A comparison of once versus twice per week training on leg press strength in women
One article on PainSci cites Burt 2007: Strength Training Frequency
PainSci commentary on Burt 2007: ?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided wherever possible.
Burt et al compared “strength differences between 2 groups of untrained women, who performed a single set of the leg press exercise once or twice per week.” There was no difference in their results. “These results indicate that performing a single set of the leg press once or twice per week results in statistically similar strength gains in untrained women.”

AIM: The purpose of this study was to compare strength differences between 2 groups of untrained women, who performed a single set of the leg press exercise once or twice per week.
METHODS: Twenty-one women were divided randomly into 2 groups: Group 1 (n=10) performed a single set of the leg press exercise once per week, while Group 2 (n=11) performed a single set of the leg press exercise twice per week for a period of 8 weeks. Throughout the duration of the study, an amount of resistance was utilized that allowed for a single set of 6 to 10 repetitions to muscular failure. At the conclusion of the study, subjects were tested for their 6-RM strength. A 2x2 ANOVA was used to compare strength differences. The a level was set at 0.05 in order for differences to be considered significant.
RESULTS: The 2x2 ANOVA demonstrated that strength increases were significant between tests (P=0.0001), but not significant between groups (P=0.757).
CONCLUSIONS: These results indicate that performing a single set of the leg press once or twice per week results in statistically similar strength gains in untrained women.
