Table 2. Test-retest ICC, CV% and SWC% for 1RM and 5RM kettlebell swing.

Intensity	ICC (±90% CL)	CV% (±90% CL)	SWC% (±90% CL)	ICC (±90% CL)	CV% (±90% CL)	SWC% (±90% CL)
	Trial 2–1			Trial 3–2
1RM	0.98 [0.96–0.99]	2.4 [1.9–3.3]	2.8 [1.9–3.5]	0.97 [0.94–0.99]	2.7 [2.2–3.7]	2.8 [1.9–3.5]
5RM	0.98 [0.95–0.99]	2.4 [1.9–3.3]	2.9 [1.9–3.6]	0.98 [0.96–0.99]	2.1 [1.7–2.9]	2.8 [1.9–3.5]

Note:

ICC, intraclass correlation coefficient; CV, coefficient of variation; SWC%, smallest worthwhile change, calculated as a 0.2 times the between-subject pure SD and represented as a percentage.
