Background Reduced hip adduction strength has been identified as a key predisposing factor in developing hip and groin injuries.The Copenhagen adduction programme has been shown to increase hip adduction strength in semiprofessional footballers but can cause muscle nst2018 black and decker soreness.Therefore, a modified progressive Copenhagen adduction (MPCA) programme has been designed to increase hip adduction strength while limiting muscle soreness.Objective To investigate the effect of an 8-week MPCA exercise on eccentric hip adduction and abduction strength in senior professional footballers.Methods 25 senior professional footballers completed an 8-week MPCA strengthening programme.

Eccentric hip adduction (EHAD) and eccentric hip abduction (EHAB) strengths were measured.Changes in preintervention and postintervention strengths and EHAD:EHAB ratios were calculated.The statistical significance between strength changes was assessed with dependent t-tests and Wilcoxon signed-rank tests orb grinder due to the distribution of the data (p<0.05).Delayed onset of muscle soreness (DOMS) and rate of perceived exertion were measured throughout the programme.

Results There were statistically significant increases in EHAD strength (24% and 25%, left and right), EHAB strength (10% and 13%, left and right) and the EHAD:EHAB ratio (12% and 10%, left and right) (p<0.01).Professional footballers were able to complete the MPCA exercise with low levels of DOMS.Conclusion An 8-week MPCA exercise elicited significant EHAD and EHAB strength increases with reduced levels of muscle soreness in senior professional footballers.
