Öğe Effect of Coach Encouragement on the Psychophysiological and Performance Responses of Young Tennis Players(Mdpi, 2019) Kilit, Bülent; Arslan, Erşan; Akca, Firat; Aras, Dicle; Soylu, Yusuf; Clemente, Filipe Manuel; Knechtle, BeatThis study aimed to compare the effects of coach encouragement during the on-court tennis training drills (OTDs) on the psychophysiological and performance responses of young tennis players. Twenty-five young male tennis players (14.0 +/- 0.3 years of age) performed six bouts of each of the four common OTDs; Star, Suicide, Box and Big X (30:60 s; 1:2 work to rest ratio). The heart rate (HR) and total distance covered were monitored using two portable multivariable integrated 10 Hz GPS monitoring devices during all OTDs, and the rating of perceived exertion (RPE-10) and short form Physical Activity Enjoyment Scale (PACES) values were determined after each OTDs bout. The results demonstrated that OTDs with coach encouragement induced significantly higher psychophysiological and performance responses compared to OTDs without coach encouragement (p < 0.05). The results of this study confirm that coach encouragement improves the intensity, performance and physical enjoyment level during OTDs. These findings might inform training practices in youth tennis players in order to improve tennis performance.Öğe Effects of different stretching methods on speed and agility performance in young tennis players(Elsevier France-Editions Scientifiques Medicales Elsevier, 2019) Kilit, Bülent; Arslan, Erşan; Soylu, YusufPurpose. - The purpose of this study was to investigate the acute effect of different stretching methods on speed and agility performance in young tennis players according to conditioning level. Methods. - Twenty-six young tennis players participated in this study voluntarily. Stretching methods were divided into five groups: static, dynamic, static + dynamic, dynamic + static, and control (no-stretching). The protocols included 8-min warm-up, a 3-min rest, 30-s stretching program (except for the no-stretching group), a 2-min rest, followed by the T-drill agility and 20-m sprint (with 10-m split times) test. Stretching protocols consisted of 6 different stretching exercises for 6 lower muscle groups. Results. - Dynamic and static + dynamic stretching methods induced significant differences in the 10-m acceleration, 20-m sprint and agility test time compared with static and static + dynamic stretching protocols (P < 0.05). Dynamic and no-stretching methods also showed significant difference between good and moderate performers compared with static, static + dynamic and dynamic + static stretching protocols (P < 0.05). Conclusion. - We concluded that the acute effect of static stretching had a negative effect on agility and sprint performances. This study suggest that dynamic and static + dynamic stretching might be use for the performing better performance in acceleration, speed and agility skills during the warm-up session in young tennis players.

Twenty-eight recreationally active young adults (age: 21.1 ± 1.6 years) were randomly assigned to either the self-paced HIIT (n = 14) or the MICT (n = 14) group training protocol. The HIIT consisted of two 12-24 x 30 seconds of high-intensity runs interspersed by 30 seconds of recovery. The MICT completed 24-48 minutes of continuous running. Before and after the 8-week interventions the following tests were completed: Maximum oxygen consumption (VO2max) estimated from the Yo-Yo Intermittent Recovery Test level 1 (YYIRTL-1), repeated sprint ability (RSA), 10-30-m sprint test, change of direction test (T-drill), countermovement jump (CMJ) and squat jump (SJ), and triple hop distance test (THD). Training rating of perceived exertion (RPE) and physical activity enjoyment scale (PACES) were assessed during the training programme. The HIIT resulted in greater improvement in YYIRTL-1, VO2max, RSA and T-drill performances compared to the MICT. Furthermore, RPE and PACES values were higher in the HIIT than the MICT. This study suggested that self-paced HIIT may be a more effective training regime to improve aerobic fitness with greater physical enjoyment in recreationally active young adults. © 2021 Institute of Sport.

Thirty-two male players (age: 14.5 ± 0.5 years of age) were randomly divided into SSGs group (n = 16) and HIIT group (n = 16) training methods thrice per week for 6 weeks. The players in the SSGs group performed two 5–8 min of 2 vs. 2 with 2 min rest periods, while the players in HIIT performed 12–18 min of runs at intensities (90 to 95%) related to the velocity obtained in the 30-15 intermittent fitness test (IFT). Pre-testing and post-testing sessions involved assessments of Yo-Yo Intermittent Recovery Test level 1, 30-15 intermittent fitness test, 5 and 30 m sprint times, vertical jump height, repeated sprint ability, defensive and offensive agility, and technical skills. The SSGs group demonstrated significantly higher agility-based technical responses in terms of the control dribbling and shooting skills (d = 1.71 vs. 0.20, d = 1.41 vs. 0.35, respectively) compared with the HIIT group. Conversely, the HIIT induced greater improvements in 30 m sprint times (d = 3.15 vs. 0.68). These findings provided that SSGs in youth basketball players may allow similar positive physical adaptations to HIIT, with an extra advantage of improving technical skills while improving enjoyability. © 2022, MDPI.

