    Purpose To investigate the relationship between pre-exercise blood glucose levels and performance during a 7-point incremental swim test. Methods Forty-two National level swimmers undertook a 6 Ă— 200 m incremental training set at predetermined pace, followed by an additional maximum effort swim, with each swim starting every 6:30 minutes. Subjects were asked to be one hour post-absorptive. Results were analysed in three groups based on pre-test blood glucose level; Low Blood Glucose (LBG) below 4.3; Euglycemic (EUG), 4.3 mmo/l to 6.0 mmol/l; High Blood Glucose (HBG) above 6.0 mmol/l. After each 200 m - swim, blood glucose, blood lactate, and heart rate were taken. Additionally, swim speed, stroke count, and stroke rate were recorded for each swim. Values were plotted against the swim time of each swim. Results Significant differences were observed between responses for both LBG and HBG when compared to EUG for blood glucose, lactate and heart rate (P < 0.01). Additionally, markers of swim efficiency and swim speeds were significantly affected by LBG (P < 0.01). High blood glucose appeared to be beneficial to swimming efficiency against LBG and EUG (p < 0.01). Conclusions Blood glucose levels prior to swimming had a marked effect on performance. LBG resulted in a significant reduction in the blood glucose, lactate, heart rate, and swimming efficiency responses to swimming at a range of intensities, up to maximal effort

    The relationship between VO2 max and 1200m shuttle run performance in elite academy football players

    Purpose: To investigate the relationship between VO2 max and performance in the 1200m shuttle run test in elite Premier League academy football players. Methods: Seventeen male professional outfield football players completed a laboratory based incremental treadmill test to establish vVO2 max and a field based 1200m shuttle test to estimate velocity at MAS. During the pre-season period a linear speed phase consisting of twice weekly PS exposures were conducted and each player’s PS reached during this period was established. Body composition was measured using DEXA. Results: Examining the standardized (scaled) coefficients, ASR (7.373) had the largest effect on VO2 max followed by PS (-5.568), MAS (3.604), Body Fat (-0.285) and Lean Mass (-0.185).The results suggest that the model is a significantly better predictor than a model that constantly predicts the mean VO2max value (F = 3.422, p = 0.041). Conclusions: The MAS values obtained from the 1200m shuttle test may be an appropriate assessment to consider when monitoring and individualizing high-intensity performance rather than the generic threshold of 5.5 m/s.info:eu-repo/semantics/publishedVersio

    Thermographic imaging in sports and exercise medicine: A Delphi study and consensus statement on the measurement of human skin temperature

    This is an accepted manuscript of an article published by Elsevier in Journal of Thermal Biology on 18/07/2017, available online: https://doi.org/10.1016/j.jtherbio.2017.07.006 The accepted version of the publication may differ from the final published version.© 2017 Elsevier Ltd The importance of using infrared thermography (IRT) to assess skin temperature (tsk) is increasing in clinical settings. Recently, its use has been increasing in sports and exercise medicine; however, no consensus guideline exists to address the methods for collecting data in such situations. The aim of this study was to develop a checklist for the collection of tsk using IRT in sports and exercise medicine. We carried out a Delphi study to set a checklist based on consensus agreement from leading experts in the field. Panelists (n  =  24) representing the areas of sport science (n = 8; 33%), physiology (n = 7; 29%), physiotherapy (n = 3; 13%) and medicine (n = 6; 25%), from 13 different countries completed the Delphi process. An initial list of 16 points was proposed which was rated and commented on by panelists in three rounds of anonymous surveys following a standard Delphi procedure. The panel reached consensus on 15 items which encompassed the participants’ demographic information, camera/room or environment setup and recording/analysis of tsk using IRT. The results of the Delphi produced the checklist entitled “Thermographic Imaging in Sports and Exercise Medicine (TISEM)” which is a proposal to standardize the collection and analysis of tsk data using IRT. It is intended that the TISEM can also be applied to evaluate bias in thermographic studies and to guide practitioners in the use of this technique.Published versio

    Diabetes in Sports and Exercise Medicine

    Get PDF
    This reprint focuses on exercise and physical activity research among people living with diabetes and covers a broad overview of exercise-related topics. These range from short-term effects of exercise and using daily activity measurements as vital signs in diabetes care centers to the health and fitness benefits of resistance and aerobic exercise training of all kinds, exercise prescription as a form of complementary medicine, as well as the challenges faced by children and/or adults regarding exercise programming at the community level. The goal was to cover a broad range of diabetes research, including all forms of diabetes mellitus across all life spans

    The sex gap in sports and exercise medicine research: who does research on females?

    Females are underrepresented in sports and exercise medicine research, both as authors and as research participants. The aim of this study was therefore to explore who does sports and exercise medicine research on females. All original research articles with female-only samples published in six major sports and exercise medicine journals over a 7-year period (2014–2020; n=334) were examined. Out of the 2027 authors of the articles in question, 1149 were categorized as male (56.7%) and 850 were categorized as female (41.9%; 28 [1.4%] could not be categorized). A slight majority of the articles had a female as frst author (51.5%), while the majority of the last authors were male (62.3%). Binomial tests of proportions revealed that females were overrepresented in all author roles in this sample compared to the feld at large, while chi-square tests of proportions indicated minimal variations in female authorship across the studied period. These fndings indicate that females are relatively more likely to do research on females than mpublishedVersio

    Fitness for fans: professional football and public health

    The benefits of an active life – such as improved mental health and lowered risk of type 2 diabetes, heart disease and some cancers – are well known amongst sports and exercise medicine professionals. But in the broader population, not everyone is able to realise these benefits. As part of this year’s joint BASEM/FSEM conference in Liverpool, delegates had a lively discussion about how professional football (and other sporting) clubs can help to get the population moving more. This article offers a summary and some reflections on the discussion
