Effects of resistance training and
chromium picolinate on body composition and skeletal muscle
in older men. J. Appl. Physiol. 86(1): 29–39, 1999.—The
effects of chromium picolinate (CrPic) supplementation and
resistance training (RT) on skeletal muscle size, strength,
and power and whole body composition were examined in 18
men (age range 56–69 yr). The men were randomly assigned
(double-blind) to groups (n 5 9) that consumed either 17.8
μmol Cr/day (924 μg Cr/day) as CrPic or a low-Cr placebo for
12 wk while participating twice weekly in a high-intensity RT
program. CrPic increased urinary Cr excretion ,50-fold (P ,
0.001). RT-induced increases in muscle strength (P , 0.001)
were not enhanced by CrPic. Arm-pull muscle power increased
with RT at 20% (P 5 0.016) but not at 40, 60, or 80%
of the one repetition maximum, independent of CrPic. Kneeextension
muscle power increased with RT at 20, 40, and 60%
(P , 0.001) but not at 80% of one repetition maximum, and
the placebo group gained more muscle power than did the
CrPic group (RT by supplemental interaction, P , 0.05).
Fat-free mass (P , 0.001), whole body muscle mass (P ,
0.001), and vastus lateralis type II fiber area (P , 0.05)
increased with RT in these body-weight-stable men, independent
of CrPic. In conclusion, high-dose CrPic supplementation
did not enhance muscle size, strength, or power development
or lean body mass accretion in older men during a RT
program, which had significant, independent effects on these
measurements.
