In this blog Professor Greg Whyte introduces the science of ageing and how targeted exercise and nutrition is required to reduce the rate of age-related decline in performance. By adopting a ‘healthy lifestyle’ we have the ability to slow the rate of aging (and potentially reverse aging for those that have lived a less than healthy lifestyle!).
Aging is not solely a matter of chronology, it is also intimately associated with biology. As we age our bodies change in response to a host of stimuli (or lack thereof!) leading to a reduction in peak performance. The rate of decline in performance (and health) is, in part, in our own hands and closely linked to changes in behaviour.
In general, a large number physiological changes occur as a result of aging including: a reduction in cardiac output (important for, amongst other things, aerobic capacity); decreased elasticity of lung structures; reduced muscle mass, strength, flexibility and mobility; glucose intolerance; and insulin insensitivity (diabetes in common in the elderly), to name but a few! Combined, these age-related changes lead to a reduction in physical performance that we commonly see starting from a peak in our mid-30’s.
Several biological ‘theories of aging’ have been proposed which can be summarized into 2 categories. Firstly, the accumulation of damage to informational molecules, and secondly, the regulation of specific genes. In other words, the repair of our cells cannot keep pace with the rate of damage throughout life leading to aging, and/or the role of specific genes is to switch-off or reduce the replication of cells leading to aging.
But, all is not lost! In addition to our genes, our environment (i.e. diet, physical activity etc.) plays a central role in the rate of aging. By adopting a ‘healthy lifestyle’ we have the ability to slow the rate of aging (and potentially reverse aging for those that have lived a less than healthy lifestyle!).
Exercise and diet have a key role to play in aging.
Numerous studies have demonstrated that the rate of the age-related decline in physical performance can be slowed significantly with targeted exercise. For example, strength and power training becomes increasingly important to combat the age-related reduction in muscle mass and strength.
Targeted nutrition is required to support the changing demands of aging (i.e. quality, quantity and timing of protein ingestion plays a central role in muscle mass and strength for older athletes).
As we age it is important that we pay greater attention to our exercise and diet to ensure we optimize our performance. Commonly, master’s athletes adopt the same practices as those of young athletes, to their detriment. The consumption of excessive sugars and inadequate protein combined with a focus on age-inappropriate training programmes are common mistakes made by master’s athletes.
In this series of blogs, along with the team at Elivar, I will be addressing some of the key nutrition areas that should be adapted for the older athlete to ensure optimum performance and health.

NMN supplements are believed to be a promising solution to increase NAD+ levels and improve cellular function. Studies have shown that NMN supplementation can improve cardiovascular function, enhance muscle function, and reduce insulin resistance. Additionally, NMN may help protect against DNA damage and inflammation, both of which are key factors in aging.
As we transition out of winter and into spring, our immune system can be vulnerable to attack. The changing temperatures, pollen, and other environmental factors can weaken our natural defences and make us more susceptible to illness.
That's why it's crucial to take steps to support your immune system during this time of year. And one of the best ways to do that is by incorporating CurraNZ Immune Support into your daily routine.
Elivar is delighted to be working with the UK Running Events Team to bring sustained release energy gels to the Trail Running community.
First Up for 2023 was the Winchester Off-Road Half Marathon.
UK Running Events host the South's most scenic Trails Runs. With distances from 5Km to Half Marathon there is something for Trail Runners of all experience levels.
