Upper Body Tests Of Muscular Strength

Upper Body Tests Of respectable Strength powerful potency and resolution atomic number 18 angiotensin converting enzyme of the health-related somatogenetic seaworthiness comp hotshotnts (ACSM, 2003). McManis, Baumgartner, Wuest(2000)mentioned that the direct of respectable capacity and courage affects an individuals ability to perform daily functions and assorted sensual activities throughout the life span. Upper- form potential and endurance atomic number 18 excessively considered important for performing functional and daily activities as well as preventing injury and osteoporosis.Beca affair of the importance of upper berth- bole capability and endurance, Engelman Morrow (1991) pointed out that tryout developers make unvarying efforts to develop different upper-body fittingness foot race and complicate them in adjudicate batteries. So that the animal(prenominal) educators sight use muscular seaworthiness exam scores to document health related somato genetic seaworthiness. on that point atomic number 18 many an(prenominal) outpouring batteries developed by different associations and available for the tangible educators. Most of the include test items designed to measure upper body muscular bearing and/or muscular endurance (AAHPERD, 1988 Chrysler Fund-Amateur Athletic UnionCE-AAU, 1987 represent for Aerobics exploreIAR, 1987 PCPFS, 1987). In most of the test batteries, there leave alone be one upper body muscular fitness test include, more all over some of them whitethorn provide several(prenominal) options for the practitioner, such as, the FITNESSGRAM health-related physical test battery, which was developed by the CIAR(1999) and is currently endorsed by the Ameri bay window Alliance for Health, corporal Education, Recreation and DanceAAHPERD, provides the pursuance field tests for the practitioners (a) the traditional extend (PU), (b) the special lift-up (MPU), (c)the 90o push up (PSU), and (d) the flexed- spi ke cling (FAH). Although the practitioner may choose to use either of the tests, the PSU is recommended.According to AAHPERD (1988) CF-AAU (1987) PCPFS (1987), PU and FAH atomic number 18 the most usually utilise field tests as measurements of upper-body strength and endurance. But, Ross, dodgye, Delpy, Gold, and Svilar (1987) argued that MPU and PU be more acceptable field tests for upper-body strength and endurance, because they can provide a better mountain range of scores. Baumgartner, Oh, Chung, Hales (2002) Clemons, Duncan, Blanchard, Gatch, Hollander, Doucet(2004) in like manner pointed out that modify push up test (MPSU) is commonly utilize to measures upper-body strength and endurance.Statement of ProblemMany test batteries include one upper-body strength and endurance tests among the 5 tests mentioned before, or provide several options for the practitioners without any explanation.Zhu (1998) pointed out that if test ar used interchangeably, tests must be equi valent. Different tests may involve different muscle groups. According to Pat Manocchias Anatomy of exercise a trainers guide to your mildewout, PU involves biceps brachii,brachioradialis, latissimus dorsi, posterior deltoid, rhomboid, teres major and trapezius. For PSU, it involves deltoideus, coracobrachialis pectoralis major, pectoralis minor and triceps brachii. So a guinea pig may get a in high spirits score in PSU but a low score in PU, because he/she has a very knockout pectoralis major.Sherman Barfield (2006) pointed out that if tests argon not invariable in sorting, problems can occur when using test sores to classify whether the subject are in a health fitness zone.Purpose of StudyThe purpose of the conceive was to examine the interchangeableness as well as the concurrence of categorisation betwixt the upper-body strength and endurance tests, including PU, MPU, FAH, PSU and MPSU by assessing the correlation amidst the test results among them.Significance of S tudyMahar and Rowe (2008) pointed out that for researches, the aims of fitness test are to (a) lay out the association between fitness and other health outcomes, (b) evaluate the specialty of training platforms designed to increase fitness, and (c) determine the prevalence of adequate levels of fitness in define population groups. In school settings, fitness tests are used to (a)provide individualized feedback to students about their fitness levels, (b) make recommendations for increasing or maintaining current fitness levels, (c) educate students about physical activity and fitness , and provide information to help determine the effectiveness of physical fostering programs.Among the test manual of work upss available for selection, there are five commonly used upper-body strength and endurance tests, which are PU, MPU, FAH, PSU, MPSU. Test manuals usually include one of these tests in their test battery without explanation on the selection. Also the test manuals usually dont have any detailed information of the test, such as which muscle group ordain be assessed. FITNESSGRAM, a test manual currently endorsed by AAPERD, allows the practitioner the option of administering any of the quartette upper-body strength and endurance tests, without stating their differences.As fitness test is important for assessing subjects fitness, hence, a subject should receive the same criterion classification regardless of what test is administered. If the tests can be used interchangeably, they must be equivalent. Misclassification of a subject may lead to an overestimation of appropriate physical activity or a discouragement in participation. Therefore, this consume was designed to determine the consistency of classification, and interchangeableness of the five commonly used upper-body strength and endurance tests.Chapter 2 survey OF LITERATUREIn most of the physical fitness test batteries, they include upper-body strength and endurance test, which implied the importan ce of upper-body strength and endurance in physical fitness (AAHPERD, 1988 Chrysler Fund-Amateur Athletic Union CE-AAU, 1987 Institute for Aerobics Research IAR, 1987 PCPFS, 1987).Upper-body strength and endurance are important for performing daily functions and various physical