Changes in the mechanical properties of human quadriceps muscle after eccentric exercise.

30 Aug 2009 Muscular adaptation which occurs following eccentric exercise-induced muscle damage has been associated with changes in the mechanical properties of muscle manifested as a shift in the length-tension relationship towards longer muscle lengths. ... Read more...

Effects of dietary intervention and quadriceps strengthening exercises on pain and function in overweight people with knee pain: randomised controlled trial.

16 Aug 2009 OBJECTIVE: To determine whether dietary intervention or knee strengthening exercise, or both, can reduce knee pain and improve knee function in overweight and obese adults in the community. DESIGN: Pragmatic factorial randomised controlled trial. ... Read more...

Differences in activities of the lower extremity muscles with and without heel contact during stair ascent by young women wearing high-heeled shoes.

5 Aug 2009 BACKGROUND: The purpose of this study was to identify any differences in the activity patterns of lower extremity muscles with and without heel contact during stair ascent by women in their twenties wearing high-heeled shoes. METHODS: Twenty healthy ... Read more...
