Variety is the spice of life, and when it comes to what we eat, it may also extend our life.

Maybe you’re familiar with using bright-light exposure to shift your body clock so you can overcome jet lag more quickly. But what about exercising to achieve the same goal? Researchers at Arizona State University and the University of California, San Diego, found that exercising at 7 a.m. or between 1 p.m. and 4 p.m. was effective for advancing the body clock, whereas training between 7 p.m. and 10 p.m. worked to delay the clock. “Delays or advances would be desired . . .Read More
A recent study supports indoor cycling instructors who urge students not to pedal at a cadence above 90 revolutions per minute. Researchers found that at 90 rpm and beyond, pedal forces exerted by recreational cyclists decreased, heart rate increased by 15%, and exercise efficiency and skeletal muscle oxygenation declined.
The study appeared in the International Journal of Sports Medicine (2019; 40 , 305–11).Read More
