Thesis: An analysis of the effects of static and dynamic stretching on power and performance.
Stretching is a vital component for warming up prior to exercise. It reduces the risk for injury by increasing flexibility and range of motion. Warm-ups generally consist of aerobic exercise followed by static stretching. The goal of warm-ups have been to increase body and muscle temperature which in turn increases nerve conduction velocity, enzymatic cycling, and muscle compliance (Behm & Chaouachi, 2011). There are also a variety of non-temperature related factors that occur during warm-ups. These include an increase in blood flow to the muscles, increase

Power is the rate of external work and it is calculated by propulsive force movement speed (Edwen et al., 2014). Franco, Signorelli, Trajano, Costa, and Oliveira conducted research regarding the effects of static stretching on a variety of anaerobic test. The participants performed five different types of static stretching for five minutes and then performed the test. The results showed a decrease in strength and power that can be attributed to greater muscle elasticity, as well as a decrease in the cross bridge movement (Franco, Signorelli, Trajano, Costa, & Oliveira, 2012). Franco et al. (2012) discusses another study conducted by Edman and Tsuchiya. The research concluded elastic titin was an influencing factor in passive stretching. Due to its function of providing adjustments of passive tension, it is hypothesized to be the main structure responsible for muscle elasticity (Franco et al., 2012). In return, this can cause a decrease in muscle spindles and low activity level of alpha motor …show more content…

Six different subjects all between the age of 21-25 from all different physical levels performed four experiments. Each experiment consisted of two sessions a warm-up and lifting both a 10 lbs and 15 lbs dumbbell with a two-minute break between the two loads. The warm-ups were bicep stretches, which involve three different stretches and lasted for about 30 seconds each for a two-minute stretch, cardio, which included step up until max heart rate was
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
Flexibility can be defined as the capability of something to bend easily without breaking. The flexibility of a person is commonly measured during fitness tests, and the most frequently used test of a person’s flexibility is the sit-and-reach (Jackson and Baker, 1986). Though it is commonly accepted that the sit-and-reach produces an accurate and relative measure of a person’s flexibility, the validity of the test has been examined a number of times (Jackson and

When athletes or bodybuilders stretch they can actually lose most or some of there muscles power making there performance worse. Scientist have even done a experiment on this because they got a group of people from the age of 19-25 and they had one group stretch and the other group did not
Charles Darwin, an evolutionary scientist, who once said, “it is not the most intellectual of the species that survives; it is not the strongest that survives; but the species that survives is the one that is able best to adapt and adjust to the changing environment in which it finds itself”. In Jack London 's book The Call of The Wild, out of many themes the most important is adaptation for many reasons. Buck has adapted mentally and physically, Buck 's original character was changed very quickly after arriving in the cold Alaskan wilderness. Buck adapted in many ways throughout the book and this helped him greatly in surviving and becoming the lead sled dog and eventually a giant “ghost dog”.
The athlete began to heat the injured area before beginning his exercise to help promote increasing range of motion. Both active and passive stretching of the elbow and wrist assists the athlete in increasing range of motion as well. The athletic trainers added hammer pronation/supination exercises to
Measures of training load had inconsistent effects on changes in tendon structure; eg, there were possibly to likely small positive effects on the structure of the nondominant Achilles tendon, likely small negative effects on the dominant Achilles tendon, and predominantly no clear effects on the patellar tendons.
In the designed static stretching exercises the participants were supposed to stretch the leg extensor muscle of the dominant thigh. Four types of static stretching exercises (one unassisted stretching exercise followed by three assisted stretching exercises) were planned for this study. Each participant performed four repetitions of each static stretching exercise. The stretch was held for 30 seconds at a point of mild discomfort, but not pain. There was a 30 second rest period between each stretching repetition.
Stretching is a simple exercise that combines the bone and muscle components of the last two therapies. Also, stretching is a common daily activity; therefore, it is an easy and effective therapy treatment. The journal, Clinical Biomechanics (2013) decided to study the effectiveness of stretching on children with cerebral palsy. This source, written by researchers sharing the interest of pediatric biomechanics, claimed, “Children with spastic cerebral palsy experience increased muscle stiffness and reduced muscle length, which may prevent elongation of the muscle during stretching” (Theis, N., Korff, T., Kairon, H., & Mohagheghi, A., 2013). They believed stretching increases and maintains, joint range of motion. Thus, they created a study
I made sure that each and every stretch was held for 30 seconds and for each all were held to point of tension. To finish the session plan I included static stretches, as many sports people can suffer from tightness in particular muscle groups and due to this it may require stretches to be held for longer than what is needed in dynamic stretching. Static stretching also helps to improve flexibility and the more flexible a muscle is then the less likely it is to tear and the greater more it can exert greater force then the performance will be enhanced.
I generally use static stretching on my own. I do not go a gym or participate in any exercise routine. In the morning while getting ready for work. This help prepare my body for the drive and daily movement. Throughout the day I stretch my thigh muscles, since I wear high heels. Sometimes I take off my shoes and stretch my calf muscles. During high school the gym teachers would always incorporate ballistic stretching into the class. While it did not hurt, I was scared I would tear something. I think starting to include dynamic (functional) stretching as one ages would help to maintain stability as they grow older. As people age they lose some of the balance and this would help at least keep their body prepared for movements. This stretch
When you are a dancer, or any other type of athlete, stretching is the number one most important part of your performance. Before any performance or game, every athlete should dedicate a good amount of time to stretching, and they should be giving their full attention into stretching. The purpose of my investigation is to test how the amount of time an athlete spends stretching effects how low their splits are. This topic is really important to dancers and gymnasts or especially because when you perform its very important to stretch before performing even the most basic tricks, like splits or a heel stretch. Not stretching can lead to soreness, and pulled muscles which in certain cases can keep you from participating for weeks,
Milton Keynes residents have many reasons to take driving lessons. This area of Buckinghamshire is a popular choice for businesses who want close proximity to London, located 45 miles away. As a result, there are lots of corporations and jobs in Milton Keynes. The opportunities for work are one reason why people embark on driving lessons in Milton Keynes. The number of attractions in Milton Keynes also makes learning to drive worthwhile.
Richard Kuklinski, known as the “ The Iceman” was an American contract killer and serial killer. He was born in 1935 in New Jersey and suffered a rough childhood leading him to commit his first murder at the age of 14. Because of his lack of education he was forced to find a living as a hitman for the Genovese, Gambino and DeCavalcante families. He got his nickname, "The Iceman", for his method of freezing victims to obscure their time of death. Richard Kuklinski was convicted of two murders but claimed to have killed at least 200 others.
