Many people believe because they've reached a certain age physical training is no longer effective.

This is hogwash! A study showed that two groups (one of adults age 80+/- 4years) and one of (adults 40 +/- 4 years) saw the SAME increase in fitness after a 6 week training program.

Here's a link to the study.

Here's the abstract from the study:

Mitochondrial dysfunction is thought to be involved in age-related loss of muscle mass and function (sarcopenia). Since the degree of physical activity is vital for skeletal muscle mitochondrial function and content, the aim of this study was to investigate the effect of 6 weeks of aerobic exercise training and 8 weeks of deconditioning on functional parameters of aerobic capacity and markers of muscle mitochondrial function in elderly compared to young individuals. In 11 healthy, elderly (80 ± 4 years old) and 10 healthy, young (24 ± 3 years old) volunteers, aerobic training improved maximal oxygen consumption rate by 13%, maximal workload by 34%, endurance capacity by 2.4-fold and exercise economy by 12% in the elderly to the same extent as in young individuals. This evidence was accompanied by a similar training-induced increase in muscle citrate synthase (CS) (31%) and mitochondrial complex I-IV activities (51-163%) in elderly and young individuals. After 8 weeks of deconditioning, endurance capacity (-20%), and enzyme activity of CS (-18%) and complex I (-40%), III (-25%), and IV (-26%) decreased in the elderly to a larger extent than in young individuals. In conclusion, we found that elderly have a physiological normal ability to improve aerobic capacity and mitochondrial function with aerobic training compared to young individuals, but had a faster decline in endurance performance and muscle mitochondrial enzyme activity after deconditioning, suggesting an age-related issue in maintaining oxidative metabolism.
