Unit 5 Group Exercise Lab

In this lab, the focus was to study muscular fitness. In muscular fitness, there are two main components of measurements that are being taken, which are muscular strength and muscular endurance. Muscular strength is an individual’s ability to exert their maximum force. To test muscular strength, there are multiple tests such as 1 RM , Static Handgrip Strength, and Back Strength Dynamometer test. Muscular endurance is an individual’s ability to sustain prolonged muscular contractions. Tests that reveal results about an individual’s muscular endurance would be tests such as YMCA Submaximal Bench Press, Push-Up, and Plank test. It is important to remember that there is no single test for endurance and strength that will tell an

Phase 2: Experimental group training 2. During this phase, only the experimental group will meet to perform a second round of training using CN. The teachers will use the same sample topic and administer the lecture, only this time the teachers will not stop or answer questions during the note-taking session. Once the lecture is completed, the students will pair up with a partner to review their notes and make adjustments to their notes as needed. Then, the classes with discuss their results from the partner time and make any further adjustments to their notes as needed based on the class discussion. The teacher will again collect the training notes for the researcher and answer any remaining questions as indicated.

The subject will start pedaling one the subject get a rhythm the resistance will increase to 1 kp for women and 1.5kp for men. Once the resistance is added the time will begin. The subject will pedal 3 minutes at 50 rpm at the tree minute mark the subject heart rate will be recorded. Depending on the heart rate the resistance will increase or decrease. The subject will keep on pedaling at the five minute mark the subject heart rate will be recorded. Then at the six minute mark the subject heart rate will be recorded against. There must be a 10 bpm difference between the heart rates, so if it is higher than 10 the subject will keep on pedaling until it is between those

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 sit and reach test is a measure of flexibility, of the lower back and hamstring muscles.First, I removed my shoes, I placed a regular sized box in front of me making sure that my left foot was placed right in the edge of the box. My brother placed a yardstick taped on top of the box making sure that the first nine inches are away from the box and facing me. I bend my right knee and keep my left knee straight. I placed one hand on top of the other in front of me with my palms facing down. I reached forward as far as I could go making sure that my back and neck was straight and my head up. I repeated this stretch three more times holding my last reach for three seconds while my brother records how far I went. I repeated this same stretch

My client performed the Arm Curl, Chair Stand, Push Up, Standing Heel Raise, Unilateral Step Down, Single Leg Stance Eyes Open, Single Leg Stance Eye Closed, Standing Stroke, Four Square Step, Time Up and Go, Four Meter Walk Velocity, and Two-Minute Walk Test. He scored 28 reps in 30 seconds for the Arm Curl Test. In the Chair Stand Test he recorded 50 reps. In the Push Up Test he was able to do 31 reps. In the Standing Heel Raise Test he was able to do 31 reps for the left foot and 32 reps for the right foot. In the Single Leg Stance Test with eyes open he recorded 90 seconds on both legs. With eyes closed he recorded 9 seconds on his left leg and 8 seconds on his right leg. In the Standing Stroke he got 3 seconds for both right and left legs. For the Four Square Step Test he had three trials. He finished in a time of 4 seconds for one, 3.9 seconds for the other and had 1 miss trial. In the Time Up and Go test he completed it in 3.8 seconds. For the 4-Meter Walk Velocity Test he completed it in 1.72 seconds and had a speed of 2.33m/s. In the 2-Minute march test he completed 92 reps.

3) After practice repetitions, you will perform five repetitions at your maximal effort of the leg extension, your peak strength on a clinical strength-testing machine. You will also perform three maximal effort contractions on the handheld dynamometer in each hand.

