The Effect of Crossfit Training on the Central Hemodynamic Profile in Youth Wrestlers

Abstract

To determine the effectiveness of CrossFit training on the central hemodynamic profile in youth wrestlers, intervention study was attended by 48 wrestlers during the specialized foundational training stage. The average age of the studied wrestlers was 14.5 ± 0.3 years. The CrossFit group comprised 24 wrestlers participating in the CrossFit training aimed at enhancing functional state of the cardiovascular system. Meanwhile, the control group comprised 24 wrestlers following the standard program. Wrestlers engaged in CrossFit workouts three times a week for one hour over a six-month period as part of their physical conditioning. After CrossFit intervention the significant increase was observed in the CrossFit group by actual stroke volume by 12.98 ml/beat (р<0.001); cardiac output by 0.92 l/min; stroke index by 0.43 ml/beat/m² (р<0.001); left ventricular power by 1.05 W (р<0.01). Comparison of the post-training indicators of the rheography cardiovascular system showed the presence of probable differences between the studied groups (p<0.05-0.001). Advantages were observed in the wrestlers of the CrossFit group by all indicators compared to the wrestlers of the comparison group. The stroke volume value was higher in the wrestlers from the main group compared to the control group by 10.26 ml (p<0.01), while cardiac output was higher by 0.62 l/min (p<0.05). The results have indicated that the incorporation of high-intensity multifunctional CrossFit methods during the study resulted in positive dynamics in the preparedness level of wrestlers during the specialized foundational training stage.
