I was very surprised that very few parents and coaches conduct constant control of their tennis players health condition in US. However, I am also not that surprised because I see that there is no regular system regarding control of junior sportsmens health.

I don't know about a situation with that in the United Kingdom. 

In America, I have never heard of tennis players who play for 25 and more hours a week at a tennis academy and have regular medical control of their health, including biochemical blood tests and other routine tests which are very common for any junior sportsman in many European countries. My son did those tests and had a medical evaluation in a specialized sports clinic two times a year.

Whats important to understand is that Sports medicine possesses a huge deal of knowledge that regular physicians are not aware of.

If your junior tennis player trains for more than 10 hours a week and participates in tournaments on regular basis, then you are supposed to organize some kind of special medicine control for his health.

Ive never witnessed a situation where a coach tells his player to get a two-three week break from tennis for active rest or suggest a blood test that shows a players condition. Maybe I am wrong and some tennis coaches definitely do that, but most ones do not.

There are some simple methods, such as the Rufe index, which are easily applied to self-control of the very important system of the body the cardiovascular system. You may do it on constant basis and use its results to plan training cycles for your kid or as a reason to visit a cardiologist or a sports medicine doctor.

There is a fast method for control of the junior tennis players condition. It is called the Rufe index. It analyzes the condition of heart activity during training.  When I was a junior and college sportsman, we always used the method for estimating the current physical condition. It shows you how your organism performs with current training. It shows if an organism is overtrained, if there is a necessity for rest and recovery, as well as indicating other problems with the cardiovascular system of a junior sportsman.

All measurements are conducted in 15 seconds intervals.

1.    Sit down and rest for five minutes. Then measure your pulse in 15 seconds.  It is P1.

2.    Do twenty sits-up in 30 seconds and immediately measure your pulse in 15 seconds in standing position. It is P2.

3.    After that, sit down and after one minute rest, measure your pulse in 15 seconds again.
Formula for getting the result is: J= (4 X (P1+P2+P3) - 200)/10.

If J is less than 0, present adaptation for your training is excellent,
Less than 3 very good,
3-5 good,
6-10 satisfactory,
11-15 weak,
15 and more unsatisfactory. Go to the doctor immediately.
Increase in the value of J shows overtraining conditions.

For example if your P1 is 15, P2 is 25 and P3 is 20.

For you J is (4 x (15+25+20) - 200)/10 = 4.
It means that your current condition is good and your body performs well under your current training program.
