Exercise demands energy.Our muscle cells produces instant energy by breaking down ATPs,otherwise known as energy coins inside a living system.Which can be utilized at the time of need.Energy in turn could only be incorporated to ATPs by burning or biologically oxidating the primary food stuffs,which requires oxygen.The mitochondria in a living cell can generate a good lot of ATPs aerobically(presence of oxygen) by breaking down sugars vide TCA cycle & electron transport chain.But when oxygen is scarce as during exercise,the system adapts a different strategy to produce energy. It goes through an anaerobic(absence of oxygen) path called glycolysis.The energy produced (ATPs generated) in later is comparatively less then the former.And to add to the sequence,another side effect of accumulation of lactic acid occurs.Accumulation of which accounts for muscle fatigue,which we all experiences after a hectic sports schedule is over.We take long gasping breathes to wash lactic acid out & oxygen in to come back to normalcy again.
After a workout or continuously doing something your muscle starts to fatigue it seems to hurt when moved or move slowly.
Fatigue
Fatigue.
To get larger muscles go for high weight and fatigue the muscles with low repetitions. To get toned muscles go for lower weight and high repetions to fatigue the muscles.
fatigue
Muscle fatigue is caused by an accumulation of lactic acid in muscles.

Muscle fatigue
peripheral fatigue originates in the exercising muscles; central fatigue begins in those various areas of the brain working in concert, and which sent efferent signals to the working muscles to ease strength of contraction in order to preserve homeostasis.
When a person is performing intense physical exercise and begins to feel fatigue and a burning pain in the muscles the response of the muscles is to synthesize more lactate or lactic acid.
These anti fatigue mats are designed to help people reduce fatigue. This is done by drawing tension from muscles and helping people become relaxed.
Cardiac muscles can work without fatigue.
working your muscles too hard will lead to muscle fatige
