    On June 6, 2019, the Polish Archives of Internal Medicine published an interesting article by Szczerbiński et al,1 entitled “Efficacy of family history, genetic risk score, and physical activity in assessing the prevalence of type 2 diabetes.” This editorial is a commentary on this paper, intending to highlight, one more time, the importance of a positive family history (FH+) of type 2 diabetes (T2D) for estimating diabetes occurrence in the adult population as well as the importance of physical activity (PA) for maintaining optimal body composition and a low incidence rate of chronic disease.2 Since 2011, my research group has provided periodical pieces of evidence (2011, 2013, and 2014) about the influence of FH+ on the basal metabolic rate of women,3 on body composition and fasting glucose levels of healthy people,2 on body composition and basal glycemia in sedentary people,4 and on anaerobic performance of young male elite athletes.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Acute effects of different administration order of stretching exercises: effects on range of motion and cross-over effect

    BACKGROUND: The aim of this manuscript is to investigate if stretching exercise administration order may influence outcomes pertinent to range of movement (roM). METHODS: A total sample of 108 participants was randomized into five groups. Eight sets of unilateral static stretching (SS) of 30s duration each with a 30s rest were administered to the right leg. One group underwent SS of the knee extensors (KE), another to the knee flexors (KF), another first to the KE and then to the KF, another first to the KF and then to the KE while the last group was used as control (CG). Each group was assessed for roM of both lower limbs for either the Ke and Kf motion (passive hip extention [phe] and passive straight leg raise [pSlr], respectively). Measures were assessed before (T0), immediately after (T1), and 15 minutes after the intervention (T2). reSulTS: No differences were observed for time (T0 vs. T1 vs. T2) for all measures in the cG for both limbs. Time-x-group interactions were observed only in the intervention limb (P<0.0007 and 0.004, ES 0.73 and 0.55, for KE and KF, respectively). Within the intervention limb, a significant increase in the PHE was observed from T0 to T1 only in the KE and KF/KE groups. For measures of the PSLR, a significant increase was observed from T0 to T1 only in the KF and KE/KF groups. No differences neither for time or group were observed in the control limb. CONCLUSIONS: Our results highlight that exercise administration order has an effect on ROM outcomes. Measures of ROM significantly increase only for the last stretched muscle in each intervention group. No crossover effect was observed in the contralateral limb.

    Sport, Health Economics and Society (SHES) Series- Vol. 1: Essays in Sport Research

    No full text
    Sport is a global phenomenon that encompasses contemporary societies. Sport issues have attracted the interdisciplinary interest of various disciplines, from medicine and quality of life research to economics, sociology and law. Based on such an assumption, which places sports science within the realm of social sciences, the Sport, Health Economics and Society series (SHES) aims to understand and address issues and potential developments in contemporary sports practise and experience. This first edition of the SHES series makes connections between different disciplines and topics, from economics to management and sociology, to highlight key issues of sport experience and suggest potential avenues for the specific development of the field
