Human runners exhibit a least variable gait speed

This study characterises the relationship between gait variability and speed in runners using data from trunk accelerations in each axis.

Twelve participants of varying fitness ran on the treadmill with three sessions of six randomly ordered self-selected speeds. A VO_2max test was conducted on the fourth session. Running gait was tracked with inertial sensors. The occurrence of a mid-range speed was analysed for the anterior–posterior, vertical and lateral directional coefficient of variation (CV) of root mean square (RMS) acceleration data.

One participant with noisy gait signals was omitted. The results show all remaining participants consistently showed significant quadratic U-shaped relationships between vertical RMS CV acceleration and speed. Neither anterior–posterior nor lateral RMS CV acceleration were clearly related to speed. These least variable gait speeds were similar to estimates of optimal speed derived from minimum cost of transport with speed.

In conclusion, there exists a mid-range speed for each runner with the least variable gait in the vertical direction, and this occurred significantly more often than would be expected by chance (P < 0.05). However, there are no prominent patterns for the anterior–posterior and lateral directions. This finding supports anecdotal evidence from runners and coaches concerning gait consistency.     

The experience of captaincy in professional sport: The case of elite professional rugby

The captain is perceived to be an important member of the leadership structure within teams across many professional sports. However, while there is a general acceptance that this is the case, there is very little research exploring the role and associated demands at an elite level. As a result, the aim of this study was to explore the captaincy experiences of elite professional rugby union captains. The participants were eight male captains purposefully sampled for this study. Participants were interviewed individually to gain an understanding of each participant’s captaincy experiences. The data were thematically analysed using interpretative phenomenological analysis. Nine super-ordinate themes emerged in the study: role, skills, requirements, challenges, the coach, development, experience, context, and approach. Results suggest that the captaincy role is broader than previously highlighted, particularly at the elite level. Also, the study highlights inconsistencies in the selection of captains and a lack of formal developmental support for elite rugby captains. As a result, future research should explore the development of specific evidence-based approaches to captain selection and development.     

Predicting performance in the first grade with the first-grade screening test

Items of the First Grade Screening Test (FGST) were rationally grouped into four subscales: Self-Concept, Visual-Motor, Reasoning, and Vocabulary. Prefirst grade subject scores were compared with later first grade teacher ratings. Agreement ranged from 64 to 70% on the subscales. An overall screening strategy utilizing subscate scores and a total score cutoff point yielded 82.5% agreement with teacher ratings of overall school performance.     

The special features of sport: A critical revisit

In the world of contemporary sport it is commonly claimed that at its elite end at least, sport's management is complex because the product it delivers to participants and fans is so idiosyncratic. This claim is accompanied by the view that while professional sport is in large part just another form of business, it has a range of special features that demand a customised set of practices to ensure its effective operation. This article aims to re-examine this view in the light of sport's commercial and socio-cultural developments over the last decade. It initially proposes that while both business and sport are concerned with widening market share, building profits, and strengthening brands, the presumption that sport has a monopoly over the delivery of intense emotional experiences, tribal belonging, and strong interpersonal relationships, is difficult to defend. The article concludes that while sport's economic and social progress has created an industry that is built around complex bureaucracies that turn over many thousands of millions of dollars every year, it has also created a more diverse and heterogeneous system of structures and experiences that are difficult to conflate to a handful of neat special features.     

Gender differences in the perceived impact that athlete leaders have on team member emotional states

ABSTRACT

Emotional contagion has been recognized as a variable influencing individual behaviour and team functioning. In particular, leaders within the team have been suggested to have a significant impact on their teammates through the expression of their emotions. As a result, the aim of this study was to provide greater insight into how different athlete leaders impact the emotional state of their team members, and whether gender differences existed in these relationships. Participants were 295 university student-athletes (200 male and 95 female) recruited from four universities in the UK. Data were collected in a two-step process. First, a voting/rating procedure was conducted within team to identify dominant task, motivational, social and external leaders. Then, participants completed the emotional contagion subscale of the Measure of Empathetic Tendency to rate the impact different athlete leaders had upon their emotional state. A MANOVA was conducted to explore gender differences in reported emotional susceptibility by leadership role. Subsequent ANOVAs highlighted significant differences between leadership role scores for female participants only. The results suggest that female athletes are more susceptible to emotional influence than male athletes. Furthermore, female athletes experienced a greater variation in the perceived emotional influence of different leadership roles in the team.     

Teachers using learning styles: Torn between research and accountability?

The proliferation of instruments reporting learning/cognitive style with school pupils is of particular interest, because most research on them focuses on applications in higher education, training and the adult workplace, where criticisms of their integrity, reliability and validity have been significant. This study examines two such popular instruments in highly effective schools in England, UK. Neither instrument demonstrated reasonable internal consistency or results according with theoretical constructs. Concerns about their usefulness in these contexts are explored. Reasons provided by faculty for their use were: face validity; external inspection; professional accountability; institutional policy; the legacy from initial training; established classroom practice.
