... contribution of muscles and tendons to a given muscle–tendon unit (MTU) excursion. The aims of this study were to (i) compare muscle and tendon excursion between children and adults performing vertical hopping, and (ii) determine whether children and adults choose a hopping frequency that maximizes movement...

... and motor control of landing given their ability to land consistently during bouts of continuous hopping. Previous studies in anurans have shown that ground reaction forces (GRFs) during landing are significantly higher compared with takeoff and can potentially impart large torques about the center of mass...

...Koa N. Webster; Terence J. Dawson SUMMARY We examined the structure–function relationships that underlie the aerobic capacities of marsupial mammals that hop. Marsupials have relatively low basal metabolic rates (BMR) and historically were seen as ‘low energy’ mammals. However, the red kangaroo...

...Edward P. Snelling; Roger S. Seymour; Philip G. D. Matthews; Sue Runciman; Craig R. White SUMMARY The hemimetabolous migratory locust Locusta migratoria progresses through five instars to the adult, increasing in size from 0.02 to 0.95 g, a 45-fold change. Hopping locomotion occurs at all life...

...C. P. McGowan; R. V. Baudinette; A. A. Biewener We examined the functional role of two major proximal leg extensor muscles of tammar wallabies during level and inclined hopping (12°, 21.3% grade). Previous in vivo studies of hopping wallabies have revealed that,unlike certain avian bipeds, distal...

To address this question, we obtained measurements of muscle activation ( via electromyography),fascicle strain ( via sonomicrometry) and muscle-tendon force( via tendon buckles) from the lateral gastrocnemius (LG) and plantaris (PL) muscles of tammar wallabies trained to hop on a level...
