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.

This study examined the effect of 10-week complex strength training with elastic band program on fitness components in young female handball players. Thirty-eight handball players aged 15.8 ± 0.2 years were randomly assigned to an experimental group or control group. The experimental group performed complex strength training with elastic band twice a week over 10 weeks, which included 8 workshops of progressing set length (number of sets) and band resistance for each specific exercise. Sessions were lasted approximately 35 min. The control group maintained regular in-season training. Tests included handgrip; back extensor; medicine ball throw; 30 m sprint times; Modified Illinois change-of-direction (Illinois-MT); four jump tests (squat jump, countermovement jump, countermovement jump with arms and five jump test; static (stork test) and dynamic (Y balance test) balance; and repeated sprint T-test. The experimental group enhanced all strength performance (handgrip right ( p < 0.001), handgrip left ( p < 0.001), back extensor strength ( p < 0.001) and medicine ball throw ( p < 0.001) compared to the controls); sprint performance (5 m ( p<0.001), 10 m ( p < 0.001), 20 m ( p < 0.001), and 30 m ( p < 0.001)); the change of direction (Illinois-MT ( p < 0.001)); jump performance (squat jump ( p < 0.001), countermovement jump ( p < 0.001), countermovement jump with arms ( p < 0.001), and five jump test ( p < 0.01)); and the repeated sprint T-test scores ( p<0.001in all scores). In contrast, no significant difference in both static and dynamic balance performance between experimental group and control group. Ten weeks of complex strength training with elastic band improve fitness components measures in young female handball players then habitual training.

Background: Change-of-direction (CoD) is a necessary physical ability of a field sport and may vary in youth players according to their maturation status.Objectives: The aim of this study is: to compare the effectiveness of a 6-week CoD training intervention on dynamic balance (CS-YBT), horizontal jump (5JT), speed (10 and 30-m linear sprint times), CoD with (15 m-CoD + B) and without (15 m-CoD) the ball, in youth male soccer players at different levels of maturity [pre- and post-peak height velocity (PHV)].Materials and Methods: Thirty elite male youth soccer players aged 10–17 years from the Tunisian first division participated in this study. The players were divided into pre- (G1, n = 15) and post-PHV (G2, n = 15) groups. Both groups completed a similar 6-week training program with two sessions per week of four CoD exercises. All players completed the following tests before and after intervention: CS-YBT; 5 JT; 10, 30, and 15 m-CoD; and 15 m-CoD + B, and data were analyzed using ANCOVA.Results: All 30 players completed the study according to the study design and methodology. Adherence rate was 100% across all groups, and no training or test-related injuries were reported. Pre-PHV and post-PHV groups showed significant amelioration post-intervention for all dependent variables (after test &gt; before test; p &lt; 0.01, d = 0.09–1.51). ANOVA revealed a significant group × time interaction only for CS-YBT (F = 4.45; p &lt; 0.04; η2 = 0.14), 5JT (F = 6.39; p &lt; 0.02; η2 = 0.18), and 15 m-CoD (F = 7.88; p &lt; 0.01; η2 = 0.22). CS-YBT, 5JT, and 15 m-CoD improved significantly in the post-PHV group (+ 4.56%, effect size = 1.51; + 4.51%, effect size = 1.05; and -3.08%, effect size = 0.51, respectively), more than the pre-PHV group (+ 2.77%, effect size = 0.85; + 2.91%, effect size = 0.54; and -1.56%, effect size = 0.20, respectively).Conclusion: The CoD training program improved balance, horizontal jump, and CoD without the ball in male preadolescent and adolescent soccer players, and this improvement was greater in the post-PHV players. The maturity status of the athletes should be considered when programming CoD training for soccer players.

