Twenty-four injury-free male basketball players (mean age 20\u2009[3]\u00a0y) were randomly assigned to a 12-week intervention (n\u2009=\u200913) or control group (n\u2009=\u200911). The primary outcome measures were normalized muscle activity (percentage of maximal voluntary isometric contraction, %MVIC) and relative contribution of hamstring muscles over 12\u00a0weeks. No effects were found on any of the primary outcome measures. Between-group differences over 12\u00a0weeks were 2.7%MVIC (95% confidence interval 95% CI, \u22120.7 to 6.1) for the biceps femoris long head, 3.4%MVIC (95% CI, \u22121.4 to 8.2) for the semitendinosus, and 0.8%MVIC (95% CI, \u22123.0 to 4.6) for the semimembranosus, <jats:italic>P<\/jats:italic>\u2009=\u2009.366. Between-group differences over 12\u00a0weeks were 1.0% relative contribution (%con; 95% CI, \u22123.0 to 5.1) for the biceps femoris long head, 2.2% relative contribution (95% CI, \u22122.8 to 7.2) for the semitendinosus, and \u22123.3% relative contribution (95% CI, \u22126.4 to \u22120.1) for the semimembranosus <jats:italic>P<\/jats:italic>\u2009=\u2009.258.
