ABSTRACT

The aims of this study were (i) to characterise the acceleration demands of two different formats of small-sided game (SSG), i.e., 4v4 + goalkeepers (4v4 + GK) and 8v8 + goalkeepers (8v8 + GK); (ii) to analyse the correlation between performance in power-based tests and acceleration-based physical loading during the two different SSG formats and (iii) to analyse the neuromuscular-induced fatigue. Eighteen adult male footballers participated in the study (20.7 ± 1.0 years, 178 ± 5 cm and 71.4 ± 2.1 kg). Baseline measurements were obtained from countermovement jumps, 15 s repeated jumps and 5 and 15 m sprints. A total of 36 min was analysed for each SSG (4v4 + GK: two sets of 3 × 6 min, and 8v8 + GK: 2 × 18 min). Heart rate, blood lactate, perceived exertion and movement pattern (GPS) were analysed. Distances covered by very-high-intensity activities and very-high-speed running were lower in 4v4 + GK than in 8v8 + GK (effect sizes (ES) = ?0.69 ± 0.67 and ?1.04 ± 0.67, respectively; very likely), while accelerations and decelerations were higher in 4v4 + GK than in 8v8 + GK (ES = 1.13–1.52; almost certainly). Blood lactate concentrations were higher (ES = 1.40 ± 0.58; almost certainly) and players perceived themselves to be more tired (ES = 0.80–2.31; almost certainly) after 4v4 + GK than after 8v8 + GK. Sprint ability in 5 and 15 m tests decreased (ES = 0.87 ± 0.58 and 0.89 ± 0.58, respectively; almost certainly) only after 4v4 + GK. This SSG format appeared more demanding in relation to repetitions and fatigue development of muscle power-based actions than 8v8 + GK. It may therefore be logical to use the former type of SSG to target development of power-related football actions.  相似文献   

The relationship between game-based performance indicators and developmental level in junior Australian football: Implications for coaching

Identifying performance differences between juniors at different stages of a talent pathway may assist with the development of prospective talent. This study investigated the relationship between game-based performance indicators and developmental level in junior Australian football (AF). Players were categorised into 2 groups according to developmental level; U16 and U18. Physical and technical skill performance indicators were collated for all U16 (n = 200) and U18 (n = 244) participants of their respective 2014 national championships. Data were acquired from all 28 games (12 U16, 16 U18); resulting in 1360 player observations (568 U16, 792 U18). Microtechnology and a commercial provider facilitated the quantification of 15 performance indicators. Generalised estimating equations (GEEs) modelled the extent to which these performance indicators were associated with developmental level. The GEE model revealed that “contested marks” and “contested possessions” had the strongest association with the U16 level, while “total marks” and “clearances” had the strongest association with the U18 level. The remaining performance indicators were not developmentally discriminant. These results indicate that there are distinctive features of gameplay more associated with the U16 and U18 levels in AF. Coaches may wish to consider these results when constructing training drills designed to minimise developmental gaps.  相似文献   

Early Football and the Emergence of Modern Soccer: A Reply to Tony Collins     

Peter Swain 《国际体育史杂志》2016,33(3):251-271

This paper seeks to defend one part of what has become known as the ‘revisionist’ account of the historiography of football in nineteenth-century England. In so doing, it responds to the critique by Tony Collins in his article ‘Early Football and the Emergence of Modern Soccer’ between 1840 and 1880, calling into question the reliance in his arguments of what he describes as ‘legal organized games’ as the only measure of a football culture outside of the public schools. His classification of small-sided games of football as an ‘informal leisure practice or folk custom’ is also interrogated and found wanting. Alternatively, further evidence is presented from 1860 of football games played in a variety of forms, usually alongside other sports, and mainly on church, works’ or schools’ outings, at rural fetes, galas and celebrations, or as street or casual football, the latter taking place in meadows, fields, and greens. Importantly, these were predominantly small-sided games and are, arguably, the ones closest to Association football, as it was codified in 1863, and constituted a broad, tenacious, and increasingly visible football culture that existed amongst the general population across mid-century uninfluenced by the public schools and public school boys.  相似文献   

The development and validation of the Interpersonal Support in Physical Activity Consultations Observational Tool     

