What else can I help you with?
What is an exercise that is steady and sustained and at which the heart can supply the oxygen needed the body?
Physical fitness
What effect does exercise have on heart rate?
Exercise increases the heart rate, because the blood has to supply additional oxygen to the muscles.
What are 2 things that your muscle rely on?
Muscles during exercise need an adequate supply of glucose and oxygen. Heart rate increases during exercise to provide this supply.
Why does heart rate and respiration go up with exercise?
The more you exercise - the more oxygen your body's muscles need. In order for your heart to supply more oxygen - it must beat faster.
What gas do you need more of during exercise?
During exercise, your body needs more oxygen to supply to your muscles. This is because oxygen is essential for the process of generating energy through aerobic metabolism. Therefore, increasing your oxygen intake through respiration is important to support your muscles during physical activity.
When muscles run low on oxygen?
When muscles run low on oxygen, they switch to anaerobic metabolism and produce lactic acid, leading to muscle fatigue and soreness. This can happen during intense exercise when oxygen demand exceeds supply.
What type of exercise is running?
Running is cardiovascular exercise, because it increases the rate at which the heart pumps blood through your body to supply your muscles with oxygen during their contractions.
What does the human body need a steady supply of?
oxygen
What does the blood supply the muscles with?
oxygen
What happens to the muscles when they are exercised?
The condition depend upon your regularity to do exercise They grow stronger and healthier if you do exercise daily but if you are irregular then whenever you do exercise lactic acid if produced in your muscles as the pryruvate change into lactic acid and a little energy due to less oxygen supply
How does breathing change during exercise and what factors influence these changes?
During exercise, breathing rate and depth increase to supply more oxygen to the muscles. Factors that influence these changes include the intensity of the exercise, the body's oxygen demand, and the level of carbon dioxide in the blood.
What does aerobic exercise do to your muscles?
Aerobic exercise means your muscles are getting exercised at a rate where the muscles are not being depleted of oxygen faster than the blood, from the heart and lungs, can supply it. This allows the muscles to work at maximum efficiency. Aerobic exercise will not reduce the strength, size or endurance of muscles, but it will not help increase them. To work on increasing those, exercise needs to be anaerobic/resistive: high load for short periods. It is best to combine resistive and aerobic exercise to achieve all round strength and fitness.
