Relationships (Pearson’s correlation: r) between maximum strength test (Fmax) of the elements swallow, support scale, and inverted cross on rings and the conditioning maximum concentric (Fmax con) and eccentric strength tests (Fmax ecc) of the two different exercises on the computer-controlled device for swallow/support scale (S, SS) and inverted cross (IC) (**: p < 0.01; *: p < 0.05).

Element	Fmax con S, SS (kg)	Fmax ecc S, SS (kg)	Fmax con IC (kg)	Fmax ecc IC (kg)
Fmax Swallow (kg)	0.87 **	0.92 **	−0.05	0.64
Fmax Support scale (kg)	0.77 **	0.65 *	−0.69	0.39
Fmax Inverted cross (kg)	0.72	0.41	0.69	0.62
