MEASURING PRACTICE EFFORT

This fifth issue of Coaching Science Abstracts reviews articles concerned with measuring training effectiveness.

There is a strong trend today to assess the impact of training. Three common indexes, lactate accumulations, heart rates, and perceived exertion, are generally used without question. For sports that are aerobically oriented, anaerobic threshold is used as the criterion for training benefits. However, these measures may not be as valid or reliable as is often assumed.

The main question that should be asked by a coach or athlete when requested to complete a measurement or test is, how relevant is it for measuring what occurs in the sport?

A discussion about the utility of a measure could continue ad infinitum. The principal concern of any coach or athlete should be that if something is measured, what extra information does it add to the perceptions of the coach and athlete so that better coaching decisions can be made. Testing for testing-sake, does not serve a worthwhile purpose. Unless a measurement about an aspect of an athlete's performance can be related to the total performance, it may not be very useful. In the complexity that is an athlete, a single factor has to be considered in light of its interaction with the myriad of other factors that govern performance. If that is not done, then the considerations used to make coaching decisions may not be sound because they would be too limited.

Measuring practice effort is intended to provide glimpses of what is said about frequently used measures of the training response.
