• A 3-month low fat diet leads to significant lipid profile improvement in obese T2DM Saudi subjects, without substantial weight loss, and the capacity to manage a damaging high-fat meal challenge more appropriately post intervention

      Al-Disi, D; Al-Daghri, N; Khan, N; Alsaif, M; Alfadda, A; Sabico, S; Tripathi, G; McTernan, P; University of Westminster (bioscientifica, 01/03/2014)
      Current evidence highlights that dietary cholesterol, trans-fatty acids and saturated fatty acids (SFAs) are all known to increase the levels of systemic atherogenic lipoproteins and cardiovascular disease. The aim of this study was to observe the direct effect of dietary change, via a calorie-restricted diet on i) cardio-metabolic profile and ii) a high-fat meal challenge pre- and post-3-month intervention. T2DM subjects (Saudi female, age: 40.50±6.8years, BMI: 37.28±10.75 kg/m2, n=18) were given a high-fat meal pre- and post-calorie restricted diet (3 months; 500 kcal deficit/day, balanced diet with complex carbohydrate). Baseline (0 h) and post-prandial sera (1–4 h) were taken from subjects, anthropometric and biochemical data was collated at both time points. On baseline comparison of pre- and post-diet interventions, there were modest reductions in anthropometric data, BMI (P<0.001), waist (P<0.001), and waist:hip ratio (WHR; P<0.01). Baseline HDL-cholesterol increased significantly (P<0.01) whilst LDL- and total-cholesterol were significantly reduced (pre-total cholesterol: 5.13 (4.53, 5.93) vs post-total cholesterol: 4.70 (4.01, 5.14); pre-LDL cholesterol: 3.56 (3.07, 4.06) vs post-LDL cholesterol: 2.81 (2.34, 3.56), P<0.05). The findings also showed significant changes in the effects of high-fat meal intake on the metabolic profile pre- and post-diet intervention. At 4 h post-prandially, post-dietary intervention, HDL-cholesterol was 16.6% higher than pre-diet (P<0.05), whilst LDL- and total-cholesterol were 24.2 and 12% lower, respectively, than at the 4 h equivalent pre-diet (P<0.05). These findings suggest that lipid mediators associated with increased cardiometabolic risk can be quickly reversed as a result of a balanced diet, in T2DM subjects without substantial weight loss. As a result, the body is able to cope with the occasional high-fat meal insult, whilst still maintaining a reduced long-term CVD risk. As such, this is a diet that patients with T2DM may be able to adhere to more successfully, longer-term.
    • Accelerometer-based physical activity levels differ between week and weekend ways in British preschool children

      Roscoe, Clare M. P.; James, Rob S.; Duncan, Michael J.; University of Derby; Coventry University (MDPI AG, 2019-09-12)
      Participation in physical activity (PA) is fundamental to children’s future health. Studies examining the temporal pattern of PA between weekdays and weekends in British preschool children are lacking. Therefore, the aim of this study was to compare PA levels between week and weekend days for UK preschool children, using objective measurements. One hundred and eighty-five preschool children (99 boys, 86 girls, aged 4–5 years), from central England wore a triaxial accelerometer (GENEActiv) for 4 days to determine PA. The time (min) and percentage (%) of time spent in light, moderate and vigorous PA (MVPA) was determined using specific cut-points for counts per minute related to 3–5 year olds. Of the sample, none of the children met the UK recommended 180 min or more of PA per day. A significant difference (P < 0.05) was observed between the amount of time that preschool children spent in sedentary behaviours on weekdays (91.9%) compared to weekend days (96.9%). During weekdays and weekend days, 6.3% and 2.0% of time was spent in MVPA, respectively. Therefore, a substantial proportion of British preschool children’s day is spent in sedentary behaviours, with less MVPA accrued during the weekend. Regular engagement during the weekdays provides opportunities to accrue PA, which may not be present on weekend days.
    • Accelerometer-based physical activity levels, fundamental movement skills and weight status in British preschool children from a deprived area

      Roscoe, Clare M. P.; James, Rob S.; Duncan, Michael J.; University of Derby; Coventry University (Springer, 2019-04-26)
      Preschool children are recommended to participate in a minimum of 180-min physical activity (PA) per day to enhance their development and overall health. Low PA and increased obesity are thought to be linked to low mastery of fundamental movement skills (FMS) in preschool children. This study sought to investigate whether FMS influences PA levels and weight status in preschool children, in an area of low socioeconomic status. Secondary aims of this study were to determine whether gender or day of the week affected the primary outcomes. One hundred eighty-five preschool children aged 3–4 years old, participated in the study. FMS proficiency was determined using the Test of Gross Motor Development-2. PA was determined using triaxial accelerometry over a 4-day period. None of the samples met the recommended 180 min of PA. There were no significant differences in PA or weight status between preschool children with high, medium or low FMS mastery (P < 0.05). There were also no significant correlations between overall FMS and moderate to vigorous PA during the week or weekend days. Conclusion: Girls scored significantly greater at the hop, leap, and skip (locomotor skills) and the boys significantly higher at the kick (object control) (P < 0.05). There were no significant differences in PA or weight status between preschool children with high, medium, or low FMS mastery, possibly because FMS mastery had not developed to a high enough level to affect PA and FMS are considered independent of physical fitness and physical features, such as weight and height.
    • Active recovery of the finger flexors enhances intermittent handgrip performance in rock climbers

      Baláš, Jiří; Michailov, Michail; Giles, David; Kodejška, Jan; Panáčková, Michaela; Fryer, Simon; The University of Derby (Taylor and Francis, 2015-12-19)
      This study aimed to (1) evaluate the effect of hand shaking during recovery phases of intermittent testing on the time–force characteristics of performance and muscle oxygenation, and (2) assess inter-individual variability in the time to achieve the target force during intermittent testing in rock climbers. Twenty-two participants undertook three finger flexor endurance tests at 60% of their maximal voluntary contraction until failure. Performances of a sustained contraction and two intermittent contractions, each with different recovery strategies, were analysed by time–force parameters and near-infrared spectroscopy. Recovery with shaking of the forearm beside the body led to a significantly greater intermittent test time (↑ 22%, P < .05), force–time integral (↑ 28%, P < .05) and faster muscle re-oxygenation (↑ 32%, P < .05), when compared to the hand over hold condition. Further, the ratio of intermittent to continuous test time distinguished specific aerobic muscular adaptations among sport climbers (2.02), boulderers (1.74) and lower grade climbers (1.25). Lower grade climbers and boulderers produced shorter duration contractions due to the slower development of target force during the intermittent test, indicating worse kinaesthetic differentiation. Both the type of recovery and climbing discipline determined muscle re-oxygenation and intermittent performance in rock climbers.
    • Active recovery strategy and lactate clearance in elite swimmers.

      Faghy, Mark A; Lomax, Mitch; Brown, Peter I; Human Science Research Centre; University of Portsmouth; English Institute of Sport (Edizioni Minerva Medica, 2018-11-21)
      Swimming requires sustained high performance, with limited recovery between heats, recovery strategies are essential to performance but are often self-regulated and sub- optimal. Accordingly, we investigated a physiologically determined recovery protocol.
    • Affective priming of perceived environmental restorativeness

      Stevens, Paul; The Open University (2013)
      Research into the perceived restorativeness of a given environment has tended to focus on the principles of the Kaplans' Attention Restoration Theory at the expense of the affective considerations of Ulrich's psychoevolutionary model. To better understand the role of emotion, this experiment used contextual text-based primers to manipulate participants' affective state (positive or negative) prior to asking them to rate different environments using the Restorative Components Scale. Sixty-nine participants completed the web-based study, being pseudo-randomly allocated to either the positive- or negative-affect group and then rating three natural and three urban environments. Both groups rated natural environments as more restorative than urban ones, with negative-primed participants tending to give higher mean ratings for all environments. This effect was statistically significant for both the Being Away and Fascination components of perceived restorativeness for all environments, but only Fascination showed a significant interaction of the prior affective state with type of environment, a bigger effect being seen for the nature environments. Results are discussed in terms of current understanding of the interrelationship between attentional and affective processes
    • Alterations in autonomic cardiac modulation in response to normobaric hypoxia

