Most ACL injuries are non-contact and are associated with biomechanical risk factors that increase tension in the ACL: increased knee valgus (KV) and hip flexion (HF) and decreased flexion of knee (KF). Muscle around the knee contributes to knee stability, so fatigue produced by exercise could alter knee balance, increasing LCA tension. The aim of the study is to determine the angular behavior before and after a physical load for CF, RR and RV in children born in 2002-2003. A non-randomized clinical trial was conducted. The sample consisted of 50 students from soccer schools born between 2002 and 2003. The angular behavior of CF, RR and VR was compared, before and after performing standardized training. The angular behavior was measured by performing the DJ test with data obtained by inertial sensors. After exercise, the 3 variables increased, but only HF reached significant difference. Other imp...

In most cases, ACL injuries do not require external contact and they are associated with biomechanical risk factors that increase ACL tension. The increase of the hip flexion angle (HF) is included within these. The ACL requires cooperation of the periarticular musculature of the knee, muscle groups, hip stabilizers and CORE muscles; consequently, fatigue caused by exercise would alter the balance and put this ligament at risk. The objective of the study is to determine the angular behavior for HF before and after a physical load (a standardized training) in children between 11 and 12 years old. A non-randomized clinical study was carried out. The sample consisted of 50 soccer school students born between 11 and 12 years old. The angular behavior of HF was compared before and after performing a training session. The angular behavior was measured through the Drop Jump test (DJ), with data obtained b...

La lesió n del ligamento cruzado anterior (LCA) constituye una causa importante de reposo en deportistas. En su mayoría, las lesiones del LCA no requieren contacto externo y se asocian con factores de riesgo biomecánicos que aumentan la tensión en el LCA: el aumento del ángulo de valgo de rodilla (VR), fl exión de cadera (FC) y una menor fl exión de rodilla (FR). El LCA requiere cooperación de los grupos musculares perirrodilla, por lo que la fatiga producida por el ejercicio alteraría el balance y pondría en riesgo a este ligamento. El objetivo del estudio es determinar el comportamiento angular antes y después de una carga física para FC, FR y VR en niños nacidos en los años 2002-2003. Se realizó un estudio clínico no aleatorizado. La muestra consistió en 50 alumnos de escuelas de fútbol nacidos en los años 2002 y 2003. Se comparó el comportamiento angular de FC, FR y VR antes y después de realizar un entrenamiento estandarizado. El comportamiento angular fue medido a tra...

The implementation of this training program will generate morpho – physiological changes between players exposed. Federation International Football Association (FIFA) created a training program known as the "11+", designed to amend morpho-functional parameters such as lower extremity alignment, strength, intra, and inter muscular coordination and balance, among others. Subjects: Information indicates that injuries are a serious cause of concern for the soccer clubs and therefore, it is necessary to introduce the prevention programs. Methods: 20 female players of the National Chilean Sub-17 Soccer Team, from 14 to 17 years, who trained from March 2017 to January 2018. The “The 11+” warm-up program was considering an independent variable and thigh circumference, jumping ability, speed and balance are consider...

Most ACL injuries do not require external contact and are associated with biomechanical risk factors that stress this ligament ACL: like an increase in knee valgus angle (KV) and hip flexion (HF) and a decreased in knee flexion (KF). The ACL requires muscle cooperation to resist the load; however, when there is fatigue, the protective capacity of the musculature would decrease. The objective of the study is to analyze the angular behavior before and after a physical load for HF in children of 14-15 years old. Hypothesis The physical load applied in a single training session is enough to change some biomechanical risk factors of ACL injury. Study Design Experimental study Level of Evidence 2b Methods The sample consisted of 50 students from different soccer schools between 14-15 years old. We analyzed the hip ang...

Background: Proprioception is a cornerstone for maintaining joint and postural stability. Dynamic stability is particularly emphasized within these components. This feature is important in the rehabilitation field. Therefore, the quest for elements to improve these values can bring advantages in sports. Objectives: Evaluate if there are advantages in the performance of a Star Excursion Balance Test (SEBT) using Kinesio taping. Methods: We evaluated 10 professional soccer players from the Chilean women’s national team. They were randomly divided into 2 groups. One group had Kinesio taping and their SEBT performance was evaluated. The other group performed the measurements without the use of Kinesio Taping. Afterward, each group performed the evaluation they did not do during the first stage. We then compared the performance achieved with and without the use of Kinesio Taping Results: There were significant differences in the...

If these situations are not properly controlled they can cause the athlete chronic fatigue, an increase in delayed-onset muscle soreness (DOMS) and thus result in a decrease in athletic performance. There are several therapies that have attempted to improve athletic performance, decrease the percentage of injuries and results in soccer. Training and recovery instances are opportunities to find ways to address this issue. Understanding the physiology of recovery is essential to accelerate some processes, with the aim of shortening the times. Subjects: Cryotherapy could improve functional performance tests and decrease pain in soccer players. Our work design is an experimental prospective study. Method: Twenty subjects (10 experimental subjects and 10 control group subjects), between the ages of 17 and 23, who are members of a university men's soccer team, participated in the study. The following variables were controlled: pow...

Measurement of lactate concentration in blood seeks to indirectly gauge physiologic responses to the increase in physical exercise. Swimmers face multiple maximal-exertion events during competition. Strenuous physical exercise leads to fatigue and, thus, a decrease in sports performance. Regeneration exercises in swimming increase the clearance of blood lactate and therefore improve athletic performance within a single day of competition. Crossover study. Level 1. Of 25 swimmers, 21 were included, with a mean age of 17 years. They performed exercises that increased blood lactate on 2 days. The protocol was a warm-up, followed by a 100-m freestyle workout at full speed. Swimming exercises followed that were increasingly demanding, during which serial lactatemia measurements were taken. On the first day, regeneration exercises were performed; on the second day, the swimmers rested. Next, lactatemia was measured, and a timed 100-m freestyle workout was performed at maximum speed. The stress exercises increased the mean lactate concentration by 4.6 mmol/L, which corresponds to 78% of the initial basal level. The postregeneration lactatemia level was lower than that after resting (mean, 2.76 vs 6.51 mmol/L). The time to swim 100 m after regeneration was 68.11 seconds, while that after rest was 69.31 seconds. Blood lactate levels rose by up to 78% after the intensity of the training sessions was progressively increased. Regeneration exercises increased the rate in which blood lactate dissipated, in comparison with passive recuperation. The rate of lactate dissipation for regeneration exercises was 68%. This factor may have improved the physical performance of swimmers. Regeneration exercises improved the performance of swimmers in maximal-exertion competition in a single day. The blood lactate level correlated with physical exercise load.

The relationship between the accumulation of lactate and a decrease in performance is documented. In the 1980s, methods were sought to increase clearance of blood lactate to decrease its deleterious effects on muscle metabolism. 9 Regeneration exercises (light training exercises) both in and out of the pool, massages, immersion in cold water, and other techniques were studied. Many of these methods decreased lactate, preventing its accumulation between competitions. 9,10,14
