For the study conducted this week‚ the group formed two hypotheses over two different tests that were ran. For the first test‚ which was ran using a hand dynamometer to measure grip strength‚ it was hypothesized that while listening to two different types of music‚ classical and rock‚ and measuring the executed force with the hand dynamometer every 15 seconds‚ that when listening to rock music‚ the individual will show less fatigue of the forearm muscle throughout the song than when listening to

Cussons P9050 Two Stage Reciprocating Air Compressor Test Set is used in this experiment. In the beginning the system is set up to a single stage air compressor and it is operated at a constant speed. Then‚ by manipulating the air receiver‚ the dynamometer load‚ the inlet air flow orifice manometer reading‚ outlet and inlet temperature are recorded. From the results gathered‚ the values of air flow‚ power output and efficiencies are calculated. Three graphs representing the relationship between the

was conducted in order to observe the recruitment of motor units during a muscle contraction in which increasing grip force was applied using the dynamometer in steps up to 40kg. The second part of the lab dealt with determining the time it took for 50% muscle fatigue to occur when maximum grip force was applied to the same muscle using the dynamometer. All results were recorded in the lab notebook for subsequent analysis. Results In Figure 1‚ we can see that as increasing grip force is applied

2/14/2012 Anatomy and Physiology Muscle Grip Strength Lab Report Introduction: Skeletal muscle is a form of striated muscle tissue existing under the voluntary control of the somatic nervous system (Medscape 1). Skeletal muscle is part of the three big muscle types‚ it is connected to bones by tendons (Medscape 1). Muscle grip strength is significant to an individual because it helps the person know the ability of muscle power and force that they have in their

Methods The lab equipment included a hand dynamometer‚ electrodes lead set and the computer program. We placed three electrodes to each forearm of the subject. First we began with the subject’s dominant forearm. We recorded a cycle clench-release-wait‚ holding for two seconds and releasing for two seconds before beginning the next cycle. This is when the subject began to increment force as assigned (10‚ 20‚ 30 kg). Then the subject clenched the hand dynamometer with maximum force until the maximum displayed

force we can apply against a force The handgrip test is a common way of measuring the subject’s strength. The subject holds the dynamometer in the hand to be tested‚ with the elbow side by side of the body. The handle of the dynamometer is adjusted if required‚ while the handle should rest on middle of four fingers. When ready the subject squeezes the dynamometer with maximum effort‚ which is maintained for about 5 seconds. No other body movement is allowed. The subject should be strongly encouraged

increments. During the MIL assessment‚ each subject was tested using a spring-loaded dynamometer attached to a level wooden platform. The range of operation was 0 lb (0 N) to 660 lb (2.932 N)‚ with 5-11lb (22.22-N) increments. The subject was instructed to stand on the platform‚ pick LIP the dynamometer handle‚ and pull upward on the handle as much as possible without causing pain or modifying existing symptoms. The dynamometer handle was fixed at 38.1 cm (15 in) from the platform base in order to standardize

Strength Grip Dynamometer: The purpose of this test is to measure the strength of the forearm muscles. The only equipment you need is the handgrip dynamometer. The participant has to hold the dynamometer in their hand to be tested‚ with the arm at right angles and the elbow by the side of the body. The base of the dynamometer should come into contact with your palm and your 4 other finger should go into the gap and this will make you go into a fist position. You must then squeeze the dynamometer as hard
