Antoine Albeau: muscle man

Following two consecutive days of fast and furious racing, the competitors were greeted on day 7 with glorious sunshine and flat calm waters off Jinha beach. All the signs were present for the thermal breeze to build, but by the cut off point of 14:00 the conditions remained the same.

This left the event leaders from day 6 basking in both the sun and their glory, having claimed victory at the first PWA slalom world tour event of 2010.

National Physical Laboratory (UK): Thickness of the wetsuit is more relevant than the surface finish

National Physical Laboratory has performed laboratory and field-based tests for UK wetsuit manufacturer, Spartan, to help further their knowledge of how wetsuits keep people warm.

NPL's specialised measurement equipment (including a guarded hot plate, wireless temperature sensors, and a thermal camera) was used to measure wetsuits' thermal performance. This provides valuable data on how much heat is lost through various parts of the wetsuit, and how quickly that heat is lost.

As anticipated, the lab results confirmed that the main factor in a wetsuit's ability to keep its user warm is the thickness of the material, as opposed to its surface finish.

The field tests (which took place on a breezy day in March 2010) on the other hand revealed what happens when wind chill effects become dominant – the surface finish of the wetsuit becomes all-important. The challenge for NPL is to further our understanding of wind chill, by directly measuring its effects.
