Paper

Abstract

Dietary nitrate (NO3-) supplementation has been shown to improve skeletal muscle contractile function and reduce fatigue, potentially due to alterations in skeletal muscle Ca2+ handling/sensitivity. Since aging muscle can have impaired Ca2+ handling, the aim of the study was to evaluate the effects of dietary NO3- supplementation on muscle contractile properties in young and older adults.

Research summary

Short-term dietary nitrate supplementation enhances muscle contractile properties in older adults. The study addresses a potential intervention to improve muscle function in aging, which is directly related to the aging process and its effects on physical capabilities.
