A new study led by researchers from the University of California, Irvine finds exercising in the morning, rather than at night, may yield better results.
Astronauts on long missions at the International Space Station can experience changes to their eyes and vision that can last for years. This study included 20 men who on three separate days at NASA's Johnson Space Center in Houston completed exercises while on their back and tilted back head-first (to simulate the effect of exercise in space); 10 of the participants wore swimming goggles.
Two papers appearing April 18, 2019 in the journal Cell Metabolism confirm that the circadian clock is an important factor in how the body responds to physical exertion. Based on this work alone, it's too early to say when the best time is for you to go for a jog. But at least in the lab, exercise in the evening seems to be more productive, although human lifestyles are much more complicated.
Like other biofluids, sweat contains a wealth of information about what's going on inside the body. However, collecting the fluid for analysis, usually by dripping or absorbing it from the skin's surface, can be time-consuming and messy. Now, researchers have developed a bandage-like biosensor that both collects and -- in conjunction with a smart phone -- analyzes sweat. The device, which could someday help diagnose diseases, is reported in ACS' journal Analytical Chemistry.
Does the potential to win or lose money influence the confidence one has in one's own decisions? Researchers (UNIGE) investigated confidence bias in a learning context through a system of monetary punishment and reward. They demonstrated that we become more confident in our choices when learning to seek rewards. However, this confidence evolves into over-confidence. Moreover, the monetary gains makes us less flexible, while the fear of losing money preserves our ability to adapt.
Chronic diseases are a key factor limiting the mobility of older people. Usually individuals are conscious of their condition in the case of an acute musculoskeletal disorder that causes pain or functional limitations. However, if the condition has progressed slowly, the gradual restriction of mobility often goes unnoticed.
On-road marked bicycle lanes are not the optimal solution to keeping cyclists safe, new research by Monash University has found.
People who engage in high-intensity interval training are at greater risk for injury, especially in the knees and shoulders, a Rutgers study found.
Overall physical activity starts to decline already around the age of school entry. While the proportion of physically inactive individuals rises with age there still are groups of people who manage to increase their physical activity level in adulthood and old age.
A new study found that offspring born to mice that exercised during pregnancy were less likely to gain weight after consuming a high-fat diet later in life. Although previous studies have shown that exercise by obese females benefits their offspring, this is the first research to demonstrate that the same is true when non-obese females exercise.
