Supervised exercise training significantly improves walking distance for intermittent claudication patients long-term. Benefits observed at 12 weeks are sustained up to three years.

Area of Science:

  • Vascular Medicine
  • Rehabilitation Science
  • Exercise Physiology

Background:

  • Intermittent claudication (IC) significantly impacts quality of life.
  • Limited evidence exists on the long-term efficacy of supervised exercise for IC.

Purpose of the Study:

  • To evaluate the long-term outcomes of supervised exercise training (SET) in patients with intermittent claudication.
  • To assess the durability of exercise benefits up to three years post-intervention.

Main Methods:

  • Prospective study of 202 patients with IC undergoing 10 weeks of twice-weekly SET.
  • Measurements included Actual Claudication Distance (ACD), Maximum Walking Distance (MWD), and ankle-brachial pressure indices (ABPI).
  • Follow-up extended to three years.

Main Results:

  • SET led to significant increases in median ACD (237%) and MWD (242%) at three months (p<0.001).
  • These improvements were sustained at three years, with median ACD and MWD showing 223% and 188% increases, respectively (p<0.001).
  • No significant changes in ACD or MWD were noted between three months and three years; ABPI remained stable.

Conclusions:

  • Supervised exercise training offers sustained long-term benefits for patients with intermittent claudication.
  • The positive effects on walking distance achieved after 12 weeks of training persist for at least three years.
