i think all of the above are correct. i only have one fact to add. many clients personal life can affect their training. i have found it to be hard to decide if it is overtraining or emotional stress from the outside. I usually have a good repore with my clients so, i just ask. Sometimes their training is all they have to comfort them. so, i make adjustments in the program to suit there need at that time. It is a hard world out there.
I know that you can get all kinds of lists illustrating the endless signs and symptoms for overtraing, so I wont just cut and paste. I will speak from a practical standpoint.
As a trainer, I think it is very important to remember the “personal” part of our title. For me, I start wonder about overtraing in my clients when their dedication and desire to workout starts to dwindle. I think there are obvious physiological signs but a lot of times we won’t see or hear about those from our clients, its normally when their performance will start to decline or they start missing appointments more than usual that get me to investigate overtraing.
Hope this helps,
The signs and symptoms can be varied:
-increased heart rate upon waking
-diminished training gains (not able to lift the same amount of weight or run at the same pace/distance)
-sudden weight gain or loss
-loss of interest in things you used to like to do
-moodiness or mood swings
