Our systematic review and meta-analysis exploring the effects of caffeinated chewing gum on muscle strength, endurance and jump performance has just been accepted for publication in @JSCRonline
Cheers to @Jozo_Grgic for a great collab!
Key findings and practical takeaways:
Our new systematic review and meta-regression exploring the relationship between training load and muscle fiber hypertrophy has just been pre-printed. Kudos to @StianLa07849895 and @Jozo_Grgic for awesome collaboration!

New from our group: The first study to investigate hypertrophy in isometric actions vs dynamic actions in an ecologically valid manner in trained lifters. When performed at long muscle lengths, isometric had similar (or better) effects on quad growth💪 cdnsciencepub.com/doi/10.113…
We're recruiting participants for our study exploring the effects of isometrics at long muscle lengths vs. full range of motion on hypertrophy. If you're in or near Zagreb and would like to participate or know someone who, shoot me a DM or apply here

Our meta on the effects of muscle length on regional muscle hypertrophy was just pre-printed. Happy to see this finally out and we welcome any feedback pre-review!

@BradSchoenfeld @JamesSteeleII @MiloWolf12 @Jozo_Grgic and my supervisor, Pavle Mikulic.
As of writing this, only 12 studies were conducted on the topic which leaves a ton of work to be done, and we hope that our suggestions for future research on the topic will be helpful for generating ideas.
Important to note that effect sizes presented in the paper reflect the estimated impact of a mean muscle length difference of ~50% (i.e., the difference between 25% and 75%).
A unique approach we took was presenting several models with different priors as @JamesSteeleII held far more skeptical belief's about potential effects of different muscle lengths. This will allow readers to interpret the findings based on...well, their own priors ;)
For our pre-registered model estimates of effects were slightly greater at distal sites (SMD: 0.2), probability of finding a meaningful positive effect and the pooled effects were smaller (50.70-69.78%; SMD: 0.10-0.15) for both mid-belly and proximal sites
I've been invited on the School of Muscle podcast to discuss our findings from a recent MA on the effects of caffeine on jumping performance in females. Tried to give some cool practical takeaways pertaining to RT as well. :) youtu.be/CRPD53OOQ74
Our systematic review and meta-analyis on moderators of caffeine's effects on jumping performance in females was officialy published in the Journal of the American Nutrition Association
Kudos to @Jozo_Grgic for awesome collab once again! :)

2/3 In a subgroup analysis for phase of the menstrual cycle, the ergogenic effects of caffeine on jumping performance were the largest in the follicular phase, possibly due to caffeine attenuating the drop in volintary activation.
1/3 We found a small but very precise ergogenic effect of caffeine on vertical jumping performance in females. Similar effect sizes to the ones found in other types of activities examining caffeine's effects.
Great to see our original paper on ergogenic effects of sodium bicarbonate on resistance exercise published online in @JSCRonline ahead of final publication! 💪

Our meta-analysis (with @jacksonfyfe, @dlhamilton82, Eric Helms, and @EricTrexler) on the influence of RT proximity-to-failure on muscle hypertrophy is now online and Open Access.

Stoked to have our study accepted in JSCR. We investigated the effects of sodium bicarbonate on quantity and quality parameters in resistance training exercise. Interesting findings. Shout out to @Jozo_Grgic and @BradSchoenfeld for the collaboration! 💪
I've just released my first debut single!
