Effects of Dietary ${\mathrm{N}\mathrm{O}}_{3^{-}}^{}$ on Peak Knee Extensor Torque and Power as a Function of Velocity in Healthy 65–79 Years Old Men and Women.

	Trial	Angular velocity (rad/s)
		0	1.57	3.14	4.71	6.28
Peak torque (Nm/kg)	Placebo	1.94 ± 0.36	1.42 ± 0.30	1.02 ± 0.26	0.75 ± 0.24	0.60 ± 0.21
	Nitrate	1.90 ± 0.40	1.38 ± 0.27	0.99 ± 0.23	0.75 ± 0.21	0.65 ± 0.20
Peak torque (% of isometric)	Placebo	100.0 ± 0.0	72.9 ± 5.0	52.3 ± 7.6	38.2 ± 8.0	30.7 ±7 .1
	Nitrate	100.0 ± 0.0	73.1 ± 7.3	53.2 ± 11.1	40.4 ± 11.7	34.5† ± 9.8
Peak power (W/kg)	Placebo	0.00 ± 0.00	2.04 ± 0.45	3.28 ± 0.79	3.77 ± 1.09	3.50 ± 1.43
	Nitrate	0.00 ± 0.00	1.96 ± 0.40	3.22 ± 0.70	3.84 ± 0.98	3.82‡ ± 1.29

Note. Values are mean ± SD for n = 12.

Nitrate trial significantly higher than placebo trial.: †p < .001; ‡p < .0001.
