The aim of this study was to examine the match physical demands and exercise intensity associated with men rugby union refereeing using global positioning system technology. Ten male rugby union referees (age, 37.1 ± 5.9 years; body mass, 83.7 ± 4.8 kg; height, 175.5 ± 6.2 cm) were analyzed 2-4 times during a total of 30 national level matches. The average total distance covered by the referees...

The aim of this study is to investigate the differences in lower limb kinematics and kinetics between experienced (EW) and inexperienced (IEW) moderate high-heel wearers during jogging and running. Eleven experienced female wearers of moderate high-heel shoes and eleven matched controls participated in jogging and running tests. A Vicon motion analysis system was used to capture kinematic data ...

BACKGROUND Among the many factors that determine the outcome following anterior cruciate ligament (ACL) reconstruction, the position of the femoral tunnel is known to be critically important and is still the subject of extensive research. OBJECTIVE We aimed to retrospectively compare the outcomes of arthroscopic ACL reconstruction using transtibial (TT) or anteromedial (AMP) drilling techniqu...

A young woman comes to your chiropractic practice with a complaint of anterior knee pain. As spring weather returns, patient activity levels often increase. A sedentary lifestyle through the winter months may now be replaced with jogging, biking, hiking, or other outdoor activities. Anterior knee pain can result from this sudden increase in activity levels. This may affect 1 in 4 active individ...

Spontaneous peri-renal hemorrhage (SPH) was first described in 1856 by Carl Wünderlich, a German physician, who identified a non-traumatic renal hemorrhage confined to the subcapsular and peri-renal space [1]. Most of the time, the clinical symptoms of SPH are nonspecific (flank pain and/or abdominal mass), necessitating imaging studies. The overall sensitivity of CT scans in detection of SPH c...

BACKGROUND Regular physical exercise may improve a variety of physiological and psychological factors in depressive persons. However, there is little experimental evidence to support this assumption for adolescent populations. We conducted a randomized controlled trial to investigate the effect of physical exercise on depressive state, the excretions of stress hormones and physiological fitness...

This study investigated the positional movement patterns in elite junior Australian Football (AF). Thirty players (17.1 ± 0.9 years) participating in this study were tracked over seven home games of the regular 2006 Victorian junior (Under 18) league season. Using lapsed-time video analysis, each position for an entire match was videotaped on three separate occasions over the course of the seas...

OBJECTIVE To determine the effect of stretching and jogging on the series elastic muscle stiffness of the plantar flexors and on the range of dorsiflexion at the ankle joint. METHODS 24 healthy subjects participated in this study. Each subject undertook all of the following protocols, in random order: (1) stretching protocol: five 30 s static stretches with 30 s rest between stretches; (2) ae...

Medial tibial stress syndrome (MTSS) is one of the most common exercise-induced leg pain. The navicular drop (ND) was identified as a risk factor for MTSS. This study aimed to evaluate the short-term effects of sports taping applied to the supporting lower leg during sitting, standing, walking, and jogging to restrict the ND in healthy elite athletes.Twenty-four healthy elite athletes without a...
