title: Measures of Rowing Performance

authors: Smith, Tiaki Brett

subjects: performance measures

abstract: Accurate measures of performance are important for assessing competitive athletes in practical and research settings. We present here a review of rowing performance measures, focusing on the errors in these measures and the implications for testing rowers. The yardstick for assessing error in a performance measure is the random variation (typical or standard error of measurement) in an elite athlete's competitive performance from race to race: ∼1.0% for time in 2000 m rowing events. There has been little research interest in on-water time trials for assessing rowing performance, owing to logistic difficulties and environmental perturbations in performance time with such tests. Mobile ergometry via instrumented oars or rowlocks should reduce these problems, but the associated errors have not yet been reported. Measurement of boat speed to monitor on-water training performance is common; one device based on global positioning system (GPS) technology contributes negligible extra random error (0.2%) in speed measured over 2000 m, but extra error is substantial (1-10%) with other GPS devices or with an impeller, especially over shorter distances. The problems with on-water testing have led to widespread use of the Concept II rowing ergometer. The standard error of the estimate of on-water 2000 m time predicted by 2000 m ergometer performance was 2.6% and 7.2% in two studies, reflecting different effects of skill, body mass and environment in on-water versus ergometer performance. However, well trained rowers have a typical error in performance time of only ∼0.5% between repeated 2000 m time trials on this ergometer, so such trials are suitable for tracking changes in physiological performance and factors affecting it. Many researchers have used the 2000 m ergometer performance time as a criterion to identify other predictors of rowing performance. Standard errors of the estimate vary widely between studies even for the same predictor, but the lowest errors (~1-2%) have been observed for peak power output in an incremental test, some measures of lactate threshold and measures of 30-second all-out power. Some of these measures also have typical error between repeated tests suitably low for tracking changes. Combining measures via multiple linear regression needs further investigation. In summary, measurement of boat speed, especially with a good GPS device, has adequate precision for monitoring training performance, but adjustment for environmental effects needs to be investigated. Time trials on the Concept II ergometer provide accurate estimates of a rower's physiological ability to output power, and some submaximal and brief maximal ergometer performance measures can be used frequently to monitor changes in this ability. On-water performance measured via instrumented skiffs that determine individual power output may eventually surpass measures derived from the Concept II.

title: “Mate Ni Vula”, “Masina”, “Vaʻine Fakahēʻaho”, “Eikura” Pacific sports women’s knowledge and experiences of menstruation

authors: Gibbons, Agatha

abstract: Pacific women's interest and participation in sports have increased rapidly throughout the decades. Recently, many have become competitive across a range of sports at regional, national, and international levels. Yet very little research is focused on Pacific sportswomen’s experiences, or how their cultural identities shape their performance, health, and well-being needs. This thesis focuses on Pacific sportswomen’s experiences of menstruation, and in so doing, makes an important contribution to both literature on Pacific sportswomen, and research on menstruation in sport. Research on sportswomen’s experiences of menstruation has grown significantly over recent years, but most of this research is conducted by white women on white sportswomen, with findings then generalized to all sportswomen. This thesis identifies a gap in literature, and the risks of excluding sportswomen’s cultural identities, practices, and values from research, policy, and practices focused on menstruation in sport. 
Adopting a Masi methodology, this project included three methods: a survey of 206 Pacific sportswomen; Talanoa sessions with 21 Fijian sportswomen, and interviews with 16 Pacific sportswomen living in Aotearoa New Zealand.  This project aimed to listen to, learn from, and amplify sportswomen's experiences and their understandings of menstruation, cultural beliefs, and the taboos that influence their menstrual experiences. This is a thesis with publication; some chapters are published articles, and others are manuscripts undergoing review. First, the thesis systematically identifies the gap in the literature with a scoping review of research focused on menstruation in sport, that shows that % of research ignores women’s cultural or ethnic identities. This chapter identifies the need for more culturally responsive research methods and culturally safe practices from sports and health professionals working with sportswomen from diverse backgrounds. Following this, results from the survey are presented, highlighting the diversity of cultural knowledge and practices associated with menstruation across the Pacific the survey also reveals the different cultural stigmas, beliefs, taboos, traditions, menstrual health, and sports performance of elite Pacific sportswomen. The following two chapters focus on findings from Fijian sportswomen, and then Pacific sportswomen living in Aotearoa New Zealand, with both amplifying the voices and experiences of Pacific sportswomen and their challenges of gaining culturally informed menstrual health information and support in sporting environments. These chapters describe how culture intersects with gender and other key variables (i.e., socio-economic considerations), and how these influence sportswomen’s experiences of menstruation.  
Ultimately, this research makes an important contribution to research on menstruation in sport, highlighting the need for culturally responsive methodologies and approaches in research and practice. It provides new and current cultural knowledge that can be used to improve the health, performance, and social support structures for Pacific sportswomen. This knowledge can expand sports and health providers' understanding of Pacific sportswomen's culturally specific needs, knowledge, and values concerning menstruation. Finally, this research supports the development of sport in the Pacific by providing cultural knowledge on how to engage Pacific sportswomen in safe, respectful, and constructive conversations around menstruation in sport.

title: Evidence of swarm intelligence in collective cultures: Identifying the use of the swarm goal directive of productivity in Pacific organisation systems as well as getween genders

authors: Arun, Natalie M.

subjects: Maori

abstract: Intrigued by the existence of societies outside that of the human population, scientists have ventured to study social aggregations within insects to seek insights on effective colonizing. The most popular of these social aggregations are colonies of ants and bees. In studying these groups of social insects researchers have developed algorithms loosely termed swarm intelligence that increase work efficiency within businesses and other social organizations (Bonabeau & Meyer, 2001). A subsequent proliferation of research in surrounding fields has allowed for investigation of key variables that improve work on a global scale (Bonabeau & Meyer, 2001). James Kennedy (1999), an initiator of swarm research, has suggested that there is a high correlation between systems that rely on each other for information and greater task accomplishment.