Maximal strength, power and his derivates (sprint, change of direction repeatedly and jump) are considered as major determinants of success in elite handball players. Contrast strength training with elastic band (CSTEB) program is form of resistance training, and may play an important method of training to improve this quality. This study examined the effects of 10-week contrast strength training with elastic band (CSTEB) program on physical performance in young female handball players. Thirty participants (age: 15.7  ±  0.3 years; body mass: 63.7  ±  3.7 kg; body height: 166.8  ±  3.8 cm; body fat: 26.9  ±  3.4; and Maturity-offset: 2.9  ±  0.3 years) were randomly assigned between experimental group (EG; n = 15) and control group (CG; n = 15). Two-way analyses of variance (group × time) were assessed for handgrip; back extensor; medicine ball throw; 30-m sprint times; Modified Illinois change-of-direction (Illinois-MT); four jump tests [(squat jump (SJ), countermovement jump (CMJ), countermovement jump with arms (CMJA) and five jump test (5JT)]; static (stork) and dynamic (Y balance) balance tests; and repeated sprint T-test (RSTT). The EG enhanced all strength performance [handgrip right, handgrip left, back extensor strength and medicine ball throw (p < 0.001)] compared to CG. The EG enhanced all sprint performance. The EG also improved performance in the Illinois-MT. All jump performance improved significantly [SJ (p = 0.007), CMJ (p = 0.001) and CMJA (p = 0.001)] except 5JT in the EG. Of the same, 3 of 4 repeated sprint T-test scores [RSTT-Best-Time, RSTT-Mean-Time and RSTT-Total-Time] increased significantly in the EG relative to the CG. Conversely, there were no significant changes in balance performance between groups. It is concluded that 10-weeks of CSTEB improved physical performance (strength, sprint, change of direction, jump, and repeated change of direction) measures in young female handball players.

Purpose: To analyze the effects of a 9-week plyometric training program on the sprint times (5, 10, 20, and 30 m), change-of-direction speed (modified T test and modified Illinois test), jumping (squat jump, countermovement jump, countermovement jump with arms, and horizontal 5-jump test), upper-body strength (right and left handgrip, back extensor strength, and medicine ball throw), and balance (Y and stork balance tests) of female handball players. Methods: Athletes were randomly divided into experimental (n = 21; age = 13.5 [0.3] y) and control (n = 20; age = 13.3 [0.3] y) groups. Training exercises and matches were performed together, but the experimental group replaced a part of their normal regimen by biweekly upper- and lower-limb plyometric training. Results: Both groups improved performance, but to a greater extent in the experimental group compared with controls for 20- and 30-m sprint times (Δ% = 9.6, P < .05, d = 0.557 and Δ% = 20.9, P < .001, d = 1.07, respectively), change of direction (T test: P < .01, Δ% = 14.5, d = 0.993 and Illinois test: P < .01, Δ% = 7.9, d = 0.769), vertical and horizontal jumping (P < .05), all measures of upper-limb strength (P < .001), and left-leg stork balance (P < .001, Δ% = 49.9, d = 1.07). Conclusions: A plyometric training program allows female junior handball players to improve important components of their physical performance.

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.

Plyometrics is a popular training modality for basketball players to improve power and change-of-direction speed. Most plyometric training has used sagittal-plane exercises, but improvements in change-of-direction speed have been greater in multidirection programs.Purpose:To determine the benefits of a 6-wk frontal-plane plyometric (FPP) training program compared with a 6-wk sagittal-plane plyometric (SPP) training program with regard to power and change-of-direction speed.Methods:Fourteen female varsity high school basketball players participated in the study. Multiple 2 × 2 repeated-measures ANOVAs were used to determine differences for the FPP and SPP groups from preintervention to postintervention on 4 tests of power and 2 tests of change-of-direction speed.Results:There was a group main effect for time in all 6 tests. There was a significant group × time interaction effect in 3 of the 6 tests. The SPP improved performance of the countermovement vertical jump more than the FPP, whereas the FPP improved performance of the lateral hop (left) and lateral-shuffle test (left) more than the SPP. The standing long jump, lateral hop (right), and lateral-shuffle test (right) did not show a significant interaction effect.Conclusions:These results suggest that basketball players should incorporate plyometric training in all planes to improve power and change-of-direction speed.

