Clip description
Coached by Don Talbot, John Konrads’ technique is refined during training in the pool. Underwater tracking shots detail Konrads’ technique. Through training, Konrads builds stamina. This is scientifically measured back at the laboratory where lung capacity, heart rate and haemoglobin levels are all tested with machines. Medium-distance runner and Olympic gold medallist Herb Elliott is monitored on a treadmill.
