The relative effect of CXWORXTM versus TabataTM group exercise programs on body mass index, body composition, predicted VO2max and body image in adult exercisers

In this present work we took an initiation to compares the effects of two common approaches to group exercise: CXWORXTM and TabataTM , which employ differing exercise strategies, on common fitness measures and psychological perceptions.  The purpose of this study was to determine the effect of TabataTM versus CXWORXTM on body mass index (BMI), body composition, maximal oxygen uptake (VO2max) and Multidimensional Body-Self Relations Questionnaire (MBSRQ) measured self-perceptions in adult exercisers. The mixed gender sample consisted of a sub-set of 10 adult cross fit exercisers and 10 students from a regional comprehensive university class randomized to each exercise program. Analysis of Variance was used to examine program effects. While no significant main effect of the training period on body composition or BMI was found; mean VO2max was significantly increased as a large main effect across the study groups (F=1.054, P<0.05, η2 =0.533) without significant interaction. In addition, there was a significant large interactive effect of the training program and time to increase MBSRQ scores for appearance evaluation (F=1.648, P<0.05, η2 = 0.367), appearance orientation (F=1.447, P<0.05,  η2 = 0.377), fitness evaluation (F=1.637, P<0.05, η2 = 0.557), and body areas satisfaction (F=2.744, P<0.05, η2 = 0.533), in the CXWORXTM  group in comparison with the TabataTM group.  In conclusion, participants who completed a CXWORXTM exercise program increase VO2max similarly to participants who complete a TabataTM exercise program, while also reporting significant improvements in body image scores which the TabataTM participants did not. Neither program had a significant effect on body composition or BMI.
