Yes i agree that we should not get too carried away with only discussing small details, while at the same time recognizing that many training errors are made because of not paying attention to the small details.
If a person uses resting heart rate, they should definitely be doing some manner of orthostatic protocol, as resting heart rate alone is too ambiguous. Orthostatic simply refers to the relationship of standing to something, in this case seeing what standing does to heart rate. You can either be seated or laying down to start and either stand or sit on your bike as Juerg suggested. The whole time you must not talk or move quickly. You will measure the lowest heart rate while seated or lying down, and compare this to the lowest heart rate while standing.
Try this for a few weeks and see the relationship to your training and how you feel.
I didn’t know intraocular pressure was decreased by long endurance training, this is very useful information. i did know it was increased by strength training.
very good question; does fatigue/ overreaching/ overtraining show up as increased intraocular pressure?
research supporting endurance exercise reduces intraocular pressure:

Exercise training reduces intraocular pressure among subjects suspected of having glaucoma.

The effect of exercise conditioning on elevated intraocular pressure has not been previously described among sedentary individuals. We prospectively observed intraocular pressure for nine sedentary subjects suspected of having glaucoma before and after 3 months of aerobic exercise training. Mean (+/- SEM) aerobic capacity, as assessed by maximal oxygen uptake, increased 6.3 +/- 1.6 mL.kg-1.min-1 (30%) (P less than .02). Mean intraocular pressure decreased 4.6 +/- 0.4 mmHg (20%) (P less than .001) at the end of the conditioning period. With cessation of exercise and subsequent detraining, intraocular pressure returned to elevated preconditioning levels by 3 weeks. Regular aerobic exercise is associated with a reduction in elevated intraocular pressure and may represent an effective nonpharmacologic intervention for patients suspected of having glaucoma.

Effects of exercise on intraocular pressure in physically fit subjects.

1. Several studies have shown that exercise reduces intraocular pressure (IOP) in sedentary subjects, but the effects of exercise in physically fit subjects are not fully known. Accordingly, the present study was planned to investigate the effects of exercise on intraocular pressure in physically fit subjects after elimination of those factors that can affect intraocular pressure and have been neglected by previous studies. 2. Thirty-two sedentary males of the same age group were categorized equally into control and experimental groups. Intraocular pressures were measured during and after exercise with the Goldmann applanation tonometer. The experimental group took a supervised exercise programme of 3 months duration. Physical fitness was evaluated by the measurements of maximum oxygen uptake. Each subject was tested twice by the same exercise protocol at an interval of 3 months. 3. After 3 months, resting IOP values decreased by 0.31 +/- 0.11 (P < 0.05) and 1.37 +/- 0.15 mmHg (P < 0.001) in control and experimental groups, respectively. The acute decreases following the first exercise test were 4.18 +/- 0.41 and 4.38 +/- 0.47 mmHg, while after 3 months these values were 4.12 +/- 0.45 and 2.69 +/- 0.28 mmHg in control and experimental groups, respectively. After exercise conditioning, the mean recovery time was reduced by 43.03%. 4. The results are relevant to planning trials in glaucoma. Physical fitness reduces IOP and causes significant attenuation in the IOP response to physical exercise. It would seem reasonable at present not to discourage patients who have glaucoma from light exercise; perhaps, on the contrary, it should be encouraged.
