The purpose of this experiment was to be able to test different intensities of warm-up conditions changes in the heart rate, skin temperature, electromyogram (EMG), and the contraction of the bicep brachii. Testing three different intensity conditions to determine which warm-up is more efficient on muscle conditioning. Bicep stretches, cardio, and aerobic stretching were the three different conditions because they focused on different muscles in the body. The warm-up that is able to efficiently deliver more oxygenated blood to the muscle is the most affective. Therefore, the predictions is that aerobic stretching will enhance muscle performance of the bicep brachii. This will happen because aerobic stretching is a high intensity warm-up that increases heart rate and cardiac output.

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 Physiology of Movement SS4203 Name: Michelle Dullea Student ID: 15156524 Date: 25/11/2016 Lab 2; Characterisation of Joint angle- force Relationship Introduction: The aim of this lab report is to investigate the relationship between external joint angle and muscle force production. We measured maximal isometric strength in the quadriceps and hamstrings using the strain gauge system. The strain gauge allows force produced by the volunteers to be measured in Newtons.
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,
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
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
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
Passively, muscle fibers can become shortened through postural adaptation or scaring. Actively, muscle fibers can become shortened due to spasm or contraption. Stretching has not been shown to be effective at reducing the incidence of overall injuries. While there is some evidence of stretching reducing musculotendinous injuries, more evidence is needed 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.
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
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.
Stretching before a workout is common for athletes. There are four main types of stretching, including dynamic, static, ballistic, and PNF stretching. PNF stands for proprioceptive neuromuscular facilitation. PNF stretching is a great way to help one’s body stretch farther for the task ahead. It is essential for everyone to include PNF stretches in their daily lives because it helps the body become more mobile.
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.
