Dynamic-Express is the first and only computer-based, fully automated system for the quantitative assessment of physical fitness levels based on spectral analysis of R-R interval variability during exercise. This system can be used for the fitness evaluation of professional athletes, as its sophisticated algorithms can objectively evaluate fitness levels and detect overtraining in a precise and highly reproducible manner.
Dynamic-Express uses a convenient “Zephyr” strap with a Bluetooth transmitter to collect R-R interval variability data for analysis. The evaluation is performed during exercise on a bicycle ergometer or treadmill and takes approximately 25 to 30 minutes to administer. The results of the analysis are presented in a user-friendly interface, are conveniently stored in the client database, and can be printed at any time.
Fitness evaluation by Dynamic-Express is based on the analysis of two parameters:
1. Physical reserve level, which incorporates information regarding chronotropic myocardial reaction, exercise intensity, and length of the short recovery period. The short recovery period is calculated as the time at which R-R intervals reach 72% of the individual’s baseline.
2. Dynamic ability level, which is based on the functionality of all regulating mechanisms involved during the workout and evaluated as the long recovery period. The Dynamic-Express system utilizes a new approach for assessment of the long recovery period by determining the time at which all regulatory mechanisms, including autonomic regulation, return to the individual’s baseline.