      Giles, David; Kelly, John; Draper, Nick; University of Derby (Taylor and Francis, 2016)
      Purpose: The present study aimed to determine if autonomic cardiac modulation was influenced by acute exposure to normobaric hypoxia. Method: Ten healthy male lowland dwellers completed five block-randomised single-blinded, crossed-over acute exposures to a normobaric hypoxic environment, each separated by 24 hours’ recovery (20.3%, 17.4%, 14.5%, 12.0% and 9.8% FIO2). Supine recordings were made of arterial oxygen saturation and electrocardiogram (ECG). RR intervals from the ECG trace were analysed for time (SDNN, lnRMSSD), frequency (lnVLF, lnLF, lnHF, lnTP, LFnu, and HFnu), and nonlinear (DFA-α1 and SampEn) heart rate variability components. Results: A significant reduction in arterial SaO2 occurred with reduced FIO2, along with a rise in heart rate (Cohen’s d = 1.16, 95% Confidence Interval [2.64–6.46]), significant at 9.8% FIO2. A decrease in autonomic cardiac modulation was also found as shown by a statistically significant (at 9.8% FIO2) decrease in lnTP (d = 1.84 [1.74–1.94]), and SampEn (d = 0.98 [0.83–1.12]) and an increase in DFA-α1 (d = 0.72 [0.60–0.84]) from normoxia at 9.8% FIO2. Conclusion: The decrease in variability indicated a reduction in autonomic cardiac modulation. There appears to be a threshold ∼9.8% FIO2 (∼6000 m equiv.), below which significant alterations in autonomic control occur.
    • Ambiguity, manageability and the orchestration of organisational change: a case study of an English Premier League Academy Manager

      Gibson, Luke; Groom, Ryan; University of Derby; Manchester Metropolitan University (Taylor Francis, 2017-04-19)
      An academy is an organisational context operated by professional football clubs, governed by the rules of the English Football Association and the English Premier League. Academies provide coaching and education for youth football players aged from under 9 to under 21. The Academy Manager is responsible for the strategic leadership and operation of the club’s academy. This includes implementing the club’s philosophy, coaching and games programme, player education, and the management of academy staff. The purpose of this paper is to explore the experiences of Simon [pseudonym], an English Premier League Academy Manager, when implementing organisational change within an academy. Data were collected from a work-based diary and four in-depth semi-structured interviews. The notion of orchestration is used as an analytical frame to make sense of Simon’s experiences through the change process and further our understanding of the social complexities of organisational change in elite sporting environments.
    • An analysis of the presentation of art in the British primary school curriculum and its implications for teaching

      Hallam, Jenny; Lee, Helen A. N.; Gupta, Mani Das; Staffordshire Unviersity (Wiley, 2007)
      This paper presents an analysis of the way art is conceptualised in the British Primary School curriculum and provides an historical framework that maps an evolution of ideas that have shaped the way art is presented in the modern day Primary curriculum. In order to achieve this a Foucauldian style genealogical analysis is utilised to trace the discourses (systems of meaning) surrounding the nature of children’s artistic development and how these discourses are used in the present day British Primary Curriculum to construe art in different ways. The analysis in this paper is threefold. It explores the presentation of art in the curriculum as (i) an expressive subject, (ii) a skills based subject, (iii) a subject which focuses on art history and art appreciation. Second the teaching positions associated with each approach are identified as follows (a) the facilitator, (b) the expert and (c) the philosopher; as well as the issues teachers face when adopting these positions. Third, attention is given to how these theoretical principles might be linked to practice. In so doing this paper contributes to the debate surrounding the value of art in the Primary curriculum and the way in which the curriculum serves to shape teaching practice.

    • Arbuscular mycorrhizal community structure on co-existing tropical legume trees in French Guiana

      Brearley, Francis Q.; Elliott, David R.; Iribar, Amaia; Sen, Robin; Environmental Sustainability Research Centre, College of Life and Natural SciencesUniversity of Derby (Springer, 2016-02-10)
      Aims We aimed to characterise the arbuscular mycorrhizal fungal (AMF) community structure and potential edaphic determinants in the dominating, but poorly described, root-colonizing Paris-type AMF community on co-occurring Amazonian leguminous trees. Methods Three highly productive leguminous trees (Dicorynia guianensis, Eperua falcata and Tachigali melinonii were targeted) in species-rich forests on contrasting soil types at the Nouragues Research Station in central French Guiana. Abundant AMF SSU rRNA amplicons (NS31-AM1 & AML1-AML2 primers) from roots identified via trnL profiling were subjected to denaturing gradient gel electrophoresis (DGGE), clone library sequencing and phylogenetic analysis. Results Classical approaches targeting abundant SSU amplicons highlighted a diverse root-colonizing symbiotic AMF community dominated by members of the Glomeraceae. DGGE profiling indicated that, of the edaphic factors investigated, soil nitrogen was most important in influencing the AMF community and this was more important than any host tree species effect. Conclusions Dominating Paris-type mycorrhizal leguminous trees in Amazonian soils host diverse and novel taxa within the Glomeraceae that appear under edaphic selection in the investigated tropical forests. Linking symbiotic diversity of identified AMF taxa to ecological processes is the next challenge ahead.
    • Assessing the roles of the sender and experimenter in dream ESP research.

