Athletes who are really overtrained might feel more depressed or moody than those who are just temporarily worn out, and these mood changes could be an early red flag that something's wrong.
Doctors can't use a single blood test or scan to diagnose overtraining — instead, they have to rule out other health problems and see if an athlete's performance keeps dropping for no clear reason.
Overtraining isn't just being tired — it's when an athlete's body stops working properly and performance drops for a long time, even after resting, and it's different from regular burnout that goes...
When you hurt a chewing muscle, your body might produce more of a protein called NGF, which could make the nerves in that muscle extra sensitive over time and lead to long-lasting pain.
If you regularly clench or grind your teeth, it might keep injuring the jaw muscles, and if those muscles can't heal properly, it could lead to long-term jaw pain.
If you keep injuring your jaw muscles, it might make the pain-sensing nerves more sensitive over time, which could lead to long-lasting muscle pain.
When jaw muscles get injured over and over, they don’t get tougher like arm or leg muscles do — instead, they get more damaged and weaker each time.
Your jaw muscles don't heal as well after injury compared to leg muscles — they get scarred and don't fix themselves properly, at least in animal studies.
In young active women, doing repeated rounds of intense arm exercises doesn’t change how muscles handle calcium, so that’s probably not why they get more resistant to soreness over time.
When active women do tough arm exercises over and over, their brain’s ability to fire muscles stays strong — it doesn’t drop, so the nervous system probably isn’t why they get less sore over time.
In young, active women, hormone levels don’t seem to change how well their muscles recover after a tough workout — whether they’re on birth control or not, their soreness and strength come back at...
Doing a tough arm workout twice, four weeks apart, helps women's muscles bounce back faster the second time—even if they're on birth control or where they are in their cycle.
In young, active women, having higher natural estrogen levels doesn’t seem to protect against muscle soreness or weakness after intense arm exercises — it hits just as hard as when estrogen is low,...
If you're under a lot of long-term stress, your muscles might not recover as well after a tough workout — and you might feel more sore or off for days afterward.
If young adults are under a lot of stress in their lives, they might feel sore for longer after a hard workout — the more stressed they are, the longer the soreness seems to stick around.
If young adults feel more stressed, they might bounce back more slowly after a tough workout — especially when it comes to how high they can jump.
If young adults are under more long-term stress, they might feel more tired, less energetic, and more sore for longer after a hard workout.
If you're a young adult lifting heavy weights, being under a lot of long-term stress might slow down how fast your muscles bounce back—even if you're fit or experienced.
Stress from life events might slow down how quickly young adults who work out regularly can regain muscle strength after a tough workout — and it could be a pretty big factor, even if they're fit.
Stress doesn't seem to change how quickly young adults feel less tired or sore right after a hard workout.
If young adults feel more stressed, their muscles might not recover as quickly after a tough workout — and this isn't just because of how fit they are or how hard they worked out.
If you're a young adult lifting heavy weights, being under more long-term stress might slow down how quickly your muscles bounce back in the hour after your workout — even if you're fit and used to...
If young, healthy guys do certain muscle exercises before having one leg kept still for a week, it doesn’t really help keep the muscle from shrinking — both those who did the exercises and those who...
If young, healthy guys do certain muscle-damaging exercises before their leg is immobilized, their muscles might waste away less—even if their muscle-building activity goes down. Without those...
