Training Modalities

Purpose: To analyze and compare the effects of 4 different resisted sprint training (RST) modalities on youth soccer players’ performance after 8 weeks of training. Methods: Forty-eight youth soccer players were first randomly assigned to 4 groups and only then completed 8 weeks of RST: horizontal resisted sprint, vertical resisted sprint (VRS), combined resisted sprint, and unresisted sprint. Performance in horizontal and vertical jumps, sprint, and change of direction (COD) ability were assessed 1 week before and after the training intervention. Magnitude-based inference analysis was performed for calculating within-group pre–post differences. In addition, an analysis of covariance test was performed for between-group comparison, using the pretest values as covariates. After that, the analysis of covariance P values and the effect statistic were transformed to magnitude-based inference. Results: Within-group outcomes showed that all resisted training modalities experienced improvements in sprint (small to moderate) and COD (small to large) performance. Moreover, all groups, except unresisted sprint, enhanced the horizontal jump performance. However, only VRS improved on vertical jump. Between-group comparison outcomes revealed that only VRS improved the sprint time compared with horizontal resisted sprint (moderate) and COD performance compared with all groups (moderate to large). In addition, VRS enhanced the countermovement jump performance (small to large) compared with the other groups. Conclusions: Independent of the orientation of the resistance applied, RST is an effective training method for improving sprinting and COD performance. Nevertheless, VRS may promote greater improvements on sprint and COD ability and have a positive additional effect on countermovement jump performance and the reduction of COD deficit.

The aim of the study was to determine the effects of short-term (4 weeks, twice a week: 8 sessions) plyometric training on agility, jump, and repeated sprint performance in female soccer players. The study comprised 17 females performing this sports discipline. The players were randomly divided into two groups: with plyometric training (PLY) and the control (CON). All players followed the same training program, but the PLY group also performed plyometric exercises. Tests used to evaluate physical performance were carried out immediately before and after PLY. After implementing the short PLY training, significant improvement in jump performance (squat jump: p = 0.04, ES = 0.48, countermovement jump: p = 0.009, ES = 0.42) and agility (p = 0.003, ES = 0.7) was noted in the PLY group. In the CON group, no significant (p > 0.05) changes in physical performance were observed. In contrast, PLY did not improve repeated sprint performance (p > 0.05) among female soccer players. In our research, it was shown that PLY can also be effective when performed for only 4 weeks instead of the 6–12 weeks typically applied.

Objective: The aim of this study is to find out the relationships among body composition, Yo-Yo intermittent recovery (IR) test and vertical jump test in elite young soccer players. Material and Methods: Eighteen healthy young male soccer players (Age: 16.5±0.3 years, height: 178.0±5.9 cm, body weight: 65.9±7.9kg,) voluntarily participated in the study. Total and regional body composition parameters of the soccer players were examined through a dual-energy x-ray absorptiometry (DEXA) method. Vertical jump performance tests were squat jump (SJ) and active jump (AJ), and endurance performances were determined by the Yo-Yo intermittent recovery level 1 test (Yo-Yo IR1). Relationships among body composition, Yo-Yo intermittent recovery test and vertical jump test were analyzed with Pearson Correlation coefficient. Significance level was taken as ≤0.05. Results: A statistically significant negative correlation was found between squat jump and countermovement jump (r=-0.588, r=-0.573, p<0.05), and the leg fat rate. However, there were no statistically significant relationship among squat jump, Yo-Yo IR1 and countermovement jump and other whole/regional body composition (p>0.05). Conclusion: Changes in body composition are important issues for the physical performance level of young soccer players, as local excess body fat may cause deterioration, especially in jumping performance.

