Resumen
El objetivo de este estudio fue determinar el efecto de diferentes volúmenes de entrenamiento sobre la mejora del salto vertical. Método: se realizó una búsqueda de información en las bases de datos PubMed, MedLine y SportsDiscus donde se identificaron 59 artículos que cumplían los siguientes criterios: a) Estudios que incluyan programas de entrenamiento pliométrico de miembros inferiores, b) Que contengan programas experimentales y medidas válidas y seguras. Aquellos programas con un volumen de entrenamiento
de 8 a 12 semanas con una frecuencia de 2 a 3 sesiones semanales, en las cuales se realizan de 1 a 3 ejercicios con un total de 3 a 8 series por sesión y en las que se den una media de 70 a 100 saltos, parece ser la mejor combinación.

Abstract
Analysis of Plyometric Training Volume on Vertical Jump Height Performance. The aim of this study was to determine the effect of various plyometric training volumes on VJH performance. Method: we searched for information in the PubMed, MedLine and SportsDiscus databases where we identified 59 articles according to the inclusion criteria: a) Studies which included plyometric training programs for lower limbs, b) which contained experimental programs and valid and reliable measurements. The best combination seems to be training volumes between 8 and 12 weeks, with 2 or 3 training sessions per week, in which 1 to 3 exercises are performed with a total of 3 to 8 series per session and doing an average of 70 to 100 jumps.

Resumen: El objetivo de estudio es conocer los tipos de saques utilizados, dependiendo el momento del set en el que se producen. Este estudio ha sido desarrollado durante el torneo Nestea Spanish Master de Vóley Playa disputado en Valencia en el año 2006. La muestra de estudio la componen 10 jugadoras que conforman 5 equipos con un total de 4 encuentros analizados que suman 331 saques analizados. El análisis de las videograbaciones se llevó a cabo con el software SportCode Pro v.8.5.2. Los saques se clasificaron dependiendo del momento en el que se produjeron, siendo la franja 1 (del punto 1 al 7), franja 2 (del punto 8 al 14) y franja 3 (del punto 15 al 21). El análisis de datos se llevo a cabo con el software SPSS v.19. La prueba Chi-cuadrado, estableció diferencias significativas entre los diferentes tipos de saques para la franja 1 y 3 (p<.05), pero no se establecieron diferencias significativas en la franja 2 para los tres tipos de saque utilizado (p>.05). Se experimenta una disminución en el uso del saque en potencia (SP) de la franja 1 (84.1%) con respecto al de la franja 3 (4.8%), mientras que el saque flotante (SF) aumenta de la franja 1 (13.5%) a la franja 3 (81%). Finalmente el saque flotante (SF) en salto aumentan de la franja 1 (2.4%) a la franja 2 (28%) y decrece de esta última a la franja 3 (14.3%).

This study has been developed during the Master tournament Spanish Nestea Beach Volleyball Championship in Valencia in 2006. The study shows the 10 players that make up 5 teams with a total of 4 meetings totaling 331 serves analyzed. The analysis of the videotapes was conducted with SportCode Pro v.8.5.2 software. The serves were classified depending on the time in which they occurred, with the lane 1 (point 1 to 7), lane 2 (point 8 to 14) and lane 3 (point 15 to 21). Data analysis was conducted using SPSS v.19. The Chi-square test established significant differences between different types of serves for lane 1 and 3 (p<.05), but no significant differences were established in the range 2 for the three types of serve used (p > .05). You experience a decrease in the use of pull power (SP) band 1 (84.1%) compared to that of lane 3 (4.8%), while the floating kick (SF) increases the range 1 (13.5%) to lane 3 (81%). Finally floating kick (SF) jump increase of band 1 (2.4%) to band 2 (28%) and decrease of the latter to lane 3 (14.3%).

The working-experimentation, treats young basketball players aged 15-16 years (boys and girls), who in addition to attending classes, physical education and sport in schools they practice basketball in Pristina. The working-experiment contains a total of 7 morphological variables and four tests of basic motor skills and seven variables are situational motor abilities. In this research, it applied methods of t-test between morphological variables and basic motor skills and specific. Experimentation in question includes the number of 70 entities of both sexes; the group of 35 boys and the other group consist of 35 girls who have undergone the tests provided for this experiment.

The aim of this study is investigation of acute effect of circuit aerobic exercise and traditional aerobic exercise on hamstring muscle flexibility in sedentary women. Forty four sedentary women voluntarily participated in this study as subject. Subjects divided two groups as circuit aerobic training group (n=24), and traditional aerobic training group (n=20). For hamstring flexibility, modified sit and reach test was used. The test was applied three times as: before warm-up (T1), after immediately warm-up (T2), and after immediately exercise (T3). For warm-up intervention, 15 min mild running and static stretching were performed. Traditional aerobic exercise intervention consisted of 30 min moderate interval treadmill running. Circuit aerobic exercise intervention consisted of 30 min, 3x4 station (bench-step, jumping rope, cycling, treadmill running), and all station maintained to 3 min load with 2 min rest. Both training intervention performed at 65-75% HRmax that controlled with chest band. For statistical analysis, 2x3 mixed factor ANOVA and Bonferroni correction were used. Hamstring flexibility determined in the traditional aerobic exercise group as T1 by 13.90±4.22 cm, T2 by 19.90±4.55 cm, T3 by 29.45±6.54 cm; in the circuit aerobic exercise group as T1 by 21.20±6.89 cm, T2 by 24.08±6.67 cm, T3 by 25.62±6.67 cm. Differences between the three measurements of both groups were found statistically significant (p < 0.05). There were significant differences between T3 and T1-T2; and between T2 and T1 in both groups (p < 0.05). Differences in traditional aerobic exercise group were found more significant than circuit aerobic exercise group (p < 0.05). In summary, it could be said that hamstring flexibility increased after aerobic exercise, and at this point, traditional aerobic exercise has one step ahead of circuit aerobic exercise.

Post Activation Potentiation (PAP) is an acute enhancement of muscle function following a conditioning activity of high intensity. The majority of research regarding PAP has focused on the effects on maximal intensity movements, such as a vertical jump. There is limited information regarding the effects of PAP with the intent of improving submaximal muscular endurance performance. Purpose: The purpose of this study was to determine if a PAP warm-up (conditioning activity) would have a positive effect on the maximum number of repetitions one is able to successfully perform in the hex-bar deadlift (HDL) and barbell bench press (BP) at a submaximal intensity. It was hypothesized that the addition of a PAP conditioning activity to a dynamic warm up (DYN WU + PAP) would result in a greater number of repetitions performed compared to a DYN WU. Methods: Utilizing a repeated measures crossover design, eleven female NCAA track athletes participated in the six-session study. During the first ...
