Training, Injury, and Lifestyle Characteristics of Recreational Triathletes

Triathlon is a popular sport among recreational and competitive athletes. As triathletes compete in races ranging from 16 to 140.6 miles and train in three disciplines simultaneously, it is difficult to identify injury risk factors. The aim of this study was to evaluate characteristics of a group of recreational triathletes regarding their medical history, training regimen, and injuries. Thirty-four triathletes completed this survey. We found a wide range of body types, training habits, and lifestyle characteristics. As in previous studies, we found a high rate of injuries in our surveyed triathletes. Injury rates were higher in athletes who had completed a longer race and those who reported higher training times per week. Additionally, many individuals have medical problems, use a variety of supplements, and follow specific dietary restrictions, which need to be considered in addition to training when assessing injury risk and recovery from injury

ADHD Prescription Medications and Their Effect on Athletic Performance: A Systematic Review and Meta-analysis

Background Stimulant medications used for the treatment of Attention Deficit-Hyperactivity Disorder (ADHD) are believed to provide a physical advantage in athletics, but several of these medications are not regulated by the World Anti-Doping Association. Given the prevalence of ADHD among the athlete population and concern for abuse of ADHD medications, this review and meta-analysis aimed to evaluate effects of ADHD medications on athletic performance, thereby appraising the validity of claims of performance enhancement. Methods A search of MEDLINE, Embase, CINAHL, and Cochrane Review databases was performed for all randomized controlled trials evaluating athletic performance after ingestion of placebo or ADHD treatment medications from August 2020 through November 2020. All RCTs identified from these search criteria were included for screening, with exclusion of any animal studies. Two reviewers (JB, CK) assessed methodological quality and risk of bias using CONSORT 2010 and Cochrane Collaboration tools. Study results were compiled with corresponding p values for each finding. Effect sizes (Cohen's D) for athletic performance and physiological changes were aggregated for each study. Studies were further screened for homogeneity that would allow for meta-analysis. Heterogeneity was calculated using I2. Results A total of 13,033 abstracts evaluating amphetamine, methamphetamine, methylphenidate, and bupropion were screened. The final analysis included nine studies, six of which found significant improvement in athletic performance with use of stimulant medications (p < 0.05). Methylphenidate and amphetamine were consistently identified to have a performance effect. Secondary effects identified included significant increase in heart rate, core temperature, and elevation of various serum hormone levels (p < 0.05). Effect size evaluation found seven studies demonstrating small to large effects on physical performance, as well as in categories of cardiometabolic, temperature, hormone, and ratings of perceived exertion, to varying degrees. A meta-analysis was performed on two studies, demonstrating conflicting results. Conclusions Dopaminergic/noradrenergic agonist medications appear to have a positive effect on athletic performance, as well as effects on physiological parameters. Further consideration of medications currently not regulated, i.e. bupropion, is warranted given evidence of athletic performance enhancement.

Pelvic Floor Dysfunction in the Female Athlete

Pelvic floor dysfunction (PFD) is a term used to describe a variety of disorders involving moderate to severe impairment of the pelvic floor muscles. It can be divided into two broad categories. Relaxing PFD is more common, presenting with urinary incontinence, fecal incontinence, or pelvic organ prolapse. Nonrelaxing PFD symptoms include impaired ability to evacuate urine or stool, sexual dysfunction, and pelvic pain. Unfamiliarity with this diagnosis among medical providers along with nonspecific symptoms often lead to a delayed or missed diagnosis for patients. Here, we present the case of a collegiate soccer player with PFD to illustrate the severity of presentation and progression of this disorder. We review the current literature regarding nonrelaxing PFD and all types of PFD in female athletes to raise awareness and recognition of this condition

Triathlon Injuries: Transitioning from Prevalence to Prediction and Prevention

The Ironman triathlon began in Hawaii in 1978 with 50 participants. Since then, the race has continued to grow in popularity. Injuries are very common among triathletes. Studies have looked at the relationship between injuries and many different factors. Sex, age, and morphological characteristics, such as height, weight, and body mass index, have not been shown to correlate with injury. The association between training volume and injury has shown inconsistent results. This could be due to multiple factors in study design including definitions and evaluation of training volume. Recent literature highlights the complex relationship between risk factors and injury occurrence. This article reviews the epidemiology and risk factors for musculoskeletal injuries in Ironman distance triathletes as well as general research and theories on training volume assessment and injury risk to provide recommendations for future studies and strategies for injury prevention
