Hopping Motion With SEMG Patterns Lab Analysis

1 . Describe the Major bones, muscles,joints and joint actions used to perform this movement skill and how they influence the way the body moves.

Flexibility is especially important to help with jumps and stunting. Flyers , the people on top of the stunt, should perform different body positions in the air. Some body positions include: heel stretches, arabesques, scales, and scorpions. For jumps, flexibility is required to be able to thrust your legs into the air, pointed and straight. The types of jumps include: toe-touch, hurdler, and pike.

“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).

Jumping (bilateral): Hip and knee is in extension, while ankle is in plantar flexion, and shoulder abduction and flexion while in the air.

Next with a stimulation duration of 50us, the stimulus amplitude should be set to the maximal tolerable stimulus intensity. With stimulus frequency of 2Hz, observe and record the leg movement, increase it by 5Hz but should not exceed 50Hz. With the electrodes connected to the analogy output channel and ground of the DAQ board. With the corresponding LabVIEW program, the frequency and amplitude (voltage) of the stimulation supplied to the leg can be controlled. With this the “sweet spot” of the lowest amplitude and best frequency to cause evoked movement can be found and recorded. Now the stimulation frequency should be set to 10Hz and the duration of stimulation pulse to 5ms or less. The range if leg movement changes can be observed as amplitude changes. Electrical stimulation in increments of 0.01V should be delivered and the minimal voltage required to generate muscle twitch should be recorded. The pulse duration should then be increased by durations of 10ms and the minimum voltage should be recorded this should be repeated for a variety of pulse

Biomechanics is the study concerned with the internal and external forces acting on the human body and the effects produced by these forces (BrianMac Sports Coach, 2014). The purpose of this report is to biomechanically analyse a partner’s Oztag grubber kick by comparing the kick to that of a skilled performer. Oztag is a popular Australian sport, played by many. The grubber kick is a short kick ground, used as an attacking ploy when the player is near the try line. This report will focus on the force summation, Newton’s Laws, levers and balance in relation to the performance of my partner’s kick and will suggest recommendations to improve the success of her kick.

Bonnechere and all’s purpose of writing this article was to “ [share] a biomechanical analysis of three different sprint start patterns to

This experiment was completed in order to compare calf circumference as well as weight to jump height. If a person has larger calves then they will likely be capable of reaching a higher vertical height. It can also be shown that since males tend to have larger calves, they can jump higher. A larger calf circumference is more likely to reflect a high vertical jump due to the fact that the fat content of the calves in the experiment was accounted for, therefore a large calf measurement in this experiment means a muscular calf. It is common knowledge that more muscle will result in stronger legs leading to a higher vertical.

O B J E C T I V E S 1. To define these terms used in describing muscle physiology: multiple motor unit summation, maximal stimulus, treppe, wave summation, and tetanus. 2. To identify two ways that the mode of stimulation can affect muscle force production. 3. To plot a graph relating stimulus strength and twitch force to illustrate graded muscle response. 4. To explain how slow, smooth, sustained contraction is possible in a skeletal muscle. 5. To graphically understand the relationships between passive, active, and total forces. 6. To identify the conditions under which muscle contraction is isometric or isotonic. 7. To describe in terms of length and force the

TA muscle, a crucial muscle for foot lift during gait, and major player in maintaining balance and stability, demonstrated no significant differences during IDS, SS, and TDS on the affected side with the RE as compared to without the RE (P= 0.52780, P= 0.73530, P= 0.07592 respectively), but showed a significant difference during swing as stated above. In the TA muscle, there was no significant differences between the affected and unaffected limbs with RE (P>0.05). While there was no significant differences in EMG activation of the TA muscle without the RE during TDS and Swing, conversely there was a significant difference in IDS, and SS when comparing the affected and unaffected limbs (IDS: P=0.02631, SS: P=0.04539, TDS: P=0.06174, SW: P=0.09960). There was no significant

What are some combinations of movement patterns I can use from one point to another? (Skip, gallop, hop, jump, run, walk, jog, march)

The paper presents the force equation generated by the muscle group, the equation between the moment and the EMG signal. Use software to simulate the dynamics generated by the knee joint. Use the Arduino Uno driver to read signals from the EMG sensor, and store values to the SD card. Using Excel software to process data, create a status chart of the experimenter in knee flexion. The results show that the EMG signal readiness histogram has the same relationship as the dynamical simulation chart with the Matlab software. This is the basis for the calculation of the optimal parameters for the relationship between momentum produced by the muscle group and the EMG signal. In the next study, we will evaluate the baseline levels for patients with

The authors conducted this study to see how and when this ability in humans evolved by studying the mechanics used in throwing. They compared the mechanics of throwing of humans to that of chimpanzees. The authors said that previous studies found that the internal rotator muscles are responsible fort the power of the human throw. The investigators hypothesize that the elastic energy storage is the important source for this power. They also stated that other features of the human shoulder are important in storing this energy and

The kangaroos ability to hop is a structural adaptation. The kangaroo 's leg muscles spring when the kangaroo makes impact with the ground. This transfer from elastic potential energy to kinetic energy saves the kangaroo from using unnecessary energy to cover large distances. (As seen in figure 1)

With no previous experience with engineering, a great deal of my knowledge for the subject comes from studying mathematics, physics and computer science at A-Level. In preparation to study engineering at university, I have decided to read the books “Think like an engineer” by Guru Madhavan and “Cats’ Paws and Catapults” by Steven Vogel. The reason behind this was to grasp the methods in which a skilled engineer would think and enhance basic knowledge about the effects of materials and forces. My aim for the future would be to use my engineering knowledge to create more efficient mechanical limbs that may allow amputees to run and jump. From my reading, I have gained awareness of how natural tendons have certain physical properties that allow them to function efficiently. This include very low strain which allows the animal to rebound without wasting high energy, as the animal takes a stride the tendon compresses and absorbs energy, it then releases it when the animal springs forward. From the books, I have also gathered the difference in the walking and running in terms of motion, energy storage and efficiency. Developing such knowledge at undergraduate level will hopefully
