Establishing the reliability of a novel battery of range of motion tests to enable evidence-based classification in Para Swimming

© 2018 Elsevier Ltd. Objectives: To evaluate the reliability of swimming-specific range of movement tests developed in order to permit evidenced-based classification in the sport of para swimming. Design: Test-retest intra- and inter-examiner reliability. Setting: International Swimming training camps and university exercise science departments. Participants: 42 non-disabled participants (mean age 23.2 years) and 24 Para swimmers (mean age 28.5 years). Main outcome measures: Intra- and inter-examiner reliability of a battery of novel active range of motion tests. Results: Good to excellent intra-examiner reliability was found for the majority (32/34) of tests in non-disabled participants (ICC = 0.85–0.98). SEM values ranged from 1.18° to 6.11°. Similarly, good to excellent inter-examiner reliability was found for the majority (35/42) of tests in non-disabled participants (ICC = 0.85–0.98). SEM values range from 0.73° to 6.52°. Para swimmers exhibited significantly reduced range of motion compared to non-disabled participants. Conclusions: The large majority of ROM tests included in this novel battery were reliable both within and between examiners in non-disabled participants. The tests were found to differentiate between non-disabled participants and Para swimmers with hypertonia or impaired muscle power

Playing exposure does not affect movement characteristics or physiological responses of elite youth footballers during an intensified period of competition.

This is an Accepted Manuscript of an article published by Taylor & Francis in Science and Medicine in Football on 08/05/18, available online: https://www.tandfonline.com/doi/full/10.1080/24733938.2018.1470664This study investigated the effect of playing time on physiological and perceptual responses to six, 60 min matches played over five days. Thirty youth football players (age = 14.1 ± 0.4 years; body mass = 57.4 ± 12.9 kg; stature 169.3 ± 7.7 cm) were grouped into low (<250 min; LPG, n = 18) and high (≥250 min; HPG, n = 12) match exposure groups and monitored daily for lower body power and perceived wellness. GPS technology was used to assess match running demands in total distance (m•min-1), low (<13 km•h-1) and high (≥13 km•h-1) speed running categories. Hypothesis based testing and effect sizes (ES) were used to analyse data. The HPG performed moderately more total distance (103.7 ± 10.4 cf. 90.2 ± 19.7 m•min-1, P = 0.03; ES=0.74 ± 0.63) and high speed running (26.7 ± 6.6 cf. 20.3 ± 6.5 m•min-1, P = 0.01; ES=0.87 ± 0.6) than the LPG across all six matches. Differences of a small magnitude were observed between groups for lower body power (P = 0.08; ES =0.59 ± 0.8) and perceived wellness (P = 0.09; ES=0.42 ± 0.4) which were both higher in the HPG. Youth football players appear well equipped to deal with intensified period of competition, such as those experienced in tournaments, irrespective of match exposure

Motivational sensitivity of outcome-response priming: Experimental research and theoretical models

Outcome-response (O-R) priming is at the core of various associative theories of human intentional action. This is a simple and parsimonious mechanism by which activation of outcome representations (e.g. thinking about the light coming on) leads to activation of the associated motor patterns required to achieve it (e.g. pushing the light switch). In the current manuscript, we review the evidence for such O-R associative links demonstrated by converging (yet until now, separate) strands of research. While there is a wealth of evidence that both the perceptual and motivational properties of an outcome can be encoded in the O-R association and mediate O-R priming, we critically examine the integration of these mechanisms and the conditions under which motivational factors constrain the sensory O-R priming effect. We discuss the clinical relevance of this O-R priming mechanism, whether it can satisfactorily account for human goal-directed behaviour, and the implications for theories of human action control

Cognitive style and entrepreneurial drive of new and mature business owner managers

Purpose The purpose of this study was to investigate whether cognitive style and entrepreneurial drive are important for identifying individuals who have the potential to become successful entrepreneurs, and for discriminating between owner-managers operating in mature and early stages of venture creation and growth. Design/Methodology Data were obtained from entrepreneurs involved in early (n = 81) and mature (n = 50) stages of venture creation and growth. Instruments used in the study include the Cognitive Style Index which measures the analytic-intuitive dimension of cognitive style and the Carland Entrepreneurial Index which measures entrepreneurial drive. Findings Entrepreneurs tend to be more intuitive and less analytic than non-entrepreneurs. The more intuitive entrepreneurs exhibited higher levels of drive towards entrepreneurial behaviour. Those operating in the early stages of venture creation and growth exhibited higher entrepreneurial drive than those operating in mature stages. Implications Cognitive style may be useful for identifying individuals who have the potential to become successful entrepreneurs. The finding that more intuitive entrepreneurs exhibited higher levels of entrepreneurial drive suggests that cognitive style may also be helpful for discriminating between micro-entrepreneurs and macro-entrepreneurs. Originality/Value There is a paucity of convincing research on individual differences as a way of distinguishing entrepreneurs from non-entrepreneurs, even though it is believed to be central to understanding the field. This study is the first of its kind to consider the implications of both entrepreneurial drive and cognitive style for entrepreneurs operating in the mature and start-up stages of venture creation and growth
