The Relationship Between Pistol Olympic Shooting Performance, Handgrip and Shoulder Abduction Strength

Introduction There are many factors that affect performance in Olympic shooting. Elite shooters are capable of reaching extreme levels of precision and accuracy. In female air pistol shooting, the best shooters often reach scores as high as the current world record (393/400), or in other words success of 98.2% hitting the ten points score. Considering that the maximum score of a shot (10 points) represents accuracy within a circle of a diameter of 11.5 mm ± 0.1 mm from a shooting distance of 10 meters, failure or important loss in performance due to

Spanish Elite Soccer Reserve Team Configuration and the Impact of Physical Fitness Performance

the professional level ( Mills et al., 2012 ). This may also reflect the shift from a market-based solution to the problem of finding skilled labor towards another one based on internal hierarchical arrangements (i.e., grow-your-own policies) ( Bourke, 2003 ). This option can be even more interesting in countries like Spain, where the poor financial wealth of the whole system ( Barajas and Rodríguez, 2013 ) has increased the differences between the teams of the Spanish Liga. Soccer academies consider both the training process to facilitate the highest performance

Physical Performance Differences Between Starter and Non‐Starter Players During Professional Soccer Friendly Matches

a high intensity ( Bradley et al., 2009 ; Di Salvo et al. 2009). A large number of studies have reported on the specific energetic and physical performance demands of elite soccer players, including the effects of positional variation, using time motion analysis ( Bradley et al., 2009 ; Di Salvo et al., 2009 ; Rampinini et al., 2007). For example, central midfielders were reported to cover more total distance than any other positions with the wide midfielders and fullbacks also displaying superior high‐intensity efforts during a match ( Bradley et al., 2009 ; Di

Influence of Contextual Variables on Performance of the Libero Player in Top-Level Women’s Volleyball

Introduction Sports performance analysis provides objective information based on a series of performance indicators ( O’Donoghue, 2010 ). Given the dynamic nature of the sport, a detailed analysis of these indicators is needed because of the influence external conditions, known as situational variables such as the quality of opposition, the game period, match status, etc. ( Gómez et al., 2013 ), or internal features such as the play role, the game phase, etc., may have on such indicators. As to the dynamics of volleyball, various game phases may be identified

Predicting Competition Performance in Short Trail Running Races with Lactate Thresholds

, 2012 ). However, data on performance predictions in trail running are still relatively scarce ( Balducci et al., 2017 ; Ehrström et al., 2017 ; Fornasiero et al., 2017 ; Scheer et al., 2018 a) and this may partly be due to the complexity of trail running with its prolonged uphill and downhill running sections, over uneven terrain, placing different physiological and biomechanical demands on the musculature and the human body compared to road running ( Degache et al., 2013 ; Giandolini et al., 2016 ; Giovanelli et al., 2016 ).

The Impact of Rule Modifications on Elite Basketball Teams’ Performance

Introduction Interpretation of sports rules is a tool widely used by coaches in order to improve performance of their teams and athletes ( Gracia et al., 2014 ; Hill-Haas et al., 2010 ). Sports rule modifications, such as in court dimensions or the number of active players, may cause an improvement in athletes’ physical conditioning ( Cormery et al., 2008 ; Klusemann et al., 2012 ; Mikołajec et al., 2012), as well as technical (Delextrat and Martinez, 2014) and tactical skill levels (Sampaio and Maçãs, 2012). The effect of rule modification has always been

Development and Validation of a Checklist to Assess Proficient Performance of Basketball Straight Speed Dribbling Skill

Introduction Reliable tools of assessment are crucial for physical educators, sport coaches, and other professionals concerned with improving movement performance. Assessing sport skills allows for grading children with different proficiency levels, predicting future performance and evaluating sports and physical education programs ( Currell and Jeukendrup, 2008 ; Strand and Wilson, 1993 ; Strumbelj and Erčulj, 2014 ). Basketball is one of the most played team sports worldwide (International Olympic Committee IOC; Wierike et al. 2015 ), but, surprisingly
