The purpose of this study was to evaluate the effects of a complex training program, a combined practice of weight training and plyometrics, on explosive strength development of young basketball players. Twenty-five young male athletes, aged 14-15 years old, were assessed using squat jump (SJ), countermovement jump (CMJ), Abalakov test (ABA), depth jump (DJ), mechanical power (MP), and medicine ball throw (MBT), before and after a 10-week in-season training program. Both the control group (CG; n = 10) and the experimental group (EG; n = 15) kept up their regular sports practice; additionally, the EG performed 2 sessions per week of a complex training program. The EG significantly improved in the SJ, CMJ, ABA, and MBT values (p < 0.05). The CG significantly decreased the values (p < 0.05) of CMJ, ABA, and MP, while significantly increasing the MBT values (p < 0.05). Our results support the use of complex training to improve the upper and lower body explosivity levels in young basketball players. In conclusion, this study showed that more strength conditioning is needed during the sport practice season. Furthermore, we also conclude that complex training is a useful working tool for coaches, innovative in this strength-training domain, equally contributing to a better time-efficient training.

    • "Entre ellos, podemos destacar el entrenamiento con sobrecarga (Wilson, Newton, Murphy y Humphries, 1993), pliométrico (Markovic, 2007), electroestimulación (Paillard, Noe, Bernard, Dupui y Hazard, 2008) o entrenamiento vibratorio (Luo, McNamara y Moran, 2005) a pesar de no estar todavía demostrada su eficacia en el rendimiento. Generalmente, 2 métodos, el entrenamiento con resistencia o sobrecarga y el pliométrico, son referidos en la literatura específica como los más utilizados para la mejora de fuerza explosiva en jugadores de baloncesto (Santos y Janeira, 2008).

    • "Therefore, in the literature, other methods appear that usually differ in the type of exercise used (explosive, isometric or plyometric) and in the time between pairs of drills (without rest and with a rest interval between 3 and 18 minutes). Mostly, the rest periods between exercise pairs are important for the observation of post activation potential and these periods are separate and dependent on the level of strength and experience of the athlete (Young et al., 1988; Kotzamanidis et al., 2005; Tricoli et al., 2005; Kilduff et al., 2007; Santos et al., 2008). The need of prolonged rest periods between drill pairs affects negatively the dynamic of the training sessions. "

    ABSTRACT: Complex training (CXT) is the result of a combination of strength and plyometric exercises in the same session. This method has recently been used in the preparation of athletes of different sports. The aim of the present study was to observe the acute effects of a CXT program of 6 weeks: i) on agility with the ball, sprinting and the efficiency of crossing and shooting in youth soccer players; ii) and the influence of the number of CXT sessions per week (one vs. two). Sixteen youth male soccer players were randomly divided into three groups: a group that performed one weekly CXT session (GCT1, n = 5, age: 13.80 ± 0.45 years); or a group that performed two weekly CXT sessions (GCT2, n = 5, age: 14.20 ± 0.45 years); or a control group that did not perform the CTX (n = 6, age: 14.20 ± 0.84 years). All groups maintained their regular soccer training sessions. No significant interactions were found between GCT1 and GCT2 in all variables. Significant statistical differences were identified (F = 1139, p = 0.02, μp2 = 0531) in the pre-test versus post-test, for both experimental groups, in shot effectiveness. In conclusion, the CXT program proved to be an effective method in boosting abilities and motor skills associated with soccer among young athletes, particularly in increasing shot effectiveness.

    • "The information about the muscle activity during different figure skating jumps may be important for guiding the specific preparation of these athletes, with the appropriate selection of the exercises. Plyometric training is an example of specific preparation that can be used by skaters and stimulates the neuromuscular system, promoting improvement in jump performances (Ebben and Watts, 1998; Santos and Janeira, 2008; Lephart et al., 2005). Wu et al. (2010) analyzed the vertical jump (countermovement jump) height and the activity of the gastrocnemius lateralis and soleus muscles before and after eight weeks of plyometric training. "

    ABSTRACT: Authors submitted their contribution of the article to the editorial board. Accepted for printing This study aimed to describe the neuromuscular activity of elite athletes who performed various roller figure skating jumps, to determine whether the muscle activation is greater during jumps with more rotations and in which phase the muscles are more active. This study also aimed to analyze if there is any difference in the muscle activity pattern between female and male skaters. Four elite skaters were evaluated, and each participated in two experimental sessions. During the first session, anthropometric data were collected, and the consent forms were signed. For the second session, neuromuscular data were collected during jumps, which were performed with skates at a rink. The following four roller figure skating jumps were evaluated: single Axel, double Axel, double Mapes and triple Mapes. The neuromuscular activity of the following seven muscles was obtained with an electromyograph which was fixed to the waist of each skater with a strap: biceps femoris, lateral gastrocnemius, tibialis anterior, rectus femoris, vastus lateralis, vastus medialis and gluteus maximus. The signal was transmitted wirelessly to a laptop. During the roller figure skating jumps, the lateral gastrocnemius, rectus femoris, vastus lateralis, biceps femoris and gluteus maximus, showed more activation during the jumps with more rotations, and the activation mainly occurred during the propulsion and flight phases. Female skaters demonstrated higher muscle activities in tibialis anterior, vastus lateralis, vastus medialis and gluteus maximus during the landing phase of the triple Mapes, when compared to their male counterparts. The results obtained in this study should be considered when planning training programs with specific exercises that closely resemble the roller figure skating jumps. This may be important for the success of elite skaters in competitions.
