Why do athletes get sick so often?

Why do athletes get sick so often?

The harder and more often you train, the bigger the strain on your immune system. A compromised immune system makes you more susceptible to common bugs being passed around.

Upper respiratory illness accounts for 35-65% non-injury-related presentation to a sports medicine clinic. In athletes, upper respiratory symptoms (URS) are most often related to common respiratory viruses, viral reactivation, allergic responses to aeroallergens and exercise-related trauma to the integrity of lung membranes.

Recurrent and/or persistent respiratory illness negatively impacts the health and performance of athletes and preliminary studies show a pro-inflammatory response and a dysregulated anti-inflammatory cytokine (chemical) response to intense exercise as a possible mechanism of respiratory inflammation.

Dietary supplementation with probiotics and selected antioxidants can reduce the incidence or severity of URS in some athletes.

What is DOMS?

What is DOMS?

Delayed-onset muscle soreness (DOMS) is a type of ultrastructural muscle injury. It manifests from eccentric or unfamiliar exercise and includes reduced force capacities, increased painful restriction of movement, stiffness, swelling, and joint dysfunction. Although DOMS is considered a mild form of injury, it is one of the most common reasons for compromised sportive performance.

Biopsy analyses of muscles have revealed ultrastructural lesions which cause further apoptosis and inflammation [8, 9].

In a recent study, healthy control subjects tested the effects of curcumin (400 mg/day) before and after participating in exercises designed to induce muscle soreness. Curcumin supplementation resulted in significantly smaller increases in local proinflammatory chemicals following exercise compared to the placebo. This may help to decrease recovery time and improve performance during subsequent exercise sessions.
