The reason I was in the lab was to try out a bright idea I've had with a colleague from Leeds Metropolitan for a study. One of the tasks I use to study perception and action is throwing over long distances to hit a target. I ask people to throw overarm to hit a 4ft x 4ft Perspex target from up to 15m away, and we record their throw with high speed cameras to measure the release angle and velocity of the ball. I'm also interested in the development of throwing; this is a very human skill, with all kinds of interesting psychological properties. It's considered a key motor skill for young children to acquire, so much so that it is one of the tasks measured in the Movement Assessment Battery for Children (Movement-ABC). This battery is commonly used to identify children with motor difficulties such as developmental coordination disorder, and throwing is one of the assessment tasks.

Children throwing bean bags at targets
Yesterday I spent a couple of hours in the Biomechanics lab here at the Centre for Sport & Exercise Sciences. The lab is fully instrumented, with 10 cameras mounted 360° around the room integrated with a force plate built into the floor. This arrangement allows us to place passive markers (small pieces of reflective plastic) on a person and track these within quite a large volume of space; if one camera loses sight of the marker, one of the others can typically see it. The data from the cameras and force platform come out with a common time stamp, so you can line the data up and see what was happening when.
