Acute muscle soreness

Source: Wikipedia, the free encyclopedia.

Acute muscle soreness (AMS) is the pain felt in

physical exercise. The pain appears within a minute of contracting the muscle and it will disappear within two or three minutes or up to several hours after relaxing it.[1]

There are two causes of acute muscle soreness:[1]

  • Accumulation of chemical end products of exercise in muscle cells such as lactic acid and H+
  • Muscle fatigue (the muscle tires and cannot contract anymore)

Cause

Muscle soreness can stem from strain on the

inflammatory cells and cytokines stimulate the pain receptors that cause the acute pain associated with AMS. Repair of the sarcomere and the surrounding connective tissue leads to delayed onset muscle soreness, which peaks between 24 and 72 hours after exercise.[citation needed
]

AMS may also be caused by cramping following strenuous exercise, which has been theorized[by whom?] to be caused by two pathways:

Dehydration

The dehydration theory states that

sweating, causing the volume to decrease to the point until the muscles are contracted until the fluids can re-inhabit the vacuum.[3] Excessive sweating can also cause the electrolyte imbalance theory, which is sweating disturbs the body's balance of electrolyte, which results in exciting motor neurons and spontaneous discharge.[citation needed
]

The feeling of soreness can also be attributed to the lack of contraction from the muscle, which can lead to overexertion of the muscle. The decrease in contraction has been theorized to have been caused by the high level of concentrations of proton created by glycolysis.[3] Excess in protons displaces calcium ions which is used within the fibers in activating the sarcomere, resulting in a reduced contractile force.[citation needed]

Electrolyte imbalance

When exercising,

muscle fiber, which will disturb the formation of the actin-myosin cross-bridge.[4]

Treatments

There is conflicting research in terms of treatments of muscle soreness.[citation needed]

Stretching and muscle soreness

Stretching immediately before or after a workout does provide some help, but is not significant enough to be considered as a preventative measure.[5]
