Aerobic Exercise
Aerobic Exercise is any physical activity that makes you sweat, causes you to breathe harder, and gets your heart beating
faster compared to when you are at rest. Doing aerobic exercises regularly strengthens your heart and lungs and trains your
cardiovascular system to manage and deliver oxygen more quickly and efficiently throughout your body. Aerobic exercise
uses your large muscle groups, is rhythmic in nature, and can be maintained continuously for at least 10 minutes.
Accurate measurement of exercise heart rate is crucial in monitoring exercise intensity. In order to measure the heartbeat
per minute, one must be knowledgeable of the specific points in the body where the heartbeat can be felt. There are four
techniques in getting the heart beat per minute, and they are as follows.
Aerobic fitness is the ability of the body’s cardiovascular system to supply energy during continuous physical activities such
as biking and running. Studies show that this type of exercise provides many health benefits such as decreasing risk for
heart disease, stroke, high blood pressure, type II diabetes and some cancers. Examples of aerobic activities include walking
at a brisk pace, swimming, jogging, dancing, etc.
Muscular strength is the ability of the muscles to exert a force during an activity such as lifting weights. Muscle strengthening
exercises involve using your muscles to work against a resistance such as your body weight, elastic bands or weights.
Bone strengthening exercise, or any weight-bearing activity that produces a force on the bone, is also important to
overall health for children and adults. This force is usually produced by impact with the ground and results in bone growth
in children and healthy maintenance of bone density in adults. Examples of bone strengthening activities include jumping,
walking, jogging, and weight lifting exercises. As you can see, some exercises such as walking or jogging serve a dual
purpose of strengthening our bones and our aerobic system.
Muscular endurance, on the other hand, is how many times you can lift a certain amount of weight. Resistance training
(also referred to as weight training or strength training) helps increase muscular strength and endurance.
Resistance Training. Strength exercises, such as weight lifting, push-ups and crunches, work your muscles by using
resistance (like a dumbbell or your own body weight.) This type of exercise increases lean muscle mass, which is particularly
important for weight loss, because lean muscle burns more calories than other types of tissue.
Circuit training.
It is when you alternate between several exercises (usually five to 10) that target different muscle groups.
Flexibility exercises stretch your muscles and may improve your range of motion at your joints. They can improve your
flexibility and reduce your risk of injury during sports and other activities. It is usually done in warm-up exercise to condition
the muscle and in the Cooling down exercise to allow the body to gradual transition in a resting or near-resting state.
Static stretching is most often recommended for general fitness. With this type, you slowly ease into the position and hold
for 10 to 30 seconds before slowly releasing the stretch. Static stretching should be performed with warm muscles, such as
after a warm-up or at the end of a workout. There are two forms of static stretching.
Active Static: This form of stretching is used in yoga and martial arts. The stretch is held by the strength of agonist muscles
(muscles responsible for the movement). Think of the stretch across the upper body during the Warrior II pose in yoga. Your
arms are extended as your back, chest, and shoulders are stretched. The muscles of the arms and shoulders are the agonist
muscles that allow you to hold this stretch.
Passive Static: During this type of stretching, you hold the limb to perform the stretch without any assistance such as a bar
or bands. Think of a standing quadriceps stretch in which you bend your leg behind you and hold the foot, pulling the heel in
close to your bottom, which stretches the front of the upper thigh.
Dynamic Stretching is stretching with movement. The body transitions gradually into a position and this movement is
repeated as you increase your reach and range of motion. Research has found that dynamic stretching is less beneficial
than static stretching for increasing range of motion, but unlike static stretching, it is ideal during the pre-workout phase
because it gently warms muscles while also stretching them.
How Do I Assess My Fitness Level
You probably have some idea of how fit you are but assessing and recording baseline fitness scores can give you
benchmarks against which to measure your progress. To assess your aerobic and muscular fitness, flexibility, and body
composition, consider recording:
✓ Start recording your pulse rate.
For most of us, between 60 to 100 beats per minute (bpm) is normal. The rate can be affected by factors like stress,
anxiety, hormones, medication, and how physically active you are. An athlete or a more active person may have a resting
heart rate as low as 40 beats per minute.
