Day 1.) I was starting a jump training routine (I've done this routine several times before). Warmed up fine, but 10 minutes into the jump training routine I got the same feelings described in day 2 below.
Day 2.) (4:20pm in the day) I warmed up on a stationary bike just before going to a treadmill and my heart rate was at a steady 110/120 with no problems. While on the treadmill, I started off at 3.0 mph for 5 minutes, then up to 5.3 mph and then suddenly felt weak, tired, dizzy, cold sweaty, and my heart rate dropped from 130 to 89. After stopping and getting off the treadmill, the dizziness got stronger, my hearing went a little muffled and my heart rate dropped to 59. It felt like I was going to pass out (I've never passed out before). A minute or two later and some deep breaths my heart rate returned to the high 90's and low 100's and the dizziness was gone. This never happen to me before, now it has happened twice in the past two days.
I was able to do a weight training (Back and Biceps) session earlier in the morning (8:30am) with a steady heart rate of 125.
Some suggested I "BONKED" but I have read about Vasovagal, Pre Syncope, Bradycardia, and Angina. Any idea's what is happening?