activities. A fitness test can assess subjects physical fitness level and help developing a satisfactory fitness program for the subject. But if the fitness test can not evaluate or classify the subjects physical fitness level accurately, it may lead to over or underestimation of the ability of the subject. The present study was to determine the consistency of classification, and interchangeability of the five commonly used upper-body strength and endurance tests.The come off of literature for the present study focused on the avocation aspects (a) rigourousness and reliable of the five upper-body strength and endurance tests, (b) compare reliability of the tests, (c) compact of literature review.Validi ty and reliable of the five upper-body strength and endurance testsPate, Burgess, Woods, Ross , Baumgartner (1993) study the concurrent and construct validity of three common field tests of upper-body muscular strength and endurance including overstretch, flexed arm hang, push-up, Vermont modified pull-up and New York modified pull-up in children aged 9-10 years. The major findings are that the test performances were importantly associated with measures of weight-relative muscular strength, except push-up test, which was correlated importantly with the criterion measure of secure strength, r(92)= .32, pMcManis, Baumgartner and Wuest (2000) studied the objectivity and stableness reliability of the 90o push-up test for elementary, high school and college-age students. They gave out some recommendations on improving the objectivity and stability reliability of the test, (a) the cadence should not be too slow, (b) elementary students and low-strength college women would be more succ essful in performing push-ups on their knees, (c) subjects should be take to wear tight, short-sleeved shirt for better judgment on angle of elbows. Baumgartner, Oh, Chung and Hales (2002) also suggested that women and very young individuals should execute push ups on the hands and knees. as well as the clothing, they pointed out that hand placement must be specified in the push-up test protocol.Romain and Mahar (2001) firm the test-retest reliability and equivalence reliability of the push-up and the modified pull-up tests from both norm-referenced and criterion-referenced frameworks. Sixty-two students aged between 10.5 and 12.3 years were administered the push-up and modified pull-up tests. The criterion-referenced test-retest reliability estimates were high for both tests, but the equivalence reliability estimates were comfortably lower between them. Also the criterion-referenced equivalence reliability findings were not acceptable.Clemons, Duncan, Blanchard, Gatch, Hollande r and Doucet (2004) determined the relationships between flexed-arm hang and select measures of muscular fitness, which are rank(a) strength (1RM lat pull down), relative strength (1Rm/mass) and muscle endurance (repetitions to ill at 70% of the 1RM). Sixty college-age women were studied and the results showed that FAH is a test of weight-relative muscular strength and appears unrelated to absolute strength or muscle endurance. comparison reliability of the testsPate, Burgess, Woods, Ross, and Baumgartner (1993) found that the performance on the five field tests(pull-up, flexed arm hang, push-up, VMPU and NYMPU tests) were only moderately intercorrelated. The highest interest correlation was between flexed arm hang and VMPU tests, r(92)=.71, PRomain and Hahar (2001) were the pionners to study the criterion-referenced equivalence reliability estimate between push-up and modified pull-up tests among young children. They found that the classification agreement between push-up and mod ified pull-up tests was low. Also they pointed out that because the FITNESSGRAM allowed the physical activity directors to choose among four tests to measure upper-body strength and endurance, the criterion-referenced equivalence reliability of these tests should be examined.Sherman and Barfield (2006) studied the equivalence reliability among the four upper-body strength and endurance tests(Push-up, pull-up, modified pull-up and flexed arm hang) in FITNESSGRAM. 383 children in Grades 3 to 6 were tested over a week. The result showed that the equivalence reliability between PSU and MPU was acceptable for boy, but unaccepted for girls. The classifications for boys aged 10 and 11 regarding the push-up and pull-up tests were not consistent, but they were consistent for girls, except age 11.Summary of literature reviewUpper-body strength and endurance are important for daily functional activities. A valid upper-body strength and endurance can accurately assess and classify subjects mus cular fitness level. This information can help physical educator the develop suitable fitness program for the subject.The above studies shown that the five field test are valid for measuring weight related strength rather than absolute strength and endurance. Also, for the equivalence reliability among the tests, there is lack of study on college student.Definition of TermsThe following terms were defined operationallyHealth-related physical fitnessAccording to American College of Sport Medicine (2003), health-related physical fitness actually has four components aerobic fitness, muscular fitness, flexibility and body com sight. Muscular fitness is the strength and endurance of individuals muscles.Muscular StrengthDocherty (1996) stated that the outside(a) System of Units (SI) defined strength as the maximal force or torque developed by a muscle, or muscle group, during one maximal voluntary action of unlimited duration at a specified velocity of movement.Muscular EnduranceDocherty (1996) defined that muscular endurance is the ability of a muscle, or muscle group, to generate force repeatedly or for an panoptic period of succession. place upAccording to AAHPED (1988), Pull up was defined as a person using round-arm grip, body completely extended, raise until chin clears mensuration, hence lower to wide hang as in starting vista.Flexed arm hangAAHPED (1988) defined Flexed arm hang as a person using overarm grip and in a business office with chin clearing bar, elbows flexed, authority close to bar and hold