Although asymmetries in lower limbs have been linked with players’ performance in male soccer players, literature that has been published addressing female soccer is scarce. Thus, the aim of this study was twofold: (i) describe the asymmetries of women soccer players during jumping, change-of-direction and range-of-motion tests; and (ii) test possible relationships between asymmetries and injury risk in female soccer players. Sixteen female players (15.5 ± 1.5 years) performed a battery of fitness tests (i.e., jump ability, change-of-direction ability and passive range-of-motion) and muscle mass analysis via dual-energy X-ray absorptiometry, through which the specific asymmetry index and the related injury risk were calculated. Significant (p < 0.05) lower asymmetries in the change-of-direction test were observed in comparison to those observed in jumping and range-of-motion tests; significant (p < 0.05) lower asymmetries in muscle mass were also reported compared to those found in the change-of-direction and countermovement jump tests. Additionally, increased injury risk for countermovement jump and hip flexion with extended knee range-of-motion (relating to asymmetry values) and for ankle flexion with flexed knee range-of-motion in both legs (relating to reference range-of-motion values), as well as increased individual injury risk values, were observed across all tests. These findings suggest the necessity to implement individual approaches for asymmetry and injury risk analyses.

We describe a case of low back pain (LBP) secondary to a facet syndrome, with a magnetic resonance image of enlarged zygapophyseal inclusions, which both regressed with manipulative therapy. The role of the lumbar zygapophyseal inclusion in the pain syndrome remains uncertain, because there are no studies on these inclusions in the lumbar facet syndrome. The explanation of the role of manual therapy is also uncertain (adjusting joint subluxations, restoring bony alignment, reducing nuclear protrusion, reducing meniscoid entrapment or extrapment, decompressing facet joints, etc). The diagnosis of classical facet syndrome LBP was made by history-taking and physical examination. The diagnosis of intra-articular enlargements was made by magnetic resonance imaging. The manipulative therapy consisted of manipulations in rotation with the spine placed in kyphosis. Before every manipulation session, spontaneous pain, pain with pressure on the zygapophyseal joint and the range of thoracic and lumbar spine motions were evaluated. After the fourth manipulation session, the patient's pain was alleviated and the enlarged zygapophyseal inclusions were no longer visible. The clinical improvement continued at the controls one and two months after the end of the manipulative therapy. This is the first report of facet syndrome LBP with a magnetic resonance image of enlarged zygapophyseal inclusions which both regressed with manipulative therapy. It is interesting to speculate on the possible mechanisms to explain this outcome, but further studies are needed.

SummaryStudy aim: This study compared the effects of intermittent negative pressure therapy (INPT) vs. active recovery therapy (ART) on post-match physiological parameters such as serum CK level and skin temperature of the lower limbs in elite soccer players.Material and methods: Twenty healthy male professional soccer players from a Brazilian first division soccer club were enrolled in this randomized, parallel arm, open label, comparative study. After participating in 2 soccer matches, they were randomly assigned to two groups (n = 10) to receive a 30-min session of INPT (intermittent exchange of hypobaric pressure range 33 to 51 mmHg) or ART (self-myofascial release, mobility and stability exercises, and cycle ergometer exercise). The intervention was conducted after a match with assessments immediately before and after the intervention and again 24 h after the intervention.Results: A significant interaction effect (F2,36 = 4.503, p = 0.018, η2 = 0.130) was observed, indicating that the decrease of CK from pre-intervention to 24 h post-intervention was greater in the INPT than in the ART group. Lower limb skin temperature was significantly lower after INPT than after ART (p < 0.003).Conclusions: Serum CK level and skin temperature of lower limbs showed better recovery up to 24 h after the intervention with INPT in elite soccer players.

AbstractPurpose. The aim of the present study was assessment of laterality of the legs of young female soccer players and their non-training counterparts. Methods. The study sample comprised 9 female soccer players and 19 non-training girls. They underwent three measurement sessions, one every six months. The applied tests included kinesthetic differentiation, rate of local movements, static balance, single-leg hop, rate of global movements, strength and speed, and functional asymmetry of the legs tests. Results. The soccer players were better than the controls in their performance of the rate of local movements, rate of global movements, kinesthetic differentiation, single-leg 15m timed hop and static balance tests. Smaller differences between the results of the left and the right legs in soccer players, than in non-training girls, were noted in the rate of local movements, rate of global movements and kinesthetic differentiation tests. In the static balance test, the differences were greater in the group of soccer players. Conclusions. Lateralization of the lower limbs is a highly complex characteristic with a different variability in athletes than in nontraining individuals. The results of the present study also point to the specialization of soccer players’ left legs in body balance and single-leg hop tests.

