“…The analysis of relationships between straight and change-of-direction sprint tests added new evidence to the understanding of speed and agility performance. As already demonstrated in adult and young rugby players 3,4 and young basketball players, 5 college football athletes showed a significant relationship (r = .86, P < .0001) between straight sprint and sprint with changes of direction, sharing 74% of common variance. Furthermore, this relationship is supported by the idea of Young et al, 6 who argued that the greater the change-of-direction angle the less the skills have in common.…”

The aim of the current study was to investigate the relationship between straight-sprint and change-of-direction performance. Total sprinting time and split time at 5 m were collected from 44 college football players during a 15-m straight sprint (SS15m) and a 15-m zigzag sprint with two 60° changes of direction (COD15m). Differences in sprinting time between COD15m and SS15m and between COD5m and SS5m were expressed as percentage of decrement at 5 m and 15 m (Δ%5m and Δ%15m). Significant and high correlations emerged between SS15m and COD15m (r = .86, P < .0001), SS5m and SS15m (r = .92, P < .0001), SS5m and COD5m (r = .92, P < .0001), and COD5m and COD15m (r = .71, P < .0001). Δ%5m and Δ%15m showed a range of 1.2–30.0% and 34.9–59.4%, respectively. These results suggested how straight-sprint and change-of-direction performance are similar abilities in college football players, in particular when a smaller angle of the change of direction is considered. Moreover, it seems necessary to have athletes undergo tests that mimic the demands of football game, which is characterized by sprint on short distances and with changes of direction.

“…Agility motor tasks could be reactive or programmed [7]. 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].…”

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.

“…These results are confirmed by studies of Taskin, & Bicer (2015), Thakur, Mishra, & Rathore (2016) and Çñmenlñ, Koç, Çñmenlñ, & Kaçoğlu (2016), to develop appropriate training techniques for athletes. In addition, the level of development of explosive speed, speed endurance and strength affects on the intensity of the game activity of rugby players (Condello, et al, 2013).…”

Purpose: The aim of this study was to assess relationship between speed-strength abilities and technical elements of the game. Further aims was to assess the effect of specialized training on speed-strength abilities and technical elements of the game. Methods: Thirty male rugby players participated in the experiment (age 17.3±1.1 years, the body height 181.5±4.7 cm, and body weight 109.7±9.8 kg). All athletes were participants of the Ukrainian Championship under 18 age category. The study was conducted from September 2017 to June 2018. A special program of speed-strength training was developed, which contributed to the improving of technical preparedness in the competitive conditions of rugby teams. The measurement of speed-strength abilities and technical preparedness were performed before and after training programme. The relationship between speedstrength abilities and technical preparedness was assessed by Pearson correlation analysis. Results: Our study showed significant relationships between the indicators of speed-strength skills (p<0.05) and technical preparedness of rugby players (p<0.01) aged 16-18 years old. The improvement of indicators of speed-strength skills and technical preparedness under the influence of the experimental program (p<0.05) were established. Conclusions: During the speed-strength training, the effectiveness of applying the established experimental program for the development of speed-strength skills as a basis for improving the performance of technical elements for playing rugby players was proved. The test scores of the speed-strength skills significantly correlate with the indices of the technical preparedness of the athletes, justifies the necessity of their development for training of rugby players.
