The constant battering with every stride takes its toll over the course of the endeavor. The activation of both fast and slow twitch muscles on one’s quadriceps, hamstrings, and calves introduces a new level of stimulation and fatigue to the legs. Something the body almost never experiences. With added stress fractures being common on runner’s shines and feet. And both your heart and kidneys working overtime to keep the machine that is your body running.
Research and studies can always be attempted again, with new information being applied in order to make the study even better than previously
Mc Morris and Hale refer to Witvrouw et al. , (2004) in explaining the reason behind the conflict in findings and like Gilbert and Mc Hugh (1997), states that it is the type of nature of the sport that determines whether flexibility will affect the risk of injury. However, they explain this further by stating that the rate of stretch shortening cycle determines the effectiveness of flexibility. A high rate means that the muscle is required to be compliant in order to react quickly. With a slow rate, this is not necessary therefore flexibility does not have much impact (Mc Morris and Hale,
Unfortunately, not many studies have been done on the
However, the success of researchers has been limited as the
Stretching is to lengthen your tight muscle so that when you are exercising, you are not limiting your muscle’s Range of Motion (ROM). Cramps or muscle tightening during exercise occurs because there are some muscle that are not fully straighten before exercising and the individual has put extra force on that particular muscle which has exceeded the muscle’s ROM and in some cases, the muscle strains. Stretching before exercise is to extend muscle range of movement which makes an athlete jump higher or run further without hurting
Often times, as ridiculous or unacceptable as some of these experiments may seem, unfortunately some of them have success. For example, when it comes to Edward Jenner the man who developed the smallpox vaccine, in his early workings he injected a child with some pus he had taken from a cowpox infection. Following up with the injection, he then proceeded to expose the child, “…to an infected carrier of smallpox” (The Conversation). Yes the trial helped with making a breakthrough, but it was also very risky considering he exposed a child to a very deadly disease.
Experimentation on humans, while sometimes beneficial, often has resulted
For example, research from Dr. Lawrence Kendo in U.S shows that:
