T summer of 1949 was long and dry in Montana. On the afternoon of August 5th—the hottest day ever recorded in the state—a lightning fire was spotted in a remote area of pine forest. A parachute brigade of fifteen firefighters known as smoke jumpers was dispatched to put out the blaze; the man in charge was named Wag Dodge. When the jumpers left Missoula, in a C-47 cargo plane, they were told th...

ABSTRACT Introduction The research on the exercise effect human bone density and skeletal muscle content mainly focuses middle-aged elderly population. However, few studies different sports’ effects upon in college students adolescents. Objective Study of physical training lower limb jumping ability young people. Methods relationship between mineral was analyzed by mathematical statistics. Male...

This study used functional magnetic resonance imaging (fMRI) to investigate differences in brain activity between one group of active high jumpers and one group of high jumping novices (controls) when performing motor imagery of a high jump. It was also investigated how internal imagery training affects neural activity. The results showed that active high jumpers primarily activated motor areas...

purpose: over the past 20 years, the center of pressure (cop) has been commonly used as an index of postural stability in standing. while many studies investigated cop excursions in patients with knee osteoarthritis and healthy individuals, no comprehensive analysis of the differences in their postural sway pattern exists. the present study aimed to review the previously published studies conce...

The purpose of this study was to evaluate the extent to which residual shank length affects long jump performance of elite athletes with a unilateral transtibial amputation. Sixteen elite, male, long jumpers with a transtibial amputation were videoed while competing in major championships (World Championships 1998, 2002 and Paralympic Games, 2004). The approach, take-off, and landing of each at...

background and objectives: it has been shown that a bout of jumping exercise with weighted vests increases the subsequent countermovement jump height. however, it is not clear whether the improvement in jump height is due to the enhancement of joint power or due to other mechanisms such as neural adaptations. methods: to investigate this dichotomy, we tested the acute neuromechanical changes fo...
