There are two main phases to the running cycle: Support and Forward Recovery



Support Phase: This is the phase when the runner is touching the ground, and makes up about 30%-40% of the running cycle.

Foot-strike: The foot touches the ground slightly ahead of the center of mass. When the foot contact occurs, several actions take place: the knee flexes, the tibia internally rotates, the ankle plantar flexes, and the subtalar joint pronates (Miliron & Cavanagh, 1990). It is necessary to have a certain amount of pronation to disseminate the energy of the foot-strike. The foot during the foot-strike should be straight and in line with the direction of linear motion. If the feet are turned outward it reduces the distance covered, and puts more stress on the knees and lower extremities (Williams, 1990).

Mid-support: The foot transforms from a mobile structure into a rigid lever that supports several times the body weight of the runner. The shape of the bones and the tension on the ligaments, allows for the foot to remain rigid. The supination of the subtalor joint forms a rigid lever for forward propulsion. This occurs through a series of events including the knee joint extending, the lower extremity rotates externally, the calcaneus inverts, the midtarsal joint locks, and the foot becomes a rigid lever.

What is Supination? This is the opposite motion of pronation. This occurs when the ankle appears to be 'tipped' to the outside so the weight is on the outside border of the foot. Supination allows the foot to be a more stable, rigid structure for pushing off of. The foot naturally supinates during the toe-off stage (when the heel first lifts off the ground until the end of the step) to provide more leverage and to help ‘roll’ off the toes.





Take-Off: The the mid-support period ends with an uprising heel, and is called the take-off period.

Forward Recovery Phase: This is the phase when the runner is airborne and spends most of the time.

Biomechanics of Running Essay

- Introduction: A Qualitative Analysis of Running In the 1970's, 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 far 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 step. Well then, you're exercising. You’re running. 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....   [tags: essays research papers]

The Environment Of The Water Cycle Essay

- The water cycle also gets affected from human interaction with the environment. When we urbanized places we affect the ground water, which in turn affects the water cycle. Urbanizing areas and putting companies and gas station’s that produce waste is not good for the water cycle. The pollutants from these places seep into the ground and pollute the groundwater and make it harder for that water to come back to the surface clean. It takes years for this to naturally occur and when we interact with it like that it takes even longer and affects the cleanliness....   [tags: Earth, Global warming, Pollution, Climate change]

Essay on Thermodynamic Cycle Of A Hp

- A HP is thermodynamic cycle which is designed to use both heating and cooling functions. A thermodynamic HP cycle transfers heat from one reservoir (air) to another reservoir (water). There are four components of a HP which are evaporator, compressor,condenser, and expansion valve. The evaporator is a device like heat exchanger situated in the first reservoir. This evaporator makes possible heat from first reservoir in order to be transferred to a cold low pressure refrigerant. This heated refrigerant flows into the compressor to increase its pressure, causing an increase of the temperature....   [tags: Heat, Thermodynamics, Energy, Water heating]

Essay on Knowing Macau with Butler's Life Cycle Model

- Knowing Macau with Butler's Life Cycle Model The following literature is suggesting that how a tourist destination can be analyzed with the help of Butler's Tourism Life Cycle Model. Butler (1980) introduced the concept of the model which clarifies and extends earlier work by, for example, Cristaller (1963), Noronha (1976) and Stansfield (1978). In doing so, Butler clearly links the development cycle of tourism destinations to that of products in the product life cycle model. This is one the best used management framework to know the evolution in a tourism destination as described by Baum (1998), the original Butler's model included: • Recognition of dynamism within the tourism environment...   [tags: Tourism Industry Macau Life Cycle Model Butler]

The Significance of the Nitrogen Cycle in Ecosystems Essay

- The Significance of the Nitrogen Cycle in Ecosystems Nitrogen makes up about 80 per cent of the Earth's atmosphere as a gas. However the gaseous molecule is very stable and has to be transformed before it can be used by most organisms as it is only available to them when it is ammonium or nitrate. It can only be removed from the atmosphere in two ways: by lightning and by nitrogen fixation. Only a few species can convert nitrogen by nitrogen fixation to biologically useful forms....   [tags: Papers]

Organizational Life Cycle Essay

- Running head: ORGANIZATIONAL LIFE CYCLE Organizational Life Cycle Organizational Life Cycle Organizations go through different life cycles similar to those of people. For example, people go through infancy, child-hood and early-teenage phases, which are characterized by rapid growth over a short period of time. Similarly, Organizations go through start-up, growth, maturity, decline, renewal and death. Employees in these phases often do whatever it takes to stay employed. (Ciavarella, 2001) In the start-up phase of an organizational life cycle, employees are eager to make a name for themselves and often act impulsively, making highly reactive decisions based on whatever is going o...   [tags: essays research papers]

Analysis of the Elements of the Intelligence Cycle Essay

- Minor Assignment • Analyse the elements of the ‘Intelligence Cycle’. What are its core strengths and weaknesses. Before I begin to analyse the elements of the Intelligence Cycle, I must begin with the definition of ‘Intelligence’. Throughout my research, it became apparent that the acceptance for an accurate definition of ‘Intelligence’ is still an issue to date. One reason could be because experts tend to view ‘intelligence’ through their own specialty, and would be fair to say that this could possibly be because officers within the intelligence community do not have strong bridges connecting them to each other or to policy makers, which would therefore enhance communication and sharing...   [tags: Intelligence]

- The Grief Cycle in Real Life Lost and hopeless, with a situation entirely out of my control. Those are some of the feelings I had upon moving from Kansas to California, during the summer of 2006. This dramatic change in my life was very startling and I had to come to the realization that even though this would be an extremely hard time in my life, I could have hope that God has a plan for me and that everything happens for a reason. All the bargaining with my parents to remain living in Kansas, the anger and animosity built up towards them, the depression that long-lasting friendships would be shattered and lost, were all normal steps in the process of the Grief Cycle....   [tags: lost and hopeless, denial, anger]

Forward swing: This is a continuation of the follow-through. Knee flexion assists in the flexion of the hips, allowing the thigh to move horizontally and the runner to prepare for a foot-descent.

Foot-descent: This occurs after maximum hip flexion is reached. The knee now extends after flexing to allow movement of the lower limb. the hamstrings are the opposing muscles that slow forward movement of the foot and leg by generating tension.
