El fútbol es un deporte que, por la alta exigencia física que requiere, lleva asociado un elevado riesgo de lesión. Dada la magnitud del problema, los investigadores han optado por diseñar estrategias preventivas que ayuden a minimizar la incidencia de lesión en este deporte. Estas estrategias se han organizado como programas de calentamiento previo a la participación en el deporte. Sin embargo, la evidencia sobre el efecto agudo de estas intervenciones sobre parámetros del rendimiento físico es escasa. Por tanto, el objetivo del presente estudio fue analizar el efecto agudo del programa Knäkontroll (nivel B) sobre parámetros del rendimiento físico en jugadores de fútbol de categoría juvenil. Para ello, se utilizó un diseño cuasi-experimental pre-test y post-test, empleando la estabilidad dinámica de la extremidad inferior (Y-Balance Test), la cinemática de la caída en salto vertical (Tuck Jump Assessment [TJA]), el rango de movimiento articular de la dorsiflexión de tobillo (ROM-Sport), la distancia de salto horizontal unilateral (Single-Legged Hop Tests), y la altura de salto vertical unilateral (Single Leg Countermovement Jump [SLCMJ]) como principales medidas del rendimiento físico. Los resultados mostraron un incremento significativo del rendimiento para todas las variables tras la implementación del programa Knäkontroll, a excepción de la altura en el SLCMJ y la cinemática en el TJA. En conclusión, el programa Knäkontroll se presenta como una estrategia adecuada para su aplicación como calentamiento previo a la práctica del fútbol. No obstante, la inclusión de ejercicios (o variantes) adicionales que trabajen el componente pliométrico podría contribuir a la mejora del desempeño en el salto vertical.

Multidirectional running has been described as an important factor in team sports performance. The aim of the present study was to determine changes in T-test, 505 time, 10 m sprint, squat jump (SJ), countermovement jump (CMJ), countermovement jump right leg (CMJRL), and countermovement jump left leg (CMJLL) following exposure to 12 sessions over 4 weeks of a multidirectional running sprint training intervention in male and female handball players. A total of 31 handball players (15 male and 16 female) were recruited for this study and then randomly assigned to an experimental group (EG) or control group (CG). Male EG players showed improvements in 505 Preferred Side (PS) (p ≤ 0.05), 505 Non-Preferred Side (NPS) (p ≤ 0.05), and 10 m sprint (p ≤ 0.05), while female EG players presented statistically significant improvements between pre- and post-test for the T-test (p ≤ 0.05), 505 PS (p ≤ 0.05), 505 NPS (p ≤ 0.05), and 10 m sprint (p ≤ 0.05). No statistically significant pre- and post-test differences were observed in CG (all p ≥ 0.05) or between male and female players. We found an improvement in handball players’ agility and speed of movement following the intervention protocol, suggesting the need to introduce this program into our training sessions. It may also be necessary to select and develop more specific tests in order to evaluate multidirectional work in handball 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.

Zusammenfassung Hintergrund Ein Weg zur optimierten Verletzungsprophylaxe ist der Einsatz funktioneller Testbatterien im Sport. Auf Basis dieser Ergebnisse können korrigierende Übungen empfohlen werden, mit dem Ziel die Defizite zu beheben. Ziel dieser Untersuchung war es, Ergebnisse ausgewählter funktioneller Tests mit dem Auftreten von Verletzungen bei jugendlichen Handballspielern zu vergleichen. Material und Methoden An dieser Studie nahmen 31 Spieler aus den Nachwuchsmannschaften eines Handballbundesligisten teil. Vor Beginn der Rückrunde absolvierten alle Spieler den Functional-Movement-Screen, Y-Balance-Test, Front-Hop-Test, Side-Hop-Test und Square-Hop-Test. Alle Verletzungen, die nach der Testung aufgetreten sind, wurden bis zum Abschluss der Saison dokumentiert. Ergebnisse Innerhalb des Untersuchungszeitraums wurden 4 Nicht-Kontakt-Verletzungen und 4 Kontakt-Verletzungen registriert. Spieler, die eine Nicht-Kontakt-Verletzung erlitten haben, zeigten im Side-Hop-Test eine Seitensymmetrie von 78 % (Unverletzte und Kontakt-Verletzungen > 85 %) und im Y-Balance-Test einen Composite-Score von 87 % (Unverletzte und Kontakt-Verletzungen > 90 %). Für den Functional-Movement-Screen, die Front- und Square-Hop-Tests konnten keine deutlichen Unterschiede zwischen verletzten und unverletzten Spielern festgestellt werden. Schlussfolgerung Die Ergebnisse dieser Studie weisen darauf hin, dass innerhalb von Funktionsuntersuchungen im Handball neben Low-Threshold-Tests auch Testverfahren aus dem High-Threshold-Bereich angewendet werden sollten. Besonders geeignet für Handballsportler scheinen nach den Erfahrungen dieser Untersuchung der Y-Balance-Test und der Side-Hop-Test zu sein.

