ABSTRACT
Physiological changes which affect fluid needs should be considered in advice on hydration for the older athlete. Masters athletes may have a decreased thirst perception, reduced kidney function and altered thermoregulatory mechanisms. Supplement use is common among athletes at all levels; however, type and reasons for use may be different for masters athletes versus their younger counterparts. Nutrition recommendations for the general population consider the physiological effects of ageing and should be used as a basic framework to map dietary plans of masters athletes. Calcium and vitamin D supplementation may be taken, particularly by female masters athletes, to improve bone health; however, dietary sources of these nutrients are also available. Masters athletes may take vitamin and mineral supplements for the health benefits of some nutrients within a restricted energy budget; however, overconsumption of some nutrients could be harmful.
