Aerobic Capacity: The Hidden Injury Risk

Aerobic Capacity: The Hidden Injury Risk

acl injury prevention

Do you, your kids, or grandkids play sports? If you do, you probably know that aerobic fitness can help improve performance. But did you know that aerobic fitness, specifically aerobic capacity is also important to avoid injury?

There’s a lot of research that shows that lower aerobic capacity is associated with a higher risk of injury. Aerobic capacity, is most frequently measured by VO2 max, either in a lab or a field test.

Lower Aerobic Capacity Increases Injury Risk

You can see in the video below the results of a 2017 study of female adolescent soccer players. Players with lower VO2 max had a higher risk of having 2 or more injuries during a season. When the P= .05 or less, it indicates a significant difference.

You can see the other interesting finding: lower VO2 max was also associated with a higher incidence of illness during the season.

The important take away here is that training to increase VO2 max can help you avoid injury and illness. If you’re not injured but starting to play sports or recovering from an injury, you need to train this.

How You Can Train Aerobic Capacity (VO2 max)

There is more than one way you can do this. Aerobic training is primarily prescribed based on % of maximum heart rate (HR max). Some research shows that training for 20 to 30 min at 60% to 70% of HR max can increase VO2 max if you’re untrained.

However the research is clear that high intensity interval training (HIIT) works best if you’re healthy, overweight/obese or athletic. There are 2 different strategies.

Strategy 1

  • Short work interval (≤30 seconds of work per interval at 85% to 95% of HR max)
  • Low-volume (≤5 min of total work/session)
  • Example: 30 seconds of work, followed by 30 seconds of rest for a total of 10 rounds.

This strategy is time-efficient and highly effective for improving VO2 max, especially for the general population. You can see VO2 max improvements with as little as 4 weeks of training.

Strategy 2

  • longer interval (≥2 min of work per interval at 85 to 90% of HR max)
  • higher volume (≥15 min of work/session)
  • Example: 3 min of work followed by 3 minutes of rest for a total of 5 rounds

This strategy requires more time, but you can see greater improvements in VO2 max.

With either strategy 2 times a week is enough to see good improvements. Doing more than 3 times a week is probably going to take time away from other things you could be training without much gain in VO2 max.

In either case, if you’re not used to aerobic exercise, building a baseline of aerobic fitness in the 60% to 70% is a good place to start. You’ll see some initial gains in VO2 max and you need to train this energy system too.

If you’ve built a good base in the 60% to 70% HR zone, then HIIT training can help get you the rest of the way to your goals.
