Biomechanics of Running Essay -- essays research papers

Introduction A Qualitative Analysis of leadIn the 1970s, thousands of people took to the road with a new trend of exercise---- footrace. It was clean easy just put one foot in sc becrow of the other as fast as you can and go as far as you can. Feel the burn in your chest? The attempt trickling down your face? The throb in your knees as your foot pounds into the give with every step? Well then, youre exercising Youre path Since then, running has become a dominant factor in sports and fitness a factor so prevalent that the number of musculoskeletal injuries due to running has also increased over the last quarter century. These chronic injuries are usually due to overuse, improper training techniques, or a combination of the two. By using the results of other biomechanists studies, one can extrapolate an thinker of what running should look like and what muscles are utilized during the activity. Consequently, changes in technique, readiness training, and flexibility training ca n be made in night club to decrease the potential for injury.Article SummariesBefore analyzing the mechanics of running, it is important to get together some of the vast research available for this activity. The following are outline summaries of research articles that study various factors on running.DeVita (1994) noted the gait roulette wheel is measured in two ways swing- stance-swing or stance-swing-stance. In this study, electromyogram activity of six muscles was obtained from four subjects while walking and running. The data was amass while the subjects performed a consecutive swing, stance, swing percentage point of each gait. From this, the swing-to-stance and stance-to-swing period of each gait could be measured. The EMG results showed greater activation levels for 5/6 muscles during the swing-to-stance period. Results concluded that the subjects needed to prepare for the initiation of stance and the drill of relatively large external forces and momentums. Therefore, when assessing the human gait, it is best to observe stance-swing-stance. Jacobs, Bobbert, VanIngen, and Schenau (1993) analyze the function of mono- and biarticular leg muscles during the stretch-shortening cycle of running at 6 m/s. Kinematics, ground reaction forces and EMG activities were recorded for a single stance phase. First of all, estimates of muscle force were correlated with origin... ...Reference PageDeVita, P.
