BACKGROUND Hamstring strain is a common injury in sprinters and jumpers, and therefore time to return to sport and secondary prevention become of particular concern. OBJECTIVE To compare the effectiveness of two rehabilitation protocols after acute hamstring injury in Swedish elite sprinters and jumpers by evaluating time needed to return to full participation in the training process. STUDY...

The present study aimed to determine whether distinct sets of tendon properties are seen in athletes engaged in sports with contrasting requirements for tendon function and structural integrity. Patellar and Achilles tendon morphology and force-deformation relation were measured by combining ultrasonography, electromyography and dynamometry in elite ski jumpers, distance runners, water polo pla...

Background: The ACSL A/G single nucleotide polymorphism is associated with endurance trainability. It was previously demonstrated that AA carriers had a reduced maximal oxygen consumption (VO2 max) in response to training compared GG carriers, and this explained 6.1% of the variance VO2 max training. aim present study determine prevalence among soccer players. Methods: One hundred sixty-seven m...

This study uses inertial sensors to measure ski jumper kinematics and joint dynamics, which was until now only a part of simulation studies. For subsequent calculation of dynamics in the joints, a link-segment model was developed. The model relies on the recursive Newton-Euler inverse dynamics. This approach allowed the calculation of the ground reaction force at take-off. For the model validat...

The main purpose of this study was to examine whether the use of internal imagery would affect high jumping performance for active high jumping athletes. Over a period of six weeks, a group of active high jumpers were trained with an internal imagery program for a total of 72 minutes. This group was compared to a control group consisting of active high jumpers that only maintained their regular...

The purpose of the present investigation was to compare Aerobic Capacity and Anaerobic Capacity of female Players of Track and Field events (Sprinters, Jumpers and Throwers). To achieve the set objective, one hundred and twenty (120) Players (Sprinters =40, Jumpers =40 and Throwers =40) of individual games were selected from Department of physical education Punjab University Chandigarh, Departm...

In high jumping, the horizontal velocity which jumpers aim to reach by end of run-up must be maximum that they can control, enabling them clear greatest height possible. Furtherm...

This study investigates the frequency of injuries, in particular dental injuries, among ski jumpers and Nordic combined athletes. It also examines the level of knowledge regarding tooth protection and tooth rescue boxes in this population. Of the 465 sportswomen and sportsmen who took part in the study, 230 (62.5%) of the 368 ski jumpers and 56 (56.5%) of the 97 Nordic combined athletes had sus...

The effect of the Jasper Jumper in the treatment of Class II, division 1 malocclusions was studied in 26 consecutive 13-25-year-old patients. The median treatment time was 5 months, followed by a median period of observation or retention of 7 months. The effects of the treatment were evaluated from cephalograms taken before the treatment, at the removal of the Jumpers and at the end of the peri...
