The purpose of this study is to determine the effectiveness of an in-season resistance training program on improving measures of strength in female collegiate triathletes. Nine females (age = 19.2 ± 1.1 years, height = 166.5 ± 12.5 cm, body mass = 61.1 ± 9 kg) with limited resistance training experience were examined for this study. Formal RT intervention was monitored for 7 weeks with the athletes being assigned 6 weeks of independent RT prior to the pre-test. Athletes completed a standardized athlete monitoring program pre and post resistance training intervention. Paired sample t-tests were used to determine differences between conditions with Cohen’s d effect sizes describing the magnitude of change between pre and post-intervention. No significant changes were found between the two testing sessions (p > 0.05). A longer duration of utilizing resistance training adhering to a phase potentiated approach may be necessary for significant changes to occur.
