Pre-season rugby training develops the physical requisites for competition and consists of a high volume of resistance training and anaerobic and aerobic conditioning. However, the effects of a rugby union pre-season in professional athletes are currently unknown. Therefore, the purpose of this investigation was to determine the effects of a 4-week pre-season on 33 professional rugby union players. Bench press and box squat increased moderately (13.6kg, 90% confidence limits +/- 2.9kg and 17.6 +/- 8.0kg, respectively) over the training phase. Small decreases in bench throw (70.6 +/- 53.5W), jump squat (280.1 +/- 232.4W), and fat mass (1.4 +/- 0.4kg) were observed. In addition, small increases were seen in fat-free mass (2.0 +/- 0.6kg) and flexed upper-arm girth (0.6 +/- 0.2cm), while moderate increases were observed in mid-thigh girth (1.9 +/- 0.5cm) and perception of fatigue (0.6 +/- 0.4 units). Increases in strength and body composition were observed in elite rugby union players after 4 weeks of intensive pre-season training, but this may have been the result of a return to fitness levels prior to the off-season. Decreases in power may reflect high training volumes and increases in perceived of fatigue.
