For workout schedule, any chance you could cover if a longer warmup is needed to make a workout possible to do does it really have much difference between:
1- Lower intensity of workout at the beginning to make workout possible to do
2- extend warmup before workout
With the thinking that if I’m doing a mid volume plan it would be better to go to high volume and do 1 then take the same amount of time doing a mid volume workout with a longer warmup.
see: Sweet spot: first few intervals much harder then last few
After doing most of Sweet Spot Base 1 with outside workouts, I want to continue the outside workouts for Base 2.
For FTP assessment, is it better to do the test outside or would doing the Ramp test indoors be okay? If outside is better, is there a particular test that is better to use. I have the Wahoo Bolt, which has the tests loaded on the unit already, so I was wondering if one of their tests okay to use.
Not sure if this has been covered, I am curious to know how the gut microbiome impacts exercise performance through lactate-propionate metabolism. A recent paper in Nature (1) showed that a certain lactate metabolizing gut microbe increased in runners post-marathon. This microbe increased exercise performance in mice because of increased conversion of lactate to propionate in the gut. Is this the next frontier in performance enhancing substances, e.g. propionate and microbiome dropping? Love the podcast and Trainer Road!
Having finished 2x SSBHV I would say that the first interval was ALWAYS the hardest. Once you get into a rhythm and your head gets over the pain then it all feels much more do-able. Moving from Mid to High in order to get more warm-up I wouldn’t advise, just extend the warm-up.
A couple of interesting reads, esp for those trying to really fine tune carb requirements:
Glycogen is differently distributed within the muscle fibers (subsarcolemmal ~5-15 %, intermyofibrillar ~75 % and intramyofibrillar ~5-15 %).
Moreover, it appears that subsarcolemmal, intermyofibrillar and intramyofibrillar glycogen powers different mechanisms in muscle contractions.
Intramyofibrillar glycogen is preferably depleted during high-intensity exercise and seems to power cross-bridge cycling [aka power stroke]. Moreover, depletion of this form highly correlates well with skeletal muscle fatigue.
…muscle biopsies were obtained both before and after exercise consisting of completion of a approximately 1 h cross country skiing time trial performed by elite skiers. In type I fibres before exercise, glycogen was distributed with 77% in the intermyofibrillar space, 12% in the intramyofibrillar space and 11% in the subsarcolemmal space. After exercise, intramyofibrillar glycogen was reduced by 90% compared to reductions by only 75% in intermyofibrillar glycogen and 83% in subsarcolemmal glycogen
Studies performed from the whole-body to organelle level suggest that the pool of intramyofibrillar glycogen has a key role during repeated contractions…
In the future, it may turn out that exercise training and nutritional strategies that ensure the right amount of glycogen in the right place at the right time are more important to enhance muscle function and performance than simply maximizing muscle glycogen loading.
Hey guys, another great pod last week. Thanks for keeping us all motivated and on track.
I wanted to find out more about something discussed during this episode. @Jonathan talked about combining a mid-volume plan (doing it Mon-Thursday) with a ‘choose your own adventure’ ride on the weekend. How do you go about this in plan builder?
