The amount of research behind spinal manipulation is growing, however, very little attention has been paid to the possible impacts SM has on athletes – or furthermore strength athletes. The central research question is “What impact does spinal manipulation have on strength athletes?”. The objective of this research question is to guide the exploration and observation of how spinal manipulation impacts the performance of strength athletes. This was achieved via an international research survey. A null and alternative hypothesis was established. Each question was designed to measure how effective SM was on strength performance. There were 5 questions in total that covered the most prominent results in the literature; recovery, technique, R.O.M, pain, strength. Each question required an answer between 1-10, determining how effective the participant felt SM was regarding that specific topic, and each participant’s survey would be submitted out of 50, covering 5 questions worth 1/10 each. 69 participants (n=69; ±0.10 - 10%) enrolled in the research article, 81.2% male, 18.8% female and between the age of 21-55. The null hypothesis was successfully rejected with 95% of the sample population scoring a sample mean value (33.7, 95% CI 31.2 - 36.3) >25 (over 50%), meeting the critical value inclusion criteria of 5% (P = 0.05); concluding it statistically significant with 95% confidence Interval, a 2.6 margin of error and a SD of 10.8. That is a 67% result in favour to SM being effective for strength performance. In conclusion: the data shows that spinal manipulation is an effective treatment to improve overall performance in strength athletes, this includes pain modulation, ROM, technique, strength and recovery improvements.
The decision to explore further research around the effects of spinal manipulation (SM) and on strength athletes is both appropriate and deemed necessary to push forward the body of evidence around this subject. A null and alternative hypothesis was established and the chosen modality of research was approved based on how well that process would align with the purpose of this paper. To effectively collect and display meaningful data an opportunistic sampling process was employed and a cross sectional survey method of study chosen with a single right tailed hypothesis. The survey provided data representing the efficacy of SM for over performance. The results were investigated and analysed to reach a statistical and meaningful conclusion.
Each participant was required to agree to a consent form prior to taking the survey. This was primarily to educate the participant on the study and to ensure they are 18 or above.
The consent form was as follows:
CONSENT, You have been invited to participate in a research study titled “AN INVESTIGATION INTO THE POSSIBLE IMPACTS OF SPINAL MANIPULATION ON STRENGTH ATHLETES”. This study is being done by Brogan Williams as part of his master’s thesis with Selinus University of Science and Literature. The purpose of this study is to explore the possible impacts of spinal manipulation (or chiropractic adjustments) on strength athletes or gym members who train strength. If you agree with the terms and participate in the study you will be asked to complete an online survey/question aire. We require your name, age, gender, and your experience with SM + strength training. Your data will be published in the final research study and master's thesis - your name WILL NOT be disclosed to protect your privacy. By clicking “I agree”, you are indicating that you’re at least 18 years old and have read and understood this consent form, and agree to participate in this research study and have your data used and published
Thank you for your participation.
III. THE HYPOTHESIS
VI. DATA ANALYSIS
Microsoft Excel and OwnSurvey.com was used employing inductive quantitative methods (T-test and P-value). Descriptive statistical analysis was also conducted providing metrics such as the mean, mode, median, minimum, maximum, range, sample variance, skewness, sum, count, standard deviation, confidence intervals, population and sample mean, mean difference and various graphs to make sense of this data.
Overall, athletes are feeling the effects and the positive impacts of SM, and these 5 areas that were chosen to be explored in this study are not only evident throughout the literature but clear to see in the research data of this study. It is important to note, that although extremely useful, SM is no magic bullet and we do require more research on this topic before we can draw hard conclusions . It is also important to mention that although very impressive, many of these effects are temporary and likely not lasting – this isn’t a bad thing however, as there are many ways clinicians and doctors alike can use these short-term adaptations to implement and cement long term healthy adjustments and changes to the system . It is about using SM within the understanding of movement, biomechanics, exercise and rehab to maximize the results you can provide for your patient . Outdated or limited thinking and expectations that SM or chiropractic adjustments can “heal” ailments or disease is outdated and a damaging sentiment for the patient and the progression of modern physical medicine.
