In soccer, sprinting speed and vertical jump are critical skills to achieve high performance. Controversy exists about which type of training is most appropriate to improve these skills in youth players with no previous experience in programmed strength training. The aim of this study was to evaluate the efficacy and efficiency of a 16-week programme of resistance (weight) and plyometric training on sprinting and vertical and horizontal jumping in male youth soccer players. The study involved 18 soccer players, 14.1 ± 0.3 years old, with no previous experience in programmed strength training. They performed a combined cycle of resistance and plyometric training on different days, twice a week, respectively. Before and after the experimental intervention, the athletes were tested in countermovement vertical jump, bipodal horizontal jump, unipodal horizontal jump and 30 m linear sprint. After the intervention, significant improvements were observed in all the variables analyzed (p ≤ 0.05). Given that the relationship between the improvement in performance and the magnitude of the loads applied was shown to be superior to other similar interventions, it is possible to conclude that this type of training programme is both effective and efficient in the population studied.

Hammami, M, Negra, Y, Shephard, RJ, and Chelly, MS. The effect of standard strength vs. contrast strength training on the development of sprint, agility, repeated change of direction, and jump in junior male soccer players. J Strength Cond Res 31(4): 901-912, 2017-The aim was to compare the impact of 2 differing strength training (ST) programs on the athletic performance of junior male soccer players at a critical phase during their competitive season. Participants aged 16.0 6 0.5 years were randomly assigned between control (C, n = 12), standard ST (n = 16), and contrast strength training (CST, n = 16), each performed twice a week. Athletic performance was assessed before and after the intervention using 8 tests: 40-m sprint, 4 3 5-m sprint (S4 3 5), 9-3-6-3-9 m sprint with 1808 turns (S1808), 9-3-6-3-9 m sprint with backward and forward running (SBF), repeated shuttle sprint ability (RSSA), repeated change of direction (RCOD), squat jump (SJ), and countermovement jump (CMJ). The control group's (CG) performance tended to improve in some tests and decrease in others, but these changes were not statistically significant. Both training programs enhanced all sprint performances relative to controls (p # 0.05). The strength training group (SG) and the CST group (CSG) increased significantly in S1808, SBF, and S4 3 5 relative to CG, although the S4 3 5 also increased in CSG relative to SG (p # 0.05). No intergroup difference of RSSA performance was observed. The RCOD parameters increased significantly in CSG relative to both SG and CG (p # 0.05). The SJ and CMJ height increased significantly in both experimental groups (p , 0.000). We conclude that during the competitive season, some measures of athletic performance in male soccer players were increased more by 8 weeks of CST than by ST.
Effects of Training Exercises for the Development of Strength and Endurance in Soccer
Journal of Strength and Conditioning Research, 2008
A training program designed to increase strength and aerobic endurance in 1 season was tested on 16 professional soccer players from Spain with a mean age of 28 6 3.37 years. The schedule comprised 4 macrocycles of 12 weeks of aerobic endurance and strength training. As much for the strength training as for the aerobic endurance, the program used a sequence of general, special, and specific exercises. Assessments were made with routine tests (i.e., squat jumps [SJs], countermovement jumps [CMJs], and countermovement jumps with arm swing [CMJas]) at the end of each macrocycle, and the Probst test was used to assess aerobic endurance as a function of running speed and distance, at the start and end of the training schedule and at the start of the third macrocycle. Jumps were performed on an infrared platform fitted to the MuscleLab system. The Probst test showed differences between the first evaluation and the second and third evaluations: 3,550 6 411.59 m vs. 2,006 6 207.20 m (P , 0.01). For 2 of the 3 jumps analyzed, the results were better in the last 2 than in the first 2 evaluations (

Ferrete, C, Requena, B, Suarez-Arrones, L, and Sá ez de Villarreal, E. Effect of strength and high-intensity training on jumping, sprinting, and intermittent endurance performance in prepubertal soccer players. J Strength Cond Res 28(2): 413-422, 2014-The purpose of this study was to examine the effects of a 26-week on-field combined strength and high-intensity training on the physical performance capacity among prepubertal soccer players who were undertaking a competitive phase of training. Twenty-four prepubertal soccer players between the age of 8 and 9 years were randomly assigned to 2 groups: a control (C; n = 13) and an experimental group (S; n = 11). Both groups performed an identical soccer-training program, whereas the S group also performed combined strength and high-intensity training before the soccer-specific training. The 15-m sprint time (seconds), countermovement jump (CMJ) displacement, Yo-Yo intermittent endurance test (Yo-Yo IE), and Sit and Reach flexibility were each measured before (baseline) and after 9 (T2), 18 (T3), and 26 weeks (posttest) of training. There were no significant differences between the groups in any of the variables tested at baseline. After 26 weeks, significant improvements were found in the CMJ (6.72%; effect size [ES] = 0.37), Yo-Yo IE (49.57%, ES = 1.39), and Flexibility (7.26%; ES = 0.37) variables for the S group. Conversely, significant decreases were noted for the CMJ (210.82%; ES = 0.61) and flexibility (213.09%; ES = 0.94) variables in the C group. A significant negative correlation was found between 15-m sprint time and CMJ (r = 20.77) and Yo-Yo IE (r = 20.77) in the S group. Specific combined strength and high-intensity training in prepubertal soccer players for 26 weeks produced a positive effect on performance qualities highly specific to soccer. Therefore, we propose modifications to current training methodology for prepubertal soccer players to include strength and high-intensity training for athlete preparation in this sport.

