Hematological changes following an Ironman triathlon: An antidoping perspective.

Understanding and characterizing confounding factors to the Athlete Biological Passport (ABP) is crucial for the reliable interpretation of biological profiles in the antidoping field. The physiological effects on hematological parameters and plasma volume (PV) following competition in a long-distance triathlon, as seen in the Ironman discipline, have yet to be fully described and are the focus of this study. Complete blood count blood tests were conducted on 19 Ironman triathletes before and after an Ironman triathlon to characterize changes in hematological parameters and the effect on ABP interpretation, as it was hypothesized that changes in the plasma volume may result in the presentation of atypical ABP profiles.

Hypothalamic-Pituitary-Testicular Axis Effects and Urinary Detection Following Clomiphene Administration in Males.

Context: Clomiphene is a performance-enhancing drug commonly abused by males in sport, but the extent to which testosterone increases in healthy males following its use is unknown. In addition, evidence suggests that clomiphene, a mixture of cis- and trans-isomers zuclomiphene and enclomiphene, is detectable in urine for months following use; the isomer-specific urinary detection window has yet to be characterized in a controlled study.

Objective: To determine the effect of once-daily, 30-day clomiphene treatment on serum testosterone and gonadotropin levels in the subject population studied and the urinary clearance and detection window of clomiphene isomers following administration for antidoping purposes.

Boxing fatalities in relation to rule changes in Japan: secondary data analysis.

Objectives: To examine whether changing weigh-in from the same day of the match to the day before the match and prohibiting 6-oz gloves are associated with fatalities in boxing matches sanctioned by the Japan Boxing Commission (JBC).

Methods: We analyzed the rates of boxing fatalities before and after the two rule changes above via secondary analysis of data. Demographics and boxing records of deceased boxers were examined using descriptive statistics, exact binomial test the Mann-Whitney-Wilcoxon test and Fisher's exact tests.

Game Schedules and Rate of Concussions in the National Football League.

Background: Concussion prevention in the National Football League (NFL) is an important priority for player safety. The NFL now has modified game schedules, and one concern is that unconventional game schedules, such as a shortened rest period due to playing on a Thursday rather than during the weekend, may lead to an increased risk of injuries.

Hypothesis: Unconventional game schedules in the NFL are associated with an increased rate of concussion.
