oxygen is breathed into the lungs where 'gaseous exchange' takes place, this transfers the oxygen to the blood supply (circulatory system) which already contains various substances ie. food etc. Oxygen is taken via the blood capilary network to the muscle cells 'mitchocondria' where 'airobic resperation' takes place, this involves the food being broken down using the oxygen, releasing energy to the cells and producing carbon dioxide and water as byproducts.
The respiratory system works to bring oxygen into the body through inhalation and transport it to the muscles via the bloodstream. The circulatory system then delivers oxygenated blood to the muscles and removes carbon dioxide produced during exercise. Together, these systems help maintain adequate oxygen levels for the runner's muscles during physical activity.
You can indeed get defined ab muscles during the summer months. This simply requires working out and eating good foods.
The middle layer is formed during the gastrulation. This layer develops into muscles, bones and blood vessels.
Yes, the circulatory system is used in baseball to deliver oxygen and nutrients to the muscles to help them function during gameplay. It also helps remove waste products, such as lactic acid, from the muscles to prevent fatigue. Overall, a healthy circulatory system is essential for optimal performance in baseball.
Same as at rest, but slower, all via the circulatory system. The distribution is different too - during exercise the muscles that are actually working (using oxygen) get a much higher blood flow than those tissues at lower metabolic states.
Working muscles produce carbon dioxide and lactic acid as waste products during physical activity. When muscles metabolize glucose for energy, carbon dioxide is generated and transported to the lungs for exhalation. Lactic acid accumulates during anaerobic respiration, especially during intense exercise, and can contribute to muscle fatigue.
Your abs are sore after working out because the muscles in your abdominal area have been stressed and slightly damaged during the exercise. This leads to inflammation and the sensation of soreness as your muscles repair and strengthen themselves.
After working out, your muscles may feel smaller due to a temporary decrease in muscle size caused by the breakdown of muscle fibers during exercise. This is a normal part of the muscle recovery process and does not necessarily mean that your muscles are actually shrinking.
Many reasons: Putting too much exertions on weak muscles working out or lifting wrong heavier: therefore more strain on muscles
quads (narrow squats) & gluteals & hamstrings (wide-positioned squats)
heart pumps faster.
Core exercise is important, because it help strengths the core muscles. Core muscle training will also strengthen other muscles during the training.
