The aim of the present study was to compare the effects of 3 training protocols (plyometric [PLYO], agility [AG], or repeated shuttle sprints [RS]) on physical performance in the same population of young soccer players. Forty-two youth-level male players (13.6±0.3-years; 1.65±0.07 m; 54.1±6.5 kg; body fat: 12.8±2.6%) participated in a short-term (6-week) randomized parallel fully controlled training study (pre-to-post measurements): PLYO group, n=10; AG group, n=10; RS group, n=12; and control group [CON] n=10. PLYO training = 9 lower limb exercises (2-3 sets of 8-12 repetitions). The AG group performed planned AG drills and direction changes. RS training consisted of 2-4 sets of 5-6x 20 to 30 m shuttle sprints (20 seconds recovery in between). Progressive overload principles were incorporated into the programme by increasing the number of foot contacts and varying the complexity of the exercises. Pre/post-training tests were: bilateral standing horizontal jump, and unilateral horizontal jumps, sprint (30 m with 10 m lap time), agility (20 m zigzag), and repeated sprint ability (RSA) (i.e. 6x30 m shuttle sprints: 2x15 m with 180° turns). Significant main effects for time (i.e. training application) and group (training type) were detected. Improvements in horizontal jumping were higher (p<0.01: ES=large) in PLYO. The RS group improved significantly more (p<0.01; ES=large) than other groups: 30 m sprint, RSAbest and RSAmean performances. Significantly greater increases in 20 m zigzag performance were observed following AG and RS training (4.0 and 3.8%, respectively) compared with PLYO (2.0%) and CON training (0.8%). No significant differences were reported in the RSAdec between groups. Elite young male soccer players’ physical performances can be significantly and specifically improved either using PLYO or AG or RSA training over short-term in-season training.

“…Scientific literature reported that training programmes that use COD patterns assisted in the improvement of straight sprint performance, the COD ability and the muscular power and strength development [8]. However, many other studies have indicated that the COD training method did not improve these physical qualities [9, 10]. …”

“…Several CODs are executed during a team sports match, and players who can change direction fastest may have an advantage over their opponents during competition [3]. COD speed is dependent upon a number of factors, and previous studies suggest that straight sprinting speed and leg neuromuscular qualities could be important determinants in COD performance [1,5,6]. During a COD, it is necessary to execute force rapidly to accelerate, and to develop eccentric and concentric strength for decelerating and re-accelerating in the new direction.…”

“…Based on the relationships between linear sprint and strength, and also considering the forces generated during the contact phase in a COD, it was proposed that leg muscle qualities such as strength, power, and reactive strength could be important determinants of COD ability [1][2][3]. For this reason, the association between countermovement jump (CMJ) and drop jump (DJ) and COD was extensively studied without producing a clear consensus [6], while relationships with strength or power assessed through closed-kinetic chain exercises have been less examined [2]. While a group of studies show statistical relationships between COD and CMJ [4,6,10,14] and DJ performance [1,6,15], in contrast, others studies have shown lower relationships with no statistical associations with CMJ [8,13] and DJ [4,13,16].…”

The aim of the study was to investigate the relationships between countermovement jump (CMJ) height and inertial power in squat and sprint variables with change of direction (COD) performance. Fifty young healthy active males participated in the study. To determine these relationships, we carried out a 10-m linear sprint test (T 10 m), vertical jump tests (CMJ and CMJ Abalakov), an assessment of power relative to bodyweight in a flywheel squat (P bw ), and 10-m COD sprints with two different turn types (COD-90 • and COD-180 • ). T10 m showed statistically large and moderate correlations with T10 m COD-180 • (r = 0.55) and T10-m COD-90 • (r = 0.41), respectively. Moderate to large correlations between jumping height, linear sprinting, and sprints with COD were found (r = −0.43 to r = −0.59), and there were unclear correlations between jumping height and the loss of speed caused by executing COD (DEC-COD). P bw showed a large correlation with CMJ Abalakov and CMJ jump height (r = 0.65 and r = 0.57, respectively), and a moderate and large correlation with T 10 m, T 10 m COD-180 • , and T10 m COD-90 • (r = −0.33, r = −0.38, and r = −0.54, respectively). Despite the existence of substantial correlations between variables, straight linear sprinting, jumping performance, CODs and squat power were, for the most part, separate motor qualities (R 2 from 14% to 34%), suggesting that all of them should be specifically assessed and trained.

BackgroundSingle leg squat (SLS) is a widely used screening tool to assess lower limb dynamic control especially for knee valgus collapse. Dynamic function is determined from SLS through observation on knee alignment quality, and is proved related to lower limb, hip and core muscle strength,1–3 flexibilities and neuromuscular control patterns.4 On the other hand, the abovementioned items regarding muscle conditions are also well-known elements that contribute to physical fitness performance.5–9 Whereas there are limited studies on the relationship between SLS performance and lower limb fitness performance. Female youth soccer players were the selected population for this experiment, which was found to be most vulnerable to lower limb injuries due to gender anatomy and structure, for example ACL and ankle injuries.10–13 ObjectivesThe present study investigated the correlation between subjective assessment on SLS with performance of three fitness elements in youth female soccer players.Material and methodA total of 36 youth female soccer players (age = 13.6 ± 1.1; height = 156.1 & plusmn;7.7 cm; weight = 48.7 ± 10.2 kg) was recruited to perform the SLS and three soccer-specific fitness tests regarding explosiveness, speed, agility after anthropometric measurements and warm-up. The SLS task was recorded in video in frontal plane view then rated by exercise specialist as “good” or “poor” by considering movement quality (Table 1) and joint alignments (Figure 1).14–16 The fitness performance was compared between the SLS rating “good” and “poor” group using t-test. Spearman correlation coefficients were generated between the fitness performance and SLS ratings.Abstract P-101 Table 1Single-leg squat rating (in frontal view)2,14–16 Criteria Good Poor 1. Overall: Movement pattern unsmooth (Y/N) 2. Trunk: Moves out of neutral (Y/N) 3. Pelvis: Lateral tilt (Y/N) 4. Hip: Shift out of midline (Y/N) 5. Knee: Valgus motion/Oscillation (Y/N) (Medial/lateral side-to-side movement) 0-1 Yes 2-5 Yes ResultDemographics of participants between 2 SLS groups (good/bad) were no significant difference in age (13.9 ± 1.0/13.5 ± 1.0, P = 0.462), height (156.3 ± 7.0/155.5 ± 9.2, P = 0.785) and weight (48.1 ± 10.0/49.9 ± 10.9, P = 0.640). There was no significant difference between SLS group rated “good” and “bad” performed by dominant leg regarding fitness performance (Table 1). And no significant correlation between SLS performance and any of the three fitness elements.Abstract P-101 Table 2Between-group comparisons of fitness performance (Dominant leg) SLS-D Good (n = 11) SLS-D Poor (n = 21) t-test (p-value) Countermovement jump (cm) 35.0 ± 3.436.1 ± 3.1−.854 (.400) 20m sprint (s) 0-10m2.04 ± 0.122.00 ± 0.11.769 (.448)10-20m3.64 ± 0.163.58 ± 0.121.101 (.280) Arrowhead agility (s) Left9.53 ± 0.509.29 ± 0.361.564 (.128)Right9.43 ± 0.519.25 ± 0.341.172 (.251)Total18.96 ± 0.9918.54 ± 0.681.405 (.170)*SLS-D, single-leg squat performed by dominant leg.**The significance threshold was set at p < 0.05ConclusionSLS assessment by...
