Benchmarks of relative (in percent of body weight: %BW) conditioning maximum concentric (con) and eccentric (ecc) strength (Fmax) in order to maintain the elements swallow (S), support scale (SS), and inverted cross (IC) with one’s own body weight (100% BW) calculated with help of the linear regression equations.

Element	Fmax con S, SS (%BW)	Fmax ecc (%BW)	Equation con	Equation ecc
Swallow 100% BW	63.05% ± 3.80%	94.10% ± 5.63%	y = 0.45x + 18.43	y = 1.09x − 15.38
Support Scale 100% BW	60.37% ± 4.95%	86.79% ± 10.59%	y = 0.45x + 15.75	y = 0.89x − 2.53
Inverted cross 100% BW	56.66% ± 6.29%	70.86 ± 8.24%	y = 0.42x + 14.44	y = 0.32x + 38.72
