Delving through some archived pages, I found this, and it is interesting how in the space of a couple of years, we finally seem to be drilling down on a couple of important issues.

Foam Rolling, Tennis balls and self massage: Witchcraft or Science?

Do you recommend foam rolling or using a tennis ball to "release" those trigger points? Is there any evidence to support this practice, and how useful is it really to "stretch" a structure that does not stretch, for example, the ITB?

Telomeres are the repetitive sections at the end of each chromosome that have been associated with longevity. Put simply, the longer the telomere, the longer the life. New research investigated the effect of physical activity on telomere length, and - perhaps unsurprisingly - found a positive association with physical activity.

Why athletic footwear MUST be rounded.

With the NBL finals coming up soon, much attention has been paid to what the stars will be wearing. And what they will be wearing is very different to past years, because the sole contour is rounded.

Heel counters and heel collars have NO effect on athletic performance!
