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 came to JKC through recommendations from my peers from lululemon. As a current ambassador, I’ve been introduced to legacy ambassadors, like Jon, and I knew a bunch of other people from the store were working out here so I wanted to give it a go. I often dread lower body workouts so I started coming here to do legs. I’ve had such great progress that I now come twice a week— and, I no longer hate leg day!

I’ve never experienced this sort of hybrid between group workouts and personalized service. Many group strength training services offer a sort of one-size-fits-all workout for the general population, which has never been of interest to me, because I want my workout tailored to my needs! I LOVE that you can be in a group setting while doing your own personal program; I love the camaraderie and community at JKC, and, I’ve seen incredible results thus far! Jon is always so attuned to what I need.

I recently visited Newfoundland for one month, and was looking for a good place to train while I was there. Jon and the team at JK conditioning really took the time to assess what I already knew, and set achievable goals for the time that I had with them. The gym was such a great place to push yourself. It had everything you needed, but more importantly it had a well organized, very knowledgeable, and really motivating group of trainers to push you at each workout. Not to mention a really nice group of other members who also motivated me to go that little bit further. I would highly recommend the gym to anyone who has a goal and wants to find a place to help them achieve it.

I saw an article in Men’s Journal that quoted Jon in about 2018 while traveling and was impressed that someone in St. John’s made that international magazine. Jon spoke about an exercise called the Farmer’s Walk and I started working that into my routine at the YMCA. I tore that article out of the magazine and kept it, meaning to make contact, but got busy. Then I had lunch with an old friend Bruce Dyke. I hadn’t seen Bruce for a while and I remarked that he looked super healthy and fit. He told me about his, and his son Cas’, experience at JKC and then I remembered the Men’s Journal article! No coincidences!

The experience is unique on many levels – great people, camaraderie, passion, purpose, and dedication. Jon and Thomas are attentive, precise and understanding. Their teaching has unlocked a new perspective for me with what our bodies are capable of. I still appreciate the YMCA, wonderful place, but I can’t imagine working out without Jon and Thomas now.

A few years ago, I pinched a nerve in my neck which led me to be stationary as any form of movement would cause extreme pain. During this time, my fiancé (Sean) started at JKC and loved it!! Once I overcame the nerve issue, Sean spent a long time trying to convince me that JKC is exactly what I needed to safely start working out again (I’m slightly stubborn and was super scared of re-pinching the nerve). Long story short, Sean was right… as much as I hate to admit it!

I never had luck at gyms, if it started to hurt I would call it a day. At JKC that is not an option, as Jon & Thomas will push you to finish the workout, whether you want to or not! Working out in a group setting is also a big benefit of working out at JKC, if you’re not feeling motivated you can simply feed off of someone else’s energetic vibes.
