Prolong your life by increasing your muscle power

Not all weight lifting produces the same benefit.

A recent study presented today at EuroPrevent 2019, a congress of the European Society of Cardiology, suggested that the ability to lift weight could lead to a longer life.

Study author Professor Claudio Gil Araújo, director of research and education, Exercise Medicine Clinic – CLINIMEX, Rio de Janeiro, Brazil said, “Rising from a chair in old age and kicking a ball depends more on muscle power than muscle strength, yet most weight-bearing exercise focuses on the latter. Our study shows for the first time that people with more muscle power tend to live longer.”

Power relies upon the ability to create force and velocity, and to coordinate movement.2 at the end of the day, it is the proportion of the work performed per unit time (constrain times to remove); more power is produced when a similar measure of work is finished in a shorter period or when more work is performed amid the equivalent period.3 Climbing stairs requires power- the faster you climb, the more power you need. Holding or pushing a heavy object (for instance a vehicle with a dead battery) needs strength.

Professor Araújo said, “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.”

“Muscle power gradually decreases after 40 years of age. We now show that power is strongly related to all-cause mortality. But the good news is that you only need to be above the median for your sex to have the best survival, with no further benefit in becoming even more powerful.”

Almost 3,878 non-athletes aged 41-85 years were involved in the study. All the participants have had underwent a maximal muscle power test using the upright row exercise between 2001 and 2016. The average age of participants was 59 years, 5% were over 80, and 68% were men.

The most noteworthy esteem accomplished after a few endeavors with increasing loads was viewed as the maximal muscle power and expressed in respect to body weight (for example control per kg of body weight). Values were divided into quartiles for survival analysis and analyzed independently by sex.

Amid a middle 6.5-year follow-up, 247 men (10%) and 75 women (6%) died. Middle power values were 2.5 watts/kg for men and 1.4 watts/kg for ladies. Members with a maximal muscle power over the middle for their sex (for example in quartiles three and four) had the best survival. Those in quartiles two and one had, separately, a 4-5 and 10-13 times higher risk of dying as compared to those above the median in maximal muscle power.

Professor Araújo noted that “this is the first time the prognostic value of muscle power has been assessed. Previous research has focused on muscle strength, primarily using the handgrip exercise. The upright row exercise was chosen for the study because it is a common action in daily life for picking up groceries, grandchildren, and so on. The researchers are currently examining the link between muscle power and specific causes of death including cardiovascular disease and cancer. Doctors should consider measuring muscle power in their patients and advise more power training.”

How to train to increase your muscle power:

  • Choose multiple exercises for the upper and lower body
  • Choose a weight with the load to achieve the maximal power (not so easy to lift and not so heavy that you can barely lift it)
  • Do one to three sets of six to eight repetitions moving the weight as fast as possible while you contract your muscles (slow or natural speed in returning to initial position)
  • Rest for 20 seconds between each set to sufficiently replenish the energy stores in your muscles to start the new set
  • Repeat the above for the other exercises (biceps curl, etc.).

How to progress:

  • Start with six repetitions in each set and when the exercise becomes easy, try to increase to eight
  • If it becomes easy again, increase the weight and go back to six repetitions
  • If you are unable to complete the repetitions with the proper technique, avoid “cheating” and go back to fewer repetitions or less weight. This is important to prevent injuries.
