Functional Resistance Training and Affective Response in Female College-Age Students.

INTRODUCTION: Although resistance training (RT) can lead to acute improvements in psychological, physiological and psychosocial outcomes, prevalence rates remain low in college-age females likely due to perceived barriers. This study compared the effects of an acute bout of both a functional RT (FRT) and traditional RT (TRT) session on affect, state anxiety enjoyment and physiological measures.

METHODS: Females (n = 34, mean age = 27 ± 4.5 yr) not currently meeting American College of Sports Medicine RT guidelines completed four sessions (2 FRT, 2 TRT) within 4 wk in a randomized crossover design. Session 1 familiarized participants to the RT exercises. Session 2 consisted of 2 × 10 moderate intensity repetitions. Outcome measures included affect and state anxiety (preexercise, postexercise, and 15 min postexercise); enjoyment (post), and manipulation measures of session RPE and HR).

RESULTS: Between-condition comparisons indicate change scores in state anxiety pre- to post-15 (P = 0.028) and enjoyment levels post- (P = 0.02) were significantly greater in FRT than TRT. Within-condition analyses revealed pre- to post-15 changes in affect were positive and greater in FRT (d = 0.79) than TRT (d = 0.53, P = 0.47), and greater in decreases in state anxiety (FRT, d = -0.58; TRT, d = -0.37, P = 0.028). Mean session RPE was not significantly different between conditions (FRT 6 ± 1.2 units; TRT 6.3 ± 1.1 units; P = 0.11), though average percent of age-predicted maximum HR (FRT 68.7 ± 7.6; TRT 57.1 ± 8.4) was significantly different (P < 0.01).

CONCLUSIONS: Findings suggest that compared with TRT, FRT is associated with higher acute positive psychological states, higher levels of enjoyment, and greater energy expenditure. Future studies are recommended to examine additional measures of affect and in-task timepoints to determine how these responses relate to maintenance and adherence, thereby potentially increasing the proportion of college females meeting American College of Sports Medicine RT and moderate-to-vigorous physical activity guidelines.
