“…In addition, in the experimental group, the improvement of coordination abilities occurred in close connection with the improvement in the techniques implementation. The choice of these areas of sports training is consistent with the recommendations of other studies [36][37][38]. Modern researchers recommend using weights as a way of additional mobilization of analysers to improve special physical and technical readiness, increase coordination abilities.…”

Background and Study Aim. The work aim is to develop and experimentally test the combined impact method performance in the preparatory period of the annual macrocycle of 18–19 year old volleyball players (girls). Material and Methods. The study involved volleyball players (girls) aged 18–19 years old (n = 24, training experience – 9 years). Volleyball players (girls) were divided into control (n = 12) and experimental (n = 12) groups. Results. The method contributed to a higher rate of growth of most parameters of special readiness among volleyball players (girls) of the experimental group. A significant improvement in special readiness (p <0.05) was revealed for all parameters in both groups. In the experimental group, an improvement (p <0.001) was observed for 8 out of 11 parameters. In the control group, a significant improvement in the results (p <0.001) occurred in 3 cases out of 11. A significant improvement in speed and strength training parameters (p <0.001) was revealed: in 3 out of 4 cases (experimental group); in 1 out of 4 cases (control group). The quality of performance of the game basic techniques improved by: 4–22% (p <0.04–0.001 in experimental group) 4–11% (p <0.05–0.02 in control group). Conclusions. It is advisable to devote more time to the development of more significant motor abilities of volleyball players (girls) (speed, speed and strength, dexterity and coordination). It is advisable to improve endurance in combination with the development of other motor abilities and in the process of technical and tactical improvement. In the physical training of volleyball players (girls), it is advisable to use as many training means as possible, which are similar to the main game techniques according to spatio–temporal and dynamic characteristics. Movements with load contribute to the development of intermuscular coordination and allow to quickly form the correct idea of the trained motor action.

“…En el caso del voleibol, se han reportado efectos positivos por entrenamiento pliométrico en distintas semanas, tanto en la saltabilidad como en la fuerza explosiva (Berton, Lixandrão, Pinto e Silva, & Tricoli, 2018;Pereira et al, 2015;Sattler et al, 2018;Ziv & Lidor, 2010), en cuanto otro estudio realizo 6 semanas de entrenamiento pliométrico en agua en jugadores de voleibol femenino (15±1 años) reporto mejoras significativas en la saltabilidad (McKay et al, 2005), resaltando que el trabajo en el agua puede ayudar en la prevención de lesiones y adaptación de jóvenes jugadoras (McKay et al, 2005;Soylu, Altundað, Akarçeºme, & Yildirim, 2020).…”

El objetivo del estudio fue evaluar los efectos de un programa de entrenamiento pliométrico en la potencia muscular de niñas practicantes de voleibol (n=78; edad = 12,18±1,27 años). Las participantes fueron divididas subdividas de acuerdo con el grado de maduración en: grupo control (GC=48 con grado de maduración 2=11; 3=19; 4=19) y grupo de trabajo (GT=30 con grado de maduración 2=10; 3=10; 4=10). Ambos grupos realizaron 3 sesiones semanales de entrenamiento de voleibol, adicionando 3 sesiones de ejercicios pliométricos a GT que incluyeron salto en zigzag, lineales y profundidad. Para la evaluación pre y post entrenamiento se utilizó test Squat Jump, Saltos Movimiento, Drop Jump y Abalakov. La estadística prueba t student para significancia pre y post entrenamiento (p < 0,05) y también el análisis de la magnitud del efecto. Los resultados no reportaron diferencias significativas post entrenamiento a pesar de registrar pequeños y moderadas magnitudes de efecto. Se concluye que el entrenamiento polimétrico no genero efectos positivos en la saltabilidad de niñas púberes que practican voleibol. Abstract. The aim of this study was to evaluate the effects of plyometric training (PT) on muscle power (PR) of the lower limbs in girls volleyball players aged ( n=78; 12.18 ± 1.27years). Participants were divided according to the degree of maturation into control group (GC = 48 with maturity level 2 = 11; 3 = 19; 4 = 19) and working group (GT = 30 with maturity degree 2 = 10; 3 = 10; 4 = 10). held three sessions per week of volleyball and experimental group - EG n = 24, which held in addition of 3 weekly sessions of volleyball, more 3 weekly sessions of PT that comprised the multi jump, jump over hurdle and drop jumps. For pre- and post-training evaluation test was used Squat Jump, Counter Moviment Jump and Jump Drop Abalakov. The statistical student t test for significance Pre-post (p <0.05) and the analysis of the magnitude of the effect. The results reported no significant differences training post despite posting small to moderate effect sizes. It is concluded that the polymetric training did not generate positive effects on the saltability of pubertal girls who practice volleyball.

“…There is a substantial body of evidence that quadriceps muscle strength supports the knee joint during various balance tasks. A recent study by Soylu et al (2020) also demonstrated a negative significant correlation between the overall stability index ( i.e., Biodex Balance System) with knee extension, and flexion peak torque of the dominant and non-dominant limb of angular velocity at 60° s −1 and 180° s −1 in female volleyball players. Soylu et al.…”

“… Soylu et al. ’s ( 2020 ) results reveal that the dynamic balance performance of the athletes increased as knee extension and flexion muscle strength increased. A similar phenomenon was described by Williams et al (2016) , where stepwise backward-regression analysis included knee extension/flexion strength, among others, as a significant predictor of dynamic balance control ( i.e., single-leg jump landing) in a group of male soldiers.…”

Background Strength and balance are important factors for soccer players to be successful. This study’s aim was to determine the relationship between lower-limb muscle strength and balance control in elite male soccer players (n = 77). Methods Concentric isokinetic strength (peak torque of quadriceps (PT-Q) and hamstrings (PT-H), hamstrings/quadriceps (H/Q) ratio) was measured for the dominant and non-dominant leg at angular velocities of 60°s−1and 240°s−1, as well as the total work for extensors (TW-Q) and flexors (TW-H) for both legs (at an angular velocity of 240°s−1only). Balance score (BAL score) was used for unilateral assessment of balance control using a Delos Postural System Test measurement tool. Hierarchical multiple regression analyses were performed to predict balance control using isokinetic knee strength performance for dominant and non-dominant legs. Results Final modelling included peak torque of hamstrings at 240°s−1 and peak torque of the quadriceps at 240°s−1 for the non-dominant leg (R2 = 19.6%; p ≤ 0.001) and only peak hamstring torque at 240°s−1 for the dominant leg (R2 = 11.3%; p = 0.003) as significant predictors of balance score. Conclusion Findings indicate that balance control is widely influenced by peak hamstring torque and peak quadriceps torque at high angular velocity particularly in the non-dominant leg i.e., the supporting leg in soccer players.
