Why do intercostal muscles increase in strength during exercise?
the muscles of the diaphragm and intercostals increase in strength, allowing for greater expansion of the chest cavity.
Why does blood flow quicker during exercise?
Because the heart beats faster during exercise to ensure that oxygen gets to the working muscles.
During exercise a lot more blood is distributed to the working muscles how is this achived?
heart pumps faster.
What molecule increases in the blood during exercise?
During exercise our blood circulation speed increases. It effect in amino acid and a molecule ATP which causes muscles to increase strength.
Can you exercise your heart like the other muscles in your body?
Absolutely. When you get your heart racing during (typically aerobic) exercise, you increase its ability to pump blood.
How does exercise increase blood oxygenation?
During aerobics exercise, lungs take in air and transfer oxygen to the blood, which is then pumped by the heart to the muscles that need it.
Why does heart beat increase during exercise?
Because the heart has to pump more oxygen than usual to your muscles
What happens to the pH in exercising muscles?
When exercising the pH in the muscles becomes more basic. This is because an increase in temperature in the muscles during exercise reduces the attraction pf haemoglobin with oxygen.
Why do you breathe faster during exercise than during sleep?
Exercise places greater oxygen demands on the body, therefore signaling the respiratory center to increase the rate of respiration in order to increase the oxygen supply to the body's muscles and other tissues.
Why do you get a burning sensation in your muSCles during strenuos exercise?
Your limbs burn when you exercise because you are working the muscles hard. Even when your working out, like lifting weight even if its lower than what you can do after so many reps your limbs will start burning because of the muscle.
What happens to your heart rate when you excercise?
Depending on how light or heavy exercise is will depend on the change that occurs. Typically during exercise heart rate will increase. This is in order to increase blood flow to the working muscles to allow for increased respiration - in order for the muscles to work efficiently. Therefore the more strenuous the exercise, the more your heart rate will increase. Blood pressure will also increase during exercise and again depends on intensity levels. During exercise such as running/cycling/swimming systolic pressure will increase progressively whereas diastolic pressure will increase only slightly. During weight lifting exercises, both systolic and diastolic pressures will rise. Obviously these effects will vary from person to person, depending on age, gender, exercise level, exercise intensity etc. etc.
What can you do to increase the amount of time before your muscles fatigue?
The only way to increase the amount of time before your muscles fatigue is to slowly increase the amount of time you workout. You should also increase your fluid intake during your exercise routine.
