Two patients-one with a terrible triad fracture dislocation and one with an anterior olecranon fracture dislocation—weretreated for maltracking of the elbow (medial subluxation). The radial head articulated with the lateral trochlea while theulnar trochlear notch was perched over the medial trochlea. The late revision surgery could not correct the subluxationbecause the joints were accustomed t...

Suppose k + 1 runners having nonzero constant speeds run laps on a unit-length circular track starting at the same time and place. A runner is said to be lonely if she is at distance at least 1/(k + 1) along the track to every other runner. The lonely runner conjecture states that every runner gets lonely. The conjecture has been proved up to six runners (k ≤ 5). A formulation of the problem is...

conclusions the results suggested that severely thin girl runners has steadily increased. surveys on the health consequences of extreme thinness are necessary for the female adolescent runners. methods body mass index (bmi) were analysed in 9,881 female and 12,786 male runners participating in the annual national road relay races between 1989 and 2014 using the directory of a track and field ma...

Selected short distance runners, middle distance runners and long distance runners were subjected to graded exercise on a treadmill. The maximum aerobic power (VO2 max) and other indices related to oxygen transport system viz. heart rate, ventilation volume, breathing reserve, dyspnoeic index, O2 pulse and RQ were recorded at respective VO2 max work loads, and the values were compared. Long dis...

Running research has focused on reducing injuries by changing running technique. One proposed method is to change from rearfoot striking (RFS) to forefoot striking (FFS) because FFS is thought to be a more natural running pattern that may reduce loading and injury risk. Muscle activity affects loading and influences running patterns; however, the differences in muscle activity between natural F...

OBJECTIVE The aim of this study was to investigate the kinetics, kinematics and muscle activity in runners with Achilles tendinopathy. DESIGN Case-control study. SETTING Biomechanics laboratory. PARTICIPANTS 21 runners free from injury and 21 runners with Achilles tendinopathy performed 10 running trials with standardised running shoes. Injured runners were diagnosed clinically according ...

BACKGROUND Healthy elite runners often report bronchial symptoms when training in subzero temperatures. The occurrence and causes of exercise-induced bronchospasm after heavy exercise in cold air were investigated in elite runners. METHODS Thirty two non-asthmatic runners, mostly from Finnish national teams, volunteered to take part in the study. They answered a questionnaire and were subject...

PURPOSE The purpose of this study was to evaluate the incidence of chronic knee changes in long-distance runners based on the training status, including distance, running frequency, training pace, and running experience. METHODS MRI of the knee was performed in 26 non-professional runners 5 days after their last training unit. Lesions of the menisci and cartilage (5-point scale), bone marrow ...
