🚨🏋🏻‍♂️PUBLICATIONS The last few months have been very kind, enabling myself and colleagues from all over the 🌍 to collaborate and share a multitude of research projects 📊 #VBT research is coming along nicely! Key points and links to all recent publications within this thread 👇

@Scott_Damman @Scott_Damman - we need to catch up, Scott

Primo example of the MFX Velocity (left) & Force (right) Sequence visuals identifying the higher performing rep. Look at the Blue. AVG V was 0.74 / 0.73 PK V was 1.25 / 1.22 Concentric only data does not distinguish rep quality. Elastic Index 100 was 3.24 / 4.98 (blue)! 👈👍

Pleasure to be involved as always @Steve381

@Scott_Damman @movefactorx @Josh_Inman_ interesting metrics to consider for future studies 👀

From a performance perspective, 2 very different squat reps. Yet, the full ROM - Pk V of 1.4 vs 1.51 & Avg V of 0.87 vs 1.01 - does not tell the story. ⁦@movefactorx⁩ Velocity Sequence™️ does tell the story, big time step forward for the practical minded seeking results.

@christombs71 @RICH_AgilityLab @Steve381 @JonathonWeakle1 @DrChrisBishop @OutputSports @GymAware @Scott_Damman - might be worth getting involved in this one. From all my chats with Scott he’s always been a big advocate of looking [far] beyond traditional MCV and instead to ECC and further derivatives. Certainly an area needing more research 🔬

@RICH_AgilityLab Historically concentric only.. it would be great to hear the researchers views on ecc data collection in this area. Device capability may be the limiting factor at this point. @Steve381 @HarryDorrell @JonathonWeakle1 @DrChrisBishop @OutputSports @GymAware

Anyone have any insight into ECC overload velocity zones and their force outputs? We've got well researched VBT zones for concentric, but cant find anything for eccentric....

@Steve381 @christombs71 @balsalobrephd @JonathonWeakle1 @BanyardHarry @IrineuLoturco Steve knows! Get a little multi-site collection up and running and we could have a mass of data across a range of unilateral movements in no time.

@christombs71 @balsalobrephd @JonathonWeakle1 @HarryDorrell @BanyardHarry @IrineuLoturco I’m sure we could get a research project together pretty easily, right @balsalobrephd @HarryDorrell @BanyardHarry ?

We need more research for the SL variations integrating VBT @JonathonWeakle1 @Steve381 @HarryDorrell @BanyardHarry @balsalobrephd @IrineuLoturco

@christombs71 🙌🏼

Lessons learned from 4 weeks on the road, presenting and problem solving integrating VBT to improve the training process, and coaching.

@Joe_Eisenmann @HowellsDan @Joe_Eisenmann - this is an incredible take on a CV and something I will be creating for myself and sharing with my students 🙌🏼

@HowellsDan Google 'cv infographic' - see images and articles - one-stop shop; had several + comments on it

Those hiring, when they do actually go through a correct hiring process only skim read your CV/Resume A first impression is made in the first 5-7secs… Yet so many people aren’t asking for a critique of their CV This last week I spent time with two coaches asking me why I thought they werent getting interviews Networking and experience aside, it’ll likely be the impression you (don’t) make from you CV Send it to someone you trust. You’ll be surprised what they see that you don’t… If you want my tips on CV writing for sports jobs, comment “CV” below, and ill DM It you

Nice to receive this today from the @IUSCA 🏋🏻 #StrengthAndConditioning

@anthonyturneruk @MDX_LSI @MiddlesexUni Very deserved mate. Celebratory beers in Vegas incoming 👀

So proud to have made Professor. I’m incredibly grateful to the @MDX_LSI staff and @MiddlesexUni, along with the many other academics, coaches, and athletes that made this possible - thank you 😱🙏🍾

@Scott_Damman Complete agree with you here @Scott_Damman - lots of devices now available, so make sure you’re picking the one that meets your / your squads requirements and can be seamlessly integrated (another often overlooked factor). Will you be at the @NSCA Nat Con in July?

With the pending retirement of the PUSH product, teams are looking to replace their VBT tech. Take a breath and examine the What/Why/Purpose with your program's VBT application - this is a dead ass serious point that I still believe most mainstream users completely miss.

We are delighted that 84% of the School's research was classified as 'world-leading' or 'internationally excellent' in the Research Excellence Framework results released today. Thank you to all from the School and wider university who contribute to/support our research. #REF2021

📢The formally known PESP research group is back in Twitter action... 🚨 New name 🚨 New look 🚨 New members 👀 Keep your eyes peeled for some updates on what our team have been up to! @LincolnSportEx @UoL_CSS

Pleased to announce that the BSc (Hons) Strength and Conditioning in Sport is now endorsed by The Chartered Institute for the Management of Sport and Physical Activity (CIMSPA) @LincolnSportEx @UoL_CSS @unilincoln

@VBTcoach Thanks for sharing @VBTcoach - if anyone has any questions then fire away. Link to full text: researchgate.net/publication/34…

More great research from @HarryDorrell group VBT protocols vs customised to the individual. Both made pretty good progress, but if it’s available to you individualisation is the way to go. Something we are looking to integrate into the metric app as we build.

@RiccardoRambo @VBTcoach It’s important to note, they only received an audio cue from the GymAware - nothing else. That’s the only difference, and really is the whole point of the study. “VBT” facilitates the additional feedback that other training methods don’t offer.

@VBTcoach And also there is the “bias” problem.

Can % training still be considered appropriate for strength? Dorrell et al, 6-weeks training, VBT group outperformed %BT group across the board. ⁠PLUS: VBT saw a 4x greater improvement in jump height (2cm v 0.5cm) With less work done on all lifts #strengthandconditioning

@RiccardoRambo @VBTcoach Happy to answer any questions @RiccardoRambo. For clarity, all athletes received the same instruction prior to lifting, and all athletes received the same encouragement during lifting - only the VBT group received an audio cue (bing) if they hit or missed the target velocity 1/2

@Scott_Damman Thanks @Scott_Damman - if anyone has any specific questions, fire away and I’ll do my best to answer

Harry help us! @HarryDorrell More are adding VBT sport tech but mainstream application stuck in the decades old zones. It's astounding how many are making the $$$ tech investment but entrenched within flawed methodology.🤯 Here's a link to the publication: pubmed.ncbi.nlm.nih.gov/30946276/

@jmc3147 @VBTcoach So the VBT “zones” were specific to that training group - none of the manufacturer velocity based zones you see were used as these were deemed too wide and too general. We essentially created our own “zones” based off the training groups LVP

@VBTcoach We’re the Velocity Zones used as their prescription? For example, 0.75-1.0 m/s for the bar. Or was that based on Velocity Loss?
