A blinded assessor took measures at baseline and at 10‐week follow‐up; participants performed maximal voluntary contractions at a static 90‐degree shoulder joint angle. Rapid force development was determined as the rate of torque development and maximal muscle strength was determined as the peak torque.</p> </sec> <sec id="cpf12041-sec-0003" sec-type="section"> <title>Results</title> <p>Compared with the control group, rate of torque development increased 31·0 Nm s<sup>−1</sup> [95% confidence interval: (1·33–11·80)] in the 2‐min group and 33·2 Nm s<sup>−1</sup> (1·66–12·33) in the 12‐min group from baseline to 10‐week follow‐up, corresponding to an increase of 16·0% and 18·2% for the two groups, respectively. The increase was significantly different compared to controls (<italic>P</italic><0·05) for both training groups. Maximal muscle strength increased only ~5–6% [mean and 95% confidence interval for 2‐ and 12‐min groups to control, respectively: 2·5 Nm (0·05–0·73) and 2·2 Nm (0·01–0·70)]. No significant differences between the 2‐ and 12‐min groups were evident. A weak but significant relationship existed between changes in rapid force development and pain (<italic>r</italic> = 0·27, <italic>P</italic><0·01), but not between changes in maximal muscle strength and pain.</p> </sec> <sec id="cpf12041-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Small daily amounts of progressive resistance training in adults with frequent neck/shoulder pain increases rapid force development and, to a less extent, maximal force capacity.</p> </sec> </abstract>
