Hops, steps and jumps

Christopher Surridge
1995 Nature  
In two papers on pages 748 and 751 of this issue, Milligan, Sweeney and colleagues take one of the major steps in this quest.  ...  The power house of contraction is the protein myosin (red and blue in the figure) which acts against the filamentous protein actin (white in figure) .  ...  The authors then went a step further.  ...

Potential for Non-Contact ACL Injury Between Step-Close-Jump and Hop-Jump Tasks

Li-I Wang, Chin-Yi Gu, Wei-Ling Chen, Mu-San Chang
2010 Journal of Sports Science and Medicine  
Eleven elite male volleyball players were recruited to perform hop-jump and step-close-jump tasks.  ...  This study aimed to compare the kinematics and kinetics during the landing of hop-jump and step-close-jump movements in order to provide further inferring that the potential risk of ACL injuries.  ...  The landing maneuvers of the step-close-jump and hop-jump were notably different.  ...

Respiratory complex I: hop (structure), step (reaction mechanism) and jump (potential remedy)

Takao Yagi, Akemi Matsuno-Yagi
2014 Journal of Bioenergetics and Biomembranes  
There were many valuable biochemical and biophysical discoveries. Then came a take-off. The hop phase was a great forward motion with elucidation of the three-dimensional structure.  ...  As the take-off leg lands in the step phase, a number of proposals for the mechanism started bursting.  ...

Biomechanical Evaluation of the Phases of the Triple Jump Take-Off in a Top Female Athlete

Abeer Eissa
2014 Journal of Human Kinetics  
The maximum pushing time was in the jump phase (0.10 s), while the pushing time was equal in the hop and step phases (0.05 s).  ...  This jump is comprised of 3 take-off phases (hop, step, and jump), each playing an important role, as they require the jumper to tolerate extremely high forces of impact and to maintain a high level of  ...  Table 3 shows a continual decrease in horizontal velocity from the hop to the step to the jump and a continual increase in vertical velocity from the hop to the step to the jump.  ...
