What else can I help you with?
What causes muscle fatigue and how do you know if you are expreiencing muscle fatigue?
By a muscle that fails to relax completely resulting in the muscle going into spasm.
Why does the burning sensation associated with muscle fatigue occur due to the accumulation of?
The burning sensation during muscle fatigue happens because of the buildup of lactic acid in the muscles.
Muscle fatigue in human results from the overproduction and accumulation?
of lactic acid due to anaerobic metabolism. This leads to a decrease in pH levels in muscles, which interferes with muscle contractions and contributes to the feeling of fatigue. As a result, muscles are unable to generate as much force or sustain prolonged activity.
Inability of muscle fibers to contract after a long period of contraction?
This is likely due to muscle fatigue, which happens when muscle fibers become depleted of energy sources like ATP needed for contraction. Accumulation of waste products like lactic acid and a decrease in calcium availability can also contribute to muscle fatigue. Rest and replenishing energy sources can help muscles recover and regain the ability to contract.
When does muscle fatigue occur?
Muscle Fatique occurs when low o2 conditions deplete Atp and cp stores acaerobic respiration creates lactic acid. drops in ph and o2 debt lead to failure of the muscle to maintaain contractions
When a muscle is being stimulated but is not able to respond due to oxygen debt the condition is called?
Fatigue
What causes a muscle cramp to occur?
A muscle cramp occurs when a muscle involuntarily contracts and does not relax. This can happen due to dehydration, muscle fatigue, lack of stretching, or mineral imbalances like low levels of potassium or calcium.
The buildup of waste products in muscle cells that are active might cause?
The buildup of waste products in muscle cells that are active can cause fatigue, soreness, and a decrease in performance. This accumulation can lead to a decrease in muscle function and athletic ability due to a decrease in oxygen and nutrient supply and an increase in waste product concentration.
How does the body's production of lactic acid during intense exercise affect muscle fatigue and performance?
During intense exercise, the body produces lactic acid as a byproduct of energy production. Accumulation of lactic acid can lead to muscle fatigue and decreased performance due to the build-up of acidity in the muscles, which can impair muscle function and lead to discomfort.
What happens at the cellular level during muscle fatigue?
During muscle fatigue, affected muscle groups lose the ability to generate force and the individual will experience a sensation of weakness. Muscle fatigue is comprised of two types of fatigue: neural and metabolic.
What organic molecule accumulates when oxygen debt occurs?
Lactic acid accumulates when oxygen debt occurs due to anaerobic metabolism in muscles. This buildup leads to muscle fatigue and soreness.
What causes muscular fatigue after just a few minutes of intense exertion?
Reduction in the effectiveness of a muscle or muscle group reflected by a decline in peak tension. Local muscular fatigue may be due to one or more reasons, such as failure of a motor nerve to transmit nerve impulses to the muscle; fatigue at the neuromuscular junction through depletion of neurotransmitters; inability of the contractile mechanism (the actin and myosin myofilaments) to generate force; accumulation of protons from lactic acid in the muscle; depletion of ATP and phosphocreatine; or failure of the central nervous system to initiate and relay nerve impulses to the muscle. The most probable sites of local muscular fatigue are the neuromuscular junctions, the contractile mechanism of the muscle itself, and the central nervous system. Fatigue at the neuromuscular junction, which might be more common in fast twitch fibres, is probably due to depletion of http://www.answers.com/topic/acetylcholine. Fatigue within the contractile mechanism may be caused by accumulation of protons, depletion of ATP and phosphocreatine; depletion of muscle glycogen; dehydration; or lack of oxygen and inadequate blood flow.
