Electromyographic activity of quadriceps and hamstrings of a professional football team during Bulgarian Squat and Lunge exercises

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 .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

Norm-attaining lattice homomorphisms

In this paper we study the structure of the set Hom(X,R) of all lattice homomorphisms from a Banach lattice X into R. Using the relation among lattice homomorphisms and disjoint families, we prove that the topological dual of the free Banach lattice FBL(A) generated by a set A contains a disjoint family of cardinality 2|A|, answering a question of B. de Pagter and A. W. Wickstead. We also deal with norm-attaining lattice homomorphisms. For classical Banach lattices, as c0, Lp- and C(K)-spaces, every lattice homomorphism on it attains its norm, which shows, in particular, that there is no James theorem for this class of functions. We prove that, indeed, every lattice homomorphism on X and C(K,X) attains its norm whenever X has order continuous norm. On the other hand, we provide what seems to be the first example in the literature of a lattice homomorphism which does not attain its norm. In general, we study the existence and characterization of lattice homomorphisms not attaining their norm in free Banach lattices. As a consequence, it is shown that no Bishop–Phelps type theorem holds true in the Banach lattice setting, i.e., not every lattice homomorphism can be approximated by norm-attaining lattice homomorphisms

A PREVIOUS HAMSTRING INJURY AFFECTS LIMB DOMINANCE IN SOCCER KICKING

The objective of this study was to study if the influence of limb dominance on kicking is affected by a previous hamstring injury to either limb. Forty-five players (26 females and 19 males) belonging to elite soccer teams volunteered to take part in the study. They performed 5 instep soccer kicks with either limb into a target 7m away. Differences were found across limb dominance for the uninjured group in peak linear velocities, hip flexion velocity, knee angle at ball impact, and hip moments. A previous injury prevented the rapid extension of the hamstring muscle fibres, being more predominant in the nondominant limb. Thus the effects of a previous hamstring injury must be taken into account while dealing with the kicking technique, and the location of the injury on the dominant or non-dominant limb is equally important

GENDER EFFECTS ON LIMB DOMINANCE IN KICKING BIOMECHANICS IN ELITE SOCCER PLAYERS

The objective of this study was to study the effect of gender on the limb dominance in kicking in soccer players. Forty-five players (twenty-six females and nineteen males) belonging to elite soccer teams volunteered to take part in the study. They performed 5 instep soccer kicks with either limb into a target 7m away. Female soccer players h d a lesser flexed knee at ball impact in the non-dominant limb which contributed to lower ball velocities in the toe and subsequently in the ball. Both gen&rs had a shorter backswing with the non-dominant limb, but this difference was made up in the follow through for males and in the subsequent phases for females. Working on bilateral symmetry and coordination would help improve kicking with the non-dominant limb, especially in females

EPIDEMIOLOGICAL STUDY OF SPANISH RECREATIONAL RUNNERS

The objective of this study was to analyze how different training aspects and biological factors in running affect the probability of suffering an injury and which muscles and joints are more susceptible to develop an injury. A total of 408 subjects, 206 cases and 202 controls, participated in the investigation. The inferior body was more prone to an injury, especially the muscles and tendons associated with the knee and the shank. Several characteristics of the runner and his/her training habits like the sex, age, experience, motivation and mileage have an impact on the injury risk. This information is very useful because biomechanists and coaches can design programs to improve the technique of the runners and reduce the risk of an injury
