Putting Bands to the “Test”
Whew! That’s the best way to describe what I’m feeling after completing my doctorate after two grueling years of research and 97 rewrites of my dissertation (OK, it seemed liked 97). When I started my doctorate program (being an educator), I was definitely the “odd person” among my classmates, sitting in classes with principals, administrators, and even a few superintendents. After doing most of the understudy program, it was time to focus on the dreaded dissertation topic. After hearing most of the topics, I began to panic and even thought (to myself and aloud), “What the heck am I doing here?” You see, all these former classroom teachers and administrators’ dissertation topics focused on their past or present experience in and out of the classrooms dealing with test scores and how “this” or “that” had an impact on the students or certain ethnicities or gender. Man! I was freaking out! Here I was a strength coach at the high school level and I had nothing even close to what my classmates were submitting. The deadline was very close as well. So I prayed and asked that the Big Man show me what I knew was right there in front of me. Then bam—it hit me! Why not do my dissertation on the effects of something I love and know a little something about—strength and conditioning?
So I gathered up the nerve and my paperwork and met with my committee chairperson. My proposal was titled “An Evaluation of the Use of Bands as a Form of Resistance for Traditional Squats with High School Students.” Before I knew it, my topic was accepted, and I started the next year and a half gathering information and completing research for what I felt was a very informative project for myself and others. I hope I didn’t lose you with all the “introduction” babble, but I wanted to stress the fact that I considered it a huge honor and privilege to be able to complete my doctorate by successfully defending a research study that focused on strength and conditioning.
OK, the facts: I set out to prove that utilizing commercial bands, specifically the light band and the mini band, would increase the mean average of post-test 1RM squats and post-test vertical jumps. There is so much information I should include, but I hate to bore you that much more, so I’ll try to stick to the basics of the study.
The following is a brief overview of the “meat and potatoes” of the study:
Purpose of the study
The purpose of this study is to determine if implementing bands as a form of resistance might be more effective in obtaining both aspects of absolute strength (1RM squat max) and speed strength (vertical jump) for high school students. By implanting bands as a form of resistance to a formatted strength and conditioning class on the high school level, the average mean increase in the 1RM squat max and vertical jump may be higher than that of the control group. The objective is to consistently increase the mean average of explosion capability (vertical jump) as well as absolute strength (1RM squat max) and to transfer these gains to whatever sport the athlete is participating in.
Background of the problem
Over the last twenty years, the focus of strength and conditioning has been on productivity of the lower body, more specifically concentrating on manipulating the squat and bench exercises with velocity and intensity based on a 1RM squat. The quest for not only the strongest athlete but also the fastest or most explosive athlete has been the focus of a majority of strength and conditioning programs on all levels (Baker 2001).
Athletes do not have an abundance of time to recruit what strength levels they do possess. It has been shown that 0.3–0.4 seconds or more are required to reach maximum force levels in an athletic movement (Dermody 2003). Further, during near maximal lifts in the traditional squat and deadlift movements, 0.6 seconds elapse before the movement is completed. The actual time available to produce force in athletics is much less. For example, in explosive movements, such as running or jumping, force has to be produced in less than 0.3 seconds (Dermody 2003). In fact, the requirement is usually closer to 0.1–0.2 seconds. It is crucial for the athlete to be able to recruit as many motor neurons and muscle fibers as possible in the shortest period of time (Dermody 2003).
Method
There are 121 students enrolled in a physical education elective course on strength and conditioning. This number represents a total of four classes offered throughout the instructional day and is optional for the students at JHS. From the 121 students participating in the study, two groups were randomly selected to form both the control group and the experimental group. Both the experimental and control groups bring the total number of students to sixty for the treatment group and sixty-one for the control group. Of the total 121 participants, the majority of students were male (85 percent). Fifteen percent were female.
Once the pre-tests have been completed, the Excel spreadsheets will be updated with student pre-test information and formatted to provide the conjugate method workout. Both groups performed the exact same lifts with the same percentages and supplemental lifts assigned to each student, regardless of which group they were in. Both groups had students throughout all four classes. This meant that each class had a different percentage of each group assigned to each class. The treatment group implemented the use of bands at the beginning of the tenth week of actual lifting. The implementation of the bands was incorporated on the day assigned for dynamic/speed squats (Thursday) and on the days assigned for best effort heavy squats (Monday). At the end of the second, eight-week period, which was the last week of the semester, the students performed the exact same testing procedures. Each student was tested in the squat, bench, power clean, and trap bar as well as the vertical and broad jump. The exact same procedure remained intact with each testing period, ensuring validity in testing results for the data analysis phase. The treatment group had their vertical and squat test averaged to give a mean for the group. The control group underwent the exact same procedure for vertical and squat results to formulate a mean average for both groups in the vertical and squats measured and compared.
