Combined aerobic and resistance training (ATRT) programs are recommended to improve fitness; however, a novel training program focused on individual body type (BT) may provide additional benefits to body satisfaction. PURPOSE: To examine body image dissatisfaction (BID) responses after ~7 weeks of BT training or ATRT. METHODS: Participants (age 19±1y; BMI 23.2±3.5) provided self-report measures of BID (Body Area Satisfaction Scale (BASS), Body Shape Questionnaire (BSQ), and Body Morph Assessment version 2.0 (BMA 2.0)) at baseline and after 15 exercise sessions, 2 d/wk. Participants were randomized to BT or ATRT intervention after classification to a Body Type (Cone®, Spoon®, Hourglass®, or Ruler®) according to circumference measures. BMA 2.0 assessed perceived current body size (CBS), selected ideal body size (IBS), selected acceptable body size (ABS), and BMA-BID (CBS-IBS). Given this was an efficacy trial, intent-to-treat (ITT; n=132) and per protocol (PP; BASS, BSQ n=77; BMA n=93; completed ≥ 10 of 15 supervised sessions) data analyses were utilized. RESULTS: Overall, body image scores decreased with a trend observed for the BMA-BID (baseline: 5.5 95%CI(4.5-6.5); follow-up: 4.8 (3.9-5.8); P=0.07) after exercise training indicating improvements in BID. Results were similar among ITT and PP analyses. Increases in BID were seen in the ATRT group with significantly lower BASS scores compared to BT group at follow-up (ATRT= 2.61 vs. 2.45; P < 0.05). Participants in the ATRT group saw themselves as smaller and set a smaller acceptable goals based on significant reductions in CBS and ABS relative to BT. Sum circumferences were different after both programs (BT = -6.2cm; 95% CI -1.9, -10.7cm; ATRT = -7.5cm; -3.3, -11.7cm); however, changes in body satisfaction were not related to changes in total body circumferences (P>0.05 for all). CONCLUSION: Baseline scores for BID suggest women in this study were generally unsatisfied with their overall body image (BASS < 3.0, BSQ > 80). In general, BT and ATRT produced similar responses; exercise reduced CBS—thereby reducing the difference between CBS and IBS—improving overall body satisfaction regardless of changes in body composition.
