Here is part 2 of Methods for Record Keeping:
1. Medicine Ball/Weight Throws for Distance: There are many variations of throws you can do here, such as behind the back, forward push toss, granny toss, and side tosses.
2. Jumping Movements: Standing Broad Jump, Vertical Jump (Vertec or Jump Mats).
3. Body Mass and Body Composition: This can be especially important for sports that adhere to weight classes, but is still an important measure for any sport.
4. Short Sprints: Most sports require short bursts of explosiveness, so 20 meter and shorter linear sprints can be a good performance marker.
5. Agility Tests: Some agility tests are better than others, but an agility drill specific to the athlete’s sport can be a good indicator of agility improvement.
6. Sport Specific Testing: One baseball test I learned of recently is to track initial ball velocity when hit off of a tee. You can’t get much more specific to a sport than a test like that.
7. Statistical Process Control: This is a method of establishing “normal” values of a variable for a specific athlete. For example, one method might be to track daily waking heart rate. Heart rates that are seen outside of about 1 standard deviation of the average may indicate something worth looking at. One company has a system for this up and running: Sportably.com
