INTRODUCTION AND HYPOTHESIS: People are increasingly aware of healthy lifestyles. Extenuating practice can injure the pelvic floor. Urinary incontinence (UI) is a prevalent condition in women whether they exercise professionally or not. The most common symptom is stress UI. It is reported in a large variety of sports and may interfere with everyday life or training, leading athletes to change or compromise their performance or risk compromising it. We aimed to assess the prevalence of UI in female athletes and to determine whether the type of sport might also influence UI...

Background: Female patients are more likely to suffer a second anterior cruciate ligament (ACL) injury after ACL reconstruction (ACLR) and return to sport (RTS) compared with healthy female controls. Few studies have examined the energy absorption contribution (EAC) that could lead to this subsequent injury. Hypothesis: The ACLR group would demonstrate an altered EAC between joints (hip, knee, and ankle) but no difference in quadriceps, hip abduction, or hip external rotation (ER) strength at the time of RTS...

BACKGROUND: A collection of studies have demonstrated that approximately one-third of female nulliparous athletes experience urinary incontinence during their athletic activities. Contributing factors of incontinence that have thus far been the focus of study include type of sport, duration and intensity of athletic activity, use of hormonal contraception, and weight. There has, as yet, been a notable underemphasis on several other factors which influence incontinence, including bowel pattern, urinary habits, and menstrual status...

BACKGROUND: Surgery for athletic pubalgia usually consists in abdominal wall repair combined with routine bilateral adductor tenotomy. We currently confine the surgical procedure to the injured structure(s) (abdominal wall only, adductor tendon only, or both) to limit morbidity and expedite recovery. Outcomes of this à la carte approach are unclear. The objectives of this retrospective study were to determine the return to play (RTP) time, evaluate the potential influence of injury location, and assess the frequency of recurrence or contralateral involvement...

Synopsis Our understanding of femoroacetabular impingement (FAI) syndrome is slowly improving. The number of studies on all aspects (aetiology, prevalence, pathophysiology, natural history, treatment, and preventative measures) of FAI syndrome has grown exponentially over the past few years. This commentary provides the latest updates on the prevalence of cam and pincer hip morphology and its relationship with development of hip osteoarthritis (OA). Cam and pincer morphology is highly prevalent in the general population and in this paper is presented for different subgroups based on: age, sex, ethnicity, and athletic activity...

This study aimed to estimate the optimal body size, limb segment length, and girth or breadth ratios of 100-m breaststroke performance in youth swimmers. In total, 59 swimmers [male: n = 39, age = 11.5 (1.3) y; female: n = 20, age = 12.0 (1.0) y] participated in this study. To identify size/shape characteristics associated with 100-m breaststroke swimming performance, we computed a multiplicative allometric log-linear regression model, which was refined using backward elimination. Results showed that the 100-m breaststroke performance revealed a significant negative association with fat mass and a significant positive association with the segment length ratio (arm ratio = hand length/forearm length) and limb girth ratio (girth ratio = forearm girth/wrist girth)...
