"hit the wall" during events like the marathon, and they have implications for the adaptations made in middle-aged adults who are using exercise to prevent or treat conditions like diabetes and obesity. If the mechanisms can be fully understood, it m...
Women up to age 30 at risk for bone loss, study finds

running on springy tracks; they use extended postures of knee and hip to give them straighter legs. Other recent work by the team shows that orang-utans use the natural springiness of branches to save energy in movement, especially when crossing from...
Study shows marine omega-3 fatty acids have positive effect on muscle mass

trying to increase their muscle mass. "However, it should not be seen as a miracle product," she points out. "For increased muscle protein metabolism to take place in people younger than 50, physical training is still required," she concludes....
Gene mutation linked to increased athletic performance in whippets

performance by disrupting MSTN either by natural or perhaps artificial means could change the face of competitive human and canine athletics." However, the authors stress that: "Extreme caution should be exercised when acting upon these results becau...
Research suggests a significant circadian rhythm in swim performance lasting 2-4 minutes

may be better able to shift their circadian systems so that the peaks of their performance rhythms coincide with the time of desired peak competition. In the highly competitive sports environment, where financial stakes are often high, team manage...
Training breathing muscles improves swimming muscles' performance
