2.4.1 Body Mass<br />

There has been a marked increase in the body mass <strong>of</strong> <strong>rugby</strong> <strong>players</strong> following the<br />

introduction <strong>of</strong> pr<strong>of</strong>essionalism due to selection pressure towards physiques that best match<br />

the requirements <strong>of</strong> the sport (Quarrie & Hopkins, 2007). The 1999 Rugby World Cup lends<br />

support to this conception as the most successful teams had greater mass in the forwards<br />

(Duthie at al., 2006). A greater body mass confers an advantage in the contact phases <strong>of</strong> the<br />

sport, because <strong>of</strong> the great momentum <strong>players</strong> are able to generate (Quarrie & Hopkins, 2007).<br />

An increased focus on weight training and usage <strong>of</strong> nutritional supplements may also have<br />

contributed to the increase changes in body mass (Duthie et al., 2003).<br />

Numerous studies have shown that there is a distinction between forwards and backs with<br />

respect to body mass <strong>of</strong> <strong>elite</strong> (Duthie et al., 2006; Meir & Halliday, 2005; Quarrie & Hopkins,<br />

2007), amateur (Maud, 1983; Quarrie et al., 1995), adolescent (Deutsch et al., 1998; Durandt<br />

et al., 2006) and female <strong>rugby</strong> <strong>players</strong> (Gabbett, 2007; Kirby & Reilly, 1993; Quarrie et al.,<br />

1995; Schick, Molloy, & Wiley, 2008). Amongst the 2006 Women’s Rugby Union <strong>players</strong>,<br />

the forwards (80.17 ± 10.10 kg) were significantly heavier that the backs (68.03 ± 10.10 kg)<br />

which is comparable to <strong>elite</strong> women’s <strong>rugby</strong> league forwards and backs (74.5 ± 12.5 kg vs.<br />

64.7 ± 7.6 kg) (Gabbett, 2007; Schick et al., 2008) (Table I). Differences in body mass have<br />

also been observed within the forwards and backs between U/16 and U/18 South African<br />

<strong>rugby</strong> <strong>union</strong> <strong>players</strong> (Durandt et al., 2006). Sixteen year old <strong>players</strong> weighing significantly<br />

less than the 18-year-old <strong>players</strong> (76.5 ± 8.2 vs. 84.9 ± 8.3 kg) with the props being the<br />

heaviest and scrumhalves the lightest in both age groups .<br />
