Is Running A Natural Form Of Human Locomotion?

The knee joints is one of the primary joints stressed when running and thus most of the

“The analysis of movement provides an athlete with optimal development as well as minimising the risk of developing injuries through the incorrect execution of a movement” (Ackland, Elliott & Bloomfield, 2009, p 301).

Dr. Delp’s research analyzes muscle movement, structure, and purpose with the use of model simulations mechanisms and other software technology. In Running with a load increases leg stiffness, it is identified that added loads to the body impacts running posture, causing crouching of the body, and does contribute to higher leg stiffness. In line with Dr. Delp’s talk today of the “Dynamics of walking and running,” a comparison is established between both types of movement and the authors delve into how each are impacted when under a load (ranging from 10-30% body fat). Subjects walking and running under a load, compared to zero load, were to found to have longer ground

The participants ran for five minutes at there own pace to warm up. To randomize the order the participants were randomly assigned which condition to complete first, barefoot vs. shod. During the experiment the participants ran for two minutes at 3.05 m*s^-1, rested for two minutes, then ran for two minutes at Then had a two-minute rest period and completed the same procedure for the other condition. Each participants stride length was assessed using the distance measured between the first and second initial contact of the left foot.

The ankle joint is the most commonly injured part of the body for individuals who participate in competitive activities, accounting for approximately 30% of all sports related injuries (Boyas, Hajj, & Bilodeau, 2013; Hootman, Dick, & Agel, 2007; Waterman, Owens, Davey, Zacchilli, & Belmont, 2010). It was estimated that in the United States alone, there are around 25,000 ankle sprains suffered each day(Olmsted, Vela, Denegar, & Hertel, 2004). A systematic review has analyzed articles published between 1977 and 2005 in 70 sports, and demonstrated that the ankle was the

Azevedo et al. (2009) has found that knee range of motion (heel strike to midstance) was significantly lower in injured runners with Achilles tendinopathy than in uninjured runners. In adition, the preactivation (EMG) in 100 ms before heel strike of tibialis anterior was lower for injured runners than uninjured runners. Moreover, rectus femoris and gluteus medius IEMG activity 100 ms after heel strike was also lower in the injured group.

Biomechanics is a field that looks into the structure and function of biological systems such as humans; it can be used in numerous fields. It ranges from aiding in sports performance to helping people with daily tasks such as walking. Majority of sport related occur in the lower extremities. Lower extremities include the hip, knee and ankle joints and the femur, tibia, fibula, and multiple foot bones. This paper will focus on the role of the ACL, how it is injured, and the rehabilitation process. While each component of the lower extremity has its own role, the knee is the most complex. The knee joint performs various functions and carries most of the weight of the upper body. There are four ligaments in the knee joint: the anterior

Running does not only help you get in shape or stay fit, your body has to also be in good condition while continuously doing it. Running causes many unpredictable and unfortunate injuries. Things such as Runner's Knee, Stress Fractures, Shin Splints, Achilles Tendinitis, and any Muscle Pulls. All of these things happen when you least expect them to. Why do these injuries occur and what can we do to prevent them? Don't get me wrong, running is a fast and easy way to lose weight, also very good for your health. There are just a few things you have to look out for when doing it. Recent research has shown that as many as 79% of runners get injured at least once during the year. That is nearly 8 out of every 10 runners you see at every race.

Participants will need to be unattached cross-country or marathon runners who run a minimum of 15 miles a week. The runners must already be accustomed to wearing stability-type running styles excluding the styles used in the study and are not dependent on orthotics for support. They must not currently have or have had any lower body musculoskeletal injuries within the past year, and must visibly over pronate with longer heel-to-ball measurement than heel-to-toe, indicating a flat arch. Only men with size 10 and 12 feet, and women with 8 and 9 can be included due to

The basic gait parameters most frequently used are velocity, step length, and step frequency. Many reports are concerned with pathological gait, but such data must be compared with valid normal reference data to be interpretable. The aim of this study was to compare the participant’s present reference data with basic gait parameters for normal subjects. The experiment involved one voluntary male Exercise and Sport Science student aged 20 with a history of numerous ankle injuries in the last 2 years. The participant weighs 72kg and is 1.76m tall with both legs measuring at 97cm.

A model of running is proposed in which the leg is represented as a rack-and-pinion element in series with a damped spring. The rack-and-pinion element emphasizes the role of descending commands. While the damped spring represents the dynamic properties of muscles and the position and the rate sensitivity of reflexes. This model is used to predict separately the effect of track compliance on step length and ground contact time. The predictions are compare with experiments in which athletics ran over track of controlled spring stiffness. A sharp spike in foot force up to 5 times body weight was found on hard surfaces, but this spike disappeared as the athletes ran on soft experimental tracks. Both ground contact times and step length increased

Foot injuries are very common in athletics as well as in everyday life. It’s very debilitating to have a foot injury since we use our feet in all of our daily activities. Research published in "Medicine and Science in Sports and Exercise” indicates that the average adult takes between 5,000 to 7,000 steps a day. Some sports require the most dedicated athletes spend multiple hours a day pounding their feet on the turf or pavement. Most injuries that occur in the foot require a person to try and stay off of it or completely immobilize it. Since this is very difficult for a person to do, a large percentage of foot injuries often have a very high chance of reoccurring. The severity of some injuries that can be deceiving as well. Often times a nagging pain is ignored and eventually becomes a much bigger problem.