The study included 602 adolescent athletes ages 14.6 2.7 (female: 377, age=14.7 2.3 and male: 225, age=14.6 3.4) and 24.7 7.0 (female: 215, age= 24.0 6.4 and male: 200, age= 25.3 7.2) and 415 adult athletes (age= 25.3 7.2). The Brunel Mood Scale consists of six sub-dimensions and comprises 24-item assessments in adult (BRUNEL-TY) and adolescent (BRUNEL-TE) forms. According to the findings of the study, the fit index values of the BRUNEL-TY form were 2/sd=3.00; P.01, SRMR=.070, RMESA=.068, CFI=.92, NNFI=.90, while the fit index values of the BRUNEL-TE form were 2/sd=3.01; P.01, SRMR=.047, RMESA=.058, CFI=.94, NNFI. According to the findings, the Turkish version of the Brunel Mood Scale had acceptable psychometric performance and could be utilized as a valid and reliable assessment instrument in the setting of Turkish adult and adolescent athletes.Öğe Short-term effects of on-field combined core strength and small-sided games training on physical performance in young soccer players(Institute of Sport, 2021) Arslan, Erşan; Soylu, Yusuf; Clemente, Filipe Manuel; Hazir, T.; İşler, A.K.; Kilit, BülentThis study aimed to compare the effects of 6-weeks combined core strength and small-sided games training (SSGcore) vs. small-sided games (SSG) training on the physical performance of young soccer players. Thirty-eight amateur soccer players (age: 16.50 ± 0.51 years) were randomly assigned to either a SSGcore (n = 20) or a SSG group (n = 18). The SSGcore group performed upper and lower body core strength exercises combined with SSG including 2-, 3- and 4-a-sided soccer games third a week. The SSG group performed only the SSG periodization. Baseline and after the 6-week training period the Yo-Yo Intermittent Recovery Test level 1 (YYIRTL-1), 5-20-m sprint test, countermovement jump (CMJ), squat jump (SJ), triple-hop distance (THD), zigzag agility with ball (ZAWB) and without ball (ZAWOB), three corner run test (TCRT) and Y-balance test. The SSGcore group demonstrated meaningful improvements in 20 m sprint time (SSGcore: -9.1%, d = 1.42; SSG: -4.4%, d = 0.76), CMJ (SSGcore: 11.4%, d = 2.67; SSG: -7.7%, d = 1.43), SJ (SSGcore: 12.0%, d = 2.14; SSG: 5.7%, d = 1.28), THD (SSGcore: 5.0%, d = 1.39; SSG: 2.7%, d = 0.52) and TCRT (SSGcore: -3.7%, d = 0.69; SSG: -1.9%, d = 0.38). Furthermore, the SSGcore group demonstrated meaningfully higher improvement responses in both leg balance score (d = ranging from 2.11 to 2.75) compared with SSG group. These results suggest that the inclusion of core strength training to a SSG periodization is greatly effective to improve speed and strength-based conditioning in young soccer players. © 2021 Institute of Sport.

Twenty-four soccer players (aged 14.63 ± 0.71 years) were randomly divided into SSGs + HIIT (n = 12) and HIIT + SSGs (n = 12) for 6 weeks. The SSGs consisted of two 4–16 min rounds of 2, 3, and four-a-side games with 2 min of passive resting, whereas the HIIT consisted of 6–10 min of high-intensity runs at varying intensities (from 90 to 100%). Pre-test and post-test elements included a 5–30 m sprint test, countermovement jump test, zigzag agility test with the ball and without the ball, repeated sprint ability test, speed dribbling ability test, three-corner run test, and Yo-Yo Intermittent Recovery Test level 1. Both combined training interventions produced similar improvements in physical performance and technical responses (p ? 0.05, d values ranging from 0.40 to 1.10). However, the combined HIIT + SSGs training produced meaningfully lower perceived exertion (p = 0.00, d = 2.98) and greater physical enjoyment (p = 0.00, d = 4.28) compared with the SSGs + HIIT intervention. Furthermore, the SSGs + HIIT group showed a higher training load than those from the HIIT + SSGs group for all weeks (p ? 0.05, d values ranging from 1.36 to 2.05). The present study’s results might be used by coaches and practitioners to design training programmes for youth soccer players. © 2021 by the authors.

In this regard, competitive tennis players require not only well-developed aerobic endurance and anaerobic capacity, but also technical and tactical skills to achieve high levels of performance during training and matches. The aim of this review was to investigate the demands of competitive tennis match play in terms of physiological responses, time-motion characteristics and match analysis. Three sport science journal databases PubMed, ISI Web of Knowledge and SPORT Discus were screened for papers published until May 2018. The following keywords were used in various combinations with tennis: notational analysis, physiological demands, simulated match, time-motion, and match characteristic. In this review, studies had to meet follow inclusion criteria: cross sectional or longitudinal design, case control studies, or experimental studies electronically published in English. All studies demonstrated high methodological quality. This review presents a useful synthesis of all research into match performance in tennis, including the investigation of the internal and external load of the tennis match play and helps to guide for future research.
