QUESTION 4

True or false? Moderate exercise boosts natural immune functions and host defenses for up to several hours.

True

False

Expert Solution

True

Explanation:

Moderate exercise has the following benefits:

Increase the anti-microbial activity of macrophages and neutrophils. There is an increase in the oxidative burst and phagocytic activity
Increase circulation of immunoglobulin, anti-inflammatory cytokines
Increase levels of natural killer cells, immature B cells, and cytotoxic T cells
Acute bouts of exercise increase the activity of natural killer cells and CD8-T cells. These cells have a high cytotoxic potential
Moderate exercise leads to the release of IL-6 which is anti-inflammatory
The glucose and lipid levels are under control.
Moderate intensity exercises are known to reduce the level of saliva secretion but increase the level of IgA. This improves local immunity.
Reduce the incidence of upper respiratory tract infection
Moderate-intensity exercise is known to boost the immune response to vaccines (influenza vaccine)
In a study done in the elderly, it has been found that there was an increase in the CD4+, CD28+CD4+ in those engaged in moderate-intensity exercise. This could help reduce the risk of infection and promote immunity.
