Summary

Aero style handlebars did not significantly impact time to exhaustion or exercise intensity in trained cyclists during long-term cycling. Performance metrics remained comparable between aero and standard racing handlebars.

Area of Science:

  • Sports Science
  • Exercise Physiology
  • Biomechanics

Background:

  • Aero style handlebars are increasingly popular in cycling disciplines like triathlons and time trials.
  • Previous research on aero handlebars has primarily focused on short-term exercise effects.
  • The impact of aero handlebars on prolonged endurance performance remains less understood.

Purpose of the Study:

  • To compare time to exhaustion between aero and standard racing handlebars during long-term cycling exercise.
  • To evaluate differences in ventilation, gas exchange, and pulmonary function with aero versus standard handlebars.
  • To assess the influence of handlebar type on endurance cycling performance.

Main Methods:

  • Eleven highly trained cyclists (VO2max: 61.7 ± 2.9 ml.kg-1.min-1) participated in two continuous cycling rides.

  • Rides were performed on a Velodyne trainer at 80% VO2max, increasing intensity every 15 minutes.
  • Subjects used either aero style or standard racing handlebars, with performance and physiological measures recorded.

    • Main Results:

    • Time to exhaustion was 69.3 ± 5.3 minutes with standard handlebars and 59.8 ± 7.0 minutes with aero handlebars (not statistically significant).
    • Average work rates at exhaustion were 276.4 ± 39.3 watts (standard) and 268.1 ± 38.4 watts (aero), showing no significant difference.
    • Gas exchange and ventilatory parameters were measured throughout the exercise bouts.

    Conclusions:

    • Aero style handlebars do not significantly alter time to exhaustion or exercise intensity compared to standard racing handlebars in trained cyclists during prolonged exercise.
    • The findings suggest that handlebar choice may not be a critical factor for endurance performance in this population.
    • Further research could explore other physiological or biomechanical factors influenced by handlebar type.