Peter C. Rouse  Joan L. Duda  Nikos Ntoumanis  Kate Jolly  Geoffrey C. Williams 《European Journal of Sport Science》2016,16(1):106-114

This study describes the development and psychometric characteristics of an observational instrument that examines four aspects of interpersonal support (or lack of) provided during physical activity (PA) promotion consultations (i.e., Autonomy Support, Involvement, Structure and Interpersonal Control), as identified by Self-determination Theory (SDT). The reliability and validity of the Interpersonal Support in Physical Activity Consultations Observational Tool (ISPACOT) were examined within an exploratory randomised control trial. Recorded consultations (N = 42) conducted by qualified PA advisors (N = 14) at 13 leisure centres across the West Midlands (UK) were rated. Intra-class correlation coefficients (ICC) indicated moderate to high inter-rater reliability for overall interpersonal support (0.80), and the Autonomy Support (0.74), Involvement (0.73) and Structure (0.91) dimensions, but low reliability for Interpersonal Control (0.35). The advisors, who conducted PA promotion consultations that were rated as low in their interpersonally supportive features, were perceived by their clients as being less supportive (F(1,10) = 5.0, p <.05). Ratings on the ISPACOT differentiated advisors who were trained in SDT principles and those who were not. Overall, the findings provided preliminary evidence for the reliability and convergent validity of the ISPACOT.  相似文献   

Training the inspiratory muscles improves running performance when carrying a 25 kg thoracic load in a backpack     

Mark A. Faghy  Peter I. Brown 《European Journal of Sport Science》2016,16(5):585-594

Load carriage (LC) exercise in physically demanding occupations is typically characterised by periods of low-intensity steady-state exercise and short duration, high-intensity exercise while carrying an external mass in a backpack; this form of exercise is also known as LC exercise. This induces inspiratory muscle fatigue and reduces whole-body performance. Accordingly we investigated the effect of inspiratory muscle training (IMT, 50% maximal inspiratory muscle pressure (P_Imax) twice daily for six week) upon running time-trial performance with thoracic LC. Nineteen healthy males formed a pressure threshold IMT (n?=?10) or placebo control group (PLA; n?=?9) and performed 60?min LC exercise (6.5?km?h^–1) followed by a 2.4?km running time trial (LC_TT) either side of a double-blind six week intervention. Prior to the intervention, P_Imax was reduced relative to baseline, post-LC and post-LC_TT in both groups (pooled data: 13?±?7% and 16?±?8%, respectively, p?P_Imax increased +31% (p?TT (+18%, p?P_Imax at each time point was unchanged (13?±?11% and 17?±?9%, respectively, p?>?.05). In IMT only, heart rate and perceptual responses were reduced post-LC (p?p?相似文献

Examining student-designed games through Suits' theory of games     

Ashley Casey  Peter Hastie  Steve Jump 《Sport, Education and Society》2016,21(8):1230-1248

This paper documents how a unit of student-designed games can create a more meaningful version of physical education (PE) for disengaged students, a version that enhances the educational legitimacy of the subject matter by affording it worth in and of itself rather than being justified for other, extrinsic or instrumental reasons. Furthermore, it seeks to develop new knowledge relating to the conduct of game instruction within PE, by using Suits' theory of games. Drawing on Suits' theory, we develop a conceptual model that is intended to represent the hierarchical processes that occur in gameplay through student-designed games. This model is then tested via examination of the experiences of a cohort of teachers and their year 10 students from a mixed secondary school in the greater London area. From our discussions with the students, it is argued that the key focus of the games that these students were used to playing was the need to ‘play the game well’. By contrast, we suggest that it is possible to provide more meaningful experiences to students if a more philosophically driven and less efficiency-driven approach to games is taken, following Suits' lead more closely. By exploring the loop between and around lusory means, lusory goals and constitutive rules (the aspects of Suits' theory that have been shown to represent student-designed games), students engage with a more meaningful games experience than simply playing the game well. This ‘new’ approach to games may offer counterbalance to the ideological tendencies now emphasized in countries and contexts that celebrate instrumental outcomes of performative PE and sport rather than affording worth in and of itself to the curriculum’s subject matter.  相似文献
