An increase in annual cardiorespiratory fitness by 3% or more is linked to a 35% lower risk of developing, although not dying from, prostate cancer, suggests research. They wanted to find out if improvements in cardiorespiratory fitness over time might influence these risks, drawing on a national occupational health profile assessment database. The database collected information on physical activity, lifestyle, perceived health, measurement of body mass and height, and the results of at least two cardiorespiratory fitness tests, measured by peddling on a stationary cycle, for 57,652 men out of a total of 181,673. Annual cardiorespiratory fitness measurements were expressed...

The shot encodes for relaxin, a hormone which is known to improve blood flow. Patients have received the injection in a phase one trial looking at dosage levels. Moderna CEO Stéphane Bancel told Sky News: 'It's like science fiction medicine.'

A high-dose vitamin K supplement reduced calcium precipitates associated with hardening of the arteries by 37 percent in rats, scientists from The Netherlands have reported. If the results can be reproduced in humans, high-dose vitamin K could have potential clinical implications for reducing arterial calcification, which is an important independent risk factor for the development of cardiovascular disease (CVD). “High vitamin K intake not only prevents calcification, but even regresses arterial calcifications,” lead researcher Leon Schurgers said. There are two main forms of vitamin K: phylloquinone, also known as phytonadione, (vitamin K1) which is found in green leafy vegetables such...

With their sleek aesthetics, club-inspired music, and cult-like followings, cycling studios have been on top of the trendy boutique fitness totem pole for the better part of the last decade, led by grapefruit-smelling, feel-good-mantra-spouting SoulCycle (which people seem to either love or hate). Competitors such as Flywheel and Peloton have tried to knock Soul off its throne, but there's a whole new game-changer beginning to take over the world of sweaty, sexy group workouts: indoor rowing. That's right, the machine that everyone ignores at the gym, the same old one collecting dust in your grandpa's basement, is poised to be...

Eat less saturated fat: that has been the take-home message from the U.S. government for the past 30 years. But while Americans have dutifully reduced the percentage of daily calories from saturated fat since 1970, the obesity rate during that time has more than doubled, diabetes has tripled, and heart disease is still the country’s biggest killer. Now a spate of new research, including a meta-analysis of nearly two dozen studies, suggests a reason why: investigators may have picked the wrong culprit. Processed carbohydrates, which many Americans eat today in place of fat, may increase the risk of obesity, diabetes...

 "Cardio kills," says Jim Karas in his new book, "The Cardio-Free Diet." "Cardiovascular exercise kills a weight-loss plan, your internal organs, your immune system, your time and your motivation. If your true goal is to lose weight, interval strength training is the only way to go," says Karas, an ABC News correspondent, celebrity trainer and fitness expert.    When he first tried to lose weight as a 21-year-old, Karas found that he would work up an enormous appetite after running several miles. So while his cardiovascular health improved he still wasn't losing weight. The Program He grew more interested in strength...
