Activity profile of elite Gaelic football referees during competitive match play

Figures & data

Table 1. Relative distance in each movement category during the first and second half of match play.

	Match period
	First Half	Second Half	P value	ES (95% CI)
VLSM (m·min^−1)	1.9 ± 0.4	2.2 ± 0.5	<0.001	0.06 (−0.13 to 0.26)
Walking (m·min^−1)	25.7 ± 3.6	26.6 ± 3.5	<0.001	0.23 (0.03 to 0.42)
LSR (m·min^−1)	38.4 ± 5.4	35.2 ± 5.2	<0.001	−0.45 (−0.65 to −0.25)
MSR (m·min^−1)	47.1 ± 7.4	42.2 ± 7.0	<0.001	−0.50 (−0.70 to −0.30)
HSR (m·min^−1)	13.4 ± 5.3	12.3 ± 5.0	0.010	−0.14 (−0.34 to −0.05)
VHSR (m·min^−1)	0.3 ± 0.7	0.3 ± 0.5	0.137	0.08 (−0.12 to 0.28)

Data are presented as mean ± SD. VLSM, very low-speed movement; LSR, low-speed running; MSR, moderate-speed running; HSR, high-speed running; VHSR, very high-speed running.

Table 2. Relative distance in each movement category across the four quarters of match play.

	Match period
	First Quarter	Second Quarter	Third Quarter	Fourth Quarter
VLSM (m·min^−1)	1.9 ± 0.5	2.0 ± 0.6	2.1 ± 0.6^a, b	2.2 ± 0.7^a, b
Walking (m·min^−1)	24.2 ± 3.9	27.1 ± 4.1^a	25.5 ± 4.2^a, b	27.2 ± 4.2^a, c
LSR (m·min^−1)	40.2 ± 6.0	36.9 ± 6.4^a	36.1 ± 6.3^a	34.8 ± 6.4^a, b, d
MSR (m·min^−1)	51.0 ± 9.4	43.6 ± 8.7^a	43.6 ± 8.9^a	41.3 ± 9.0^a, d
HSR (m·min^−1)	15.2 ± 7.1	12.1 ± 5.7^a	12.5 ± 6.0^a	12.3 ± 6.7^a
VHSR (m·min^−1)	0.3 ± 0.9	0.3 ± 1.0	0.3 ± 0.7	0.4 ± 0.9

Data are presented as mean ± SD. ^a P <0.001 vs. First Quarter; ^b P <0.001 vs. Second Quarter, ^c P <0.001 vs. Third Quarter, ^d P <0.01 vs. Third Quarter. VLSM, very low-speed movement; LSR, low-speed running; MSR, moderate-speed running; HSR, high-speed running; VHSR, very high-speed running.

Figure 1. Relative distance (A) and the combined high and very high-speed running distance (B) across each quarter of match play. Data are presented as mean values with error bars representing SD and circles representing individual data points. HSR, high-speed running; VHSR, very high-speed running.

Figure 2. Effect size of the change in relative distance in each movement category from the (A) first to second, (B) first to third, (C) first to fourth, (D) second to third, (E) second to fourth and (F), third to fourth quarter of the AIC. Circles represent the ES, with the horizontal lines representing 95% confidence intervals. VLSM, very low-speed movement; LSR, low-speed running; MSR, moderate-speed running; HSR, high-speed running; VHSR, very high-speed running.
