Weird type of muscle failure, Maybe nervous system adaptation??

Hey guys today i trained chest and i went the heaviest i've gone on decline db press. I went up to 90's for the first time, the set before i did the 80's for a solid set of 5 which i also had never used, Didn't go to failure on that set as well. I was a little shaky with the 80's but figured i could probably get the 90's for a good set of possible 5. Anyways i got the first rep: perfect chest contracted super hard, lowered super slow and fired up the 2nd one..WHAM another perfect rep super controlled. At this point i definitely was thinking 5 reps, went to hit the 3rd rep and got about to lockout and left arm just "stopped contracting" no tear symptoms or anything it just like i said stopped. I have had this happen with overhead press trying a new weight as well. Does this sound like a nervous system adaptation to you guys? I figured it makes the most logical sense because it's A: A new weight and B: The weight was heavy but my chest contractions were super intense.

Reps were done with 3-4 second negatives too but i still felt really strong and in control, just kind of a goofy situation! I'm just happy no tear, i think i'd attribute that to how slow i was doing the reps WHEW

Man thats just failure. Failure isnt accompanied by a burn or killer pump when youre going heavy like that. Its still muscular failure tho. Nothing more. Nothing less.

It sounds like some sort of neural or tendinous impingement the way you described it. Muscular failure will be associated with a longer duration of tension (ie..being able to push for 3-8 seconds, or resist the load coming down). If your arm just gave out, then that was either due to a lack of neural impulse, likely due to an acute impingement, or perhaps one of the RC muscle tendons or nerves that recruits it getting impinged.
