When During exercise the heart muscle's oxygen requirements increase decrease or remain the same?
During exercise, the heart muscle's oxygen requirements increase significantly to meet the heightened demand for blood flow and energy. As physical activity intensifies, the heart pumps faster and harder, requiring more oxygen to support the working muscles. This increased demand is met by an increase in heart rate and stroke volume, ensuring that sufficient oxygen-rich blood is delivered throughout the body.

What does FITT mean in sport?
Specificity - Choosing a type of exercise that is related to the sport you do. Progression - Gradually progress/increase the exercise you are doing. Overload - Doing more exercise than what the muscles are used do. Reversibility - The muscles slowly decrease in strength due to a stop in exercise. Tedium - Varies of different exercising do prevent boredom. Frequency - How often you exercise. Intensity - How hard you exercise. Time - How long you exercise for. Type - The type of exercise you do.
What in muscle cells increase as a result of exercise?
Muscle cells increase in size (hypertrophy) and in number of mitochondria, which are responsible for producing energy. Additionally, exercise can lead to an increase in the concentration of myoglobin, which helps store and transport oxygen in the muscles.
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.
How does excercise help your muscles?
Exercise help you increase the quantities of Actin and Myosin as well as increase the size of your muscle

What is capillarisation?
a capillary is our body's smallest form of blood vessel the more capillary's at the muscles, the more oxygen the muscles can use an increase in capillarisation means that there is an increase in blood vessels and subsequently an increase in the opportunity for blood (and oxygen) to be transported to and used by the muscles a decrease in capillarisation means that there is a decrease in poo vessels and subsequently a decrease in the opportunity for blood (and oxygen) to be transported to and used by the muscles aerobic or endurance training does well to bring about an increase in capillarisation, meaning that muscles can perform for longer peroids of time as they are able to use more oxygen for contraction
How can you increase body muscles?
You can increase your muscles by doing regular exercise. gradually increasing resistance. following a proper diet and achieving proper rest...your muscles grow while resting not while working out....
What effect does resistance exercise have on muscle mass?
Resistance exercise exerts particular muscles, and as a response, the muscles hypertrophy, causing them to grow larger and increase their work capacity.
How does exercise increase myoglobin stores?
Myoglobin is a protein within the muscle tissue which acts as an oxygen carrier. As a long term effect of exercise. The ability of the muscles to store myoglobin is increased. Because muscles increase their oxidative capacity through regular exercise, the myoglobin stores also increase because they get used to the demands of exercise and work placed upon them so increase stores as they will be needed. The increase in oxidative capacity is achieved by an increase in the number of mitochondria within the muscle cells, an increase in the supply of ATP and an increase in the quantity of enzymes involved in respiration.
What the type of exercise for muscle strength?
By using your muscle you are strengthening them so all you have to do is use them to increase the strength of the muscles increase the load.
Does atrophy of muscles cause a increase in size?
atrophy is a decrease in muscle mass. Hypertrophy is muscle growth.
How does exercise increase the strength of diaphragm?
Intercostal muscles increase in strength due to being repeatedly used in exercise, so to strengthen them you will have to do endurance training. The stronger the intercostal muscles the more air you can inhale as they pull your rib cage out giving you a larger thoracic cavity.
