BACKGROUND: This study examined the effect of a personal trainer’s sex on self-efficacy and fitness in woman clients.
METHODS: Women (n: 28; mean ± SD; age, 41.6 ± 15.0 yrs.; height, 153.49 ± 28.11cm; BMI, 25.9 ± 6.4 kg•m-2) completed a perceptual scale of self-efficacy (BARSE) and fitness tests before and after a training program. Trainers (men and women) met one-on-one with the volunteers on a biweekly basis for 8 weeks. Univariate analyses of change scores and repeated measures analysis of variance with Fisher’s LSD pairwise comparisons tested changes in dependent variables by trainer sex.
RESULTS: Significant increases were seen in (mean ± SE; change for men trainers; change for woman trainers): self-efficacy (7.3 ± 3.4; 7.3 ± 2.7%); leg press strength (18.2 ± 3.7; 16.4 ± 3.3 kg); seated row (6.1 ± 1.5; 5.3 ± 1.3 kg); muscular endurance in 60° flexion hold (20.5 ± 5.8; 24.8 ± 5.0 sec) and wall-sit (19.9 ± 6.4; 33.5 ± 5.8 sec); but not flexibility (V-sit, 7.11 ± 5.51; 4.23 ± 4.50 cm). Chest press strength significantly increased for women trainers only (2.7 ± 2.2; 5.3 ± 1.8 kg). Despite this, there were no significant differences for any variable in the change from pre-to-post based on the sex of the trainer.
CONCLUSIONS: Both men and woman-led training was effective for increasing markers of self-efficacy and fitness in woman clients.
