ABSTRACT

The aim of this study was to analyse the quadriceps-hamstring coactivation in the lunge and Bulgarian squat exercises. A cross-sectional study design was applied to seventeen healthy professional football players. Muscular activity was measured using wireless surface electromyography (sEMG). The Maximum Voluntary Isometric Contraction was used to normalize the data. The muscle activation of each muscle belly was significantly different between the two exercises (F4.24 = 28.076, p < .001, partial ƞ 2 = .72). Activity in individual muscles varied in both the lunge (F4,24 = 49.315, p < .001,partial ƞ 2 = .89), and the Bulgarian squat (F4,24 = 28,076, p < .001,partial ƞ 2 = .82). The results showed no significant differences between the preferred and non-preferred legs of the participants (p > .05). In both the lunge and the Bulgarian squat, a significantly greater activation of the vastus medialis (VM) and the vastus lateralis (VL) muscles were found compared to the rectus femoris (RF) and biceps femoris (BF) and semitendinosus (ST). Muscles showed a greater activation during the Bulgarian squat compared to the lunge, but the hamstrings to quadriceps ratio was similar in both exercises (p > .05). The present work shows that the Bulgarian Squat exercise produces greater muscle activation than the Lunge exercise, whereas in both exercises there is a similar pattern of muscle activation. No differences were found between legs. If one wants to work specifically on strength development, the Bulgarian Squat would be a better option, as would be the case if one were to focus on synergistic work on the quadriceps and hamstrings, as the Bulgarian Squat exercise shows a higher H:Q ratio.

ABSTRACT

As biomechanists, improving technique with an aim of injury prevention is an essential application of biomechanics in recreational runners. A mixed sample of elite and recreational runners, belonging to either sex, could give useful movement patterns of movement. In order to obtain any useful pattern of movement we would like to know if we should use an elite or a recreational sample as a reference also differencing in sex. A total of 48 runners participated in this study: 12 female amateurs, 38 male amateurs and 8 male professionals. Running gait parameters and sagittal plane kinematics from the hip, knee and ankle and frontal plane kinematics from the foot were recorded at a selfselected speed for the amateurs and the speed of the elite athlete was adapted to that of the amateurs. Differences in sex were found at the self-selected speed, stride length and hip extension at foot off (p<0,005). Differences in running level were found in the swing phase and in knee flexion at foot contact.

Keywords: kinematics, sagittal plane, gait parameters, comparison, amateur and elite.
