Muscle power has prognostic value. For the first time, a
new study presented at EuroPrevent 2019, a scientific congress of the European
Society of Cardiology has shown that people with
more muscle power tend to live longer.
“Power training is carried out by finding the best
combination of speed and weight being lifted or moved. For strength training at
the gym most people just think about the amount of weight being lifted and the
number of repetitions without paying attention to the speed of execution. But
for optimal power training results, you should go beyond typical strength
training and add speed to your weight lifts,” says Professor
Claudio Gil Araújo, director of research and education, Exercise Medicine
Clinic – CLINIMEX, Rio de Janeiro, Brazil.
The study enrolled 3,878 non-athletes aged 41–85 years
who underwent a maximal muscle power test using the upright row exercise
between 2001 and 2016. The highest value achieved after two or three attempts
with increasing loads was considered the maximal muscle power and expressed
relative to body weight (i.e. power per kg of body weight). Values were divided
into quartiles for survival analysis and analyzed separately by sex.
During a median 6.5-year follow-up, 247 men (10%) and 75
women (6%) died. Median power values were 2.5 watts/kg for men and 1.4 watts/kg
for women.
Participants with a maximal muscle power above the median
for their sex (i.e. in quartiles three and four) had the best survival. Those
in quartiles two and one had, respectively, a 4–5 and 10–13 times higher
risk of dying as compared to those above the median in maximal muscle power.
Climbing stairs requires power, while holding or pushing
heavy objects needs strength.
Muscle power gradually declines after 40 years of age.
Most weight bearing exercises focus on building strength, but simple day to day
activities such as rising from a chair in old age require muscle power more
than muscle strength.
The study authors recommend that doctors measure muscle
power in their patients and advise more power training.