      Roe, Chris A.; Sherwood, Simon J.; Farrell, Louise; Savva, Louie; Baker, Ian; University of Northampton, Centre for the Study of Anomalous Psychological Processes (CSAPP) (European Journal of Parapsychology, 2007)
      This study explored the role of the sender in a dream ESP task by considering the effects of presence of a sender (sender, no sender) and the receiver’s expectancy that a sender was present. Forty participants each completed a sender and a no sender trial on consecutive nights by keeping a dream diary of all mentation they could recall when they awoke. The order of trials was randomised across participants. On no-sender nights a randomly selected video clip was played repeatedly from 2:00 until 6:30am; on sender nights a sender would also watch the clip between 6:00 and 6:30am and attempt to communicate its content. Both sender and no sender conditions produced above chance hit rates (30% and 35% respectively), but z scores for similarity ratings did not deviate significantly from chance (sender night: t(39) = 0.92, p = .18; no sender night: t(39) = 1.11, p = .14, one-tailed). There was no difference in performance in terms of sender conditions (z = -0.22, p = .41, one-tailed) or sender expectancy (z = -0.18, p = .46, one-tailed), failing to support the proposal that senders play an active role in dream ESP success. Possible improvements in the manipulation of participant expectancy are discussed.
    • Association of vitamin B12 with pro-inflammatory cytokines and biochemical markers related to cardiometabolic risk in Saudi subjects

      Al-Daghri, N.M; Rahman, S; Sabico, S; Yakout, S; Wani, K; Al-Attas, O.S; Saravanan, P; Tripathi, G; McTernan, P.G; Alokail, M.S; et al. (MDPI, 06/09/2016)
      his study aimed to examine the relationship between changes in systemic vitamin B12 concentrations with pro-inflammatory cytokines, anthropometric factors and biochemical markers of cardiometabolic risk in a Saudi population. Methods: A total of 364 subjects (224 children, age: 12.99 ± 2.73 (mean ± SD) years; BMI: 20.07 ± 4.92 kg/m2 and 140 adults, age: 41.87 ± 8.82 years; BMI: 31.65 ± 5.77 kg/m2) were studied. Fasting blood, anthropometric and biochemical data were collected. Serum cytokines were quantified using multiplex assay kits and B12 concentrations were measured using immunoassay analyzer. Results: Vitamin B12 was negatively associated with TNF-α (r = −0.14, p < 0.05), insulin (r = −0.230, p < 0.01) and HOMA-IR (r = −0.252, p < 0.01) in all subjects. In children, vitamin B12 was negatively associated with serum resistin (r = −0.160, p < 0.01), insulin (r = −0.248, p < 0.01), HOMA-IR (r = −0.261, p < 0.01). In adults, vitamin B12 was negatively associated with TNF-α (r = −0.242, p < 0.01) while positively associated with resistin (r = 0.248, p < 0.01). Serum resistin was the most significant predictor for circulating vitamin B12 in all subjects (r2 = −0.17, p < 0.05) and in children (r2 = −0.167, p < 0.01) while HDL-cholesterol was the predictor of B12 in adults (r2 = −0.78, p < 0.05). Conclusions: Serum vitamin B12 concentrations were associated with pro-inflammatory cytokines and biochemical markers of cardiometabolic risks in adults. Maintaining adequate vitamin B12 concentrations may lower inflammation-induced cardiometabolic risk in the Saudi adult population.
    • Becoming a performance analyst: autoethnographic reflections on agency, and facilitated transformational growth

      Butterworth, Andrew D.; Turner, David J.; University of Derby (Taylor and Francis, 2014-04-09)
      This paper features an autoethnographic approach in presenting and reflecting upon the story of one higher education student's rapid vocational and academic transformation. Initially an inconspicuous undergraduate student, Andrew experienced an accelerated development that catapulted him to working in elite sport performance analysis (PA) environments, within a year. PA is a sub-discipline of sports coaching that involves using the latest technological advances to influence sporting performance, through the objective analysis of performance data. This autoethnographic piece is partly Andrew’s personal reflection upon that journey towards his newfound profession, which initially grew out of his experience of a generic sports degree at a university. Through stepping out of his comfort zone, and analysing sports previously unknown to him, extraordinary progress was made, and various vocational and academic opportunities arose. The initial catalyst for this developmental journey was facilitated by coaching lecturer David, who reflects upon how Andrew’s story links to his own educational philosophies. Andrew and David explore what these stories might mean to them personally, including potential links to the metaphor of learning as becoming, and notions around the concepts of learner agency, and educational facilitation. The paper ends by exploring the theoretical frameworks that guided this paper’s structure and focus.

