Abdominal / adductor strength imbalance in soccer players with osteitis pubis

Mohammad, WS; Elsais, WME

Abstract

Background and Objective:
The muscle imbalance between abdominal and hip adductor muscles as an etiology for osteitis pubis is not
well understood. The concept of a relationship between eccentric/concentric ratios at the pelvis and osteitis
pubis in athletes is limited. This study aimed to compare the eccentric/concentric ratios for abdominal/
adductor, abdominal/back, and hip adductor muscles as well as eccentric abdominal/eccentric adductor
muscles in soccer players suffering from osteitis pubis with those in healthy athletes.
Material and Methods:
Twenty male soccer athletes with osteitis pubis were recruited to participate and 20 healthy male soccer
athletes were recruited to participate. Peak torque/body weight (PT/BW) for the hip adductor, abdominal,
and back muscles during isokinetic concentric and eccentric contraction modes at a speed of 180°/s was
recorded for healthy players and soccer athletes with osteitis pubis. Eccentric/concentric ratios for the
abdominal/adductor, abdominal/back, and hip adductor muscles and the eccentric abdominal/eccentric
adductor muscles were measured for both groups.
Results:
There was a significant decrease in the eccentric abdominal/concentric hip adductor muscles ratio
(p = 0.000) and in the eccentric/concentric hip adductor muscles ratio (p = 0.016) between the osteitis pubis
group and the healthy control group.
Conclusion:
Soccer players with osteitis pubis present with strength imbalance. The osteitis pubis group displayed eccentric
weakness of the abdominal and adductor muscles, resulting in imbalances in the normal eccentric abdominal/concentric adductor and eccentric/concentric adductor ratios. Therefore, exercises that increase
the eccentric strength of abdominal and hip adductor muscles may be beneficial to include in rehabilitation
programs of patients with osteitis pubis.