Rodríguez-Rosell, D, Franco-Márquez, F, Mora-Custodio, R, and González-Badillo, JJ. Effect of high-speed strength training on physical performance in young soccer players of different ages. J Strength Cond Res 31(9): 2498–2508, 2017—The aim of the present study was to compare the effectiveness of low-load, low-volume weight training combined with plyometrics on strength, sprint, and jump performance in soccer players of different ages. Eighty-six soccer players from the same academy were categorized into 3 groups by age (under 13 years, U13, n = 30; under 15, U15, n = 28; and under 17, U17, n = 28) and then randomly assigned into 2 subgroups: a strength training group (STG) and a control group (CG). The strength training program was performed twice a week for 6 weeks and consisted of full squats (load: 45–60% 1 repetition maximum; volume: 3 set of 8–4 repetitions), jumps, and straight line sprint exercises. After training intervention, the STGs showed significant improvements in max...

Objectives. -To verify the influence of 10-week soccer training program on anthropometric, psychological, technical skills and specific performance parameters in youth players. Equipment and methods. -Thirteen young athletes were evaluated two times along the experiment (i.e. in T1, and T2). On the first day, anthropometric evaluation, sexual maturity status, flexibility and psychological parameters were assessed. On the second day, soccer technique tests were performed with 30 min of passive recovery in between. On the third day, the sprint tests (i.e. 10, 20 and 50 m) were measured. Finally, the lactate minimum test was performed on the fourth day.
Aim. -The purpose of this study was to evaluate the effects of a 16-week strength-training program applied to Chinese soccer players 15-19 years old. Methods. -Twenty-eight Chinese adolescent male soccer players (16.2 years ± 1.1) from Wsports Seven Team took part in this study. During 16 weeks after one-hour football training, the players took part in a supervised strength-training program. This strength-training protocol was administered three times a week, lasted 40 min approximately and in each session they split the muscles trained. On Tuesdays, they would train chest and biceps, legs and shoulder on Wednesday and back and triceps on Friday. In the beginning and after the 16-week intervention, we evaluated body composition, resting heart rate and blood pressure, maximal oxygen uptake, upper body resistance and one maximum repetition in the bench press and lat machine.

The aim of this study was to assess the effect of combining repeated-sprint training with two different methods of muscle strength training on physical performance variables in young players. Twenty-one (21) soccer players aged (±DS) 18.1 (±0.8) years; weight 69.9 (±6.5) kg and height 177.1 (±5.7) cm, competing in U-19 category, were randomly assigned to two experimental groups: Squat Group (SG: n=10) and -offs Group (TG: n=11). Intervention in both groups consisted of the combination of a weekly session of repeated-sprint training (the same for both groups), with two weekly sessions of strength training (different for each group), for 8 weeks in the final period of the season. The strength sessions for the SG consisted of conducting a series of Full Squats executed at maximum velocity in the concentric phase. Intervention in the TG was the performance of two specific strength exercises (take-offs and change of direction), with measurements taken before and after consideration of the following variables: repeated sprint ability (RSA); yo-yo intermittent recovery test (YYIRT1); counter-movement jump (CMJ) and average velocity in Full Squat progressive loads test (FS L ). The SG improved CMJ height in 5.28% (p≤0.05) and FS 37.5-47.5-67.5 (p≤0.05), while the TG improved FS 17.5-27.5-37.5-47.5-67.5 (p≤0.05). There were no significant changes in the values of RSA or YYIRT1 in either group. The results seem to show that the combination of a weekly session of repeated-sprint training with two weekly sessions of strength training could be an insufficient stimulus to improve RSA in the final period of the season.
Short-Term Compound Training on Physical Performance in Young Soccer Players
Sports
This study aimed to investigate the effects of a five-week compound training (with strength and plyometric exercises performed on separate days) on sprint, change of direction, and vertical jump in young soccer players. Eighteen novices in strength and plyometric training were assigned to either a compound training (CMPT) or a control condition (CNT). Both groups trained three times per week. One session was dedicated to soccer-specific drills. The other two weekly sessions were dedicated to circuit-based training routines employing on one-day strength exercises and on the other day plyometric exercises in the CMPT group. At the same time, the CNT group performed two weekly soccer-specific training sessions. All players were tested by 15-m sprint, change-of-direction and acceleration test (CODAT), squat jump, and countermovement jump with arms swing tests. CMPT group improved CODAT, squat jump and countermovement jump to a higher extent compared to CNT group (large vs small or trivi...
