Strength and Body Composition Changes in Recreationally Strength-Trained Individuals: Comparison of One versus Three Sets Resistance-Training Programmes

Table 2

Means ± sd for measured strength performances and body composition characteristics from both training groups after the eight-week training intervention. Confidence intervals (95%), effect sizes and power (95%) for statistically significant results are also provided.

Variables	One-set training group (𝑛=8)	Three-set training group (𝑛=8)	Mean difference	95% confidence interval	Effect size	Power (%)
Bench press (𝑁)	776.2±121.5	789.9±96.0	13.7
Biceps curl (𝑁)	485.1±48.0	499.8±77.4	14.7
Shoulder press (𝑁)	527.2±74.5	510.6±62.7	16.6
∑7SF (mm)	61.8±19.5	66.2±17.9	4.4^∗	−24.5 to 15.7	0.24	7.8

∗Result is statistically significant (𝑃≤0.05) on a two-tailed test.
