Title: The Effects of Whole-Body Vibration on Vertical Jump, Power, Balance, and Agility on Untrained Adults.
The utilization of whole body vibration (WBV) in sports and rehabilitation courses to improve athletic performance, mobility among musculoskeletal deficiencies patients, and boost bone mass and strength has increased in the recent past. It is suggested that WBV could be a useful tool for warm-up before the actual training. Despite this, the existing research is controversial as to whether WBV impacts the height of a vertical jump, power, agility, and balance. Some studies indicate that these variables improve with WBV exposure, others suggest the opposite (Wallmann, et al. 56). A large percentage of the research is based on professional athletes. On the other hand, there is little literature on the acute consequences of WBV on more heterogeneous groups.
The study’s purpose was to assess how WBV acutely impacted vertical jump, agility, power, and balance among untrained male and female adults. It hypothesized that there would be changes in all the four variables after exposure to WBV.
The study involved a total of 36 male and female participants aged 18-40 years. After calculating, their mean age was determined as 24.5 years. The subjects were untrained in the sense that they were not enrolled in any college or university and were not professional athletes (Wallmann, et al. 57). Another criterion used to select the participants is that they had to be good at speaking and understanding English. The study also excluded those who had various characteristics and conditions such as pregnancy, severe osteoporosis, serious heart problems, cancer, orthopedic injuries, thrombosis, and pacemaker. All the respondents signed informed consent before engaging in the assessment.
Given that the study excluded individuals who were in higher learning education institutions, it did not represent the entire population of untrained adults. Being in college or university does not mean that one is an expert in exercise as there are many in those establishments who do not work out. For this reason, the findings of this research were limited to untrained adult persons who had finished college or those who never attended college in the first place.
The researchers successfully controlled the variables and the study’s results were based on no other reasons other than those in the hypothesis. Initially, the participants were briefed on what the study was all about. Nevertheless, the researchers did not disclose to the subjects that the study predicted there would be a change in the variables which were to be tested. This is the first sign of the researcher’s control of the variables. Perhaps, if the participants had been informed that agility, for instance, was supposed to vary after being exposed to WBV, they would have tried to over or underperform or exaggerate the activities they were supposed to engage just to ensure that there was a change.
The subjects were required to attend three sessions. Each session focused on one dependent variable and there was a 48 hours difference between the sessions to ensure that fatigue and other factors that would have influenced the effect of WBW were mitigated. This was also another way that the research effectively controlled the variables. That is, the study made sure that WBV would not affect the dependent variables due to any underlying factors but just it. Also, the participants were given 2-minute rest periods during the session before undergoing WBV. Had they not been allowed to take a break, the effect of WBV on the vertical jump, power, agility, and balance would have been affected by tiredness or fatigue.
The results of the study revealed a huge difference across all the genders on all the dependent variables following WBV exposure. As for the vertical jump height, it improved although with a small range in males but decreased in women. Moreover, the agility and power performance of men was better than that of women after WBV. Nevertheless, the standing balance among the females was better than that of males.
These outcomes of the study are reliable given that they have a justifiable basis. They were based on real-life tests. The researchers had conducted the tests on their own and had the first-hand experience in collecting the information and analyzing it. Nevertheless, the results are not reliable since the sample population used was not an actual representation of untrained individuals.
This research means that we the way in which WBV in relation to training is viewed should change. Based on the results of this study, WBV can enhance various components of athletic performance such as agility and balance when applied acutely (Wallmann, et al. 62). This study has added to the limited literature that exists on the effects of WBV on exercise performance among untrained experts.
This research means that aspects such as balance and ability can improve performance various sports including basketball, football, and hockey among others. As such, individuals who want to engage in these sports who are untrained should consider WBV. Generally, in physical therapy, WBV can be used to enhance agility and balance among individuals with various conditions.
