Resumen


The forces exerted on the suspension device have been examined in upper body exercises, like push-ups or inverted raw. For this reason, this aim of this study was to determine the effect of body position, contraction patterns and pace on force production by the lower limb during the execution of suspended lunge exercises. Ten physically active male university students (n = 10, age = 23.70±2.83 years old) performed sixteen suspended lunges in four different positions and three different paces (60, 70, and 80 beats per minute). A load cell was used to assess the forces exert on the suspension device. Force data were analyzed with the factorial repeated measurements (ANOVA). A significant main effect for position in concentric force (p= .000), average force (p= .002), and for frequency in peak force (p= .004) were found. Peak force was significantly higher for dynamic contraction type in all positions in comparison with isometric suspended lunge. In conclusion, a higher feet distance, frequencies around 70 beats per minute and the dynamic contraction type enhanced the forces exert on the suspension strap when performed the lunge exercise.
