Laboratory versus field testing in cricket bowling: a review of current and past practice in modelling techniques

In cricket bowling, the reconstruction of elbow angle data is of utmost importance to the bowling versus throwing argument. This paper reviews system and modelling errors inherent in three-dimensional reconstruction processes with respect to the elbow extension tolerance set by the International Cricket Council. An understanding of these factors will enable more informed decisions about the choice of in-field versus laboratory testing in the calculation of elbow extension during bowling in cricket. Although there is a paucity of objective data related to in-field and laboratory testing, biomechanists must be guided by the greater accuracy of opto-reflective than video-based systems and so testing, at least for the present, should be conducted in a laboratory setting.     

Validity and Reliability of Three Self-Report Instruments for Assessing Attainment of Physical Activity Guidelines in University Students

The purpose of this study was to compare the validity and reliability of three short physical activity self-report instruments to determine their potential for use with university student populations. The participants (N = 155; 44.5% male; 22.9 ± 5.13 years) wore an accelerometer for 9 consecutive days and completed a single-item measure, the a brief two item measure and the International Physical Activity Questionnaire—Short Form questionnaires on day 1 and 9. Correlations between self-reported and accelerometer derived moderate-to-vigorous physical activity levels were moderate for the International Physical Activity Questionnaire—Short Form, while poor for the single-item measure and the a brief two item measure. The agreement level was high with the International Physical Activity Questionnaire—Short Form (77.4%) and moderate for both the single-item measure (45.2 %) and a brief two item measure (44.5 %). The intraclass correlations between the two administrations were moderate to strong across all measures (0.52–0.70) in 133 participants. The International Physical Activity Questionnaire—Short Form is the most suitable of these three self-report instruments for use with this population due to higher correlations and levels of agreement with accelerometry.     

Questioning the no-touch discourse in physical education from a children's rights perspective

In this paper we question the rationality of ‘no-touch policies’ and offer an alternative approach to the matter of physical contact between teachers and students in the context of physical education (PE) in schools. Earlier research has drawn attention to how a discourse of child protection is starting to affect how physical contact is viewed in PE practice. The avoidance of intergenerational touch is increasingly justified by referring to the children's rights agenda. Here, arguments for ‘no-touching’ are linked to children's right to be protected from harm. In the paper we explore a children's rights-based viewpoint that supports the use of and need for physical contact in PE teaching by developing theoretical and practice-based arguments. An alternative children's rights perspective, based on rights theorising, is used to formulate the theoretical argument. Interviews with 16 PE teachers about their experiences of physical contact in their pedagogical work form the practice-based arguments. The two arguments provide a way of looking at intergenerational touch in education from the vantage point of children's human right to develop to their full potential, which can support a need for physical touch in pedagogical situations.
