Acute Effects of Resistance-Exercise Intensity in Depressed Black/African Americans Living With HIV: A Randomized Pilot Study

J Sport Exerc Psychol. 2019 Oct 1;41(5):261-270. doi: 10.1123/jsep.2018-0301.

Abstract

Depressive symptoms and fatigue are prevalent among people living with human immunodeficiency virus. Resistance exercise is known to stimulate a positive affective response.

Objective: To examine the acute psychological effects of resistance-exercise intensity among Black/African-American people living with human immunodeficiency virus and experiencing depressive symptoms.

Methods: A total of 42 participants were randomized into a moderate- (n = 21) or high-intensity (n = 21) group. Assessments were collected before exercise (PRE), at the midpoint (MID), immediately following (POST) exercise, and 15 (DELAY 15) and 30 (DELAY 30) min after.

Results: In the moderate-intensity group, affect improved PRE to POST, PRE to DELAY 15 and DELAY 30, and perceived distress decreased from PRE to all time points. In the high-intensity group, affect declined PRE to MID, and perceived distress decreased PRE to DELAY 15 and DELAY 30. Perceived activation increased PRE to MID, and POST in both groups (ps < .01).

Conclusions: The moderate-intensity group compared with the high-intensity group is more effective at improving affect and energy and at reducing distress.
