@timkettenring Yea. In-game speed is a pretty interesting and misunderstood metric

In-game speed is an interesting metric. Faster isn’t always better

In these murky times of conference realignment for @WSUCougarFB I thought it was important to share my thoughts about what makes all this so sad and where WSU would fit best moving forward. Full episode of @TalkinCougars presented by @FlatstickPub here: youtu.be/7vH_K-1EKJ8?fe…

Dallas Cowboys Camp Day 1 Year 7 with @brandincooks

@timkettenring Yes!

Thank you @BryantFerate for the opportunity to come on the podcast! open.spotify.com/episode/7eqBmg…

@okatc_scott @pbasilstrength Happy to connect and share what I’ve been working on, if you’re interested!

@pbasilstrength I am seeking a 'conditioning test' that is sensitive to fitness, specific to sport (based on demands of competition) with specificity to positions within sport...say, football, for example. Anyone? Thanks!

If you run a conditioning test for "accountability" Then do nothing with the results You just broadcasted to your team that you're full of crap and your standards don't matter They called your bluff

Here’s what’s happening on a rep to rep basis during a RSA test. Two takeaways: ☝️Research has shown as we get deeper into RSA protocols the aerobic system becomes a more relevant player in energy production. ✌️The aerobic system is the main driver in between rep recovery.

Had a great day at @oregonfootball SNL camp, fastest guy there running 4.43 40 yard dash and 22.7 mph on catapult!!! Excited to get back down to Eugene soon!! @CoachDanLanning @Coach_CHampton @_CoachBoyd @CoachJoeLorig @BrandonHuffman @eforcefootball @westlinn_fb

@Gareth_Sandford I’ve recently starts Speed Capacity Builder Testing & Consulting (SCB). An organization focused on providing team sport conditioning solutions to increase performance, resilience & success

@EJStrength Thanks Erik. What are you working on?

A greater capacity to perform repeated high intensity efforts off short rest (<10s), Differentiates higher performing teams in semi-pro rugby league. But what qualities underpin repeated sprint performance?

Three main factors that affect RSA: ⚫️Sprinting Ability - how fast an athlete is ⚫️Sprint Energy Production - what energy systems are contributing to the outputs ⚫️Between Sprint Recovery - how quickly an athlete can recover before the next effort

RSA stands for Repeated Sprint Ability and is described as an athlete’s ability to execute multiple high intensity sprints with incomplete recovery. More specifically, in sport, we’re typically talking about: Sprints <6sec Recovery <60sec erikjernstrom1.wixsite.com

#Cowboys wide receiver Brandin Cooks continues to work hard before his 10th year and first season in Dallas 🏈 @Simi_Fehoko says his work ethic is unmatched, and you get a little taste of it here in this video 🔥 (🎥: @ eforceperformance on IG created by undefeatedfilms)

I wanted to share one model I’ve used with my College/NFL groups with great success. There are 3 goals for this training block: 1. Prepare for the expected camp volumes 2. Build a reverse of fitness in prep for camp 3.Minimize residual fatigue while still respecting ACWR
