title: Recognition of foot strike pattern in Asian recreational runners.

authors: Patoz, Aurélien

subjects: asymmetry

abstract: Close to 90% of recreational runners rearfoot strike in a long-distance road race. This prevalence has been obtained from North American cohorts of runners. The prevalence of rearfoot strikers has not been extensively examined in an Asian population of recreational runners. Therefore, the aim of this study was to determine the prevalence of rearfoot, midfoot, and forefoot strikers during a long-distance road race in Asian recreational runners and compare this prevalence to reported values in the scientific literature. To do so, we classified the foot strike pattern of 950 recreational runners at the 10 km mark of the Singapore marathon (77% Asian field). We observed 71.1%, 16.6%, 1.7%, and 10.6% of rearfoot, midfoot, forefoot, and asymmetric strikers, respectively. Chi-squared tests revealed significant differences between our foot strike pattern distribution and those reported from North American cohorts (P < 0.001). Our foot strike pattern distribution was similar to one reported from elite half-marathon runners racing in Japan (Fisher exact test, P = 0.168). We conclude that the prevalence of rearfoot strikers is lower in Asian than North American recreational runners. Running research should consider and report ethnicity of participants given that ethnicity can potentially explain biomechanical differences in running patterns.

title: An ecological study of Chinese privet (Ligustrum sinense Lour.) in the Waikato Region

authors: Grove, E.

subjects: New Zealand

abstract: Chinese privet (Ligustrum sinense) has naturalised across the Waikato region invading lowland native forest and wetland habitat. This shrub has the ability to form a dense canopy or subcanopy and appears to exclude other native species from establishing in the understorey. Chinese privet seedlings were found in abundance underneath privet canopy, where they grow slower than when invading a new site yet are able to succeed adult plants and continually occupy a site. Chinese privet seedlings establish readily under intact native canopy but are more prolific in disturbed high light environments. Fruit is produced in abundance and is dispersed by birds particularly beneath perch sites, which limits seed dispersal over open ground. Chinese privet seedlings appear to be palatable to stock, but rapidly out-compete and dominate regenerating native species when grazing pressure is removed. A short-lived seedbank, six months to one year viability, suggests that the removal of adult plants will quickly reduce the number of seedlings establishing. This invasive shrub is a serious weed in south-eastern USA where it is well established and would appear to have similar potential in New Zealand to form vast, dense thickets with very low floristic diversity.

title: “It is about enabling Tino Rangatiratanga and Mana Motuhake”: An analysis of submissions on the Pae Ora (Healthy Futures) Bill 2021 endorsing a Māori health authority

authors: Edmonds, Moengaroa

subjects: Health Equity

abstract: Indigenous leadership in healthcare is one way for Indigenous peoples to exercise sovereignty over their health. In Aotearoa New Zealand, the establishment of the Māori Health Authority (MHA) was grounded in a decades-long imperative to address Māori health inequities and operationalise te Tiriti o Waitangi within the health system. However, the populist National-led coalition government formed in November 2023 included the abolishment of the MHA in their first 100-day plan and eventually disestablished it in February 2024. This study analysed 155 public group submissions on the Pae Ora (Healthy Futures) Bill made in 2021 and representing health professionals, iwi, hapū, and community groups. Core themes endorsing the MHA as a statutory entity included honouring te Tiriti, advocating for Māori-led solutions to health inequities, decolonising health systems, and affirming Indigenous rights. The political decision to remove the MHA is antithetical to the explicit endorsement statements made by an overwhelming majority of group submitters with expertise in health organisational structures and healthcare provision. Our study has implications for future local and international research in documenting counter-narratives for Indigenous struggles in health systems.
