Role Satisfaction Mediates the Relation between Role Ambiguity and Social Loafing among Elite Women Handball Players
2010
The aims of the study were to develop a questionnaire on self-reported social loafing (SRSLQ), and then to examine its relations with role ambiguity and role satisfaction in a sample of 110 women handball players competing at the elite level in Norway. Structural equation modeling analyses indicated that the SRSLQ was a psychometrically sound measure. In line with the expectations, role satisfaction fully mediated the positive relation between role ambiguity and self-reported social loafing: The more players experienced role ambiguity, the less satisfied they were with their role in the team, and the more social loafing they reported.
Making Every "Point" Count: Identifying the Key Determinants of Team Success in Elite Men’s Wheelchair Basketball
2019
Wheelchair basketball coaches and researchers have typically relied on box score data and the Comprehensive Basketball Grading System to inform practice, however, these data do not acknowledge how the dynamic perspectives of teams change, vary and adapt during possessions in relation to the outcome of a game. Therefore, this study aimed to identify the key dynamic variables associated with team success in elite men’s wheelchair basketball and explore the impact of each key dynamic variable upon the outcome of performance through the use of binary logistic regression modelling. The valid and reliable template developed by Francis, Owen and Peters (2019) was used to analyse video footage in S…
The impact of school-day variation in weight and height on National Child Measurement Programme body mass index-determined weight category in Year 6 …
2011
Background In England, the National Child Measurement Programme (NCMP) annually measures the weight and height of Year 6 school children (age 10–11 years). While measurement protocols are defined, the time of measurement within the school day is not. This study examined the impact of school-day variation in weight and height on NCMP body mass index (BMI)-determined weight category in Year 6 children. Methods Standing height and weight were measured in morning and afternoon sessions in 74 children, boys (n= 34; height: 141.16 ± 7.45 cm; weight: 36.48 ± 9.46 kg, BMI: 18.19 ± 3.98 kg/m2) and girls (n= 40; height: 144.58 ± 7.66 cm; weight: 42.25 ± 11.29 kg; BMI: 19.97 ± 3.98 kg/m2) aged 11 ± 0.…

Older adults who have previously fallen due to a trip walk differently than those who have fallen due to a slip
2014
Studying the relationships between centre of mass (COM) and centre of pressure (COP) during walking has been shown to be useful in determining movement stability. The aim of the current study was to compare COM-COP separation measures during walking between groups of older adults with no history of falling, and a history of falling due to tripping or slipping. Any differences between individuals who have fallen due to a slip and those who have fallen due to a trip in measures of dynamic balance could potentially indicate differences in the mechanisms responsible for falls. Forty older adults were allocated into groups based on their self-reported fall history during walking. The non-faller …
Kako budući stručnjaci u sportu, tjelovježbi i tjelesnome odgoju percipiraju tjelesni izgled pretile djece
2010
Anti-fat bias has been previously identified amongst practising obesity health care specialists, physical education (PE) teachers and students of exercise science and PE in samples in the USA and New Zealand. The present research investigated the perceptions of the physical self of ‘fat’ versus ‘normal-weight’ children held by 167 students studying sport exercise and PE related programmes in higher education in England. Onesample t-tests identified that the sample held negative perceptions towards ‘fat’ children (identified by subscale mean scores that were significantly different from the subscale mean of 2.5 that would identify equivocal perception between ‘fat’ and ‘normal-weight’ childr…

Age and Grip Strength Predict Hand Dexterity in Adults.
2015
In the scientific literature, there is much evidence of a relationship between age and dexterity,\ud where increased age is related to slower, less nimble and less smooth, less coordinated\ud and less controlled performances. While some suggest that the relationship is a direct consequence\ud of reduced muscle strength associated to increased age, there is a lack of research\ud that has systematically investigated the relationships between age, strength and\ud hand dexterity. Therefore, the aim of this study was to examine the associations between\ud age, grip strength and dexterity. 107 adults (range 18-93 years) completed a series of hand\ud dexterity tasks (i.e. steadiness, line tracking…

Development and Initial Validation of the Humor Climate in Sport Scale
2021
In sport teams, humor is an essential element that influences communication processes, and plays an important role in group dynamics. Despite this, no current instrument is presented in the literature to measure humor climate in sport teams. Therefore, the current study presents the development and initial validation of the Humor Climate in Sport Scale (HCSS). The aim was to assess content, structural and concurrent validity of the developed instrument, and to examine differential item functioning (DIF) as a function of sex. Three different phases were completed in this study. The first phase involved focus groups (n= 5) that explored humor as communication in a team sport context. In phase…
The Influence of Collective Behavior on Pacing in Endurance Competitions
2015
A number of theoretical models have been proposed in recent years to explain pacing strategies observed in individual competitive endurance events. These have typically related to the internal regulatory processes that inform the making of decisions relating to muscular work rate. Despite a substantial body of research which has investigated the influence of collective group dynamics on individual behaviors in various animal species, this issue has not been comprehensively studied in individual athletic events. This is somewhat surprising given that athletes often directly compete in close proximity to one another, and that collective behavior has also been observed in other human environme…
Preferred Coach Leadership Behaviour in Elite Soccer in Relation to Success and Failure
2008
Multidimensional models of leadership in sport suggest that in order to maximize performance there should be congruence between the actual coaching behaviour and behaviours preferred by players. This study examined the preferred coaching leadership behaviours in prolonged periods of perceived success and failure in eighty-eight elite soccer players in Norway using the Leadership Scale for Sport (LSS). The three preferred behaviours were Positive Feedback, Training & Instruction, and Democratic Behaviour in both scenarios. All preferred behaviours (except Autocratic Behaviour) were higher in the unsuccessful scenario (p <.01). Negative relationships existed between age/experience and…

2014
Semi-structured interviews were conducted with twenty team sport athletes representing a range of different sports with the aim of investigating their views relating to social loafing in training and competition. General themes investigated and subsequent content analysis highlighted factors that promote or reduce the extent of social loafing. Determinants of self-loafing were grouped according to three distinct categories: Group processes; Task characteristics and Individual perceptions. Social loafing among others was perceived to be prevalent in both the training and competition scenarios with more examples of social loafing provided in the training situation. The signs of social loafin…
