Adaptations to Training
When we “use” our bodies, our bodies adapt to the activity we are doing. The more we do, the more we are able to do. The less we do, the less we are able to do. This is essential in eliciting a training response.
When we train we want to cause stress to our body. (This may be our muscles, bones, cardiovascular system, etc.) We want to overload the system, which causes a degree of damage or micro-trauma. The body then responds by growing bigger / stronger / faster / fitter, so it can cope with that load in future. We cause stress to force adaptations.
Stress/load => damage => rest/recovery => adaptation/growth.
A lot of common gradual-onset injuries result from a failure to adapt to load.
There are a number of variables that can be multiplied to determine the total load:
The intensity of the activity is the most powerful multiplier in this list.
When we are considering total load, we also need to consider variables that make it harder for our bodies to adapt to load.
Variables that can be multiplied to determine how well we adapt to the load:
Recent research found that getting less than 8 hours sleep a day almost doubles the injury rate in athletes.
