- Widespread drastic reduction of brain myelin content upon prolonged endurance exercisewww.biorxiv.org Widespread drastic reduction of brain myelin content upon prolonged endurance exercise
Recent evidence suggests that myelin lipids may act as glial energy reserves when glucose is lacking, a hypothesis yet to be solidly proven. Hereby, we examined the effects of running a marathon on the myelin content by MRI. Our findings show that marathon runners undergo widespread robust myelin de...

- Cycling with Low Saddle Height is Related to Increased Knee Adduction Moments in Healthy Recreational Cyclists
Non-technical summary
This paper compares the biomechanics of the knee while cycling with the bike seat at different heights (low, medium, high, and preferred).
The paper shows that the movements of the knee that are most likely to contribute to overuse injuries are considerably more pronounced when the seat is placed low than when it is placed high.
>These results suggest the importance of adjusting saddle height for safe performance and injury prevention during cycling for recreational cyclists who rides daily for recreation, fitness, or transportation purposes, especially for people who ride from a bicycle-sharing system.
Highlights (taken from the paper)
-
The study aimed to compare different saddle heights on frontal plane knee biomechanics during cycling.
-
The knee may repeat thousands of abduction and adduction movements during cycling, and relatively low magnitudes of force and moment may cause injury if they last for a long time.
-
For this reason, it is not only the magnitudes of knee joint force and moment, but also their durations that are very important for understanding overuse injury.
-
Compared with Low saddle height, High saddle height reduced both knee moments and time duration, which suggest the importance of adjusting saddle height for safe performance and injury prevention during cycling for recreational cyclists.

In popular outdoor sports competitions, players, fans, and advertisers have to contend with an ambient environment of varying quality that is hard to predict weeks or even days in advance. The environment may deteriorate, for instance, because it is unseasonably hot, or due to the build-up of air po...

New research has shown one type of muscle contraction is most effective at increasing muscle strength and muscle size -- and rather than lifting weights, the emphasis should be on lowering them.
