Table 3. Results in division consistency (in %) of calculated muscle endurance ratios into “good” or “poor” ratio between trunk muscles in both groups of tests (n = 68).

Endurance ratio	A = B (%)	(A = poor) ∩ (B = good) (%)	(A = good) ∩ (B = poor) (%)	p
FL:EX	60.3	39.7	0	<0.001
R-LM:L-LM	70.6	17.6	11.8	0.503
L-LM:EX	83.8	10.3	5.9	0.549
R-LM:EX	82.3	11.8	5.9	0.338

Note:

A = B – share of unified division into “good” or “poor” ratio in both groups of tests, meaning: ((A = good) ∩ (B = good)) + ((A = poor) ∩ (B = poor)); (A = poor) ∩ (B = good) – share of reverse division in group A and B (resulted as “poor” ratio in tests A and as “good” ratio in tests B); (A = good) ∩ (B = poor) – share of reverse division in group A and B (resulted as “good” ratio in tests A and as “poor” ratio in tests B); p, Exact sig. (2-sided test) (McNemar test).
