High intensity resistance training as intervention method to knee osteoarthritis.

High intensity resistance training (HI-RT) is a treatment option for Knee Osteoarthritis (KOA). Isotonic machines (leg press, leg extension) are utilized for standardization and reproducibility reasons, but the load used during the protocol is often low, considering that elder people usually have low strength levels, training so with high intensities calculated on low loads. The physiological response of an elder woman trained with high loads on a free weight exercise, the regular barbell deadlift, with a 1 Repetition Maximum (1RM) of 100 kg, can be appreciated in this report, so that for the first time we can see the effect of a one year of high intensity resistance training program on a powerlifting exercise on a 72 year-old woman with KOA.
