A Comparison of the Habitual Landing Strategies from Differing Drop Heights of Parkour Practitioners (Traceurs) and Recreationally Trained Individuals
Kinetics forefoot Parkour dissipation kinematics
2016/2/23
Parkour is an activity that encompasses methods of jumping, climbing and vaulting. With landing being a pertinent part of this practise, Parkour participants (traceurs) have devised their own habitual...
Landing Techniques in Beach Volleyball
Video analysis gender differences volleyball injuries overuse condition
2015/5/18
The aims of the present study were to establish a detailed and representative record of landing techniques (two-, left-, and right-footed landings) in professional beach volleyball and compare the dat...
Ground Reaction Forces and Loading Rates Associated with Parkour and Traditional Drop Landing Techniques
Kinetics absorption forefoot roll
2015/5/14
Due to the relative infancy of Parkour there is currently a lack of empirical evidence on which to base specific technique instruction upon. The purpose of this study was to compare the ground reactio...
Muscle activity response to external moment during single-leg drop landing in young basketball players: The importance of biceps femoris in reducing internal rotation of knee during landing
ACL injury risk factors knee moment muscle activation.
2015/5/11
Internal tibial rotation with the knee close to full extension
combined with valgus collapse during drop landing generally
results in non-contact anterior cruciate ligament (ACL) injury.