Results
Now, I would be telling a “tall tale” to say that all of my research questions proved to be correct. One must take into sincere consideration the analysis program that the data went through. It was submitted to a statistical analysis in social science program, which is a “turbo charged version of Excel that provides every imagined statistic one might need.” But when looking at the results from the perspective of a strength coach or a coach looking to implement bands as a form of resistance, you can’t go wrong. When I ran the stats through the basic Excel spreadsheet, the results speak for themselves, which is what we as coaches are looking for—the bottom line. “Does it work?” From the excerpt below, you will observe that the starting mean average for the treatment group was higher for both the squat and vertical jump, which we all know makes it more difficult to make the gains that ultimately proved the bands definitely had a major impact. The post-test mean averages might not appear to add up, but keep in mind that I have excluded all the participants and just included the outcome. Also, please take into consideration that the numbers don’t signify those that didn’t test due to injury or different issues that had a bearing on the outcome.
In closing, in my dissertation, I did make future recommendations for a longer study period, which translates to using the bands for longer periods of time, preferably in the off-season and pre-season.
I hope that you will see this information useful in some remote way. As I stated, I apologize for the novel, but with this magnitude of study and the format to which I had to follow, I felt it was imperative to include a brief summary of the phases and formats for the study. I know we have all used bands to some degree with our athletes (some more than others), but I wanted to show on paper and in an actual study, not observed speculation, that the bands are a tremendous training tool for any sport. Stay strong and God bless all who work with our young student athletes and assist them in becoming outstanding young men and women.












This is a great article. But we have no idea what exercises were used, and if the bands were looped on the top or bottom of the rack. By “same percentages” I’m assuming the Treatment Group used the same “raw” percentage as the control group, plus any added weight from the bands. Am I correct? Also would be interested to see the entire study. Was this submitted to a journal to be published?
It’s a very interesting article, but I’m with Ryan: Since they’re beginners I’m not interested in the peak force, velocity, or power, but depending if the bands substituted a load or were introduced during a separate session, the results could mean a dynamic, accommodating load might have a benefit over a static, straight load even to non-powerlifting beginners…
After all, generalizing accommodating resistance as superior to a straight load could mean I need to buy me some stocks in rubber
I realize that this isn’t a forum for scientific peer-review, but as a trained statistician and epidemiologist I’m very attuned to issues of study design and associated statistical analysis. I’d be interested in knowing what kind of statistical analysis you did? Running these kinds of numbers through excel won’t allow to you make any conclusions. If the statistics are done properly they don’t lie. However, just looking at the numbers can create a situation whereby you “see what you want to see”. What appears to be a inch increase in vertical over the study is clearly confounded here by the 10 pound differential at baseline among other issues that you didn’t address such as “treatment adherence”. I agree that the results are compelling and by no means am trying to be a detractor to the use of bands in strength development. I think they are a fantastic tool and have been shown to be very effective in the strength training community time and again. However, if you are going to present results like this be careful not to make conclusions on numbers without mention of the proper statistics it can be terribly misleading. That being said, if these methods are going to become more mainstream and adopted by more high schools and the public, research along these lines is absolutely necessary.
Dan,
If I wanted a copy of the full study, where would I go about getting it?
I am assuming that the article has not been published in a journal yet because of how long that process usually takes…but once it is published, it would great to include a link so that the we can check out the full study. This is awesome stuff since a lot of people are beginning to use bands and accommodating resistance, but there isn’t much “scientific” research proving their benefits, even though anyone who has used them can clearly see that it works. Curious as to how you set up the protocols and even the percentage of 1RM used in the dynamic/speed days. A follow up post would be awesome! thanks for the info though!
Would you be willing to provide the full text of the dissertation and/or the raw data?
How were the “Gain” numbers calculated, because they aren’t the (post-pre) ?
Prett cool study because it uses training very similar to what we all use. It would be interesting in future studies to include plyometric/jump training to see if bands provide further benefit over just resistance training and plyo training.
What were your p values for these groups? I can’t tell from your article whether they were omitted for clarity, or because they failed to meet a reasonable standard of significance.
As others mentioned above, it would be great to have a link to the entire study when published. I’m using elastic bands as part of an exercise protocol for my masters thesis and would very interested in the statistical analysis portion of the study as well as how the bands were attached to the bar, etc. I realize you probably left out some details due to space limitations and meaningfulness to a broad audience. Given the relatively large number of particpants for a strength-related study, your outcome validity should be quite high if the statistical analysis is performed correctly. Look forward to hearing more about your results. Congrats on the dissertation!
You said above that the testing protocol was “the squat, bench, power clean, and trap bar as well as the vertical and broad jump,” What did you do with the trap bar? For some reason, the particular exercise you used was not there. A trap bar deadlift?
Also, I’m sure for the sake of brevity in this article you didn’t include it, but for the purposes of your dissertation’s analysis, did you determine that the two groups weren’t significantly different on the pre-test measures. Or if significantly different, did you control for that in analyzing your results?
As others have said congratulations on the dissertation! (I know, mine is pretty fresh in my mind too).
Awesom for the students in the treatment group!Congradulations on your great dissertation.Gotta Love those bands…
I have often thought the same thing that your study shows. However liked stated above I would like to know the setup of the bands, difference in any scheme from test group to control group and also the level of the subjects of the test. As we all can agree on there can be a big difference in a freshman and senior lifting wise. There for the results may vary greatly. I am sure all of this info is in your full study and as said above would love to see the full text at some time.