Introducción: A medida que se presenta el envejecimiento, los músculos disminuyen su tamaño y fuerza. La pérdida de masa muscular puede causar una disminución general de la función metabólica asociada a una baja producción hormonal anabólica y riesgo de lesión. La disminución de los niveles séricos de GH e IGF-1 debido al incremento de la edad pueden promover la fragilidad al contribuir a la pérdida de masa muscular y fuerza objetivo: Determinar efecto de un programa de entrenamiento de fuerza sobre IGF-1 en adultos mayores con obesidad e hipertensión controlada. Método: 8 adultos mayores con obesidad e hipertensión controlada, realizaron 6 semanas de entrenamiento de la fuerza con intensidades del 70% del 1RM, con una frecuencia de 4 veces por semana, previo al protocolo de entrenamiento se determinó triglicéridos, colesterol, glucosa e IGF-1 en sangre y medidas antropométricas (talla, peso, % grasa y masa muscular). Se aplicó un test de una repetición máxima (1RM) para evaluar la fuerza máxima en el tren superior e inferior antes y después del programa de entrenamiento. Resultados: Se observó un aumento significativo (p<0.05) en los niveles séricos de IGF-1, después de la realización del programa de entrenamiento. Conclusión: El entrenamiento de la fuerza con intensidades del 70% de la 1RM y frecuencia 4 realizado durante 6 semanas en adultos mayores con obesidad e hipertensión controlada, produjo incrementos en la concentración sérica de IGF-1 y un incremento de la fuerza muscular. Abstract. Introduction: As people age, muscles decrease in size and strength. Loss of muscle mass can cause a general decrease of metabolic function associated with low anabolic hormone production and risk of injury. The decrease in serum levels of GH and IGF-1 due to aging can provoke fragility by contributing to the loss of muscle mass and strength. Purpose: To determine the effect of a strength training program on IGF-1 in older adults with obesity and controlled hypertension. Method: a sample of 8 older adults with obesity and controlled hypertension performed 6 weeks of strength training with intensities of 70% 1RM and 10RM, with a frequency of 4 times per week. Prior to the protocol of Training, triglycerides, cholesterol, blood glucose IGF-1, and anthropometric measures (size, weight, % fat and muscle mass) were determined. The test of one maximum repetition (1rm) was performed to evaluate maximum force in upper and lower limbs before and after the training program. Results: A significant increase (p <0.05) was observed in serum IGF-1 levels after the completion of training program. Conclusion: Strength training with intensities of 70% of 1RM and frequency of 4 days/week, carried out for 6 weeks, produced increases in serum IGF-1 concentration and increased muscle strength in older adults with obesity and controlled hypertension.

Introduction: The aim of the study was to compare the impact of a 6-week program combined with football training and strength training on strength and power parameters in highly trained soccer players. It was hypothesized that 6 weeks would be enough for the experimental group to improve their jumping ability and pushing power. Material and methods: The study involved 34 female footballers playing in Ekstraliga (age: 22 ± 5 years; body height: 167 ± 5 cm; body weight: 60 ± 8 kg). The contestants were divided into an experimental group and a control group of 17 people in each group. The control group performed football trainings combined with 2 additional strength units (50% 1RM load) 3 times a week. The experimental group, apart from football trainings, additionally performed 2 strength trainings per week (50–85% 1RM load). Results: The results of the experiment show a significant improvement in the height of the vertical jump and bench press while sitting in the experimental group CMJ (p <0.05; p = 0.000029; ES: 1.00; 11%), CMJA (p <0.05; p = 0 00003; ES = 1.09; 13%), and LP (p <0.05; p = 0.027681; ES = 0.48; 6%), while in the control group the changes in the results after the training program were statistically insignificant CMJ (p> 0.05; p = 0.274000; ES: 0.07, 1%), CMJA (p> 0.05; p = 0.350958 ES = 0.27, 3%), and LP (p> 0.05; p = 0.130153; ES = 0.27; 4%). Conclusion: The presented research results suggest that a short, six-week training program including general football training and strength training performed twice a week with loads gradually increasing during the preparatory period may significantly improve the strength and jumping parameters of the lower limbs in soccer players. Such information can be valuable at the stage of training in the field of special skills training in football.
