Summary

Carrying extra weight significantly reduces walking distance in patients with intermittent claudication. Weight reduction may be crucial for managing claudication symptoms, especially in mild cases.

Area of Science:

  • Vascular Medicine
  • Exercise Physiology

Background:

  • Conservative management for intermittent claudication includes lifestyle modifications.
  • While smoking, exercise, and diet effects are known, the impact of body weight requires further investigation.

Purpose of the Study:

  • To determine the effect of carrying additional weight on maximum walking distance in stable intermittent claudication patients.

Main Methods:

  • Twenty stable intermittent claudication patients underwent treadmill testing with varying carried weights (0-10 kg) in a randomized sequence.
  • Maximum claudication distance and ankle-brachial pressure index were measured.
  • Patients were classified as mild or severe based on their baseline walking distance.

Main Results:

Related Experiment Videos

  • A significant reduction in claudication distance was observed with loads of 5 kg or more (P < 0.01).
  • A strong linear relationship (r=0.98, P < 0.01) existed between claudication distance and carried weight.
  • The response index (reduction in distance per kg) was significantly higher in mild claudicants compared to severe claudicants (P < 0.01).

    • Conclusions:

    • Carrying extra weight adversely impacts walking distance in intermittent claudication.
    • Weight reduction may be an important therapeutic strategy for managing intermittent claudication, particularly in patients with milder symptoms.
