your goal for aerobic exercise is 4 - 5
times a week for 45 minutes to one hour. This is the same type
of exercise that, when done over time, will help to improve the
condition of the heart and lungs.
Examples: Walking, jogging, cycling, stairs, cardio machines,
swimming, and circuit training.
RESISTANCE TRAINING
Resistance training is a term used to cover all types of weight
training. This type of training is beneficial in many ways.
Primarily, muscle is more metabolically active than fat, so you
burn more calories while at rest. Other benefits include a
decreased risk for osteoporosis and an increase in bone mass.
Resistance training should be done twice weekly incorporating 1
- 3 sets of exercises for each of the major body parts.
"No pain no gain." Let's clear the air on this age old
misconception. Bodybuilders and athletes coined this phrase
because they felt that if their workouts did not leave them in
pain, they did not work hard enough to gain any benefits. It is
true that during resistance training you may feel a slight burn
or uncomfortable feeling in the muscle; this is a natural
reaction when placing a muscle under stress. However at no time
should you feel sharp pain or
pain in the joints. On occasion
there will be a mild soreness after the workout and even
soreness 1 - 2 days after the workout. This is a normal
reaction, as you workout you have a temporary build up of lactic
acid, that is eventually cleared out by the recovering muscles.
A proper warm up and cool down is as important as the actual
workout. Mentally these two will prepare the body for the
workout and allow the body to return to normal activity in a
comfortable manor. A warm up will allow the bodies' metabolic
processes a chance to catch up with the increased work load in a
more proficient manner helping avoid premature fatigue. It will
cause a gradual increase in muscle temperature which will help
reduce the chance of injury. A cool down will aid in the removal
of lactic acid which in turn will help with muscle soreness.
Also it will help the body return blood to the heart and
eliminate venous pooling, which leads the feeling of dizziness.
Lastly a cool down helps lower the levels of adrenaline in the
bloodstream. Any adrenaline that lingers in the bloodstream
after the workout can place unnecessary stress on the heart.
Flexibility is the movement or lack of movement we have in our
joints. We do stretching exercises to improve these movements.
The exercises done to improve our flexibility should always be
done at the end of a workout. They can be incorporated right
into the cool down. The reason for this is our muscles are much
like rubber bands, they have elastic properties and when they
are stretched they go back to their original form. If you
stretch while the muscles are cold just like the rubber band
they do no go back to the original form and you run the risk of
having an injury. For improved flexibility stretching exercises
should be done everyday.