The Stability

Stability plays a key role in the sport competition in football. Synchronized operation stabilization of the lower limb and trunk of the support with the dynamic movement of the contralateral limbs allow you to perform tasks specific to the discipline, eg. variety kicking of the ball. Purpose. The aim of the study was to evaluate differences in the capabilities to maintain postural stability in standing on one leg dominant and non-dominant leg with professional players including grouping variables: age, height, weight, volume of training aimed at improving the stability and general internship of football player career. Although commonly assumed that the non-dominant leg is predisposed to act more effective support for the body, the work to date have failed to identify indicated differentiation. It should be noted, however, that they were carried out on small trials in people less active, or among amateur athletes. Basic procedures. The study involved 31 professional soccer players from 1 to 5 level of division. In order to assess postural stability, each of the test performed three times a standard stability test consisting of three 20-second attempt to maintain balance on one leg becoming dominant and non-dominant leg on stabilometric platform BIODEX Balance System. For each of the lower limbs test was repeated three times. Assessment were average angular range deflections platform in the two reference planes, and the volatility of these deflections. These parameters were treated as a measure of postural stability of the respondents. Main findings. In the whole group of patients, no statistically significant differences in the possibilities to maintain postural stability in standing on one leg dominant and non-dominant leg. No significant differences were also detected when considering grouping variables. Conclusions. The results do not indicate a significant difference in the ability to maintain postural stability in standing on one leg dominant and non-dominant leg in professional soccer players.

Posterior branches of the lumbar spinal nerves are the anatomic substrate of pain in the lower back, sacrum and the gluteal area. Such pain may be associated with various pathologies which cause pain in the posterior branches of the lumbar spinal nerves due to entrapment, mechanical irritation or inflammatory reaction and/or degeneration. The posterior branches are of significant functional importance, which is related to the function of the structures they supply, including facet joints, which are the basic biomechanical units of the spine. Low back pain caused by facet joint pathology may be triggered e.g. by simple activities, such as body rotations, unnatural positions, lifting heavy weights or excessive bending as well as chronic overloading with spinal hyperextension. Pain usually presents at the level of the lumbosacral junction (L 5 -S 1 ) and in the lower lumbar spine (L 4-5 , L 3-4 ). In the absence of specific diagnostic criteria, it is only possible to conclude that patients display tenderness at the level of the affected facet joint and that the pain is triggered by extension. Differential diagnosis for low back pain is difficult, since the pain may originate from various structures. The most reliable method of identifying Lumbar Facet Syndrome has been found to be a positive response to an analgesic procedure in the form of a block of the medial branch or intraarticular injection. There appear to be good grounds for conducting further studies and developing unequivocal diagnostic tests.

The development of muscle power should be taken into account in soccer training. The aim of this study was to evaluate the influence of a 6-week of mixed power training on the level of the motor skills of the lower limbs of young soccer players. The training was conducted during the starting period. The study included twelve 16-18-year-old players who regularly participated in specific soccer trainings and played in regional competitions. Their basic anthropometric features were measured. The assessment of the power of the lower limbs was carried out using two jump tests: CMJ and SJ. The maximum anaerobic power was calculated and was expressed in relation to body weight and lean body mass. In addition, Drop Jump tests were performed from three different heights on the basis of which RSI reactive strength index were calculated. On completion of the training program an increase in the level of the results of all the tests was observed: SJ (cm) (cohen's d: 0.43), CMJ (cm) (cohen's d: 0.33), SJPmax (W/kg) (cohen's d: 0.43), CMJPmax (W/kg) (cohen's d: 0.30), SJPmax (W/LBMkg) (cohen's d): 0,57), CMJPmax (W/LBMkg) (cohen's d: 0,44), RSI 0,2 (cohen's d: 0,59), RSI 0,3 (cohen's d: 0,45), RSI 0,4 (cohen's d: 0,58). An additional six-week ballistic-plyometric training program, used as a supplement to the basic training plan during the start period, resulted in an increase in the motor skills of the lower limbs of young soccer players. The application of combined ballistic and plyometric training methods helps to improve the strength and speed potential of young soccer players.
