Adherence to exercise interventions aimed at improving cardiac health in sedentary women may be affected by lack of time to exercise. This study evaluated the efficacy and acceptability of short-bout football training (twice weekly for 13.5 min. over 16 weeks) in sedentary pre-menopausal women using 31P spectroscopy to assess metabolic adaptations in muscle. Results indicated a significant increase in time-to-failure on a ramp muscle test and a significantly higher end-exercise PCr value in participants after exposure to the training intervention. Evidence that shorter training regimes improve cardiac health may reduce barriers to exercise and increase compliance in target populations.
