Table 6.

Changes (%) in peak power and thigh-muscle quality, as affected by choline intake ¹.

	Low (n = 13)	Med–High (n = 24)	p-Values
Leg press peak power (%Δ in W)	19.0 ± 13.5	30.0 ± 22.4	0.072
Composite peak power (%Δ in W)	17.4 ± 12.5	25.5 ± 17.3	0.110
TMQ-S 2	12.3 ± 9.6	46.4 ± 7.0	0.010

¹ Data are presented as mean ± SD. Composite peak power = leg press peak power + chest press peak power. TMQ-S = leg press 1RM (kg)/total thigh lean mass for both legs (kg). All changes from baseline were statistically significant. ² ANCOVA analysis results presented as least-squares mean ± standard error (SE). Covariates appearing in the model: lean mass (kg), protein (g/kg lean/d), betaine (mg/kg lean/d), and vitamin B₁₂ (mcg/kg lean/d).
