ISSN exercise & sport nutrition review: research & recommendations

Sports nutrition is a constantly evolving field with hundreds of research papers published annually. For this reason, keeping up to date with the literature is often difficult. This paper is a five year update of the sports nutrition review article published as the lead paper to launch the JISSN in 2004 and presents a well-referenced overview of the current state of the science related to how to optimize training and athletic performance through nutrition. More specifically, this paper provides an overview of: 1.) The definitional category of ergogenic aids and dietary supplements; 2.) How dietary supplements are legally regulated; 3.) How to evaluate the scientific merit of nutritional supplements; 4.) General nutritional strategies to optimize performance and enhance recovery; and, 5.) An overview of our current understanding of the ergogenic value of nutrition and dietary supplementation in regards to weight gain, weight loss, and performance enhancement. Our hope is that ISSN members and individuals interested in sports nutrition find this review useful in their daily practice and consultation with their clients

Hemostatic response to acute physical exercise in healthy adolescents

The chronic and immediate post-exercise responses in the hemostatic and fibrinolytic systems have been shown to be variable and reflect differing adaptations with ageing and responses to exercise protocols. This study investigated the effects of acute and exhaustive exercise on the amplitude and duration of hemostatic and fibrinotytic responses in young adolescent mates. The sample comprised 10 sedentary boys (13.2 +/- 0.5 years, 55.8 +/- 11.3kg, 165.7 +/- 7.4cm), who had not exercised or received any medication for at least 2 weeks before the experiments. The subjects performed exhaustive stepping exercise, consisting of 1 s up and down cycles to fatigue. When the subjects were unable to maintain the required stepping rhythm, they were given a 30s recovery period. Following each 30s recovery participants recommenced the stepping cadence until fatigue prevented them continuing. Venous blood samples were drawn before and immediately, 1 and 24h after exercise to assess the following coagulation and fibrinolytic parameters: Platelet counts, activated partial thromboptastin time (aPTT), prothrombin time (PT), coagulation factor VIII (FVIII:C), von Willebrand factor (vWF), fibrinogen concentration, thrombin-antithrombin complex (TAT), D-dimer, plasminogen activator inhibitor (PAI-1), and tissue-type plasminogen activator (t-PA). Immediately following exercise, platelet counts, aPTT, FVIII, vWF and t-PA were significantly elevated in contrast to PAI-1, which decreased significantly until 1 h after exercise. FVIII and platelet counts were elevated at 1 and 24h after exercise, respectively. Only the parameters FVIII and PAI-1 did not return to baseline values during the first hour after physical exercise. When compared to adults the results revealed different rates and ranges of coagulation and fibrinolysis parameters being activated by exhaustive exercise in this group of adolescents

Law and LGBQ-Parent Families

This paper addresses how the law affects LGBQ-parent families. We first outline the legal landscape that LGBQ parents face in the US, underscoring that it varies drastically by state and creates inequity for families. Reviewing existing social science research, we then address how the law affects three processes for LGBQ people: desiring parenthood, becoming a parent, and experiencing parent- hood. Our review indicates that the law affects if and how LGBQ people become parents. LGBQ people consider the law as they make decisions about whether to pursue adoption, donor insemination, or surrogacy and often view the latter two pathways as the most legally secure. Further, the law continues to be salient for LGBQ parents throughout parenthood and affects family well-being. Specifically, legal inequity diminishes parent’s well-being, the relationship among couples who are parenting, and parents’ ability to effectively advocate for their children in institutional settings like healthcare contexts. Finally, we address directions for future research for scholars interested in the law, family processes and outcomes, and LGBQ families
