Elevated coaching frequency can enhance VO2 max.
Final up to date on December thirteenth, 2024
Is your endurance training lagging regardless of logging countless miles on the treadmill or lengthy periods on the elliptical? Improving your conditioning isn’t as simple as prolonged durations on cardio machines. There’s extra science to it than brute power.
In early December 2024, Dr. Gommaar D’Hulst, a senior scientist at ETH Zurich, Switzerland, shared actionable methods to boost conditioning. He addressed frequent issues and outlined key ideas to enhance coaching.

Train Coaching Non-Responders
Dr. D’Hulst referenced the “Household HERITAGE Research,” an older analysis mission that examined the consequences of train coaching on genetically associated people. (1) Over 20 weeks, researchers applied progressive overload training utilizing varied exercise equipment. Findings highlighted the next variations in particular person coaching responses:
- Some contributors skilled vital enhancements of their VO2 max, an indicator of the physique’s potential to soak up and make the most of oxygen.
- Others confirmed little to no enchancment, with some experiencing a decline of their oxygen uptake, categorizing them as non-responders or low responders. Conversely, some excessive responders confirmed distinctive health features.
- Most contributors noticed a median enhance in oxygen uptake starting from 200 to 500 milliliters, representing the biggest phase of the research group.
Since this influential research, researchers have attributed these variations to human genetic variations, suggesting that some people can bear in depth coaching but obtain minimal health enhancements attributable to inherent organic components.
Research Debunked
One other research debunked that notion of genetics. The counter-study emphasised that, with correct coaching, everybody can profit from train. (2) Eighty-seven younger, wholesome people with no prior coaching participated. Baseline assessments, together with VO2 and VO2 max measurements, had been performed by an incremental check to exhaustion.
Some people who skilled as soon as, twice, and even thrice per week confirmed no enchancment of their VO2 max ranges, indicating they didn’t reply to the preliminary train routines.
Contributors within the teams coaching 4 or 5 occasions every week skilled full advantages. Researchers suggested non-responders to extend their coaching frequency by doubling their periods.
Those that initially skilled as soon as per week elevated to a few periods, whereas these coaching twice every week elevated to 4. Equally, contributors coaching thrice per week elevated to 5 periods. After relaxation, the changes considerably boosted training volume of all non-responders.
Following one other six weeks of coaching at these increased intensities, each group confirmed marked enhancements in VO2 max. This demonstrates a transparent takeaway: people can successfully improve their VO2 max over time by growing weekly coaching frequency.
What Does This Imply for Coaching?
In response to Dr. D’Hulst, functional fitness contributors who intention to boost their cardio conditioning ought to comply with the next steps:
- Observe progress persistently by performing a practical threshold energy (FTP) check, a VO2 max evaluation, and a time trial (e.g., run or row 10 kilometers each 10 to 12 weeks).
- Observe coaching quantity utilizing the TRIMP formulation (coaching impulse), calculated as charge of perceived exertion (RPE) multiplied by training duration.
- Progressively enhance coaching quantity by 10-15% by progressive overload.
Useful athletes concerned in CrossFit or HYROX who intention to extend their coaching quantity and enhance conditioning can profit from block periodization, which prioritizes a selected coaching space.
For HYROX athletes, the season may be strategically divided based mostly on competitors objectives. Early phases can deal with low-intensity, long-duration cardio conditioning to construct a robust base endurance. Because the season progresses and competitions draw close to, coaching can shift to higher-intensity efforts.
“In the event you’re combating conditioning, monitor your coaching load and up the coaching quantity in a block-periodized approach,” D’Hulst really useful. “That’s the method to go to enhance total conditioning whereas sustaining practical health.”
