Sprinting Ability as an Important Indicator of Performance in Elite Long-Distance Runners

Ryo Yamanaka, Hayato Ohnuma, Ryosuke Ando, Fumiya Tanji, Toshiyuki Ohya, Masahiro Hagiwara, and Yasuhiro Suzuki

seasonal best time of elite junior long-distance runners was correlated with the cross-sectional area of the psoas major, which is directly related to sprinting ability. 9 Moreover, Tucker et al 10 showed a variation in running velocity during a world-record performance and reported that the final

Effects of Ball Drills and Repeated-Sprint-Ability Training in Basketball Players

Martina A. Maggioni, Matteo Bonato, Alexander Stahn, Antonio La Torre, Luca Agnello, Gianluca Vernillo, Carlo Castagna, and Giampiero Merati

properly with strong evidence-based support. Ball-drills and repeated sprint ability training have begun to be widely used by coaches to improve physical fitness. 7 Ball-drills training consists of a series of short duration matches with a small number of players and which replicate match-like technical

Short-Term Creatine Supplementation and Repeated Sprint Ability—A Systematic Review and Meta-Analysis

Mark Glaister and Lauren Rhodes

& Ren, 1989 ), it is reasoned that creatine supplementation could enable better recovery between successive sprints, resulting in an overall improvement in performance (or repeated sprint ability; Glaister et al., 2006 ; Yquel et al., 2002 ). However, the results of studies examining the effects of

M. Biceps Femoris Long Head Architecture and Sprint Ability in Youth Soccer Players

Paul Ritsche, Thomas Bernhard, Ralf Roth, Eric Lichtenstein, Martin Keller, Sabrina Zingg, Martino V. Franchi, and Oliver Faude

study to investigate the BFlh architecture and sprint ability in youth soccer players at the age of 12–15 years. We aimed to investigate the differences in BFlh anatomical cross-sectional area (ACSA), FL, and pennation angle (PA), and the sprint ability in circa-pubertal soccer players of different age

Repeated-Sprint Training With Blood-Flow Restriction Improves Repeated-Sprint Ability Similarly to Unrestricted Training at Reduced External Loads

James R. Mckee, Olivier Girard, Jeremiah J. Peiffer, Daniel J. Hiscock, Kristen De Marco, and Brendan R. Scott

Sustaining performance over a series of short-duration efforts (≤10 s) interspersed with brief recovery periods (≤60 s; ie, repeated-sprint ability [RSA]) is crucial for team-sport competition. 1 , 2 Repeated-sprint training (RST) can improve RSA by combating physiological factors contributing to

Effects of Warm-Up Training on Psychomotor Vigilance and Repeated-Sprint Ability of Professional Soccer Referees: A Pilot Study

Mateu Busquets-Ferrer, Francisco Tomás González-Fernández, Filipe Manuel Clemente, and Alfonso Castillo-Rodriguez

 al., 2002 ). Moreover, in terms of physical performance and repeated-sprint ability (RSA) of SRs, a strong correlation has been established between sprinting skills and a high-intensity performance level ( Haugen et al., 2013 ). In this vein, the physical condition of the athlete plays a relevant role in

Repeated-Sprint Ability: Where Are We?

Brian Dawson

Repeated-sprint ability (RSA) is now well accepted as an important fitness component in team-sport performance. It is broadly described as the ability to perform repeated short (~3–4 s, 20–30 m) sprints with only brief (~10–30 s) recovery between bouts. Over the past 25 y a plethora of RSA tests have been trialed and reported in the literature. These range from a single set of ~6–10 short sprints, departing every 20–30 s, to team-sport game simulations involving repeating cycles of walk-jog-stride-sprint movements over 45–90 min. Such a wide range of RSA tests has not assisted the synthesis of research findings in this area, and questions remain regarding the optimal methods of training to best improve RSA. In addition, how RSA test scores relate to player “work rate,” match performance, or both requires further investigation to improve the application of RSA testing and training to elite team-sport athletes.

Assessing Youth Sprint Ability–Methodological Issues, Reliability and Performance Data

Michael C. Rumpf, John B. Cronin, Jon L. Oliver, and Michael Hughes

The primary purpose of this paper was to provide insight into the methodological issues and associated reliability of assessments used to quantify running sprint ability in youth athletes aged 8–18 years. Over-ground sprinting was the most reliable and common used choice of assessment to measure sprint performance of youth. In addition, the performance data of those athletes over distances ranging from 5 to 40 meters was collated from 34 published articles and tabulated with regards to the athlete’s chronological age. Torque or nonmotorized treadmills have been used to quantify sprint performance in youth with acceptable reliability, this technology providing deeper insight into sprint kinetics and kinematics; however there is limited performance data on youth using the torque and the nonmotorized treadmill. It is suggested that future research should use this technology in youth to better understand changes associated with growth, maturation and training.

Effects of Playing Surface on Physical, Physiological, and Perceptual Responses to a Repeated-Sprint Ability Test: Natural Grass Versus Artificial Turf
