Introduction: Though TRX suspension training and CrossFit are similar methods of functional training, until now the differences in the effects on body composition and motor skills are not known.
Methods: A sample of CrossFitters and TRXers was enrolled and evaluated at the beginning of the study and after 6 months. body mass index (BMI), waist-to-height-ratio (WHtR), body fat percentage,
Sargent test and Balke test were used for the evaluation of the two groups.
Results: Fat percentage, WHtR showed a significant improvement over time, without statistical significant differences between the two groups. No statistical differences were found between groups for aerobic capacity, even if both present an improvement for all parameters during time (p<0.05).
The study revels also a greater increase for VO2max values in CrossFit group instead of TRX group, confirmed by the fact that changes in the values are related to the treatment group (p=0.01).
The average mean score for the Sargent test revealed how the modification of the values are explained for time (p=0.0002) and for groups (p=0.009).
Conclusion: Our study shows that both functional training methods lead to improvements both from an anthropometric point of view and from an aerobic resistance point of view. Additionally, CrossFit athletes method reveals a lower limb explosiveness and VO2max high values than the TRX group.
