More evidence on how exercise shapes our destiny

More evidence on how exercise shapes our destiny

Not CLL related, but more evidence that exercise shapes our bodies and our health. Analysis of baseline fitness data from a study of nearly 14,000 men compiled between 1971 and 2009, and lung, prostate, and colorectal cancer diagnoses and outcomes using Medicare data from 1999 to 2009, showed that improved mid-life fitness correlated with significant reductions in lung and colorectal cancer.

Better Fitness Leads to Lower Cancer Risk for Older Men

"Men with high cardiorespiratory fitness at midlife—between 46 and 51 years of age—have a 55% lower risk of lung cancer and a 44% lower risk of colorectal cancer compared with men with low cardiorespiratory fitness, according to a new study. High cardiorespiratory fitness was also associated with a lower risk of cancer-specific mortality at age 65 or older. However, this inverse association between fitness and cancer risk was not seen for prostate cancer."

Further, it looks like both genetics and exercise determine your body shape and brain, based on a study looking at 10 pairs of young adult identical twins in their early- to mid-20s, whose exercise habits had substantially diverged after they had left their childhood homes.

"Identical twins in Finland who shared the same sports and other physical activities as youngsters but different exercise habits as adults soon developed quite different bodies and brains, according to a fascinating new study that highlights the extent to which exercise shapes our health, even in people who have identical genes and nurturing."

" The sedentary twins had lower endurance capacities, higher body fat percentages, and signs of insulin resistance, signaling the onset of metabolic problems. (Interestingly, the twins tended to have very similar diets, whatever their workout routines, so food choices were unlikely to have contributed to health differences.)"

The twins’ brains also were unalike. The active twins had significantly more grey matter than the sedentary twins, especially in areas of the brain involved in motor control and coordination.


...the findings also point out that genetics and environment “do not have to be” destiny when it comes to exercise habits,


Even if the input from our DNA and upbringing urges us to skip the gym, we can “move more,” Dr. Kujala said, and, based on this study, rapidly and substantially improve the condition of our bodies and brains."

Thanks to Dick (Kwenda) for bringing the Finnish study to my attention.

  • I was discussing this with Bubnjay.

    My diet is still holding, and I've had another good week of exercise ... the Owws! have not stopped me so far ... so its good exercise in the mornings ( followed by heavy fatigue in the afternoon )

    How about we make a CLL fitness DVD ? ... it's an untapped market.

    Instead of resting between exercises ... we exercise between fatigues ! ... could someone get onto Andrew Schoor and see if we can borrow his camera !

    Then again ... it maybe as exciting as watching 'Big Brother TV ' ... you know, the bit at night when they are all asleep .....

    " And ACTION " .... zzzzzzzzzzzzzzz
