None of the papers you cited show any sort of negative or inverse correlation between Arterial Stiffness and Ascorbate Supplementation.

 

 

Here is one that does (FMD and blood pressure are measures of arterial stiffness):

Oral antioxidants and cardiovascular health in the exercise-trained and untrained elderly: a radically different outcome.

Abstract

Both antioxidant supplementation and exercise training have been identified as interventions which may reduce oxidative stress and thus improve cardiovascular health, but the interaction of these interventions on arterial BP (blood pressure) and vascular function has not been studied in older humans. Thus in six older (71+/-2 years) mildly hypertensive men, arterial BP was evaluated non-invasively at rest and during small muscle mass (knee-extensor) exercise with and without a pharmacological dose of oral antioxidants (vitamins C and E, and alpha-lipoic acid). 

 

 

Confounded by concomitant administration of  E and alpha-lipoic acid

 

The literature is quite clear -- from the studies I posted earlier in this thread that Ascorbate reduces AS, and also improves vascular endothelial function 

 

The studies you posted were for sick or menopausal presumably sedentary people.  I don't think they studied any interaction of vitamin C with exercise, unless I am missing something. 

 

My take-away from all this is that high dose vitamin C is good for vascular function in sedentary or sick people, and probably bad for vascular function in people who exercise (at least if taken within a certain period before or after exercise).  For this reason, I avoid antioxidants on exercise days, but I still take them on sedentary days.

I have investigated and practiced a lot different sports while reading articles. I have decided most natural forms of bodily movements are healthiest. 

Fartlek (Swedish speed play) Running with uneven grounds with moderate injury danger. (simulating in woods running)
Navigating through obstacles using kinesthetic abilities with plyometric workouts (easier forms of parkour)
Long distance swimming and freestyle diving ... (as you navigate to a swim only safe place and hunt fish there) 

And an artificial alternate for maintenance is circuit workout as very low effort and maximum strength and endurance loss prevention.

All these experiential and experimental outcomes are from hundreds of personal trials and a lot reading and thinking ...

Sorry for not prompting a certain study which compares these to synthetic workouts, which I am sure there is one because I ve read it before.
It was emphasizing better coordination of different systems in natural environments.

Edit: Dictionary does not like my words ... underlines and tries to correct them.

It is a bit haunting to note that most researchers seems to consider Vit C, E, NAC and so on to be the gold standard when it comes to antioxidants. Most of these substances have atrocious pharmacodynamics. Maybe this explains the utter failiure of co-supplementation of antioxidants with exercise?
