Radial pulse waveform and parameters in different types of athletes

Area of Science:

• Sports Science
• Cardiovascular Physiology
• Biomedical Engineering

Background:

• Understanding the physiological demands of different sports is crucial for athlete training and cardiovascular health assessment.
• Maximal oxygen uptake (MaxO2) and maximal muscular voluntary contraction (MVC) are key indicators of athletic performance and physiological capacity.
• Radial pulse waveform analysis offers a non-invasive method to assess cardiovascular function.

Purpose of the Study:

• To classify sports events based on MaxO2 and MVC.
• To analyze radial pulse waveforms and their characteristic parameters across different sports.
• To correlate pulse waveform characteristics with athletic performance metrics.

Main Methods:

• 304 professional athletes from Beijing Muxiyuan Sports Technical School participated.
• Radial pulse waveforms were normalized for cycle and amplitude (0-100).
• Key parameters analyzed included Tm, X, Y, K, and SDPTG.

Main Results:

• Distinct radial descending curve trends were observed based on MaxO2 and MVC levels.
• Characteristic parameters (Tm, X, Y, K, SDPTG) differed significantly between MaxO2 and MVC groups.
• Pulse waveform trends varied even when MaxO2 or MVC levels were constant, indicating complex physiological interactions.

Conclusions:

• Pulse waveform trends differ between MVC (<50% vs. >50%) and MaxO2 (<40%, 40-70%, >70%) groups.
• Specific sports in group F exhibited the smallest parameter values, suggesting they are most beneficial for cardiovascular health.
• Radial pulse waveform analysis provides valuable insights into the cardiovascular adaptations to different sports.
