Exercise Your Arms To Beat Leg Pain, Study Says
Scientists at Sheffield
Hallam University have discovered that simple arm exercises could help
beat a crippling leg condition that affects one in twenty people over
55 in the UK.
The team, along with staff
at the University of Sheffield, has found that upper body aerobic
exercise can help the battle against peripheral vascular disease (PVD),
a blood circulation problem, which causes severe leg pain and leaves
patients struggling to walk even short distances.
This is the first
large-scale trial of its kind to show that a regular workout of the
upper body can help ease the chronic leg pain associated with PVD. The
British Heart Foundation-funded study found that exercising the upper
body by 'arm-cranking', stationary cycling using the arms, improved
cardiovascular fitness over a 24-week period and enabled patients to
walk for longer without experiencing pain.
The findings are a boost
for patients with PVD, who can find even moderate walking exercise
difficult and may require surgery in severe cases.
More than a hundred
patients with PVD aged between fifty and 85 were recruited from the
Sheffield Vascular Institute at the Northern General Hospital.
Pain tolerance levels were
measured in a series of walking tests at six-weekly intervals and the
total improvements were calculated at the end of the 24 weeks. The
average maximum walking distance increased by nearly a third (29 %),
equal to an extra one hundred metres. Patients could also walk for
fifty per cent longer before the onset of leg pain.
John Saxton, from Sheffield
Hallam University's Centre for Sport and Exercise Science, which
conducted the study with the University of Sheffield's School of
Medicine and Biomedical Sciences, said:
"The cardiovascular
function and walking ability of the patients with PVD who took part in
the arm exercise programme both improved. The onset of leg pain was
delayed during walking, and they were able to push themselves further
beyond the pain barrier to achieve improvements in maximum tolerable
walking distance. Our results suggest that a combination of
physiological changes and an increase in exercise pain tolerance
account for the observed improvement in walking ability."
"The advantage of
exercising the arms for patients with PVD is that they don't generally
encounter pain during this type of physical activity. This can help to
increase their motivation and enthusiasm for exercise. A reduced level
of physical activity potentially contributes to subsequent disability
and increases the risk of cardiovascular problems occurring."
Peripheral vascular disease
occurs when the arteries narrow or become blocked with fatty material.
The artery can become so narrow that it can't deliver enough
oxygen-containing blood to the legs during walking exercise. This
results in leg pain known as intermittent claudication and forces the
person to stop and rest until it passes.
Smoking, diabetes, high blood pressure and a poor diet are high risk factors.
The study was recently
published in the Journal of Vascular Surgery, a leading international
scientific journal for this field of research.
