An acute bout of static stretching: effects on force and jumping performance

Article Abstract:

A study is conducted to examine whether a static stretching (SS) routine decreased isometric force, muscle activation and jump power while improving range of motion (ROM) and to compare the duration of dependent variable changes with the duration of the change in ROM. The conclusion states that parallel duration of changes in ROM and quadriceps isometric force might suggest an association between stretches induced changes in muscle compliance and isometric force output.

Difference in mechanical and energy cost between highly, well, and nontrained runners

Article Abstract:

A study is conducted to compare the mechanical and the energy cost of running according to the training status of the highly, well and nontrained endurance runners. The conclusion states that although there is a significant difference in C(sub pe) and in C(sub int) between runners of various training status, there is no difference in C.

Transferability of strength gains from limited to full range of motion

Article Abstract:

The transferability of short range of motion (RoM) isokinetic conditioning on quadriceps performance inside and outside the trained range is explored. The finding suggests that potential benefits of short (RoM) conditioning, particularly in those cases where during specific phases of rehabilitation, a wider RoM may be contraindicative.
