CrossFit is undoubtedly the most popular training method today, partly due to the effects this activity has on the body.
CrossFit is a high-intensity workout, and as such, we might think it helps burn fat, build muscle mass, and burn a large number of calories. However, studies show that it improves aerobic capacity and increases endurance.
After 10 weeks of CrossFit training, body weight decreases between 2.6% and 3.8%, body fat percentage reduces significantly, and lean mass increases between 1.4% and 2.2%.
The Other Side of CrossFit
Since CrossFit is functional training, most would think practicing it has no risk. However, because it is a high-intensity activity, its injury rate is not low. The injury rate is estimated at 3.1 per 1000 hours of CrossFit training.
Injury rates in CrossFit are similar to those seen in Olympic weightlifting or powerlifting but are lower than in contact sports like rugby.
Once again, it is essential to prevent injuries by focusing on the technique of each exercise and adjusting the intensity to the individual's physical condition. And of course, staying hydrated during training is also key.
What science tells us about CrossFit is that it can deliver great results but requires caution to avoid overdoing it, as it is a high-intensity workout not suitable for those without prior knowledge.
