Abstract
The purpose of this study was to study the effects of resistance training combined with different attentional focus on thigh muscle size and muscle strength. Twenty – four untrained men college (age 18 – 30 years) were selected with purposive sampling and randomly assigned to an internal focus combined with resistance training group (experimental group), and an external focus combined with resistance training group (experimental group), and a common resistance training group (control group). All three groups performed a same exercise (machine leg extension) with 3 day per week for 6 weeks. Quadriceps muscle cross-sectional area test, Isometric knee extension strength test and 1RM knee extension strength test were measured before and after training, Data were analysed using Two-factor Mixed-design ANOVA with repeated measure. Electromyography (EMG) were assessed in training week 1 and week 6, Data were analysed using One-way ANOVA. A level of significant was set at p-value < .05.
After 6 weeks of training, all three groups show similarly significant increase in Quadriceps muscle cross-sectional area, Isometric knee extension strength and 1RM knee extension strength, with no significant differences between groups. There was significant higher for EMG value in internal focus group than external focus group and control group.
Resistance training combined with internal focus was not effective in increasing thigh muscle size and muscle strength when compared with external focus and common resistance training. If attempting to maximize thigh muscle activation, an internal focus would seem to be a better choir.
