When muscle cells undergo anaerobic respiration they become fatigued and painful due to the buildup of pyruvate in cells. The pyruvate is converted to lactic acid.

Are there different type of muscles?
There are 3 types of muscles. Striped muscles are the ones that move the bones in your body, like your calf muscles, biceps and thigh muscles. You can feel them and see them. smooth muscles move food through your intestines and also help you swallow. Cardiac muscle is what your heart is made of, and it doesn't get tired.
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.
People with anaemia have fewer red blood cells than normal people these people become breathless and tired easily why?
because if they have fewer red blood cells then they will not be able to absorb as much oxygen (what with haemoglobin and all) this means they must breath more and this, well, is tiring. also respiration requires more oxygen than anaemic people can supply
Why do we get tired?
Many causes. Life is full of stresses. It is the way our bodies tell us to pay attention and that something is needed, for example: fluids, foods and nutrients, rest, relief from infection or parasites, treatment of blood imbalances or disease processes, etc. It can be because we have used or over used our muscles and they need to repair. We get tired when we have low blood sugar and maybe just need to eat to add more calories. We get tired when dehydrated or thirsty. Electrolyte imbalances cause a feeling of being tired. It can be caused by anemia. It can also be a sign of many different disorders, diseases, and autoimmune diseases. Listen to your body when you feel this way and if you can't figure out what is causing the body to give this signal, you may need to seek professional medical help.
Did sloths used to travel at the speed of light but got tired?
No. They never traveled at the speed of light, and have always appeared tired.
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.
How does your body get energy to do what you want it to do?
We need the sun as do many living organisms. Also, we eat, drink and if we're tired we sleep.
How do muscles get tired?
there is force that makes your muscles tired
Products of lactic acid fermentation?
a waste product that must be released from the cell. it is produced when the cell is low on oxygen and converts pyruvic acid.
Exercises that make muscles tired?
All exercises eventually make muscles tired.
What are some ways of soothing tired muscles?
You can sooth tired muscles by getting a massage, or massaging the effected muscles yourself. You can also use a warm compress or icy hot which can help soothe your tired muscles.
What happens when muscles get tired?

Why do lips shake when tired?
The lips may shake when they are tired because the facial muscles may be tense. Tense or tired muscles may shake or tremor.
Why do muscles need more energy when you exercise?
When you exercise you use your muscles and your muscles contain Glycogen which could be considered your "energy source". during exercise your muscles use glycogen depleting your energy levels making you feel tired.
What should you do when your muscles get tired?
Rest.
