Static stretches are part of an effective cool down because they can help
increase range of motion
Warming up is important before exercising to
prevent injury
It is important to avoid isostatic stretches because they can
extend a joint beyond its regular range of motion
To warm up before a run, Lucas walks for five minutes. Which of these accurately
evaluates his choice of warm-up activity?
This activity is appropriate because it prepares muscles for more intense movement.
A static stretch is
safe, because it stretches the muscle and joint without causing pain
MUSCLES
All exercises involve muscles; they are biochemical motors that use energy to provide
the movement and power your body's activity needs. Cellular respiration and anaerobic
respiration are reactions in the muscle cells that convert stored chemical energy from
carbohydrates or fat to energy that can be used for muscle movement.
HEART
The blood might carry the oxygen to muscles, but the heart is what gets the blood
moving! As you work out, you will feel your heart rate increase as it pumps the blood out
throughout the body. Maximum oxygen uptake (VO2 max) is a measure of how much
oxygen your body takes in and distributes to muscles during exercise. Your heart rate
and the volume of blood pumped with each heartbeat play a big role in your aerobic
capacity. The good news is you can work to improve your aerobic capacity. The heart is
a muscle, so it can be strengthened by regular exercise in the proper target heart rate
zone.
LUNGS
During exercise, the rate and depth of your breathing increases as your lungs work to
bring in more oxygen and release carbon dioxide, which is formed by cellular
respiration. Regular exercise actually strengthens the muscles that expand and contract
your lungs. Strengthened muscles make it easier to meet oxygen demands that keep
your muscles moving to complete your workouts
SKIN
Muscle movement and cellular and anaerobic respiration all produce heat, increasing
your body temperature as you exercise. Your body attempts to release this extra heat
by dilating blood vessels (evident by warm, flushed skin) and increasing perspiration,
also called sweat.
NERVOUS SYSTEM / BRAIN
Endorphins are chemicals that produce a feeling of well being when they are released
into your bloodstream. They are produced by the pituitary gland and the hypothalamus
during long, continuous exercise or extreme excitement.
PERSPIRATION
Sweat keeps body temperature in a safe range. As it evaporates, it removes heat from
the skin's surface and brings down the body's temperature. However, sweating also
, removes water and ions, like sodium and potassium, from the body, so it is important to
stay hydrated with plenty of water or even a sports drink
Blood
Oxygen from your lungs is carried throughout the body by the blood. Working muscles
can take oxygen out of the blood about three times as fast as resting muscles, and that
efficiency is very important! Your body also adapts to demanding physical activity by
dilating the blood vessels for increased blood flow, pumping the heart faster, increasing
the amount of oxygen carried in the blood, and diverting blood flow away from
nonessential organs like the stomach, kidneys, and liver during exercise.
Replenish
Immediately after exercise, your body works to replenish fluid and stored energy. That
means it is important to drink water and eat healthy food in the hours after a workout.
Repair
You might experience delayed onset muscle soreness after a workout. It is the
temporary severe soreness, stiffness, or pain that you feel in muscles after strenuous
exercise. The damage to the muscles can occur from 24 hours to three or more days
after strenuous exercise. As you rest, the body's efforts shift to protein synthesis to
repair the muscles. This helps prevent future damage and soreness the next time you
repeat that exercise.
Rest
The time between exercises is important for the repair of muscles, tendons, and
ligaments. Your muscles will feel fatigued and sore, so it is important to rest those
specific muscles a day or two before you work them at a high level again. Rest also
gives the body time to remove chemicals that build up from cellular function during
exercise. This doesn't mean you should lie on the couch for two days, but do alternate
your activities so you work different muscle groups on consecutive days.
Heart Rate
Take your pulse or use a heart rate monitor to make sure you are keeping your heart
rate within your target heart rate zone. If it's too low, you won't see as many benefits; if
it's too high, you could cause harm.
Talk Test
If you can talk for long periods of time but are not able to sing, then you are exercising
at a moderate, safe heart rate level. If you can have a short conversation, then you are
exercising at a vigorous, yet safe, heart rate level.
Breathlessness, gasping for breath, and not being able to talk normally during exercise
are warnings to lower the level of your exercise.
Thirst
Be sure to keep hydrated before, during, and after a workout. If you are feeling thirsty,
that means your body could already be dehydrated, and you should drink more water as
soon as possible.
How is perspiration related to recovery after exercise?
The water and ions lost through perspiration must be replaced during recovery so the
body can replenish fluid and stored energy.
During exercise, the amount of ____________ carried in the blood to the muscles
increases.
oxygen
