Regular readers of t his blog will know how much I value monitoring training/matches. Heart rate monitors, GPS units, video analysis, and RPEs can all be used to quantify the volume and intensity of training. My own research for my PhD centers around this subject.
Something that I have not really written about, however, is the importance of monitoring other aspects of the athlete's life. We as coaches work with our athletes 1 to 4 hours per day. What they do for the other 23 to 20 hours per day has a huge impact on the all important process of recovery & adaptation.
Outside stressors can range from lack of sleep, family problems, inadequate nutrition, and stress.
Outside Stressors (from Stone, Stone, & Sands, 2007)
We are all in this industry (I hope) to help our athletes improve. Having some method of tracking outside stressors will help them move towards their goals. On a selfish front - we can create an excellent training program for our players but if they are doing the wrong things away from the field and gym, then our program may well not seem so good. If the athlete is going through some hard times (relationship break-up, illness of a family member, etc.), then we probably should modify training otherwise performance may suffer and/or injury could be more likely.
