Comparison of Training Changes in Upper-Body Strength in Men of Different Fat-Free Mass Indices

Fat-free mass index (FFMI) allows comparison of muscle mass equated for height and provides a more equitable mechanism for assessing the effect of resistance training (RT).  The purpose of this study was to compare the effect of RT on upper-body strength improvement in men of different FFMI.  Low, average, and high FFMI groups based on normalized scores performed similar linear periodization RT three days/week for 12 weeks.  Participants were measured for one-repetition maximum (1RM) bench press before and after training.  One-way ANOVA on absolute and relative strength gains indicated no significant different among the three groups after training.  Each group made similar absolute (~7.5 ± 6.1 kg) and relative (~9.1 ± 7.6%) increases in 1RM.  Beginning strength level was not significantly correlated with strength gain (r = -0.23, p = 0.71).  Men of equivalent FFMI will typically make similar gains in upper-body strength when training with a similar RT program.
