Swimming is one of the most popular sports worldwide. Competitive swimming is one of the most watched sports during the Olympic Games. Swimming has unique medical challenges as a result of a variety of environmental and chemical exposures. Musculoskeletal overuse injuries, overtraining, respiratory problems, and dermatologic conditions are among the most common problems swimmers encounter. Although not unique to swimming, overtraining is a serious condition which can have significant negative impact on swimmers' health and performance...

BACKGROUND: Anemia has been implicated in adverse health outcomes of athletes and military trainees, ranging from overuse injuries to degraded physical and cognitive performance. The purpose of this study was to investigate prevalence of anemia among US Air Force (USAF) basic trainees, to compare physical performance and discharge rates between anemic and non-anemic trainees, and to determine the risks and relative risks of being discharged for anemic versus non-anemic women and men. METHODS: All USAF basic trainees were screened for anemia between July 2013 and January 2014, during an 8-week basic training course at Joint Base San Antonio-Lackland, TX...

With increasing participation and intensity of training in youth sports in the United States, the incidence of sports-related injuries is increasing, and the types of injuries are shifting. In this article, the authors review sports injuries of the lower extremity, including both acute and overuse injuries, that are common in or specific to the pediatric population. Common traumatic injuries that occur in individuals of all ages (eg, tears of the acetabular labrum and anterior cruciate ligament) are not addressed, although these occur routinely in pediatric sports...

The aim of this study was to determine the effect of aging on power generation and joint coordination during a leg press, in order to increase understanding of how functional movements are affected during the aging process. 44 older and 24 younger adults performed eight sub-maximal power repetitions on a seated leg press dynamometer. Peak power and velocity (at 40% maximum resistance) were measured along with the coordination (coupling angle) of the lower limb joints using the vector coding technique. The younger adults produced significantly greater peak power than the older adults (mean ± SD; 762 W ± 245 vs 361 W ± 162, p < 0...

Tibial stress fractures are among the most common and potentially serious overuse injuries in runners. The fractures are thought to be related in part, to excessive loading variables, such as vertical average loading rate (VALR) and vertical instantaneous loading rate (VILR). Although there are several methods for calculating loading rate in running, little is known about the differences between the results produced by these methods. The purpose of this study was to compare 3 previously published methods of calculating VALR and VILR during running...

A cross-sectional design was employed retrospectively to evaluate injuries self-reported by 71 pre-professional ballet dancers over one season. Some of the descriptive findings of this survey were consistent with those of previous research and suggest particular demographic and injury trends in pre-professional ballet. These results include gender distribution, mean age and age range of participants, training hours, injury location, acute versus overuse injuries, as well as average number of physiotherapy treatments per dancer...

INTRODUCTION AND OBJECTIVES: Healthy feet are important for overall health and well-being. Previous studies of older subjects showed that those with a lowered arch had an increased odds of having foot deformities, pain, and hyperpronation in gait. (1-3) No investigation to date has comprehensively characterized foot biomechanics in a large sample of healthy active young subjects. METHODS: Foot structure, function, and arch height flexibility (AHF) were measured in 1,052 incoming cadets to the United States Military Academy...

Shoulder injuries in pediatric athletes are typically caused by acute or overuse injuries. The developing structures of the shoulder lead to injury patterns that are distinct from those of adult athletes. Overuse injuries often affect the physeal structures of the proximal humerus and can lead to pain and loss of sports participation. Shoulder instability is common in pediatric athletes, and recurrence is also a concern in this population. Fractures of the proximal humerus and clavicle are typically treated with conservative management, but there is a trend toward surgical intervention...

Pediatric overuse injuries are becoming more prevalent in today's society with more children competitively playing year-round sports at a younger age. The importance of prompt diagnosis and treatment is paramount to the treatment for these injuries, second only to rest and activity modification. This article will focus on overuse injuries of the upper extremity, specifically: little league elbow, elbow osteochondritis dissecans, and gymnast wrist. It will also discuss the pathophysiology, diagnosis, imaging, and treatment of each of these entities...

The windmill softball pitch generates considerable forces about the athlete's shoulder and elbow. The injury pattern of softball pitchers seems to be primarily overuse injury, and they seem not to suffer the same volume of injury that baseball pitchers do. This article will explore softball pitching techniques, kinetics and kinematics of the windmill pitch, epidemiology of softball pitchers, and discuss possible etiologies of softball pitching injuries.