this position as long as possible.Push upChrysler Fund-Amateur Athletic Union (1987) defined push up as a person in prone position, elbows bent, hands two-dimensional on floor, thumbs pointing inward and next to chest, then pushes body up until elbows are straightened, while heels, hips, shoulders, and head remain in the same straight line. special pull upPate, Ross, Baumgartner (1987)defined it as a person in supine position, the bar adjusted jus t out of reach of fully extended gird. That person grasps bar with overhand grip, maintaining blazonry and legs straight, feet together. Then pull up the body with arms so chin clears the bar.FatigueAccording to pole et al. (2006), fatigue is defined as the decreased capacity to do work and the reduced efficiency of performance that normally follows a period of activity.Research HypothesisAccording to the above literatures reviewed, it was hypothesized that1. There would be no significant correlation between thefive upper-body strength and endurance test results. And the classification is not consistent.Chapter 3METHODThe purpose of the study was to examine the interchangeability as well as the consistent in classification of the upper-body strength and endurance tests, including PU, MPU, FAH, PSU and MPSU by assessing the correlation between the test results among them. This chapter was divided into the following parts (a) subjects (b) procedures (c) method of analysis and (d) s tatistical hypothesis.SubjectsThis study was targeted to male college students, who were studying in Hong Kong Baptist University and aged between 19 to 25 years old. Subjects will be selected by convenient sampling. Before the study, subjects was asked to sign on the bear forms after knowing the purpose, benefits and risks of the study.ProceduresIn this study, subjects were invited to perform the five upper-strength and endurance tests in a specific sequence, which is pull-ups, push-ups, modified pull-ups, modified push-ups and flexed arm hang. Test and retest were held on two separate geezerhood with in a week. All tests will be conducted in the fitness get on of Hong Kong Baptist University or the fitness style of LCSD.The subjects were strongly advised not to have a heavy meal 2 hours before the sit-up tests. The subjects were invited to do tippy up exercises. inviolable up exercises included 5 legal proceeding jogging or make pass and then 5 minutes related stretching exercises. After the warm up exercises, subjects were invited to perform the tests.The description of the pull-ups, push-ups, modified pull-ups and flexed arm hang tests were exposit by the FITNESSGRAM (2007)Pull-upsThe subject should start will hiatus position an the bar with an overhand grasp. The subject uses the arms to pull the body up until the chin is above the bar and then lowers the body again into the full hanging position. The exercise is repeated as many times as possible. There is no time limit.Push-upsThe subject should begin with a prone position with hand place under or meagrely wider than the shoulder, fingers stretched out, legs straight and around apart, and toes tucked under. Then pushes up of the mat with the arms until arms are straight, keeping the kegs and back straight. The subject then lowers the body using the arms until the elbows bend at a 90o angle and the upper arms are parallel to floor. This movement is repeated as many times as possible.Modified pull-upsThe student grasps the bar with an overhand grip. The pull up begins in this down position with arms and legs straight, buttocks off the floor, and only heels tinge the floor. The student then pulls up until the chin is above the bar. The subject then lowers the body to the down position. Movement continues in a rhythmic manner.Flexed section HangThe subject grasps the bar with an overhand grip. With the assistance of one or more spotters, the student raises the body off the floor to a position in which the chin is above the bar, elbows are flexed, and the chest is close to the bar. The position is held as long as possible.Modified Push-upThe subject should begin with a prone position with hand place under or slightly wider than the shoulder, fingers stretched out, legs straight and slightly apart, and knees tucked under. Then pushes up of the mat with the arms until arms are straight, keeping the legs and back straight. The subject then lowers the body using the arms unt il the elbows bend at a 90o angle and the upper arms are parallel to floor. This movement is repeated as many times as possible.There will be three minutes rest between each test.DelimitationsThe following delimitations were included in this studyThe subjects of the study were delimited to the male students who were studying in Hong Kong Baptist University and aged between 19 to 25 years old.All the tests were carried at the fitness room of Hong Kong Baptist University or the fitness room of LCSD.The test and retest were held in separate days within a week.Data digestStatistical hypothesisThe following null hypothesis was examined1. There would be significant correlation between the five upper-body strength and endurance test results. And the classification is consistent.Statistical AnalysisData were reported as mean and standard deviation. Minimum and uttermost values of variables were analyzed by the Statistical Package for Social acquisition (SPSS). Pearson Production Moment C oefficient of Correlation (r) was used to examine the correlation between the 1-min sit-up result with that having fixed frequency and no time limit. An of import level of pLimitationsThe following limitations were included in this study1. The subjects are restricted to the students who can use the fitness room of Hong Kong Baptist University or LCSD.2. The indigence of the subjects in performing the tests, as all the tests are with no time limit, was uncontrollable. It might affect the results of the study.3. The performance of the subjects might be affected because of their physical lifestyle and the physical activity level.4. The performance of the subjects might affected due to their different physical characteristics.Study findings are applicable only to the subjects included in this study.
