Considering the high prevalence of dynamic valgus and its impact on sports performance among the female athletes, the present study aimed to examine the effect of a course of selective plyometric training on the lower extremity functional performance indexes of female athletes with dynamic knee valgus. Methods: This research was a quasi-experimental study with a pretest-post-test design. The study population comprised the athletic girls with dynamic valgus referring to Bu-Ali Sina gymnasium of the University of Hamadan in 2018. Of them, 26 eligible girls who met the inclusion criteria were selected purposefully and then randomly assigned into experimental (Mean±SD age=20.25±2.34 y, Mean±SD BMI=21.27±2.75 kg/m 2) and control (Mean±SD age=21.16±2.79 y, Mean±SD BMI=21.60±2.68 kg/m 2) groups. The experimental group performed specific plyometric training for 8 weeks, 3 times a week. Assessing the dependent variable was done using dynamic balance, Sargent and Illinois Agility tests in the pretest and post-test. The comparisons between experimental and control groups in the pretest and post-test were made by analysis of covariance and the dependent t-tests, respectively in SPSS V. 20. The significance level was set at 0.05 or lower. Results: Considering the pretest as the covariate parameter, a significant improvement was found for total dynamic balance (P=0.005), anterior leg (P=0.001), medial-posterior leg (P=0.001), lateral-posterior side of right leg (P=0.028), vertical jump (P=0.001) and Illinois jumping test score (P=0.001) in the experimental group. Conclusion: An improvement was seen in the dynamic balance and the movement performance of the participants with dynamic valgus after doing plyometric exercises that result in subsequent improvement in their exercise performance.

“…It seems that plyometric training programs by focusing on the knee alignment and improving the landing techniques during dynamic activities, reduce the angle of knee valgus and the ground reaction forces [10,11]. On the other hand, this training improves feedback and feedforward activities simultaneous with matching mus-…”

“…Notwithstanding these limitations, this study has important strengths. Despite the high injury rates in young artistic gymnastics [51] and the risk reducing benefits of strength and conditioning for young female athletes [33,52], there is a dearth of published literature examining individual training responsiveness of this population to neuromuscular training. This exploratory study offers a novel contribution to the literature by providing researchers and practitioners with insight into the differentiated responsiveness of young female gymnasts to a neuromuscular- and gymnastics-training stimulus.…”

This study examined individual responses in leg stiffness, reactive strength index (RSI), movement proficiency (deep overhead squat and in-line lunge), and trunk muscular endurance (flexor and extensor tests) in young female gymnasts following an 8-week neuromuscular training intervention. Thirty-four pre-peak height velocity (PHV) female gymnasts were divided into either an experimental group (EXP n = 17) or control group (CON n = 17). The EXP replaced their normal gymnastics physical preparation with a neuromuscular training program, while the CON continued with their habitual gymnastics program. Chi square analysis showed that the EXP resulted in significantly more positive responders compared to CON for measures of leg stiffness (41% versus 12% responded positively), extensor muscular endurance, (76% versus 29%), and competency in the deep overhead squat, (76% versus 29%) and in-line lunge (left lead leg) (65% versus 18%). Conversely, the number of positive responders for RSI (53% versus 61%), the flexor endurance test (88% versus 53%), and the right in-line lunge (47% versus 35%) were not significantly different between groups. These findings suggest that most young gymnasts responded positively to neuromuscular training from the perspective of improving movement proficiency and trunk endurance; however, changes in leg stiffness and RSI were more variable and may require higher intensities to realise further adaptations.

“…Further, three of the four artistic disciplines that female gymnasts compete in (vault, beam and floor exercise) are heavily reliant on explosive lower-limb rebounding and jumping activities, which all utilize various expressions of the stretch-shortening cycle (SSC) [36]. Consequently, rebounding and jumping performance of artistic gymnasts are commonly assessed to identify key determinants of the sport [8,29,31,50], determine physical profiles [46,53] and evaluate the efficacy of training interventions [7,11,28,37].…”

Purpose This cross-sectional study investigated dynamic force-time variables and vaulting performance in young female gymnasts of different maturity status. Methods 120 gymnasts aged 5-14 years were subdivided into maturity groupings using percent of predicted adult height (%PAH) attained. Participants performed three jumping protocols, the squat jump (SJ), countermovement jump (CMJ) and drop jump (DJ), before completing straight jump vaults that were recorded using two-dimensional video. Results Jumping performance improved with biological maturity evidenced by the most mature gymnasts' producing significantly more absolute force (P < 0.05; all d > 0.78), impulse (P < 0.05; all d > 0.75) and power (P < 0.05; all d > 0.91) than the least mature group, resulting in the greater jump heights (P < 0.05; all d > 0.70). While, no significant differences were observed in relative peak force across multiple tests, measures of relative peak power did significantly increase with maturity. Based upon regression analyses, maturation was found to influence vertical takeoff velocity during vaulting, explaining 41% of the variance in each jumping protocol. Across all tests, the DJ was found to have the highest predictive ability of vaulting vertical takeoff velocity, explaining 55% of the total variance. Conclusion Biological maturation impacts jump height and underpinning mechanical variables in young female gymnasts. Vaulting vertical takeoff velocity appears to be influenced by maturation and various dynamic force-time variables, particularly those during DJ, which had the highest explained total variance.

The effects of a four week jump-training program on frontal plane projection angle in female gymnasts

Abstract: The jump training program was successful in improving FPPA in female gymnasts and is advised to be implemented into the warm-ups and training programs of competitive female gymnasts to improve FPPA and therefore reduce the risk factors associated with knee injuries.
