Biomechanics of Running Essay -- essays research papers

Introduction A Qualitative Analysis of RunningIn the 1970s, thousands of people took to the road with a new trend of exercise----running. It was fairly easy just put one foot in front of the other as fast as you can and go as furthest as you can. Feel the burn in your chest? The sweat trickling down your face? The throb in your knees as your foot pounds into the ground with every cadence? Well then, youre exercising Youre running Since then, running has become a dominant factor in sports and fitness a factor so frequent 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 facts of life techniques, or a combination of the two. By using the results of other biomechanists studies, one can extrapolate an idea of what running should look like and what muscles are utilize during the activity. Consequently, changes in technique, strength training, and flexibility traini ng can be made in order to decrease the potential for injury.Article SummariesBefore analyzing the mechanics of running, it is all-important(prenominal) to accumulate some of the vast research available for this activity. The following are brief summaries of research articles that study various factors on running.DeVita (1994) noted the gait daily round is measured in two ways swing-stance-swing or stance-swing-stance. In this study, EMG activity of six muscles was obtained from four subjects date walking and running. The data was collected while the subjects performed a consecutive swing, stance, swing period 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 cogitate that the subjects needed to prepare for the initiation of stance and the application of relatively large external forces and momentums. Therefore, when as sessing the human gait, it is best to observe stance-swing-stance. Jacobs, Bobbert, VanIngen, and Schenau (1993) analyzed the function of mono- and biarticular leg muscles during the stretch-shortening regular recurrence 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 fit with origin... ...Reference PageDeVita, P. (1994).
