Strength Training

“Resistance training (RT) is the only non-pharmacological intervention known to consistently improve, and therefore offset age-related declines in skeletal muscle mass, strength, and power,” write the authors of a recent study published in the journal Sports Medicine.

But the researchers found that weightlifting and other forms of RT are not popular among our aging population, “likely due to numerous factors including time constraints, a high-perceived difficulty, and limited access to facilities and equipment.”

Benefits of Weight Training

Wayne L. Westcott, PhD, author of numerous strength-training and fitness books, estimated that inactive adults lose up to 8 percent of their muscle mass each decade.

He cited many benefits of weight training, including:

  • sharper cognition
  • diabetes prevention
  • weight reduction
  • improved physical performance
  • better cardiovascular health
  • reductions in pain...
    • in lower back
    • from arthritis

Research on Resistance Training

Research show gains in training capacity and competitive performance for runners, swimmers, cross-country skiers, and many other athletes following the addition of weightlifting to their programs.

Reduced Risk of Disease

A recent meta-analysis published in the American Journal of Preventive Medicine provided “the strongest evidence to date that resistance training is associated with reduced risk of all-cause, cardiovascular disease, and cancer-specific mortality.”

Improved Longevity

In one recent study published by JAMA Network Open, an analysis of more than 115,000 people aged 65 and older showed that no matter how much aerobic exercise people did, it was strength training at least twice a week that lowered the risk of dying.

People who did strength training twice or more a week who also did 2.5 hours of aerobic exercise saw their risk of death during the eight-year study period drop by 30 percent.

Strength Training Tips

This advice isn’t just for competitors. Nearly anyone can improve their overall fitness—and potentially add healthy years to their life—by incorporating strength training into their exercise routines.

  • Focus on Maintenance

    “Across the lifespan, declines in strength and power occur up to eight times faster than the loss of muscle mass, and are more strongly associated with functional impairments and risks of morbidity and mortality,” wrote the authors of the Sports Medicine study.

    “Strategies to maximize healthspan should therefore arguably focus more on improving or maintaining muscle strength and power than on increasing muscle mass.”

    Building big muscles needn’t be the goal.

  • Include Aerobics

    Weight training can have significant effects on balance, endurance, and overall strength, particularly in combination with aerobic exercises such as:

    • walking
    • cycling
    • gentle running
    • swimming
  • Start Small

    Working with light dumbbells can be very effective, and so can body-weight exercises such as planks and pushups.

    A small amount of resistance training can lead to major improvements with less time and effort than you might have thought.

  • Consult Professionals

    Novices should check with a healthcare professional before beginning a weightlifting program.

    Virtually every gym, YMCA, municipal recreation center, senior center, or similar establishment will have someone on the staff who can help guide a weightlifting plan.