When it comes to resting heart rate, lower is better. It usually means your heart muscle is in better condition and
doesn’t have to work as hard to maintain a steady beat. Studies have found that a higher resting heart rate is linked with
lower physical fitness and higher blood pressure and body weight.
For moderate-intensity physical activity, your target heart rate should be between 64% and 76% of your maximum heart
rate. You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate,
subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would
be calculated as 220 – 50 years = 170 beats per minute (bpm). The 64% and 76% levels would be:
• • 64% level: 170 x 0.64 = 109 bpm, and
• • 76% level: 170 x 0.76 = 129 bpm
This shows that moderate-intensity physical activity for a 50-year-old person will require that the heart rate remains
between 109 and 129 bpm during physical activity.
For vigorous-intensity physical activity, your target heart rate should be between 77% and 93% of your maximum heart
rate. To figure out this range, follow the same formula used above, except change “64 and 76%” to “77 and 93%”. For
example, for a 35-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 35 years =
185 beats per minute (bpm). The 77% and 93% levels would be:
• • 77% level: 185 x 0.77 = 142 bpm, and
• • 93% level: 185 x 0.93 = 172 bpm
This shows that vigorous-intensity physical activity for a 35-year-old person will require that the heart rate remains between
142 and 172 bpm during physical activity.
What are the principles of exercise that I can use as my guide in my fitness plan?
A successful exercise program incorporates a number of general principles in order to make the training safe and
effective, helping us to achieve our goals.
Principle of Specificity
We've all heard the phrase, "Practice makes perfect." Well, this is the Principle of Specificity in action. This principle
simply states that exercising a certain body part or component of the body primarily develops that part. The principle of
specificity implies that to become better at a particular exercise or skill, you must perform that exercise or skill. A runner
should train by running, a swimmer by swimming and a cyclist by cycling. While it's helpful to have a good base of fitness
and to do general conditioning routines, if you want to be better at your sport, you need to train specifically for that sport.
Principle of Overload
The exercise science principle of overload states that a greater than normal stress or load on the body is required for
training adaptation to take place. What this means is that in order to improve our fitness, strength or endurance, we need
to increase the workload accordingly.
In order for a muscle (including the heart) to increase strength, it must be gradually stressed by working against a load
greater than it is accustomed to. For adaptation to occur the volume of exercise must overload the body in some way in
line with the capacity of the individual to cope with that overload.
Principle of Progression
The principle of progression implies that there is an optimal level of overload that should be achieved, and an optimal
time frame for this overload to occur. A gradual and systematic increase in the workload over a period of time will result in
improvements in fitness without risk of injury. If overload occurs too slowly, improvement is unlikely, but overload that is
increased too rapidly may result in injury or muscle damage. For example, the weekend athlete who exercises vigorously
only on weekends violates the principle of progression and most likely will not see obvious fitness gains.
The Principle of Progression also stresses the need for proper rest and recovery. Continual stress on the body and
constant overload will result in exhaustion and injury. You should not train hard all the time, as you'll risk overtraining and
a decrease in fitness.
Principle of Adaptation
Adaptation refers to the body's ability to adjust to increased or decreased physical demands. It is also one way we learn
to coordinate muscle movement and develop sports-specific skills, such as batting, swimming freestyle, or shooting free
throws. Repeatedly practicing a skill or activity makes it second-nature and easier to perform. Adaptation explains why
beginning exercisers are often sore after starting a new routine, but after doing the same exercise for weeks and months
they have little, if any, muscle soreness.
Additionally, it makes an athlete very efficient and allows him to expend less energy doing the same movements. This
reinforces the need to vary a workout routine if you want to see continued improvement.
F.I.T.T. Principle
Frequency = How often you exercise
Intensity = How hard you exercise
Time = How long you exercise
Type = What kind of exercise
The F.I.T.T. Principle is one of the foundations of exercise, a set of guidelines that help you set up a workout routine for
maximum benefit.
