High-intensity interval training (HIT) significantly improved 40-km time trial performance in competitive cyclists. This 4-week program enhanced peak power output and fatigue resistance, leading to faster race times.

Area of Science:

  • Exercise Physiology
  • Sports Science
  • Cycling Performance

Background:

  • Competitive cyclists typically engage in moderate-intensity endurance training (BASE).
  • The efficacy of high-intensity interval training (HIT) as a supplement or replacement for BASE in improving performance requires further investigation.

Purpose of the Study:

  • To determine if a 4-week high-intensity interval training (HIT) program can enhance 40-km time trial (TT40) performance in cyclists.
  • To assess the impact of HIT on peak sustained power output (PPO) and muscular resistance to fatigue (TF150).

Main Methods:

  • Eight competitive cyclists with a background of moderate-intensity endurance training (BASE) participated.
  • A 4-week HIT program replaced 15% of their weekly training volume, involving six to eight 5-minute intervals at 80% of PPO with short recovery.

  • Performance was assessed via TT40, PPO, and TF150 before and after the intervention.

    • Main Results:

    • HIT significantly improved TT40 performance (P < 0.0001).
    • Peak sustained power output (PPO) and muscular resistance to fatigue (TF150) were significantly increased post-HIT (P < 0.01).
    • Faster TT40 times were attributed to significant increases in both absolute and relative power output.

    Conclusions:

    • A 4-week high-intensity interval training (HIT) program is effective in improving 40-km time trial performance in competitive cyclists.
    • HIT enhances key physiological markers including peak power output and fatigue resistance, crucial for endurance cycling success.
