However, little is known about the effects of strength exercise on emotional aspects. Methods: nineteen people diagnosed with KOA and age of 50 and 80 years, were subject of an 8-week muscle strengthening training protocol, three times a week. The evaluation of the physical and emotional aspects was carried out before starting the training and repeated up to five days after the end of the eight weeks of intervention, both by the same physiotherapist, blind, and properly trained. Results: it was noted that there was no difference in the Positive and Negative Affect Schedule (PANAS), as well as in any of the Pain Catastrophizing Scale (PCS) sub-items. Only the Beck Depression Inventory (BDI) has improved, showing the reduction in the level of depression. Conclusion: the strength exercises promote a decrease in depression levels, but it does not have the same effect related to catastrophic thoughts or negative affect.
