Results: Within the young adult group, there were signiicant (p < .05) differences pre- to posttraining in
abdominal lexor, back extensor, SBL and SBR, balance, lexibility, and LB strength following training for
both the TRX and traditional groups. LB strength was improved more by RT (26.5% increase vs 13.1%
for TRX) and TRX showed greater relative improvements in both abdominal lexor (80.5% vs 52.9%) and
back extensor (31.1% vs 9.4%) endurance compared to RT. The other measures showed similar relative
improvements across time. The middle-aged adult group showed signiicant (p < .05) improvements
pre- to posttraining in back extensor, SBL and SBR, and LB strength following training for both the TRX
and RT groups. Conclusions: Overall, the indings indicate that TRX training improves muscular itness
variables in both younger and middle-aged adults that are generally associated with RT. This could prove
useful to individuals looking for more training options to gain both core endurance and muscular strength
simultaneously and enhancing the diversity of exercise choices.
