Contact metrics

Contact intensity and frequency

The number of impacts greater than 7G and the number of tackles and rucks is reported for men’s club forwards and backs in Table 3 below.

Table 3. Contact intensity and frequency in men’s club forwards and backs (data from Suarez-Arrones et al 2014).

Data derived from GPS accelerometry (Table 3 above) indicate that both forwards and backs experienced a similar number of contacts/impacts (3.0 and 2.8 impacts per minute of play, respectively) during play. The number of impacts (per minute of play) reported for the sevens players are higher than those reported for the 15-a-side game where 1.8 and 2.1 impacts per minute of play have been reported for forwards and backs respectively (Cunniffe et al 2011).

Figure 5. A higher relative number of impacts occurs for the sevens player compared to the 15-a-side player.

During the game, players experienced an average of 26 impacts from 7 to 8G, 15 impacts from 8 to 10G and 3 impacts greater than 10G. The forwards in the sevens game engaged in a greater number of tackles compared to the backs throughout play. The total number of tackles performed for the sevens player (0.5 and 0.2 for forwards and backs, respectively) is greater than that reported for the 15-a-side player where 0.2 tackles per minute are reported for both forwards and backs (Coughlan et al 2011).
