How does the body resting state different from its active state?
During rest, the body's energy expenditure is lower, heart rate and blood pressure decrease, and muscle activity decreases. In contrast, during activity, energy expenditure increases, heart rate and blood pressure rise, and muscles are engaged in movement.
Are there different type of muscles?
Yes, there are three main types of muscles in the human body: skeletal muscles, cardiac muscles, and smooth muscles. Skeletal muscles are attached to bones and facilitate movement, cardiac muscles are found in the heart and help it pump blood, and smooth muscles are found in organs and blood vessels to regulate involuntary processes.
What anatomical fact is responsible for a pianist's forearms becoming tired before the fingers?
The muscles that curl the fingers and allow us to grip objects are in the lower forearm. There are weaker muscles on the top of the forearm that hold the wrist firm against the pull of the others, these muscles on the top of the forearm are most likely to get tired first. The muscles that move each finger side to side are in the palm of the hand, when the muscles for moving the finger sideways are used at the same time against each other they can be used to extend the fingers. These small muscles in the palm provide much greater control and relive stress from the forearm. This is why it is important to relax the arms, hands, and wrists while playing, keep the fingers arched and position the finger in place on the key, then press forwards, with practice it becomes a smooth, quick and controlled motion.

Why muscles get tired?
Muscles get tired due to the buildup of lactic acid, a byproduct of energy production in the absence of sufficient oxygen. This can lead to decreased muscle function and a feeling of fatigue. Additionally, depletion of energy stores such as glycogen and the accumulation of metabolic byproducts can also contribute to muscle fatigue.
When muscles are contracting under oxygen deficient conditions what is formed to ensure they maintain a supply of ATP?
Muscle cells produce lactic acid during anaerobic fermentation. A buildup of lactic acid cause your muscles to feel tired.
What makes us slow down when we have done a couple of laps?
As we exercise we burn food faster. This needs the supply of oxygen to the muscles. There is a limit to how fast it can be delivered so we turn to anaerobic respiration, which results in the build up of lactic acid. This makes the muscle tired.
