The Elite Sports Group (ESG) worked extensively with National Swimming coach Chris Nesbitt to improve the performance of his elite swimmers between 1999 and 2003. This involved providing personalised nutrition programs for Katy Sexton, and Simon Militus that were specially adapted to cope with the demands of sea level and altitude training. ESG sea level nutrition programs helped reduce illness and promoted faster recovery after training, with associated improvements in training quality. Our altitude nutrition programs reduced the detrimental effects of altitude and maximised training adaptations taking performance to a new level. These advanced nutrition programs coupled with cutting edge coaching from Chris Nesbitt made Portsmouth Northsea swimmers the most successful in the UK. Based on these successes ESG went on to provide nutritional advice to the Great Britain swimming team.
Simon Militus was British champion in the 200 m backstroke and 400 m individual medley (2001), and a bronze medalist at the 2002 Commonwealth Games in Manchester. In 2001 Militis was the first ever British swimmer to break the 4:20 barrier in the 400 m individual medley from the national trials, setting a new British record of 4.19.90. In the 200m backstroke at the 2002 Commonwealth Games he set a time of 2:01.04 in the final to win bronze.
