Enhanced muscular strength and endurance can lead to improvements in the areas of:

  • Physical performance – mobility, flexibility, speed, cardiorespiratory fitness.
  • Injury prevention
  • Body composition
  • Muscle and Bone health (including bone density)
  • Metabolic health (blood pressure, triglycerides, HDL cholesterol levels, obesity levels)

Most importantly, greater muscular strength and endurance reduces the risk of premature death, regardless of age and family history.

Improved Physical Performance

Muscle quality and endurance ensure continued ability to perform everyday tasks with ease and enhance your performance at sports, to an advanced level. Resistance training improves your VO2 max (oxygen uptake), resulting in increased cardiorespiratory fitness.

Injury Prevention

Increased muscular strength and quality helps to ensure good spine alignment, prevent lower back pain, protects tendons, ligaments and cartilage and maintain good posture and proper body mechanics during walking, running and lifting. Progressive resistance training ensures the building of all major muscle groups.

Improved body composition

Strength training improves body composition by increasing muscle mass and increasing fat metabolism since the metabolic rate is related primarily to muscle mass. The greater the muscle mass the higher the metabolic rate. Resistance training can boost metabolism by up to 15% and fat metabolism continues after you train for up to 90 minutes.

Improved muscle and bone health

Resistance training prevents muscle and nerve degeneration that can compromise the quality of life. Muscle mass degeneration can be reversed through strength training, even in later life as can bone density loss be mitigated through regular training and a healthy diet.

Metabolic and heart health

Resistance training  can prevent and manage cardiovascular disease and diabetes through:

  • Improving glucose metabolism
  • Increasing VO2 max
  • Reducing blood pressure
  • Increasing HDL and reducing LDL
  • Improving blood vessel health

Stronger muscles reduce the demand on the heart. Eccentric training, in particular, has a lower demand on the heart and the uptake of oxygen.

Resistance training, insulin sensitivity and muscle function in the elderly

This review discusses the evidence supporting the fact that resistance training can not only improve strength in the elderly but also improve blood sugar control and dramatically decrease their risks of falls and fractures. (http://www.ncbi.nlm.nih.gov/pubmed/1714488)

Effects of Exercise Training in the Elderly: Impact of Progressive Resistance Training on Skeletal Muscle and Whole-Body Protein Metabolism

This review examines the evidence supporting the fact that the best possible exercise to slow the aging process is resistance exercise. Strength training rebuilds lost muscle, restores lost strength, and renews lost vitality. Even the elderly, unable to perform any “aerobic” training, were able to improve their insulin response, enhance their bone density, increase their cardiorespiratory capacity, and lower their levels of inflammation using only resistance exercise.

Strength Training Early After Myocardial Infarction

This study showed that resistance exercise, when compared with “aerobic” exercise, is completely safe even for middle-aged men who have just had heart attacks. In fact, 30 of the 42 men in the aerobic group suffered further heart problems during the study, while only one of the resistance training group experienced similar problems.

While minimizing cardiovascular energy cost, eccentric training can still maximize lean muscle gain. (http://www.ptjournal.org/cgi/pmidlook- up?view=long&pmid=1880185)
