title: Calf muscle abilities are related to sprint performance in male Rugby Union players

authors: Hébert-Losier, Kim

abstract: Objectives: To examine the strength of the relationship between plantarflexor power and strength-endurance metrics and 10-m sprint times in male Rugby Union players. A secondary aim was to examine the strength of the relationship within calf muscle metrics. Design: Observational cross-sectional correlational. Setting: Field-based. Participants: Sixteen male Rugby Union players in the National Provincial Championship. Main outcome measures: Participants completed three single-leg calf muscle tests: bodyweight power, weighted power, and strength-endurance. Data were recorded using the Calf Raise application. Three-to-four days later, average and best 10-m sprint performances were collected using timing lights. Results: There were large significant correlations between 10-m sprint performances (average and best times) and calf muscle power (weighted) and strength-endurance (total displacement and work) metrics (r = −0.503 to −0.628). There were large significant correlations between bodyweight and weighted power, weighted power and strength-endurance (total displacement and work), and most strength-endurance metrics (r = 0.520 to 0.943). Conclusions: Our findings emphasise the importance of triceps surae muscle power and strength-endurance for maximal-effort accelerations and sprint performances in Rugby Union. Our data indicate that weighted power and total work from strength-endurance tests are the most useful metrics for further investigation in the context of short sprints and acceleration.

title: Investigating the contextual requirements of the Juster Scale

authors: Parackal, Mathew

subjects: Juster Scale

abstract: Researchers have employed the Juster Scale to collect purchase probability data with notable success. Reviewing the Juster Scale studies, however, has revealed that there is considerable variation in its per¬formance. Some of these variations appeared to be caused by the context in which the Juster Scale has been presented to respondents. This paper discusses three factors that influence the context of the Juster Scale and reports the results of a study that attempted to standardise its contextual requirements.
The results substantiate further the Juster Scale's satisfactory performance in collecting purchase probability data.

title: Learning in later life: a bicultural perspective from Aotearoa/New Zealand

authors: Findsen, Brian

abstract: This article is concerned with how learning in later life has been constructed and practised by the two most numerous ethnic groups in Aotearoa/New Zealand, Pākėhā (Europeans) and Māori (Indigenous people). It is argued that learning is heavily influenced by historic features of interaction between these two groups; Pākehā as the dominant cultural and economic group and Māori as subordinate. While contemporary perspectives are necessarily interpreted in the light of historical trends and events, fresh interpretations of what constitutes biculturalism in this country allow for more nuanced understanding of possibilities for and obstacles to older adult learning/education. Themes from lifelong learning are analysed with special reference to older people’s learning, the consequences of Māori sovereignty on pedagogy and trends identified for older adult education. Two linked case studies of Pākehā and Māori older adult education in a New Zealand university are described to illustrate complexities and tensions in provision in a bicultural context.
