Heavy Resistance Training and Supplementation With the Alleged Testosterone Booster Nmda has No Effect on Body Composition, Muscle Performance, and Serum Hormones Associated With the Hypothalamo-Pituitary-Gonadal Axis in Resistance-Trained Males

Table 3. Muscle strength variables for the PLAC and NMDA groups. Values are means (± SD).

Variable	Day	PLAC	NMDA	Test	Group x Test
BP Strength (kg·kg^-1)	0	1.18 (.39)	1.27 (.27)	p = 0.30	p = 0.91
	29	1.29 (.37)	1.38 (.29)	p = 0.30	p = 0.91
LP Strength (kg·kg^-1)	0	4.15 (1.55)	4.49 (1.75)	p = 0.04	p = 0.79
	29	4.98 (1.78)	5.25 (1.67)	p = 0.04	p = 0.79

Bench press (BP) and leg press (LP) strength for the PLAC (n = 10) and NMDA (n = 10) groups. * denotes a significant increase at Day 29. Resistance training increased leg press strength (p = 0.04) for both groups; however, there was no difference associated with NMDA supplementation (p > 0.05).