Plyometric exercise protocol was the exercise used to induce muscle damage. The participants did ten sets of ten plyometric drop jumps. Following the plyometric exercise protocol, the participants drew sealed envelopes that gave them their group assignment. The participants’ EIMD were then observed and documented at 1, 24, 48, 72, and 96 hours after exercising by looking at four assessments: jump performance, isokinetic muscle strength, perceived muscle soreness, and blood markers. The researches studied the participants’ jump performance by measuring their squat and countermovement jump height with a vaned jump and reach apparatus. Isokinetic dynamometry was used to determine isokinetic muscle strength. The participants were sitting upright with their experimental leg secured to avoid any other movements besides what’s being tested. The dynamometer measured the concentric contractions at 60° and 180° s-1 through 90° range of movement. Perceived muscle soreness was measured by having the participants squat at 90° and then report their soreness on a scale of 0-10, with 0 meaning no pain and 10 meaning the worst pain ever. Blood was also tested to assess EIMD. A 6-ml venous blood sample from the antecubital vein was taken and then centrifuged for ten minutes to get a sample of the blood

The purpose of the experiment in lab 5 was to see how force and EMG of the muscles would be affected when the wrist angles were changed. In order to determine how much the myosin and actin were interacting and how many times the muscle cell was stimulated we had to measure the force. When the wrist was fully flexed at 90-degrees the muscle was more contracted. Therefore, causing the sarcomere to be pushed closer together and the zone of overlap to be larger. This causes the myosin and actin to be on top of each other making it more difficult to have a quality cross bridge formation. This makes it harder to stimulate the muscle. As we continued to squeeze at different angles the force would get greater as the angle became more flat. We had the

All participants in the study were both the experimental and control groups. The sessions were separated by four weeks; the sessions were randomly assigned to the participants. The testing sessions included an orientation with 1RM squat and practice of each test, followed by four conditions four weeks apart. The participants warmed up on the cycle ergometer then completed the DOMS protocol. Data was analyzed using magnitude-based inferences. Baker et.al

Observe and document the patient’s response to activity. Evaluate the patient’s response to walking for several minutes observing HR, BP and O2 saturation. If patient demonstrates good outcome, progress to observing stair climbing.

Lu, Chien, Chang, and Hsu had two primary purposes for their study. These purposes were to determine if an examiner’s strength have an affect on the validity of knee manual muscle testing (MMT) strength measurements using a hand-held dynamometer (HHD), and whether increasing the forces applied by an examiner using a resistance-enhanced dynamometer (RED) would positively affect measurement validity.

For this experiment, we will be examining the strength of the summation of both the dominant and non-dominant hands of the subject pool by the use of a dynamometer. The dynamometer measures the total strength of the muscles located in the hand and forearm. For this exercise, the dominant hand refers to the hand an individual generally uses to perform fine motor skills, while non-dominant indicates the hand an individual does not use for fine motor skills. Due to the involvement of the muscles in the wrists, hands, and fingers needed in the execution of fine motor activities the force generated by the dominant hand will be greater than the force created by the non-dominant hand.

We hypothesized that asymmetry will exist in both a 2 mile and 4 mile run, and that the loading patterns will change as the subject fatigues. Each runner was asked to complete a 2 mile run and a 4 mile run at least one week apart. The loading data was recorded using Novel’s pedoped application on an iPod Touch throughout the run. After the completion of the run, the loading data was extracted using a custom Matlab script from 20 step intervals at three time points (25%, 50%, and 75% of the total run). In order to assess changes in symmetry, the limb symmetry index (LSI) was calculated between limbs on subsequent steps at each time point. The impact peak LSI is the absolute value of the difference in impact peak between limbs divided by the mean impact peak multiplied by 100 percent. The average of the LSI for each time interval during each of the runs was calculated, and differences in side-to-side asymmetry were analyzed between genders and between runs. Thirty subjects will be recruited by the completion of the study. Currently, seven females and twelve males have been tested for the

The limitations of this study were that the participant only had a five meter run up to the force plate. This led to the participant struggling to land his dominate foot on the force plate and also the participant only had 60 seconds to complete all 3 trials with changing of the shoes and running on the force plate. Another limitation from this study is that speed. The speed was required to be the same for all 3 trials, however, the participant couldn’t maintain the constant level as he started to become fatigue towards the ending of the
