Analysis of physiological fitness among Vietnamese elite female road cyclists

Abstract

The present study aimed to evaluate the endurance physiological characteristics of four national-level female road cyclists. The assessment was conducted at the end of the preparation phase, during the second phase of the 2021 annual training plan. Various aerobic and anaerobic physiological indicators were measured to provide insights into their performance capabilities. Aerobic physiological indicators were examined, including LT1 (lactate threshold 1) at 2.88±0.4 mmol, Power at LT1 at 2.83±0.21 W/kg, and HR at LT1 at 146.25±10.36 bpm. Additionally, LT2 (lactate threshold 2) was determined at 4.70±0.51 mmol, Power at LT2 at 4.29±0.14 W/kg, and HR at LT2 at 164±3.37 bpm. The maximal oxygen consumption (VO2 max) was found to be 67.41±2.31 ml/kg/ph. Resting heart rate (RHR) and maximum heart rate (Max HR) were 49.25±0.96 bpm and 182.5±6.86 bpm, respectively. Furthermore, the study explored anaerobic physiological indicators, including Max LA (maximum lactate accumulation) at 13.69±1.89 mmol, FI (fatigue index) at 56.37±2.51%, 5 seconds peak power at 16.68±2.88 W/kg, and 30 seconds peak power at 9.5±1.23 W/kg. These indicators collectively suggest efficient energy utilization and a strong aerobic foundation, critical for sustained performance during long-distance road cycling events.
