My First Published Work

A few days ago, I received a pleasant surprise in the mail.  It was my research I performed a few years ago in graduate school.  After three years and countless hours of work, my thesis was published for reference at Bridgewater State College in Bridgewater, MA.  My publication, isn't by any means a best selling novel with numerous copies in circulation.  In fact, there are only 11 copies you can presently get your hands on.  Nevertheless, I am extremely proud of my accomplishment.

Those of you who have experience conducting research will understand why I am filled with jubilation.  The lab hours, the regulations, the statistics, the DRAFTS..... the list goes on and on.  It tests you physically and mentally, almost to the point of retirement.  During your journey you grow tired of the topic at hand but you persevere in hopes of a successful completion.  I have to be honest, I felt discouraged more than a few times!  When my published copy arrived, I flipped the pages and laughed a bit recalling how one graph took me 4 hours to complete.  Until the day my work arrived, i didn't realize the multitude of what I did.  A few years ago it was only a thought but now it's a reality. 

I plan to submit my work to a number of research publications.  Before I do so, I want to express my appreciation to my readers for their continued feedback and support.  Below is the abstract which describes in a nut shell my research topic.  I am releasing it to you first because you possess the same eagerness to learn as myself.  I know this because you wouldn't be reading my content otherwise.  My gift to you for striving to excel on every level.  

         Acute Strength Responses to Variable Resistance Training:                                       

A Muscular Strength Comparison Between Traditional Barbell and Plate Loaded/Chain 

Resistance Squatting Movements. 



            This study examined the strength improvements of subjects who utilized two different bilateral squat modalities, a combination of chain and free weight resistance and plate-loaded weight only.  Twelve adults (24.5+ 2.5 yrs.) with previous resistance training experience (8.6 + 2.1 yrs.) were selected from the undergraduate and graduate student population at Bridgewater State College (Bridgewater, MA). Subjects were randomly placed in either a control group (n=6) or experimental group (n=6).  While squatting during training sessions, the control group was instructed to only use plate-loaded resistance (PLR). The experimental group was instructed to train with a combination of chain variable resistance (CVR) and plate loaded resistance (PLR). During pre and post-test data collection, each subject’s squat strength was assessed by utilizing a 3RM protocol.   By using a standard percentage chart, each subject’s 3 RM was used to obtain an estimated 1 RM squat.  In order to track the strength improvements amongst each research group, data collection was done before and after the eight weeks of training.

            During the eight weeks of training, both groups trained two times per week (Monday and Friday).  The workouts for both groups consisted of the same exercises, intensities and volumes throughout the entire study. The only significant difference between the workouts was that the experimental group (n=6) trained with CVR when squatting during each training session.

            After analysis was complete, both groups displayed an increase in 1 RM squat strength. The control group (n=6) had an average pre-test squat (r =150 lbs.) of 317 + 16 lbs. and an average post-test squat (r =170 lbs.) of 352 + 18 lbs.  The experimental group obtained an average pre-test squat (r = 280 lbs.) of 371 + 19 lbs. and an average post-test squat (r =230 lbs.) of 418 + 21 lbs. After the training program was complete, the control group displayed an average percent gain of 10.7 % + 3.  The experimental group had an average percent gain of 14.7 % + 3. Therefore, within error bars, training with CVR and PL (Experimental Group) did not result in any significantly different strength gains in comparison to the strength gains of the control group (PLR). 

            However, the data displays that both methods increase muscular strength over eight weeks.  Due to the sample sizes used, our ability to determine differences between each training method was hindered.  To truly determine if there is a difference in strength improvement between the two modalities, further research is needed which utilizes larger sample sizes and clustered subject groups.

I hope you enjoyed the abstract.  If you would like to read the rest of my publication, send me an email at expressing your interest.  Once hearing from you, I will be happy to send you a PDF copy.

Yours in Performance,
