MAXIMAL OXYGEN CONSUMPTION AND PERFORMANCE IN A CENTENARIAN CYCLIST – 2017


Veronique Louise Billat1,*Sophie Besse ET AL
PURPOSE
– Examine the physiological characteristics of an elite cyclist who, at 101 yrs, established the 1 hr cycling record for individuals ≥ 100 years old (24.25 km)
– Determine the physiological factors associated with his performance improvement 2 years later at 103 years old (26.92 km; +11%).
METHOD
– Before each record, he performed an incremental test on a cycling ergometer
– For 2 yrs, he trained 5,000 km/yr with a polarized training that involved cycling:
(1) 80% of mileage at “light” rate of perceived exertion (RPE) ≤12
(2) 20% at “hard” RPE ≥15 at a cadence between 50 and 70 rpm.
RESULTS
1. His bodyweight and lean body mass did not change, while his ⩒O2max increased (31 to 35 ml.kg-1.min-1; +13%)
2. Peak power output increased from 90 to 125 W (+39 %), mainly due to increasing maximal pedaling frequency (69 to 90 rpm; +30%)
3. Maximal heart rate did not change (134 to 137 bpm) in contrast to the maximal ventilation (57 to 70 L.min-1, +23%), increasing with both the respiratory frequency (38 to 41 cycle.min-1; +8%) and the tidal volume (1.5 to 1.7 L; +13%)
4. Respiratory Exchange Ratio increased (1.03 to 1.14) in the same extent as tolerance to ⩒CO2
CONCLUSION
– It’s possible to increase performance and ⩒O2max with polarized training focusing on a high pedaling cadence even after 100 yrs
NEW & NOTEWORTHY
1. Maximal oxygen consumption (+13%) and performance (+11%) can be increased between 101 and 103 yr old with 2 yr of training
2. A centenarian is able, at 103 yr old, to cover 26.9 km/h in 1 hr
