Background Lumbopelvic control (LPC) has recently been associated with function, kinesiology, and load distribution on the limb. However, poor LPC has not been studied as a risk factor for lower limb injury in sports requiring frequent jump landings. The present study investigated the effects of LPC on landing mechanics and lower limb muscle activity in professional athletes engaged in sport requiring frequent landing. Methods This study was conducted on 34 professional female athletes aged 18.29 ± 3.29 years with the height and body mass of 173.5 ± 7.23 cm and 66.79 ± 13.37 kg, respectively. The landing error scoring system (LESS) and ImageJ software were used to assess landing mechanics. Wireless electromyography was also used to record the activity of the gluteus medius (GMed), rectus femoris, and semitendinosus. Lumbopelvic control was evaluated using the knee lift abdominal test, bent knee fall-out, active straight leg raising, and the PRONE test using a pressure biofeedback unit. Based on the LPC tests results, the participants were divided into two groups of proper LPC (n = 17) and poor LPC (n = 17). Results There were significant differences between the groups with proper and poor LPC in terms of the LESS test scores (P = 0.0001), lateral trunk flexion (P = 0.0001), knee abduction (P = 0.0001), knee flexion (P = 0.001), trunk flexion (P = 0.01), and GMed muscle activity (P = 0.03). There were no significant differences in the activity of the rectus femoris and semitendinosus muscles, and ankle dorsiflexion (P > 0.05). Conclusions Poor lumbopelvic control affects the kinematics and activity of the lower limb muscles, and may be a risk factor for lower limb injuries, especially of the knee.

“…The participants flexed both knees by 120° and were asked to slowly bend their hip to approximately 45° of abduction and external rotation while keeping their other limb in a neutral position and then return to the starting position, repeating the movement three times. Two joined PBUs were placed under the center of the back in L3 level and connected along the spine to avoid differences in the lumbar tactile cue, although only the data of the PBU from the moving limb were considered [ 39 ]. The positive or negative absolute mmHg deviation was registered for analysis.…”

It is suggested that core stability (CS) might improve rhythmic gymnasts’ performance. Nevertheless, the effect of core stability training (CST) in CS performance is not clear. Purpose: Evaluating the effect of an eight-week functional CST on young rhythmics gymnasts’ CS performance. Method: A sample of 45 young female rhythmic gymnasts from a competitive team (age = 10.5 ± 1.8 years, height = 144.1 ± 10.6 cm, weight 38.2 ± 8.9 kg, peak height velocity (PHV) = 12.2 ± 0.6 years) participated in the study. The participants were randomly allocated into the control group (CG) and experimental group (EG) and completed pre-tests and post-tests of specific CS tests using a pressure biofeedback unit (PBU). The CS was assessed by the bent knee fall out (BKFO), the active straight leg raise (ASLR) tests and the pelvic tilt test, all performed on the right and left sides. The EG (n = 23) performed an eight-week functional CST program based on rhythmic gymnastics (RG) technical requirements added to the traditional RG training sessions. Meanwhile, the CG (n = 22) received the traditional RG training sessions. Results: Mixed model analysis showed non-significant interaction effects; however, the ANOVA omnibus test showed a time effect (p < 0.05) in right BKFO (F1,42 = 4.60; p = 0.038) and both pelvic tilt tests (right F1,42 = 22.01, p < 0.001; left F1,42 = 19.13, p < 0.001). There were non-significant interaction effects. The fixed effects estimated parameters for right BKFO showed that both groups had less pressure variation after intervention compared with pre-intervention (β = −1.85 mmHg, 95%CI = [−3.54 to −0.16], t42 = −2.14, p = 0.038). Furthermore, the left pelvic tilt (β = 37.0 s, 95%CI = [20.4 to 53.6], t42 = 4.37, p < 0.001) improved 8.9 s more than the right pelvic tilt (β = 28.1 s, 95%CI = [16.3 to 39.8], t42 = 4.69, p < 0.001) considering both groups together. Conclusions: Adding a functional CST to regular training showed a trend in improving the performance of CS-related variables, which could help improve RG-specific performance. Coaches working with rhythmic gymnasts should consider adding a functional CST to regular training to improve CS performance leading to increased specific RG performance.

Background: Lumbopelvic control has recently been associated with function, kinesiology, and limb loading. However, poor lumbopelvic control has not been studied as a risk factor for lower limb injury in sports with frequent jump landings. The present study aimed to investigate the effects of lumbopelvic control on landing mechanics and lower limb muscle activity in professional athletes with frequent landing.Methods: This study was conducted on 34 professional female athletes aged 18.29±3.29 years with the mean height and weight of 173.5±7.23 centimeters and 66.79±13.37 kilograms, respectively. The lumbopelvic control of the subjects was evaluated using the knee lift abdominal test, bent knee fall-out, active straight leg raising, and PRONE test by the pressure biofeedback unit. Based on the test results, the participants were equally divided into two groups of with and without lumbopelvic control (n=17). Landing mechanics were evaluated by an expert blinded to the procedures using the landing error scoring system (LESS) and two-dimensional video analysis. In addition, electrical muscle activity in single-legged standing skills was assessed via surface electromyography.Results: The results of independent samples t-test indicated significant differences between the groups with and without lumbopelvic control in terms of the LESS test scores (P=0.0001), lateral trunk flexion (P=0.0001), knee valgus (P=0.0001), knee flexion (P=0.001), trunk flexion (P=0.01), and gluteus medius muscle activity (P=0.03). However, no significant differences were observed in the activity of the rectus femoris and semitendinosus muscles, and ankle dorsiflexion (P>0.05).Conclusions: Poor lumbopelvic control affects the kinematics and electrical activity of the lower limb muscles and may be a risk factor for lower limb injuries, especially knee injury.
