The Strength & Conditioning Research Rundown February 2020

By Thomas King, MSc, CSCS, CEP

After the positive reception to part one of this blog post, we thought it would be a good idea to introduce part two. Below you will find some good information in a rapid-fire format. Without further ado, let’s get started!

Stay Out Late? Lift Less.

Ever tried to workout hard the day after a late night of partying? Probably wasn’t a fun experience, was it? Thanks to a research team from Brazil, we now know that this isn’t a good idea. In their experiment, participants were given alcohol and forced to stay up late. Lo and behold, when they were tested the next morning, their performance suffered! [1] So, if you still want to workout the day after a big night, try to keep it light.

They See Me Rollin’

Have you ever been foam rolling and wondered how much pressure you should be applying? I know I have. Well, it turns out, to help increase your range of motion (RoM) it really doesn’t matter. A research team right here in St. John’s examined three different levels of applied roller force and found neither one to be better than the other. Who would have thought? So, maybe don’t worry too much about going hard with the foam roller and just do it. [2]

Play Late, Sleep Poorly

To all those reading this, if you play a game of your favourite sport at night, how would you rate your sleep quality that night? For me, it takes a long time to unwind for bed after being highly stimulated for an extended period. It turns out; even professionals are affected by evening games. In a study of professional soccer players, 90% of those who played in games starting after 6:00pm reported sleep disturbances. So, if you are hoping for a good night’s rest, maybe rethink that 10pm hockey game. [3]

Is It The Shoes?

When it comes to deadlifting, what do you prefer shoes or no shoes? Personally I prefer a nice flat shoe with a minimal heel. Well, it turns out that it may not even matter. In a study examining shod (with shoes) versus barefoot deadlifting, researchers from Australia found that there was no difference in rate of force development or peak vertical force between the two conditions. [4]

Better Grip, Better Golf?

Looking for a quick way to improve your golf performance? Researchers from the United States may have just what you are interested in. They tested the effects of training using fat gripz (a rubber attachment that increases the diameter of a barbell) on ball speed, driving distance, and driving carry. Interestingly, training with fat gripz increased these parameters significantly more than a group who did not train with fat gripz. [5]

That’s a wrap! I hope you enjoyed this look at some of the research coming from the strength and conditioning world. As before, if any of this piqued your interest, I have included the links to the studies cited in the article below.

Personal Strength Training by Jon-Erik Kawamoto

I’m 35 and I started at JKC in November of 2019. I was coming off the win of the Royal St. John’s Regatta in 2019, and our crew was chomping at the bit to be stronger and faster for 2020. The reputation of JKC leached into our group and away we went! Unfortunately the regatta was cancelled due to COVID-19, but I just loved JKC so much I stuck around. JKC is different from other gyms because the level of experience the team has is unparalleled. Jon, Thomas and Craig all mesh well together and mentor me in a way that I know they love what they do and are genuinely excited to guide me towards my goals (and beyond). I really enjoy the atmosphere, the sense of community and all the positive vibes that I experience in every session. There’s never a time I don’t want to go because I’m motivated by the team’s coaching style and I get results.

Personal Strength Training by Thomas King

I joined JKC because I wanted to better care for my physical health, but didn’t really know how, or where, to begin. Seeking help from a trainer seemed like a wise choice, and I had heard great things about the staff at JKC. Anyone who knows me knows that I hate exercising. So, I’ve only ever tried sticking with a gym routine twice in my life. Each experience consisted of me wandering around, not knowing what to do, and settling for an elliptical machine or something else that seemed comfortable and non-threatening. Each session was the same, and I felt like I was wasting my time.

Each session at JKC, however, is specifically crafted for me. I don’t have to think about what to do, because I’m told what to do. I don’t have to worry about how to do things properly, because I’m shown (sometimes multiple times!) how to accomplish each task. I don’t have to be concerned about slipping into a comfortable routine, because Jon and Thomas won’t let that happen.

I chose JKC because I row/coach teams in the St. John’s Regatta and was looking to add strength training to our program. My wife is also running friends with Julia, so I got to meet Jon a few times and heard lots of good things. I like JKC over other gyms because of the level coaching I receive and the gym atmosphere. The energy in the gym helps me through the tough workouts.

Not having much if any experience with professional gyms I though it would be along the lines of going to a facility and doing your own thing, getting some instructions from time to time, if you asked for it, and for most part working out on your own, in a large impersonalized setting. I was a bit apprehensive as I figured I’d be standing around a lot looking at all this equipment wondering what to do with it, or worst doing something to hurt myself. Well I couldn’t have been more wrong. Both Jon and Thomas are very attentive, professional trainers, who lay-out an exercise program, from start to finish, for you. They demonstrate the exercise they want you to do and then watch you do it to make sure you got it right. Jon and Thomas are very thorough, patience and non-assuming.

I had spent a fair bit of time in gyms in my teens and twenties but I turned away from the gym to focus on activities that I enjoyed more. What keeps me at JKC is that I do really enjoy it. I always feel that I’ve accomplished something when I leave at the end of my workout. The environment is really positive and focused on challenging yourself whatever your level of comfort and fitness. I’ve also seen results that I’m really happy with; having someone who really knows what they’re talking about to guide your workouts makes them way more effective and focused than just “going to the gym”.

Shortly after I started at JKC, I sustained a fairly major injury that took me off my feet for several months. When I started to get back to activity, it was very difficult. Jon and Thomas worked hard to tailor my workouts to my goals and what I could do. With their help, I’ve been steadily building back strength and function.