    • Building an integrative science for psychotherapy for the 21st-century: Preface and introduction

      Gilbert, Paul; Kirby, James; University of Derby; University of Queensland (Wiley Online Library, 2019-04-01)
      Psychotherapy is plagued with fragmentation of, models, theories and interventions. The future of psychotherapy must provide an integrative framework rooted in the expanding science of psychology, neuroscience and social contextualism. The papers in this special issue address these challenges, ranging from explorations of the implications of epigenetics, evolutionary functional analysis, interpersonal neurobiology, and importance of social relationships as physiological regulators, through to the challenges of ethnic diversities and the growing digital technologies.
    • Calibration of GENEActiv accelerometer wrist cut-points for the assessment of physical activity intensity of preschool aged children

      Roscoe, Clare M. P.; James, Rob S.; Duncan, Michael J.; Coventry University; University of Derby (Springer, 2017-07-03)
      This study sought to validate cut-points for use of wrist worn GENEActiv accelerometer data, to analyse preschool children’s (4 to 5 year olds) physical activity (PA) levels via calibration with oxygen consumption values (VO2). This was a laboratory based calibration study. Twenty-one preschool children, aged 4.7 ± 0.5 years old, completed six activities (ranging from lying supine to running) whilst wearing the GENEActiv accelerometers at two locations (left and right wrist), these being the participants’ non-dominant and dominant wrist, and a Cortex face mask for gas analysis. VO2 data was used for the assessment of criterion validity. Location specific activity intensity cut points were established via Receiver Operator Characteristic curve (ROC) analysis. The GENEActiv accelerometers, irrespective of their location, accurately discriminated between all PA intensities (sedentary, light, and moderate and above), with the dominant wrist monitor providing a slightly more precise discrimination at light PA and the non-dominant at the sedentary behaviour and moderate and above intensity levels (Area Under the Curve (AUC) for non-dominant = 0.749-0.993, compared to AUC dominant = 0.760-0.988). Conclusion: This study establishes wrist-worn physical activity cut points for the GENEActiv accelerometer in pre-schoolers.

    • Categorization of occupation in documented skeletal collections: Its relevance for the interpretation of activity-related osseous changes.

      Perréard Lopreno, Geneviève; Alves Cardoso, Francisca; Assis, Sandra; Milella, Marco; Speith, Nivien; University of Geneva; Nova University; University of Coimbra; University of Zurich; Bournemouth University; et al. (Wiley, 2013-03)
      Studies on identified skeletal collections yield discordant results about the association between osseous changes and activity. These dissonances can be ascribed to several factors: the variability of the osseous changes selected for observation, the inconsistency of their interpretative criteria and the inhomogeneous classification of occupation, here used as synonym of profession, within each study. The need to standardize the concept of occupation in its biomechanical and socio-cultural expression is currently addressed by the authors, as members of a working group created after the workshop ‘Musculoskeletal Stress Markers (MSM): limitations and achievements in the reconstruction of past activity patterns’ (Coimbra University, 2009). Within this framework, the authors reviewed the literature dedicated to entheseal changes and functional adaptation of long bones, focusing their research on studies based on European identified skeletal collections and on the criteria used in each study to classify occupations. The aim of this research was to (i) assess agreements and disagreements between authors with regard to the criteria used to categorize occupation, and (ii) highlight the steps needed to build a classification system permitting future comparisons between collections of different chronological and geographical contexts. Data from the literature were exported to a table including the assessment criteria used to classify the occupation for each profession and the assignment of specific occupations to occupational categories. Overall, our results revealed two main issues: an ambiguous historical interpretation of occupation and a marked influence of the researcher's perspective on the criteria used to classify occupations. Therefore, although the table allows basic comparisons between collections, further research is needed in order to obtain shared classifications based on each profession's specifics.
