Running head: CRITICAL EVALUATION OF A HIP EXTENSION EXERCISE JOURNAL ARTICLE Critical Evaluation of a Hip Extension Exercise Journal ArticleNameInstitution
CRITICAL EVALUATION OF A HIP EXTENSION EXERCISE JOURNAL ARTICLE 1Executive summaryThis paper will evaluate a journal article in the field of biomechanics. The chosen article has discussed different types of hip extension exercises to determine whether all of them are made in the same way and if they have the same effects on the body. There are three types of hip extension exercises discussed in the article and they include exercises based on forty- five degrees, ninety degrees, one hundred and eighty degrees. The evaluation will be based on the keyissues discussed in the article, the main motivation which led the researchers to carry out the research, the process they used to carry out the research, the reason behind the research, the findings from the journal, and the conclusion based on the researchers. A discussion of the main issues learned will also be included.
CRITICAL EVALUATION OF A HIP EXTENSION EXERCISE JOURNAL ARTICLE 2Introduction The research contained the journal entitled “Are all hip extension exercises created equal?” was basically designed and carried out to determine whether all the hip exercises produce the same results (Contreras et al., 2013). These exercises are designed to create power and stamina to different people like athletes, footballers and other different people who participate in different games. The exercises are very important because they are one of the factors which determine whether the players will be successful in the career (Steele et al., 2015). They also make the body flexible and adaptable to the environment of the game. This makes it very important to evaluate different types of those exercises scientifically to determine the ones which are good and can produce the best results for the people.Many researchers claim that these exercises may produce the same results given that other factors are kept constant that is the nature of the body, the number of years, the frequency of the exercises and the duration which the person takes to do the exercise (Kendall et al., 2015). However, other researchers claim that even though these exercises may have similar protocols onhow they are carried out, some scientific factors can influence them and hence produce different results. Some of the scientific factors which can lead to different results include the angles at which the exercise are carried out and those angles maybe forty -five degrees, ninety degree and one eighty degrees respectively (Lun et al., 2015). Due to this perceived difference in the hip exercises, that is why the researchers decided to scientifically access if the claims are true that the exercises may produce different results.
CRITICAL EVALUATION OF A HIP EXTENSION EXERCISE JOURNAL ARTICLE 3Methods The researchers used physics methods to evaluate the effects of different types of exercises. They included three types of the exercises and named them as A, B and C respectively. The first exercise which is labeled as A and given the name good morning exercise is carried on at 90 degrees where by the participants lifts weight while standing straight and movement only occurs at the hips. The second exercise which is labeled as B and given the nameback extension exercise is carried on at 90, 180, and 135 degrees but with the person bending over a torso. In this exercise, the person either makes the legs straight that is 90 degrees or bents them at 135 degrees or 180 respectively. The third exercise is labeled as C and called the horizontal back extension exercise. This exercise is also carried out at three levels of degrees that are 90, 180 and 135 respectively. The person here moves the back side only while bending on the torso. There follow the methods of calculating the effects of each exercise. There are many factors and many determinants which are used to calculate the effects. Out of the three exercises, each of them includes a calculation of two moments. The two moments include the moment of the HAT acting on the Hip joint and the second one includes the moment of lb(45kg) external resistance acting on the hip joint (Contreras et al., 2013). The calculations are carried out in different stages whereby the weight of HAT is calculated by multiplying the weight of the participant by 0.68. Then the weight is converted to mass by multiplying it with the gravitationalforce which is 9.8. The external torque of the HAT acting on the hip is then calculated. There follows a calculation of the free torque and then the process is carried out in all the three different types of the exercise.
