Athlete Performance: Measurable Assessment, Workload, and Injury Risk Management
Athlete performance cannot be reliably measured with a single “energy scan,” device printout, or app, nor can it be guaranteed to increase by a specific percentage. In professional or recreational athletes, the correct approach is to evaluate sport-specific performance goals, health status, training load, recovery, and injury history together.
In which areas do we evaluate performance?
In the current sports medicine approach, physical fitness is not one-dimensional. Depending on the clinical context, the appropriate areas from the following are measured:
- Cardiorespiratory capacity: VO₂max/VO₂peak or appropriate field tests, heart rate response, and recovery.
- Muscle strength and power: dynamometry, functional strength tests, sport-appropriate power and endurance measurements.
- Body composition: BIA under appropriate conditions, anthropometry, or more referential methods when needed.
- Neuromotor performance: balance, coordination, agility, and sport-specific movement quality.
- Flexibility and joint range of motion: targeted assessment based on the sport and existing injury risk.
- Sport-specific performance: the sport’s actual performance indicators, such as speed, sprint, jumping, power, technical skill, or endurance.
How is training load monitored?
Training load is not merely the amount of work performed. The external load and the athlete’s internal response to this load are evaluated together. Indicators that can be used include training duration/distance, power or speed data, heart rate, rating of perceived exertion (RPE), sleep, recovery, and symptoms.
No single metric can definitively predict an injury. The goal is not to “find the future injury,” but to make the program safer by identifying rapid load changes, inadequate recovery, previous injuries, and sport-specific risks early on.
What is more important in reducing injury risk?
- a sport-appropriate progressive strength and conditioning program,
- neuromuscular warm-up and movement training,
- eccentric muscle strengthening when needed,
- monitoring the workload–recovery balance,
- adequate energy and protein intake,
- improving sleep duration and quality,
- adequate rehabilitation of previous injuries and return-to-sport criteria.
The role of BIA and “energy/frequency scanning”
Bioelectrical impedance analysis can be used under appropriate conditions to track body water and estimated body composition. However, it is not a method that independently diagnoses disease, future injury, occult inflammation, allergy, or the cause of a decline in performance.
We do not use “energy,” “meridian,” “organ stress,” or similar values obtained from bioresonance or electrodermal systems as validated biomarkers predicting performance enhancement or future health problems. If available, these are evaluated only as complementary/exploratory data.
Medical causes of performance decline
In unexpected performance loss, focusing solely on the training program may not be sufficient. Depending on the clinical condition, iron deficiency/anemia, infection, thyroid disorders, low energy availability, sleep disorders, asthma, cardiovascular issues, overtraining/inadequate recovery, and drug effects should be evaluated.
Supplements and IV applications
Supplements or IV applications are not routinely initiated as a “performance package.” First, genuine deficiency, nutritional adequacy, renal/hepatic functions, medications used, and anti-doping rules are evaluated. Performance improvement is not guaranteed.
Our approach in our Bodrum clinic
Our goal is to measure the athlete’s true performance indicators, identify modifiable risks, and collaborate when necessary with sports medicine, physical therapy, or relevant specialties. Rather than the printout of a device, the change across serial measurements and the athlete’s actual function are what matter.