It has previously been shown that a loaded warm-up may improve power performances. We examined the acute effects of loaded dynamic warm-up on change of direction speed (CODS), which had not been previously investigated. Eight elite badminton players participated in three sessions during which they performed vertical countermovement jump and CODS tests before and after undertaking the dynamic warm-up. The three warm-up conditions involved wearing a weighted vest (a) equivalent to 5% body mass, (b) equivalent to 10% body mass, and (c) a control where a weighted vest was not worn. Vertical jump and CODS performances were then tested at 15 seconds and 2, 4, and 6 minutes post warm-up. Vertical jump and CODS significantly improved following all warm-up conditions (P< .05). Post warm-up vertical jump performance was not different between conditions (P= .430). Post warm-up CODS was significantly faster following the 5% (P= .02) and 10% (P< .001) loaded conditions compared with the control condition. In addition, peak CODS test performances, independent of recovery time, were faster than the control condition following the 10% loaded condition (P= .012). In conclusion, the current study demonstrates that a loaded warm-up augmented CODS, but not vertical jump performance, in elite badminton players.

El objetivo del presente estudio fue analizar la influencia del puesto específico desarrollado en el terreno de juego por jóvenes futbolistas en la capacidad de salto, sprint, agilidad y velocidad de golpeo. Participaron 36 jugadores de nivel sub-élite provenientes de las categorías inferiores (cadete y juvenil) de equipos de fútbol andaluces (edad: 15.87 ± 1,43 años; masa corporal: 65.38 ± 10,84 kg; altura: 1.71 ± .06 m). Se evaluó la composición corporal, el rendimiento en salto vertical (CMJ), la agilidad mediante el test de Balsom, velocidad de sprint en 5, 10, 20 y 30 metros, y la velocidad de golpeo con ambas piernas. Los análisis mostraron que existen diferencias entre delanteros y defensas en la velocidad en 20m (p = .012) y entre delanteros y mediocampistas en la velocidad en 30m (p = .008). En las demás variables no existen diferencias entre las distintas posiciones de juego. Se concluye que durante la etapa de formación del futbolista, en este caso adolescencia, el nivel de especialización de los mismos no es alto y, en consecuencia, su condición física no presenta unos rasgos marcados, específicos de una determinada posición en el campo, probablemente debido a que en estas edades y niveles, se persigue una formación integral del deportista y un desarrollo lo más amplio posible, tanto a nivel físico como técnico-táctico.Palabras clave.

The main objective of this paper was to analyze the influence of specific position in vertical jump ability, sprint, agility and kicking speed in young soccer players. 36 soccer players of sub-elite level from Andalusian youth soccer academies participated voluntarily in this study (age: 15.87 ± 1.43 years; body mass: 65.38 ± 10.84 kg; height: 1.71 ± .06 m). Body composition, vertical jump performance (CMJ), agility through Agility Balsom Test, sprint in 5, 10, 20 and 30 meters, and kicking speed with both legs, were performed. Analysis showed differences between forwards and defenders with respect to 20m speed test (p = .012), and between forwards and midfielders with respect to 30m speed test (p = .008). In other variables there were not significant differences according to the specific position. It is concluded that during the formation stage of a soccer placer, in this case, for adolescence, specialization level is not high, therefore differences were not found by specific position probably because in these ages and levels, the aims are a comprehensive training and physical and technical-tactical soccer player development.KeyWords.

Abstract The aim of this study was to compare the acute effects of performing half squats (HSs) with different loading intensities (1, 3, and 5 repetitions maximum [RM], and 60% 1RM) and a different number of sets (1, 2, and 3) on the countermovement jump (CMJ) performance of 18 highly‐trained male subjects. Participants were submitted to four experimental conditions (1RM, 3RM, 5RM, and 60% 1RM) in randomized order. The CMJ was assessed before and after each set. Differences in CMJ performance between the distinct experimental conditions and individual responses in CMJ performance induced by the different protocols were analyzed via the magnitude‐based inference method. Overall, significant improvements were detected in individual CMJ heights after each activation protocol. It can be concluded that the use of 1 to 3 sets of HSs performed at moderate‐to‐high loads may be an effective strategy to improve jump performance in highly‐trained subjects. Nonetheless, despite the high efficiency of the protocols tested here, coaches and researchers are strongly encouraged to perform individualized assessments within the proposed range of loads and sets, to find optimal and tailored post‐activation potentiation protocols.