Purpose: To examine the effects of balance exercises conducted prior to complex training (bCT) versus complex training (CT) only on measures of physical fitness in young female elite handball players. Methods: Participants aged 17 years were randomly assigned to bCT (n = 11) or CT (n = 12). The 2 training interventions lasted 8 weeks with 2 sessions per week in replacement of some technical/tactical handball exercises and were matched for total training volume. Before and after training, tests were performed for the evaluation of proxies of muscle power (countermovement jump height, standing long-jump distance, and reactive strength index), muscle strength (back half-squat 1-repetition maximum), dynamic balance (Y-balance test), linear sprint speed (20-m sprint test), and change-of-direction speed (T test). Results: Two-factor repeated-measures analysis of variance revealed significant group × time interactions for the reactive strength index (d = 0.99, P = .03) and Y-balance test score (d = 1.32, P < .01). Post hoc analysis indicated significant pre–post reactive strength index improvements in CT (d = 0.69, P = .04) only. For the Y-balance test, significant pre–post increases were found in bCT (d = 0.71, P = .04) with no significant changes in CT (d = 0.61, P = .07). In addition, significant main effects of time were observed for half-squat 1-repetition maximum, countermovement jump, standing long jump, and T test performance (d = 1.50 to 3.10, P < .05). Conclusions: Both bCT and CT interventions were effective in improving specific measures of physical fitness in young elite female handball players. If the training goal is to improve balance in addition, balance exercises can be conducted within a CT training session and prior to CT exercises.

Trunk Stabilization

Background: Trunk stability is key in controlling body balance and movements. Trunk Stabilization Exercises (TSE) and Conventional Trunk Exercises (CTE) are performed to improve dynamic balance. The authors have previously reported that dynamic balance was improved by a 12-week and 6-week TSE program. However, there is a dearth of research on its immediate effect on dynamic balance in trained soccer players. Objective: To compare the immediate effeect of TSE with that of CTE on dynamic balance in trained soccer players. Methods: Forty-eight male soccer players (24.60 ffi 1.38 years) participated in this crossover study, wherein each participant took part in three exercise sessions: TSE, CTE, and No Exercise control (NE), each consisting of three steps: pre-test, intervention and post-test, with an interval of one week between each exercise condition. To assess dynamic balance, the Y Balance Test-Lower Quarter (YBT-LQ) score in the anterior, posteromedial, and posterolateral directions was measured before and 5 minutes after each intervention. Results: The YBT-LQ composite score was significantly improved after TSE (0.51) as compared to CTE (0.22) and NE (0.04) (p < 0.05). Furthermore, in TSE and CTE conditions, YBT-LQ scores of the posterolateral and posteromedial directions significantly improved at the post-test (p < 0.05). Conclusions: Both TSE and CTE are effective in immediately improving dynamic balance; however, TSE showed greater improvement as compared to the latter. Immediate improvements in the posteromedial and posterolateral directions of the YBT-LQ were demonstrated after performing the TSE and CTE.

The aim of this study was to evaluate the neuromuscular response to an agility and repeated sprint ability (RSA) test according to the level of competition in futsal players. A total of 33 players from two elite teams and one amateur team participated in the study. The participants completed an agility t-test, a 30 m-speed test, and a RSA test. A countermovement jump (CMJ) test and a tensiomyography test of the rectus femoris (RF) and biceps femoris (BF) of both legs were carried out before and after the tests. RSA test revealed better sprint times in elite players compared to amateurs in the seven bouts, as well as in the 30 m sprint and in the agility test (p &lt; 0.05). Before the tests, elite players showed higher sustain time (Ts) in RF (+31.03 ms; ES: 0.76) and BF (+28.73 ms; ES: 0.73), higher half-relaxation time (Tr) in BF (+20.79 ms; ES: 0.94), and lower delay time (Td) in BF (−2 ms; ES: 1.19) compared to amateur players. However, post-test values did not present any significant differences (p &gt; 0.05). In conclusion, elite players showed greater performance in the RSA test, in the 30 m tests and in the agility test compared to amateur players. The contractile properties were not a key factor in the RSA performance of the futsal players.

The aim of this study was to determine the effectiveness of an 8-form Tai Chi training exercise on balance performance, falling risk, and muscle strengths in elderly with limited strength. Twenty-six females between 70-85 years old with balance problem and moderate lower extremity muscular strengths (grade 2+ to 3+) without prior Tai Chi training volunteered for the study. The participants underwent the 8-form Tai Chi training exercise for 45 minutes/session, 3 sessions a week for 12 weeks. Balance performance (m-CTSIB, Postural Stability Balance Test, and 8-foot up-and-go Test), falling risk (Fall Risk Overall Stability Test and Fear of Falling Assessment), and muscle strengths (30-second Chair Stand Test and Pressure Biofeedback Unit Test) were assessed during pretest, mid-test, and post-test. One-way repeated measures ANOVA was conducted at the significant level of 0.05. The results after 6 weeks of training showed that balance and falling risk were improved where 8 foot up-and-go test and fear of falling assessment were significantly better than pre-experiment, while after 12 weeks, balance, falling risk, and lower extremity muscular strengths were significantly improved when compared to the pre-experiment. The 12-week 8-form Tai Chi training exercise was safe and effective in improving balance, falling risk, and lower extremity muscular strengths in ageing people with limited strengths.

The purpose of this study was to compare the effects of 4 weeks plyometric training on grass surface group and concrete surface on jumping performance among volleyball athletes. The vertical jump was evaluated in two types of jump; squat jump (SJ) and countermovement jump (CMJ). The result of this study indicates that the 4 weeks intervention showed a significant improvement in post test on SJ and CMJ (p < 0.05) for both grass surface and concrete surface. However, in comparing the grass surface and concrete surface, there was no significant difference (p > 0.05). These findings suggest that plyometric training on different surfaces may be associated with similar training-induced effects on the neuromuscular factors which are related to the efficiency of the stretch-shortening cycle.
