Effect of bilberry juice on indices of muscle damage and inflammation in runners completing a half-marathon: a randomised, placebo-controlled trial.

Background: Emerging evidence indicates that fruits rich in polyphenols may attenuate exercise-induced muscle damage and associated markers of inflammation and soreness. This study was conducted to determine whether bilberry juice (BJ), which is particularly rich in polyphenols, reduces markers of muscle damage in runners completing a half marathon. Methods: A total of 21 recreationally trained runners (age 30.9 ± 10.4 y; mass 71.6 ± 11.0 kg; M=16; F=5) were recruited to a single blind, randomised, placebo-controlled, parallel study. Participants were block randomised to consume 2 x 200 ml of BJ or energy-matched control drink (PLA) for 5 d before the Sheffield Half Marathon, on race day, and for 2 days post-race. Measurements of delayed onset muscle soreness (DOMS), muscle damage (creatine kinase; CK) and inflammation (c-reactive protein ; CRP) were taken at baseline, pre-race, post-race, 24 h post-race and 48 h post-race. The effect of treatment on outcome measures was analysed using magnitude-based inferences based on data from 19 participants; 2 participants were excluded from the analyses because they did not provide samples for all time points. Results: The half marathon caused elevations in DOMS, CRP and CK. BJ had a possibly harmful effect on DOMS from pre-race to immediately post-race (11.6%, 90% CI ± 14.7%), a likely harmful effect on CRP from pre-race to 24 h post-race (mean difference ES 0.56, 90% CI ± 0.72) and a possibly harmful effect on CRP from pre-race to 48 h post-race (ES 0.12, 90% CI ± 0.69). At other time points, the differences between the BJ and PLA groups in DOMS and CRP were unclear, possibly trivial or likely trivial. Differences in the changes in CK between BJ and PLA were unclear at every time point other than from baseline to pre-race, where BJ had a possibly harmful effect on reducing muscle damage (ES 0.23, 90% CI ± 0.57). Conclusion: Despite being a rich source of antioxidant and anti-inflammatory phytochemicals, BJ evoked small to moderate increases in exercise-induced DOMS and CRP. Further larger studies are required to confirm these unexpected preliminary results

Implementing an e-learning Masters programme for Practice Development

Introduction – The need for more effective person centred care has been propositioned for a number of years (Dewar and Nolan 2013; McCormack, Dewing and McCance, 2011; Dewing, 2004) and Practice Development (PD) has been viewed as one way to embed this into organisational culture (Manley, Sanders, Cardiff and Webster, 2011). More recently multiple policy reports echo this call (Age UK, 2012; Willis Commission on Nursing, 2012; Parliamentary Health Service Ombudsman, 2011). Joint work between the Department of Nursing and England Centre for Practice Development at Canterbury Christ Church University has validated an innovative Masters level programme in Practice Development, utilising workplace and e-learning approaches to facilitate creativity in the work setting. Aim: This paper will briefly describe the programme and then explore the experiences and challenges of implementing a work based and e-learning Masters Practice Development and Innovation programme. Approach: Practice Development is built on the key principles of person-centredness, shared values and vision, transforming individuals and culture through active learning, facilitation and engagement (McCormack, Manley, Titchen 2013). Thus, the approach to the Masters programme reflects these principles and utilises facilitation methods to enable practice development to transform the learner and work setting. As part of this process we, as lecturers, have been developing our own values and beliefs and expanded our knowledge and skills so that we can positively impact on the learner experience and work as learning partners. The programme is, therefore, evolving to embody these principles and enable learners to incorporate them into practice. The programme is built around ten core Practice Development/Innovation principles and the process of Active Learning, which will be expanded on in the presentation. Our vision is to make this programme accessible to regional, national and international learners. The work-based and e-learning approaches make this achievable but bring challenges to ensure that the programme reflects the principles of Practice Development from a distance. This is further complicated by facilitating a range of learners from diverse clinical areas, experiences and cultures who have often been exposed to traditional forms of learning. Thus, facilitating the learners to engage with the material, and incorporate it into their own practice setting, has led to careful consideration of materials for the learners to access. As the programme is progressing areas are emerging that need to be thoughtfully considered and addressed to ensure development of learning. Considerations: Initial themes starting to emerge are: increasing lecturer knowledge and skills around both Practice Development and different tools for e-learning, learners previous experience of facilitation and willingness to take responsibility for their own learning, challenges of promoting active learning approaches online , enabling achievement of Masters level learning outcomes with a distance approach, new ways of working for individuals plus the organisational views around supporting learners in practice. These require both lecturers and learners to be motivated to learn and devote time to engage with material and processes. However, it also requires lecturers and learners to make choices and reflect on activities to assess the relevance and usefulness to their situation. The programme encourages learners to be creative and examine issues differently which takes time to engage with and progress. Conclusion: Evaluation of this programme is in its infancy. A key learning point is that transforming practice through Practice Development and innovation in the workplace also involves transforming University views on learning, engagement and creativity

