Ylikuntoa on monen tyyppistä, kroonista tai akuuttia, se voi olla paikallista tai koko kehoa vaivaavaa. Kaiken lisäksi ylikunto jaetaan kahteen eri tyyppiin, tai ainakin ennen jaettiin. Tässä vähän Dr. Squattia eli Fred Hatfieldiä :
"Addisonic" overtraining, is named after "Addison's Disease" in which the adrenal and pituitary glands are
malfunctioning. Some of the symptoms of this form of training resemble the disease. This form of overtraining usually
affects older or advanced athletes, and includes a slight overtired feeling, yet no increase in sleep needs, no weight
loss, unusually low resting pulse rate, normal metabolic rate, higher blood pressure, but normal temperature and no
psychological changes.
In "Basedowic" overtraining the name is derived from a disease ("Basedow's Disease") in which
the thyroid function is too high. While no disease, Basedowic overtraining symptoms include: easily tired, reduced
appetite and weight loss, need more sleep, fast resting pulse rate, higher temperature and blood pressure, slower
reaction time, and inability to perform skill movements. This type is more commonly seen in strength athletes and
explosive athletes such as sprinters, jumpers and lifters. It also occurs in young athletes, less advanced athletes, and
in easily excitable ones.
