Summary
The AC test effectively measures cardiac function during exercise. This study validates the AC test
Area of Science:
- Cardiology
- Exercise Physiology
Background:
- The AC test assesses heart rate response to submaximal exercise.
- Previous studies applied the AC test to diverse populations.
Purpose of the Study:
- To present results from a reference group of healthy male students.
- To evaluate the AC test's utility in clinical settings.
Main Methods:
- Applied the AC test to 20 healthy male students.
- Measured heart rate (fh) response and recovery.
- Calculated the AC value using a specific formula.
- Estimated VO2 max using the Astrand test.
Main Results:
- Average heart rate increase was 5.32 beats/min per 10 W step.
- Average heart rate recovery time was 201 ± 82 s.
- Average hemirecovery time was 38.5 ± 15 s.
- Mean AC value was 131 ± 26.
- Mean VO2 max was 35 ± 6 ml/kg·min.
- Significant linear correlation found between AC test and VO2 max.
Conclusions:
- The AC test provides reliable data on heart rate dynamics during exercise.
- A significant correlation exists between the AC test and VO2 max.
- The AC test demonstrates value in clinical ergometric investigations.
