The scientists advised
the younger generation to involve in regular physical exercises
to strengthen their weak muscles.
The known causes of
premature deaths are high blood pressure and high body index (BMI)
involvement of muscular strength in adolescence or childhood in predicting
mortality is still not well established.
Rasmussen at the Karolinska Institute in Sweden
conducted a research studied around one million Swedish male adolescent in the
age group of 16 to 19 years for 24 years.
The volunteers had to go through three authentic muscular
strength tests namely the handgrip tests, elbow flexion tests and knee
extension strength tests. Their blood pressure and BMI were also recorded. Deaths
occurring before the age of 55 years are termed as premature deaths
The researchers noted
that around 26,145 volunteers died during the study follow-up. Suicide was a
common cause of premature death (22.3 percent) in comparison to deaths
occurring due to cancer (14.9 percent) and cardiovascular ailments (7.8
strength was seen to be associated with 20 to 35 percent decrease in risk of
observed that strong adolescents had 20 to 30 percent less chances of premature
deaths occurring from suicide and 65 percent less probability of having any
psychiatric ailment such as mood disorder and schizophrenia.
The study highlighted
the importance of strong muscles in enhancing mental strength. Individuals with
weak muscular strength were more vulnerable to mental weaknesses
According to Finn
Rasmussen and colleagues, weak muscular strength was associated with high
all-cause mortality and high mortality in cardiovascular ailments before the
age of 55 years.
The researchers said, "People
at increased risk of long term mortality, because of lower muscular strength,
should be encouraged to engage in exercise programmes and other forms of
They added that weak muscular strength in young adults is
a rising risk factor for deaths such as suicidal deaths and deaths occurring
from cardiovascular diseases.
They advocated, "The
effect sizes of these associations are similar to classic risk factors such as
body mass index and blood pressure."
concluded that good muscular strength was related with better fitness of cardio
respiratory system. Weak muscular strength should be regarded as an emergency
risk factor for premature deaths occurring in adulthood.
