September Research Round-Up: Rest Period Edition

Every month, Chris and I write the Strength and Conditioning Research review service. In this article, Chris has written a short preview of the September edition, which comes out in a few days and covers some fascinating new research into rest period duration.


Does rest period duration affect gains in strength during pre-exhaustion training?

The study: The effects of pre-exhaustion, exercise order, and rest intervals in a full-body resistance training intervention, by Fisher, Carlson, Steele, and Smith, in Applied Physiology: Nutrition and Metabolism, 2014 In, this study, my friend James Fisher led a team of researchers to investigate the effects of pre-exhaustion training, which has probably never been studied in a long-term trial before. Although this study is getting a lot of press already for its exploration of pre-exhaustion training, it might escape some people that the researchers actually also looked at rest period duration as well. There were 3 training groups: (1) pre-exhaustion training (single-joint exercises prior to multi-joint exercises) with as little rest as possible, (2) pre-exhaustion training (single-joint exercises prior to multi-joint exercises) with 60-second rest periods, (3) the same exercises in the reverse order (multi-joint exercises prior to single-joint exercises) with 60-second rest periods. By comparing the first two groups, we can see the long-term effects on strength gains of very short and short-to-moderate (60 seconds) inter-set rest period duration. In fact, there was no difference in strength gains in respect of the gains in any of the exercises. Whether different results would have been observed if another group had used an even-longer rest period, however, is unclear.

Who Are the Experts?

I sometimes find it amusing when I receive questions from my readers and I can tell that they assume that I’m an expert an all things musculoskeletal related. Now, due to the fact that I scour through up to 100 journals per month in fulfillment of my responsibilities for Strength & Conditioning Research I do consider myself to be a bit of a renaissance man in the fitness field. However, delving into the research like this teaches you just how clueless you are with regards to many aspects of strength training and conditioning, biomechanics, anatomy, physiology, physical therapy, and research methods.

How to Get the Bar Into Proper Position During Hip Thrusts

On my Instagram page, I’ve been receiving a lot of questions from women asking how to get the bar into proper position during the hip thrust. I therefore decided to film a quick video on the topic, detailing the various methods. The video shows:

  • How to get the bar into proper position when using > 135 lbs (easy)
  • How to get the bar into proper position with bumper plates (easy)
  • How to get the bar into proper position with smaller plates (complicated, but doable)
  • How to get into proper position with a tall bench (complicated, but doable)
