Exercises and activities such as maximum effort strength training (90 % of 1RM above); high intensity plyometric, explosive speed and power drills, such as sprints and jumps, etc., are all
very taxing on the CNS and can
lead to this type of
overtraining when performed with too much frequency, volume and intensity.
It can be a
very good thing — except that staying in prolonged state of inflammation (for example
overtraining, constantly eating irritating foods, long - term emotional or psychological distress) can
lead to health problems and disease.
