The effects of nitrate have also been shown to be influenced by age. It has been documented that there are alterations in NO metabolism in older adults thought to result from impairment of the NO-synthases pathway. The investigators have shown that consumption of a supplement high in nitrate, such as beetroot juice, leads to elevated plasma nitrite levels and may help restore NO metabolism in older adults; whereas a diet high in nitrate without supplementation was insufficient at increasing plasma nitrite levels. The investigators research, along with that of others has shown nitrate supplementation to have positive effects in older adults with chronic diseases. However, research examining the effects of dietary nitrate on exercise performance in healthy older adults is scarce. Presently, it is unclear as to whether nitrate supplementation is beneficial to exercise performance in older adults and there is no data examining the effect of nitrate supplementation on exercise performance in active older adults. Therefore, the purpose of this study is to examine the effect of chronic nitrate supplementation on exercise performance in active higher functioning older adults.