Sports specialization is becoming the norm in youth sports for a variety of reasons. When sports specialization occurs too early, detrimental effects may occur, both physically and psychologically. If the timing is correct and sports specialization is performed under the correct conditions, the athlete may be successful in reaching specific goals. Young athletes who train intensively, whether specialized or not, can also be at risk of adverse effects on the mind and body. The purpose of this clinical report is to assist pediatricians in counseling their young athlete patients and their parents regarding sports specialization and intensive training...

INTRODUCTION: Overuse pain syndromes constitute a troublesome byproduct of military infantry training, particularly in female fighters. These injuries result in lost days of training, pain and discomfort and can affect fitness and fighting abilities. We hypothesized that a gender specific vest would reduce the incidence of overuse pain syndromes in a population of female recruits during basic training. OBJECTIVE: The purpose of this study was therefore to examine the effect of a novel gender-specific combat vest on the incidence of lower back pain (LBP), anterior knee pain syndrome (AKPS), and plantar heel foot pain (PHFP) among female recruits...

Rock climbing is becoming an increasingly popular sport in Israel with more and more climbing walls being built in the cities and new routes being traced on cliffs around the country. Our account describes the case of a 15 years old climber with chronic pain (without trauma) in the 3rd finger of the right hand. A stress fracture, involving the proximal interphalangeal joint (SH3) of the middle phalanx, was diagnosed. The fracture healed following two months of rest with gradual return to activity. As this sport becomes more common, there is an increasing need for knowledge about the characteristic injuries, their diagnosis and treatment...

Acute and overuse tendon disorders are frequently observed in the middle-aged active population. Tendon overuse injuries are currently designated as "tendinopathy". Histopathological studies have shown that chronic tendinopathy is frequently characterised by degenerative changes, such as decreased organisation of collagen, altered cell distribution and neovascularisation. In the recent years, scientific research and technology in the field of regenerative medicine has provided a new perspectives on managing chronic tendinopathy...

More children are participating in organized and recreational athletics at a younger age. It has been well documented that increased athletic specialization and year-round activities have resulted in higher incidences of overuse injuries, including stress fractures and stress reactions. Initially, stress fractures can be radiographically occult. Continued stress on the injured bone or cartilage can lead to progressive radiographic changes. Because of the prevalence of these injuries, both orthopedic surgeons and radiologists should be aware of the radiographic and magnetic resonance imaging (MRI) features of common stress fractures in children...

Pitching is not without risk of overuse injuries. Pitch counts have been instituted to reduce the risk, but Riff et al.'s article clearly demonstrates that as pitchers get older they do not adhere to these counts, which increases the risk of injury.

The study objective was to determine whether spatiotemporal gait parameters could predict lower-limb overuse injuries in cohort of combat soldiers during first year of military service. Newly recruited infantry soldiers walked on a treadmill at a 15° incline with a fixed speed of 1.67 m/sec while wearing a standard military vest with a 10 kg load. Stride time variability, stride length variability, step length asymmetry, and the duration of the loading response phase of the gait cycle were measured. Injury data on 76 soldiers who did not report musculoskeletal complaints at initial screening were collected one year after recruitment...

Benefits of physical activity during adolescence have widely been demonstrated. Yet, raising awareness among young athletes and their surrounding about risks associated with too early specialization or energy deficit--with or without eating disorder--is of outmost importance. Such behaviours can affect adolescents' physical or psychological development as well as compromise their athletic career not to mention the potential negative impact on their athletic performance. Primary care practitioners play an important role in early detection and prevention of overuse injuries as well as psychological distress associated with intense physical activity...

In brief: A questionnaire was used to examine the number, nature, and etiology of injuries to Canadian nationally ranked figure skaters over a one-year period and to measure the consequent loss of training time. Of the 60 respondents, 28 (46.6%) reported having had a significant injury during the year. Fifty percent of the injuries were acute and 43% were overuse injuries. The respondents spent an average of 27.2 hours a week on the ice, but only 11.9 minutes (0.2 hour) per week in stretching and warm-up exercises...
