Effect of Regular Resistance Training on Motivation, Self-Perceived Health, and Quality of Life in Previously Inactive Overweight Women: A Randomized, Controlled Trial.
Objectives. The aim was to investigate the effects of three different types of resistance training implementation. Design. Randomized controlled trial. Methods. Inactive, overweight women (n = 143), mean BMI 31.3 ? 5.2?kg/m(2), mean age 39.9 ? 10.5 years, were randomized to one of the following groups: A (BodyPump group training), B (individual follow-up by a personal trainer), C (nonsupervised exercise), or D (controls). The intervention included 12 weeks of 45-60 minutes' full-body resistance training three sessions per week. The outcomes in this paper are all secondary outcome measures: exercise motivation, self-perceived health, and quality of life. Results. Adherence averaged 26.1 ? 10.3 of 36 prescribed sessions. After the intervention period, all three training groups (A-C) had better scores on exercise motivation (A = 43.9 ? 19.8, B = 47.6 ? 15.4, C = 48.4 ? 17.8) compared to the control group (D) (26.5 ? 18.2) (p
