Exceptional exercise capacity in a late bloomer octogenarian triathlete

Area of Science:

• Exercise Physiology
• Gerontology
• Sports Science

Background:

• Maximal oxygen uptake (V̇O2max) declines with age, with limited data on octogenarians.
• The >80 population is rapidly expanding, increasing interest in healthy aging and physical activity benefits.
• Endurance exercise is known to benefit physical, cognitive, and psychosocial health in older adults.

Purpose of the Study:

• To characterize the V̇O2max and exercise performance of an octogenarian male triathlete.
• To investigate the relationship between training volume, intensity, and physiological markers in an elite octogenarian athlete.
• To provide insights into the potential of high-level endurance training for maintaining fitness in advanced age.

Main Methods:

• An incremental Cardiopulmonary Treadmill-Running Exercise Test (CPX) was performed.
• A 5-day consecutive triathlon event (sprint and Olympic distances) was monitored using a smartwatch.
• Training logs (10-12 hours/week) and competition data (59 in 2021, 39 in 2022) were analyzed.

Main Results:

• The subject achieved a V̇O2max of 39.8 mL·min⁻¹·kg⁻¹, the third highest reported in octogenarians, equivalent to the 60th percentile for 40-50-year-old men.
• During the 5-day triathlon (12:15 h:min total), 88% of time was spent at vigorous intensity (77-95% max heart rate).
• The subject won the 2022 Triathlon Olympic distance World Championship.

Conclusions:

• Exceptional V̇O2max and performance in this octogenarian are linked to very high training volume and intensity, exceeding guidelines by over fourfold.
• These findings support the significant benefits of sustained, high-intensity endurance exercise for maintaining peak physical function in octogenarians.
• This case demonstrates the potential for elite athletic achievement and high physiological capacity in individuals over 80.
