Functional Performance of Ankles Between Male and Female Practitioners of Resistance Exercise

Background. Gender difference has shown that females exhibit a greater the ankle range of motion (ROM) than males. On the other hand, few studies have examined the link between the ankles ROM, muscle strength and functional performance (FP) in the gender difference. Objective. The purpose of this investigation was to compare the ankles ROM, ankle isometric muscle strength and ankle PFP between males and females practitioners of resistance exercise. Methods. Males (n = 20) and females (n = 20) healthy were recruited. All participants underwent three tests to assess the ROM, muscle strength and FP of the ankles, respectively. ROM measurements were taken in both ankles with a digital goniometer. Ankle isometric muscle strength was measured using a load cell. Ankle FP was assessed with the Single Leg Hop Test (SLHT) in both limbs. Results. Plantar flexion ROM was significantly greater in the females than males for both ankles (p < .01). No significant difference (p > .05) was found between the groups for ankle-dorsiflexion ROM. Isometric muscle strength during dorsiflexion was significantly lower in the females for both ankles (p < .01). SLHT showed demonstrating better FP in the males (p < .001). Isometric muscle strength during plantar flexion was significantly correlated with plantar flexion ROM in males (r = 0.52; p < .02) and females (r = 0.46; p < .03). Conclusions. This study showed the better ankles FP and greater isometric muscle strength during ankle-dorsiflexion and plantar flexion in males. On the other hand, plantar flexion ROM was greater in females.