Minimal muscle damage after a marathon and no influence of beetroot juice on inflammation and recovery

This study examined whether beetroot juice (BTJ) would attenuate inflammation and muscle damage following a marathon. Using a double blind, independent group’s design, 34 runners (~16 previous marathons completed) consumed either BTJ or an isocaloric placebo (PLA) for 3 days following a marathon. Maximal isometric voluntary contractions (MIVC), countermovement jumps (CMJ), muscle soreness, serum cytokines, leucocytosis, creatine kinase (CK), high sensitivity C-reactive protein (hs-CRP) and aspartate aminotransferase (AST) were measured pre, post, and on the 2 days after the marathon. CMJ and MIVC were reduced after the marathon (P0.05). Muscle soreness was increased in the day after the marathon (BTJ; 45±48 vs. PLA; 46±39 mm) and had returned to baseline by day 2, irrespective of supplementation (P=0.694). Cytokines (Interleukin-6; IL-6, interleukin-8, tumour necrosis factor-α) were increased immediately post-marathon but apart from IL-6 had returned to baseline values by day 1 post. No interaction effects were evident for IL-6 (P=0.213). Leucocytes increased 1.7 fold after the race and remained elevated 2 days post, irrespective of supplement (P<0.0001). CK peaked at 1 day post marathon (BTJ: 965±967 & PLA: 1141±979 IU·L-1) and like AST and hs-CRP, was still elevated 2 days after the marathon (P<0.05); however, no group differences were present for these variables. Beetroot juice did not attenuate inflammation or reduce muscle damage following a marathon, possibly because most of these indices were not markedly different from baseline values in the days after the marathon

Influence of a montmorency cherry juice blend on indices of exercise-induced stress and upper respiratory tract symptoms following marathon running—a pilot investigation

Background: Prolonged exercise, such as marathon running, has been associated with an increase in respiratory mucosal inflammation. The aim of this pilot study was to examine the effects of Montmorency cherry juice on markers of stress, immunity and inflammation following a Marathon. Methods: Twenty recreational Marathon runners consumed either cherry juice (CJ) or placebo (PL) before and after a Marathon race. Markers of mucosal immunity secretory immunoglobulin A (sIgA), immunoglobulin G (IgG), salivary cortisol, inflammation (CRP) and self-reported incidence and severity of upper respiratory tract symptoms (URTS) were measured before and following the race. Results: All variables except secretory IgA and IgG concentrations in saliva showed a significant time effect (P < 0.01). Serum CRP showed a significant interaction and treatment effect (P < 0.01). The CRP increase at 24 and 48 h post-Marathon was lower (P < 0.01) in the CJ group compared to PL group. Mucosal immunity and salivary cortisol showed no interaction effect or treatment effect. The incidence and severity of URTS was significantly greater than baseline at 24 h and 48 h following the race in the PL group and was also greater than the CJ group (P < 0.05). No URTS were reported in the CJ group whereas 50 % of runners in the PL group reported URTS at 24 h and 48 h post-Marathon. Conclusions: This is the first study that provides encouraging evidence of the potential role of Montmorency cherries in reducing the development of URTS post-Marathon possibly caused by exercise-induced hyperventilation trauma, and/or other infectious and non-infectious factors

What water sources and irrigation systems can be best utilized to continue regenerating the native flora at Pūtaringamotu Riccarton Bush?

