įootball is the most popular sport among women however, little is known about the injury profile in this population. These differences may lead female players to be more prone to adopt altered lower extremity movements and motor control strategies during the execution of high intensity soccer-specific dynamic tasks (e.g.: cutting and landing) such as an excessive dynamic valgus motion at the knee and limited hip, knee and ankle flexion ranges of motion, which have been identified as dominant patterns for knee and ankle ligament injuries. Sex-related differences in body architecture and hormonal fluctuations as well as in biomechanics and neuromuscular control of the trunk, hip and knee may potentially explain why female athletes are more prone to sustain severe ligament injuries then males. In this sense, and for example, previous studies have documented that female athletes engaged in intermittent team sports (including football) have 2-6 and 2-5 more likelihood of suffering ACL tears and severe ankle sprains, respectively, than males. The most significant advances in the study were in the tests, in descending order of their weight: 60 s vertical jumps on both legs five back-and-forth jumps and five left/right side jumps, five vertical jumps on one leg standing, and BFS vertical jumps. The most relevant results obtained for the left leg regarding the improvement of the explosive force of the lower limbs materialized in the jump height parameter was in the test of five vertical jumps on one leg on the spot, and for the right leg in the tests of: five back and forth jumps and five left/right side jumps.

In all tests of the experiment monitored through Opto Jump, significant progress was made in the final test compared to the initial one, which demonstrates the efficiency of the physical training program implemented for the development of explosive force, with an impact on the sports performance of elite players. During the study, the tests were performed and processed on the Opto Jump device and software. In the study, the average value of the parameters specific to the jumps performed in each test was taken into account. For each test, the following parameters specific to the explosive force were statistically analyzed: contact time (s) flight time (s) jump height (cm), jump power (w/kg) RSI-Reactive Strength Index, defined as Height (m/s). Study tests: five vertical jumps on the spot, on the left/right leg five back and forth jumps on the left/right leg five left/right side jumps on the left/right leg vertical jumps on both legs 60 s BFS vertical jumps.

The research included 10 elite European and world-class players, on whom an experimental program was applied in order to improve the explosive force of the limbs in conditions of speed, endurance, and dynamic balance. The aim of the research was to implement an athletic program to improve the explosive force in order to optimize physical fitness at the level of elite football-tennis players and evaluate the progress made through specific tests using the Opto Jump. No significant differences were found over time in the VCG and in the NCG.Īn integrated postural exercise program might lead to a more balanced muscle efficiency inducing athletes to obtain a higher VJ performance. VJ performance was measured through the Sargent test before (T0), at 6 weeks (T1), and at 12 weeks (T2).Ī significant effect from T0 to T1 (p = 0.0017) and from T0 to T2 (p = 0.0001) was found in the VEG.

In addition, only the VEG underwent a 3-month postural exercise program of 30-45 min/session, twice/week. All three groups carried out the same volleyball training program. This pilot study included 19 young female volleyball players divided into the following groups: the Valgus Experimental Group (VEG) the Valgus Control Group (VCG) and the Neutral Control Group (NCG). Hence, the aim of this study was to investigate the effects of a postural exercise program on VJ height in young female volleyball players with knee valgus. Although a knee valgus position is related to the increase in injury risk in volleyball players, there is a lack of studies on the relationship between knee valgus and vertical jump (VJ) performance.
