 Cardiorespiratory Fitness (CRF) Lowers Cancer Risk

A well-established, graded, inverse association exists between cardiorespiratory fitness (CRF) and risk of cardiovascular disease (CVD) as well as all-cause mortality in numerous healthy and clinical adult populations.1- 3 Compared with those classified in the lowest CRF category (<7.9 metabolic equivalents [METs]), individuals in the highest CRF category (≥10.9 METs) have a 1.6- to 1.7-fold lower risk of CVD and all-cause mortality, respectively.4 Accordingly, measurement of CRF via for...

From Time Magazine article on the study:

Here’s the best part: it doesn’t take a lot of exercise to have a big health impact, Lakoski found. “Just a small improvement in fitness made a difference in survival of those that developed cancer,” she says. Compared to men who could run 12-minute miles on the treadmill at age 50, men who ran slightly faster 11.5-minute miles had an additional 10% decrease in cancer death and an extra 25% decrease in cardiovascular death among those who developed cancer in the study.

 Sitting Increases Chances of Cardiovascular Event

Methods: A population sample of 4,512 (1,945 men) Scottish Health Survey 2003 respondents (35 years) were followed up to 2007 for all-cause mortality and CVD events (fatal and nonfatal combined). Main exposures were interviewer-assessed screen time (<2 h/day; 2 to <4 h/day; and 4 h/day) and moderate to vigorous intensity physical activity. Results: Two hundred fifteen CVD events and 325 any-cause deaths occurred during 19,364 follow-up person-years. The covariable (age, sex, ethnicity,...

...the relative demand for skilled labor is closely correlated with advances in technology, particularly digital technologies. Hence, the moniker “skill-biased technical change,” or SBTC. There are two distinct components to recent SBTC. Technologies like robotics, numerically controlled machines, computerized inventory control, and automatic transcription have been substituting for routine tasks, displacing those workers. Meanwhile other technologies like data visualization, analytics, h...
