Evaluation of the isokinetic muscle function, postural control and plantar pressure distribution in capoeira players: a cross-sectional study

Abstract

SummaryBackground: Capoeira is a cultural practice with Brazilian roots that combines several elements including dance, fighting and body rhythm. Because of the diverse elements involved in its practice, capoeira is excellent at developing the physical and social abilities of its players. The aim of this study was to compare the biomechanical profile of muscle strength, plantar pressure distribution, and postural balance between players and non-players of capoeira. Methods: We evaluated 51 subjects who were allocated into two groups: capoeira group and control group. Subjects were evaluated using a baropodometer (Diasu ® ) and an isokinetic dynamometer (Biodex ® ). Results: When comparing plantar pressure distribution between groups and limbs, there were significant differences in mean load of forefoot (p=0.008) and total load (p=0.001). There were no significant differences between groups and limbs in balance and muscle strength; however, a significant difference was found in quadriceps torque peak (p=0.001) and agonist/antagonist ratio (p=0.001) when comparing these variables between the groups. Conclusion:Capoeira players displayed a tendency to have an asymmetric profile in plantar pressure distribution. No difference was found in balance between groups. Despite the fact that capoeira players showed increased strength of the quadriceps muscle, their agonist/antagonist ratio was more asymmetrical than the control group. Level of evidence: IV.

How do sports affect static baropodometry? An observational study among women living in southern Italy

“…Moreover, plantar pressure refers to the pressure measured on the plantar surface of the foot [13], and, of interest, a proper biomechanics of the foot is responsible for upholding body posture and balanced distribution of plantar pressure [1]. However, changes in plantar pressure distribution are linked to many factors that may significantly interfere with physical training and, consequently, sports performance [14]. Remarkably, Potdevin et al [15] investigated plantar pressure asymmetry in order to discuss the opportunity to make a diagnose of pathological gait and guide further rehabilitation process.…”

Stability Training and Effectiveness of Playing Basketball

“…In turn, P. Paula Lima claims -by using the example of people training capoeira -that apart from the strength of torso muscles, a large part in stability is played by the balance between antagonistic groups of muscles. This Mateusz Worobel sport requires many complex movements in which balance plays a major role, allowing the body to adapt to perform them (Paula Lima, Camelo, Ferreira, 2017). Similarly, G. Glofcheskie describes an athlete's ability to adapt to changing conditions during competition and to immediate situations by showing the differences in trunk stabilization in response to immediate situations in athletes and people who do not train.…”

Postural Changes During Exteroceptive Thin Plantar Stimulation: The Effect of Prolonged Use and Different Plantar Localizations

“…Indeed, plantar muscles in both limbs can be activated asymmetrically during standing and walking (Liang et al, 2016). Asymmetric plantar pressure distribution between limbs can be found also in healthy subjects (de Paula Lima et al, 2018), but no studies were carried out to investigate the effects of asymmetric plantar stimulation. The effects of immediate plantar stimulation on postural control have been shown (Christovão et al, 2013), but no studies thus far have assessed the potential effect of prolonged stimulation.…”