GEOG309: Research for Resilient Environments and Communities (School of Earth and Environment, University of Canterbury)• Pūtaringamotu Riccarton Bush is a 7.8-hectare ngahere (forest) in Christchurch that is highly valued by the local community and hapu, Ngāi Tūāhuriri. • The surrounding landscape has been drained due to urbanization and, in 1998, an irrigation system was installed to ensure survival of the forest. The Riccarton Bush Trust have asked us to investigate how this irrigation system may be improved. • The research aimed to explore what water sources and irrigation systems could be best utilized to continue regenerating the native flora at Riccarton Bush. This involved determining whether variation in vegetation types and soil moisture across Riccarton Bush should be considered in the design of a new irrigation system. • A literature review was conducted that focused on irrigation methods, native plant water needs, and the historical context of the site. • Vegetation surveys at 13 field sites used a 5 x 5 m quadrat method to identify plant species and assess their abundance and maturity. • Manual soil moisture samples were collected across 13 sites and analysis using ASTM DD2216 methods. • TOMST TSM-4 soil moisture probes were calibrated and installed at field sites. These collected data over a month for analysis. • A total of 32 plant species were identified, emphasizing both native species and the differences between mature plants and saplings. • The relationship between soil moisture and vegetation was insufficient to draw any clear conclusions. • The research indicates due to regeneration occurring and minimal changes in vegetation type compared to historical data, the current irrigation system appears sufficient to support continued regeneration of the forest. • Research limitations included the limited number of field sites chosen and the inability to collect data year-round to account for seasonal soil moisture variations. • Our recommendations for future research include updating the irrigation system with a focus on water conservation and incorporating supplementary water sources such as roof stormwater and potential spring water

Biographical learning: a process for promoting person-centredness in nursing

Background: This paper explores biographical approaches to nurses’ learning. It builds on previous PhD research to consider the effects of such approaches, drawing on the experiences of learners who have recently completed biographical study, in their own words. Aims and objectives: The aim of the paper is to make sense of different forms of learning. The objectives are to identify how autobiographical approaches that involve people learning from their life stories can engage people to exert agency, or ownership, in their own lives by taking control of their learning plans. Design: This longitudinal study started with the first group of learners undertaking a biographical preparation module on an Applied BSc Health and Social Care programme. Methods: Research relating to nurses’ learning is considered, including a Swiss perspective, as well as the validity of the biographical approach to developing knowledge. The learners share stories of their learning in order to develop understanding and new insights into their own lives and those of others. Results: Different dimensions of learning including learning about self, learning to make a difference and processes of repair are revealed through the learners’ narrations. Conclusions: Engaging biographically, to make sense of different forms of learning, appears to be beneficial to more person-centred working. Implications for practice: •Introducing biographical elements into courses of study can benefit learners by helping them to make sense of who they are as learners and practitioners •Co-creating compelling spaces of learning can facilitate learners to exert agency within their own lives as well as help others to learn. By exerting agency we mean taking ownership of the learning revealed through the biographical work and taking it forward in positive ways to enhance person-centred care

Beetroot juice is more beneficial than sodium nitrate for attenuating muscle pain after strenuous eccentric-bias exercise

The aim of this study was to compare the effects of beetroot juice (BTJ) and a nitrate only drink (sodium nitrate; SN) on indices of exercise-induced muscle damage (EIMD). Thirty recreationally active males consumed either BTJ (n = 10), a nitrate-matched SN drink (n = 10), or an isocaloric placebo (PLA; n = 10) immediately and at 24 and 48 h after performing 100 drop jumps. To assess muscle damage, maximal isometric voluntary contractions (MIVCs), countermovement jumps (CMJs), pressurepain threshold (PPT), creatine kinase (CK), and high-sensitivity C-reactive protein (hs-CRP) were measured before, immediately after and at 24, 48, and 72 h following the drop jumps. BTJ and SN increased serum nitric oxide, which peaked at 2 h post-ingestion (136 ± 78 and 189 ± 79 µmol·L-1, respectively). PPT decreased in all groups postexercise (P = 0.001), but was attenuated with BTJ compared with SN and PLA (P = 0.043). PPT was 104% ± 26% of baseline values at 72 h after BTJ, 94% ± 16% after SN, and 91% ± 19% after PLA. MIVC and CMJ were reduced following exercise (-15% to 25%) and did not recover to baseline by 72 h in all groups; however, no group differences were observed (P > 0.05). Serum CK increased after exercise but no group differences were present (P > 0.05). hsCRP levels were unaltered by the exercise protocol (P > 0.05). These data suggest that BTJ supplementation is more effective than SN for attenuating muscle pain associated with EIMD, and that any analgesic effects are likely due to phytonutrients in BTJ other than nitrate, or interactions between them
