The role of strength training in
cardiac rehabilitation
Skeletal muscle is the primary tissue for glucose and
triglyceride metabolism and a determinant of resting
metabolic rate. Therefore, increase in muscle mass
reduces multiple CAD risk factors. Cross-sectional
studies have shown that muscular strength is inversely
associated with all-cause mortality and the prevalence
of metabolic syndrome independently of aerobic
fitness levels.
Furthermore, increased muscle mass can improve the
individual’s ability to become more physically active,
raise the basal metabolic rate, and in older people,
improve the ability to perform activities of daily living,
decrease fall risk, and increase the quality of life.
Both research findings and clinical experience indicate
that strength exercise is safe for stable CAD patients.
For patients at moderate to elevated risk of adverse
cardiac events, strength training can be safely
undertaken with proper preparation, guidance, and
surveillance.
