When it comes to injury prevention (performance enhancement), simple is always best. Here are 2 perfect examples of what happens when you dont get the basics right.
In a study of elite adolescent athletes (15-19 years) it was found that a "perfect storm" of increased training intensity, increased training load and less than 8 hours sleep per night resulted in a 2.3x greater risk of sustaining an injury (acute or overuse) compared to athletes who had no change in these variables (von Rosen et al, 2017).
Furthermore, in a study of 340 adolescent athletes, injury risk was significantly reduced in those that slept >8hrs per night (61%) and those that met nutritional guidelines (64%) - von Rosen et al (2016).
1) Kids just need to get the basics right! Keep it simple, and don't worry about the sexy.
2) Monitor training loads by using the principles of Acute:Chronic workload ratio (trying to avoid spikes in training loads), eat well and get >8hrs sleep per night.
