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.

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
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

#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 🔥

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
Properly designed conditioning programs can have a host of benefits! While it’s not the most sexy/exciting aspect of training, it also shouldn’t be an afterthought.
The same attention/passion given to programing speed, power & strength… should be given to conditioning as well!
FREE presentation now available!
In this short video I cover why I believe conditioning is so important, the benefits of proper conditioning, energy systems, annual planning and more.
