That was about just this side of Worthless…
Wasn’t your present though…
Well, Marc loved it, I’m sure!

Thanks
I’m afraid true HiT aficionados will ignore any information on cardiovascular conditioning.
After listening to a certain ER doctor recently reiterate how pyruvate stacks up outside the mitochondria for processing inside this organelle , and driving the Kreb cycle which fulfills any needed cardiovascular conditioning needs dampens any desire to discuss cardiovascular fitness.
The truth is somewhere in between. Everyone realizes that resistance training is a poor method to condition the cardiovascular system. Everyone realizes cardiovascular conditioning is rarely used to improve strength. So when an ER doctor (or any other Dr.) raves about a method of resistance training that makes cardiovascular conditioning superfluous, your antennas need to be raised to a level that makes you wary of such claims.
With that said, a recurring issue that fails to get mentioned by cardio detractors is that prolonged muscular contractions compared to locomotive activities used during cardiovascular conditioning will occlude blood flow in the working muscles until the muscles relax. This impedes venous return. However, that said, there is something that needs mentioned, in that recent experience with strong range leg press (perhaps the highest intensity of exercise available), will cause rapid breathing after conclusion of a 30 second set. 1-2 minutes may pass before the resultant rapid breathing returns to normal, thereby indicating there was pyruvate stacked up. Additionally, an oxygen debt is also being reimbursed as blood flow is indeed increased. This however does not result in higher levels of cardiovascular conditioning.
Lifting weights and subsequently performing the Valsalva maneuver can collapse the Superior Vena Cava, as it gets squished by the increase in intrapleural pressure. This greatly reduces venous return and limiting cardiovascular output. If you lift heavy, avoiding Valsalva maneuver is difficult to accomplish.
TIME TO EAT CROW
A certain ER doctor wrote:
“Is it possible, that at very advanced levels, strength and metabolic conditioning will need to be separated? I have poked fun at those who perform interval aerobics such as the Tabata protocol. I feel that such conditioning is easily provided in the context of a proper workout. Maybe a very advanced subject will require a very infrequent strength regimen with such an interval protocol interspersed to preserve metabolic condition. While such thinking is certainly blasphemy to me, I can’t ignore such questions in my own mind unless I want to eat crow in the future.”

Crow is not something I want to eat. Many experts are currently recommending Zone 2 cardio. I think cardiovascular conditioning for health can be had relatively easy. Realizing that for the mitochondria to be operating, oxygen is required at this organelle. Oxygen comes from breathing. If exercise causes excessive breathing rates, then carbohydrates are being utilized such as in the Tabata protocol. But for health, minimal forays past the Ventilatory threshold 1 would be necessary for heart and lung health. Being in the upper 5 percentage of VO2 max levels does not result in longevity. Increasing Ventilatory threshold 1 level results in the body utilizing more fat storage. Where is the interest in this? HiT aficionados are off in fantasy land trying for another 1/4 inch on their biceps.
In the end, talking or writing anything related to cardiovascular conditioning is a huge waste of time. HiTers ain’t interested.
