Relying on "gut feeling" is not enough to train an athlete at the competitive or professional level. Whether you are coaching a school first team in Gauteng or training clients in a local gym, data is your most powerful tool. However, you don't need a fancy laboratory to start using performance tracking metrics effectively.
The goal of tracking is simple: to see if your training plan is actually working and to make informed adjustments before progress stalls or injuries occur. Here are the key metrics that every fitness professional should be monitoring.
To understand progress, you must record what was actually done.
Tracking these allows you to ensure you are following the principle of progressive overload without spikes that lead to burnout.
Two athletes can do the exact same workout, but one might find it easy (ranking it at 3/10) while the other finds it maximal (ranking it 9/10). By asking your athlete for their rate of perceived exertion (RPE) 30 minutes after a session, you gain insight into how their body is actually responding to the stress.
While "the scale" doesn't tell the whole story, tracking metrics like waist circumference or body fat percentage (via skinfold calipers) provides essential data on how nutrition and training are affecting an athlete’s physical makeup.
Training only works if you recover from it. Measuring simple metrics like resting heart rate (RHR) or a having the athlete complete a wellness questionnaire (rating sleep, stress and muscle soreness on a scale of 1 to 5) can alert a coach that an athlete is under-recovered.
Every 4 to 8 weeks, you should run a "test" session. This could be a single lift at maximum wight (1RM or one-repetition maximum) in the back squat, a 2.4km time trial, or a vertical jump test. These benchmarks should provide evidence that the programme is delivering results.
The secret to performance tracking isn't the collection of data but rather the interpretation. If an athlete's performance benchmarks are dropping while their RPE is rising, they are likely overtrained and need a "deload" week.
Learning to measure and manage these variables is what separates a "trainer" from a "sports scientist." If you want to master these techniques, UPOnline's Higher Certificate in Sports Sciences offers a comprehensive look at how to use testing and measurement to support athlete development. If you have not already done so, you can begin your application here and request more information from our applications team.
Start with the "big three": training volume (what you did), session RPE (how hard it felt), and one performance benchmark (such as a timed run or a specific lift).
Not at all. While heart rate monitors are helpful, some of the most validated sports science tools - like RPE scales and wellness questionnaires - require nothing more than a pen and paper or a basic spreadsheet.
Testing too often causes fatigue, but testing too rarely leaves you in the dark. A testing week every 6 to 8 weeks is generally the standard for most development programmes.
The curriculum includes modules on testing and measurement, which teach you exactly how to conduct field tests, record data accurately, and use those results to write better training programmes.
Yes. Performance tracking is highly motivating for general fitness or weight loss clients. Seeing their "strength volume" go up or their "resting heart rate" go down provides proof of health improvements that merely weighing themselves on a scale might miss.
