title: The use of lower-body compression garments during high-intensity exercise performance in basketball athletes

authors: Driller, Matthew W.

abstract: This study examined the effects of lower-body compression garments worn following exercise on perceived recovery and subsequent performance in basketball athletes. In a parallel-group design, 30 recreational, male basketball athletes were randomly allocated to either a control (CON, n = 15, loose-fitting clothing) or experimental group (COMP, n = 15, compression garments) for 15h following fatigue-inducing, basketball-specific exercise. The evening exercise bout (1600-1800 h) included performance of the Basketball Exercise Simulation Test, lunge jumps, and an isometric wall sit exercise. Perceptual measures of fatigue and muscle soreness as well as physical performance tests (sprints, jumps and agility) were performed pre-exercise, post-exercise, and post-recovery (15 h following exercise). Subjective and objective measures of sleep were recorded following the exercise trial. There were non-significant (p > 0.05), unclear-trivial differences between groups for all performance measures. Perceived post-recovery fatigue (d = -1.27, large) and muscle soreness (d = -1.61, large) were significantly lower in COMP compared to CON (p < 0.05). COMP exhibited better perceived sleep quality (d = 0.42, small, p = 0.18) than CON, with an unclear difference in sleep duration between groups (p > 0.05). Wearing lower-body compression garments overnight improved perceived fatigue and muscle soreness, but had negligible effects on subsequent physical performances in basketball athletes.

title: A model for predicting the resolution of type 2 diabetes in severely obese subjects following roux-en y gastric bypass surgery

authors: Hayes, Mark Thomas

subjects: mathematical model

abstract: Background Severely obese type 2 diabetics who undergo Roux-en Y gastric bypass surgery have significant improvements in glycaemic control. Little work has been undertaken to establish the independent predictors of such resolution or to develop a predictive model. The aim of this study was to develop a mathematical model and establish independent predictors for the resolution of diabetes. Methods A consecutive sample of 130 severely obese type 2 diabetics who underwent gastric bypass surgery for weight loss from November 1997 to May 2007 with prospective pre-operative documentation of biochemical and clinical measurements was followed up over 12 months. Logistic discrimination analysis was undertaken to identify those variables with independent predictive value and to develop a predictive model for resolution of type 2 diabetes. Consecutive samples of 130 patients with body mass index (BMI)≥35 with type 2 diabetes were selected. One hundred and twenty-seven patients completed the study with a sufficient data set. Patients were deemed unresolved if (1) diabetic medication was still required after surgery; (2) if fasting plasma glucose (FPG) remained >7 mmol/L; or (3) HbA1c remained >7%. Results Resolution of diabetes was seen in 84%, while diabetes remained but was improved in 16% of patients. Resolution was rapid and sustained with 74% of those on medication before surgery being able to discontinue this by the time of discharge 6 days following surgery. Five preoperative variables were found to have independent predictive value for resolution of diabetes, including BMI, HbA1c, FPG, hypertension and requirement for insulin. Two models have been proposed for prediction of diabetes resolution, each with 86% correct classification in this cohort of patients. Conclusions Type 2 diabetes resolves in a very high percentage of patients undergoing gastric bypass surgery for severe obesity. The key predictive variables include preoperative BMI, HbA1c, FPG, the presence of hypertension and diabetic status.

title: A Critical Tiriti Analysis of the Treaty Statement From a University in Aotearoa New Zealand

authors: Hamley, Logan

abstract: Universities in Aotearoa New Zealand have been placed under the spotlight for claims of systemic racism. Following the claims made in relation to the University of Waikato in 2020 and University of Otago in 2022, universities have the responsibility to create an inclusive environment where systemic racism is dismantled, to meaningfully partner with Māori to construct a model for decolonisation, and to enhance the academic experience of Māori staff and students by weaving in mātauranga Māori into existing teaching and research practices. The University of Waikato progresses ahead of other universities in its attempt to fulfil Te Tiriti o Waitangi commitment through the introduction of the Treaty Statement. In this paper, the Treaty Statement is used as a case study to identify how universities articulate bicultural commitments. To do so, our team (consisting of Māori and tauiwi scholars) performed a critical Tiriti analysis comprising five phases to investigate the degree of alignment of the statement with Te Tiriti. The desktop analysis showed poor engagement with most Te Tiriti elements. The analysis evaluation of “good” (more than satisfactory) was measured for the consideration of “Māori exercising equitable citizenship”. This article concludes with recommendations of how universities can strengthen their practices to live up to Te Tiriti aspirations.
