Many field sports involve equipment that restricts one or both arms from moving while running. Arm swing during running has been examined from a biomechanical and physiologic perspective but not from an injury perspective. Moreover, only bilateral arm swing suppression has been studied with respect to running. The purpose of this study was to determine the influence of running with one arm restrained on lower extremity mechanics associated with running or sport-related injury. Fifteen healthy participants ran at a self-selected speed with typical arm swing, with one arm restrained and with both arms restrained...

[Purpose] Competitive sport places strict demands on the cardiovascular systems of veteran trail runners. Our research objective was to evaluate the dynamics of microcirculation parameters of veteran runners in hypoxic and mid-altitude conditions. [Subjects and Methods] Seven male runners from Russia and Italy between the ages of 50 and 60 years were examined whilst competing at mid-altitude (1,500-2,000 m above sea level). The same runners were examined in a simulated mid-altitude hypoxic environment, which was a hypoxic chamber with 16% oxygen concentration, for 720 minutes...

Previous research has reported a prevalence of running related injuries in 25.9% to 72% of all runners. A greater hip internal rotation and adduction during the stance phase in running has been associated with many running related injuries, such as patellofemoral pain. Researchers in the USA designed a treatment device 'the Powers™ strap' to facilitate an external rotation of the femur and to thereby control abnormal hip and knee motion during leisure and sport activities. However, to date no literature exists to demonstrate whether the Powers™ strap is able to reduce hip internal rotation during running...

This is a first look at a non-targeted screening method based on Orbitrap GC/MS technology for a large number of banned compounds in sports found in urine, including: exogenous anabolic steroids, β-agonists, narcotics, stimulants, hormone modulators, and diuretics. A simple sample preparation was processed in four steps: an enzymatic hydrolysis, liquid-liquid extraction, evaporation and trimethylsilylation. All compounds were able to meet WADA's sensitivity criteria with mass accuracies less than 1 ppm and with sufficient points across the peak by running the Orbitrap GC/MS in full scan mode...

Objective Carotid intima-media thickness (IMT) is used to assess cardiovascular risk and progression of atherosclerosis. It is known that regular physical activity of moderate intensity has beneficial effects on the vasculature. However, it is still discussed controversially whether prolonged exercise, including participation in exhaustive competitive sports such as long-distance races, has also beneficial effects or might even be harmful regarding the cardiovascular system. Patients and methods Thirty-eight male marathon runners (45...

Exercise, like running, is good for overall health and, specifically, our hearts, lungs, muscles, bones, and brains. However, some people are concerned about the impact of running on longterm joint health. Does running lead to higher rates of arthritis in knees and hips? While many researchers find that running protects bone health, others are concerned that this exercise poses a high risk for age-related changes to hips and knees. A study published in the June 2017 issue of JOSPT suggests that the difference in these outcomes depends on the frequency and intensity of running...

BACKGROUND: Returning to high-impact sport is an increasingly frequent functional demand following hip replacement. The literature, however, is sparse on the subject and nonexistent regarding triathlon. We therefore conducted a retrospective study of hip resurfacing in triathlon players, to determine: (1) whether it is possible to return to this kind of sport; (2) if so, whether it is possible to return to the same level; and (3) how a resurfaced hip behaves under these conditions. HYPOTHESIS: Hip resurfacing allows return to competition level in long-distance triathlon...

Athletic children are prone to overuse injuries, especially at the heel and knee. Since footwear is an extrinsic factor of lower limb injury risk, the aim of this study was to assess the influence of shoe aging on children running biomechanics. Fourteen children active in sports participated in a laboratory biomechanical evaluation. A new pair of shoes was provided to each participant at an inclusion visit. Four months later, the participants performed a running task and their kinematics and kinetics were assessed both with their used shoes and with a new pair of shoes identical to the first...

The critical speed (CS) concept helps characterize the aerobic and anaerobic fitness of an athlete. Rugby players should hypothetically have modest CS values but extremely high curvature constant (D') values, yet, normative data are currently unavailable. To develop normative data of CS and D' for high-level male rugby players, a total of 30 male rugby players, were recruited from the Eastern Cape of South Africa. All subjects performed the running 3-min all-out exercise test (3 MT) using global positioning system (GPS) technology to determine CS and D'...
