Sixty-one time-motion analyses data-sets of twelve (12) senior male elite Zimbabwean rugby sevens players with a mean age of 27.8 years were gathered at two International Sevens rugby tournaments. Time-motion analysis data were captured at 10 Hz with a minimaxX GPS device. Results indicated that starter players covered a significantly greater distance (r = 0.26) than substitute players. However, substitute players covered a significantly greater relative distance (distance per minute) (r = 0.33) than the starter players. Hence, the substitute players had less rest during match play and therefore a higher work-to-rest ratio than the starter players. No large practically significant differen... |
