Is the effect of a countermovement on jump height due to active state development?

Article Abstract:

A study was conducted to determine whether the difference in jump height between countermovement jumps (CMJ) and squat jumps (SJ) could be caused by the difference in the active state during propulsion. The results indicate that a greater height in CMJ as compared to that in SJ is observed, which could be attributed to the fact that in CMJ active state is developed during the preparatory countermovement whereas in SJ it is developed during the propulsion phase.

Aerodynamic characteristics as determinants of the drafting effect in cycling

Article Abstract:

An investigation was conducted to quantify the individual aerodynamic and anthropometric characteristics of drafting effect in cycling. It was found that during paired cycling the drafting effect increases in proportion to the drag area of the leading cyclist and the interdrafter variability may be due to the drafter's skill in obtaining maximum benefit from drafting.

Consequences of ankle joint fixation on FES cycling power output: A simulation study

Article Abstract:

A study is conducted in which a forward dynamics modeling/simulation approach is used to assess the potential effect of releasing the ankle on the maximal mechanical power output. The result shows that releasing the ankle joint and stimulating the triceps surae and tibialis anterior is expected to result in a modest increase in power output.
