3-4 training sessions per week.

(1) <7.5 MET (<150 mins/week of moderate-intensity PA)
(2) 7.5–21 MET of moderate intensity
(3) >21 MET (>420 mins/week) of moderate intensity
Women who exercised 420 minutes per week (60 mins a day) in a moderate-intensity activity gained less than 2.3 Kg in three years.

Participants who were never medically suspended (NMS) and those who were suspended but returned (SR) improved a lot.

KKW: kilocalories per kilogram of body weight per week, QOL: quality of life, MET: metabolic equivalent hours per week, EC: experience corps, NMS: never medically Suspended, SR: medically suspended but returned.
