Título: Relationship between injury risk, workload, and rate of perceived exertion in professional women's basketball
Fuente: Apunts, Med. esport (Internet);55(206):71-79, abr.-jun. 2020. tab.
Idioma: es.
Resumen: In order to better understand the possible relationships between the application of training loads and the risk of injury in professional women's basketball, four parameters from a professional women's basketball team (N = 11) were analysed: exposure time, number of injuries, rate of perceived exertion (RPE), and workload (sRPE). A total of 3182h of exposure were registered, 2774 were training hours, and 408 were game hours with a total of 9 time loss injuries. The data obtained from each player was related to the exposure time, injury risk, perception of effort, and workload. Several differences were observed between the injury risk values and the morning RPE (F = 5.0811; p = .032), the sRPE of the morning practices (F = 7.3585; p = .010) and the total time of exposure (F = 3.5055; p=.064). There is also a significant negative relationship between total training time and the number of time-loss (TL) injuries (rho = - .797; p = .003), as well as a possible association between exposure time and a lower risk of TL injury (R2 = .645). These findings suggest that an increase in specific exposure time could be associated with a decrease in the risk of time-loss injuries

Con el objetivo de entender mejor las posibles relaciones entre la aplicación de cargas de entrenamiento y el riesgo de lesión en el baloncesto femenino profesional, se analizaron 4 parámetros de un equipo de baloncesto femenino profesional (N = 11): tiempo de exposición, número de lesiones, percepción del esfuerzo después de las sesiones entrenamiento (RPE) y carga de entrenamiento (sRPE). Se registraron 3.182 horas de exposición totales, de las cuales 2.774 fueron de entrenamiento y 408h de competición con un total de 9 lesiones "time-loss" (TL) que comportaron tiempo de actividad perdido. Se relacionan los datos obtenidos de cada jugadora relativos a tiempo de exposición, lesiones, percepción del esfuerzo y carga de trabajo. Se observan posibles diferencias entre los valores de lesionabilidad y RPE de las sesiones de entrenamiento de la mañana (F = 5,0811; p = 0,032), el sRPE de la mañana (F = 7,3585: p = 0,010) y el tiempo total de exposición (F = 3,5055; p = 0,064). Se observa también una relación significativa negativa entre tiempo total de entrenamiento y el número de lesiones TL (rho = -0,797; p = 0,003), así como una posible asociación entre el tiempo de exposición y una menor incidencia lesional TL (R2 = 0,645). Estos valores sugieren que un aumento del tiempo de exposición de carácter específico podría vincularse a la disminución del riesgo de lesiones "time-loss"

Título: Observational study with the objective of determining possible correlations between GRF and muscle activation at reception after a jump in an ACL injury
Fuente: Apunts, Med. esport (Internet);55(206):63-70, abr.-jun. 2020. tab, graf.
Idioma: en.
Resumen: INTRODUCTION: The ACL injury is considered one of the most serious injuries and usually occurs in actions that include movements with changes of direction, jump and landing. It is a common injury between the young active population and the risk in women of suffering from non-contact injury is superior to that of men. Athletes who suffer from non-contact injuries of the ACL usually have common biomechanical profiles, with landings with large values in ground reaction force (GRF) and therefore, low cushioning on landing. OBJECTIVE: To determine possible correlations between GRF and muscular activation at lading after a jump. MATERIAL AND METHODS: The type of study carried out is an observational study in which, using surface electromyography (EMG), a force platform and an electrogoniometer, the aim is to assess muscle activation and its relationship with GRF (specifically the vertical component Fz). RESULTS: Correlations have been observed between the reaction force of the soil (Fz) in the moments where the reaction force of the soil is greater and the instant where the knee reaches maximum flexion after landing, with the activation of certain muscle groups and differences depending on the gender of the subject. DISCUSSION: The neuromuscular recruitment strategies in the phases of maximum GRF load and knee flexion are different depending on the sex of the individual, so it should be considered when scheduling prevention and recovery work. CONCLUSION: The evaluation of GRF and muscle activation patterns, allows to assess the dynamics of landing after a jump and to be able to detect different patterns according to sex, with the consequent importance that it can have in the injury mechanism

Resumen: This study examines the effects of two strength training (ST) programs, one based on mean propulsive velocity (MPV) and another under the traditional method, the % one-repetition maximum (1RM), on neuromuscular performance and muscle composition in girls who play soccer. Fifty players with an average age of 13.6 ± 1.2 years participated in the study and were randomly assigned into three groups: a maximal execution velocity training group (VG, n = 15), a maximal strength group (RMG, n = 13), and a control group (CG, n = 18). The study was developed for a period of twelve weeks during regular team training to prepare for the season. The VG and RMG groups performed additional strength or muscle power training three times a week, including movements of full squat and pedaling on a cycle ergometer. The two types of training groups and the control group exhibited significant gains. However, the greatest increases were achieved with VG training, with significant increases (p < 0.000) in maximal strength, (p < 0.000) squat power, (p < 0.000) velocity over 30 m, (p < 0.000) cycle ergometer power, and (p < 0.008) lower limb muscle mass. Statistically significant differences were observed between VG and RMG in countermovement jump (CMJ) (p < 0.008) and squat power (p < 0.01) tests, between VG and CG in CMJ (p < 0.01), squat power (p < 0.000), and maximal squat strength (p < 0.000), and between RMG and CG in maximal squat strength (p < 0.000) only. These findings might indicate that high-velocity ST can be performed simultaneously with regular training to improve the explosive actions of soccer players

Título: Associations between obesity, asthma and physical activity in children and adolescents

Resumen: Obesity and asthma have increased in prevalence dramatically among children and adolescents. There is strong epidemiological evidence of an association between these chronic morbidities, suggesting many pathophysiological pathways which may play a role in this association such as adipokines, oxidative stress, physical activity, comorbidities and diet. Physical activity and exercise are recommended to reduce obesity and the risk of several diseases. However, exercise is a common trigger of asthma, known as exercise-induced bronchoconstriction. Similarly, obesity-related physical deconditioning may also lead to dyspnoea and exercise limitation which can mimic asthma symptoms. Furthermore, to confirm that excessive weight is a risque factor for asthma, the evidence of causality must establish whether weight loss should decrease in asthma symptoms. The purpose of this review is to summarize what is known about the complex relationship between obesity, asthma and physical activity

Resumen: INTRODUCTION: The aim of these studies was to evaluate the effects of regular volleyball training on salivary SIgA and alpha-amylase in female children and adolescents. MATERIAL AND METHOD: In the cross-sectional study, 115 female children (12.6 ± 2.2 years) participating in a Volleyball training program were classified as beginners, intermediate, and competitive level. The children were evaluated regarding caries index, body mass index (BMI), cardiorespiratory fitness, and countermovement jump. In the longitudinal study: 54 girls (intermediate and competitive groups) trained for 8 weeks and were re-evaluated at weeks 4 and 8. RESULTS: The SIgA secretion rate and alpha-amylase activity did not present correlations with training category, age, caries index, or training status. A weak positive correlation was detected between IgA secretion rate and BMI (r = 0.20, p < 0.05). After 8 weeks of training, VO2max (p < 0.005) and jump height (p < 0.005) improved in the competitive girls. No differences were observed in salivary secretion rate, SIgA concentration and secretion rate, or alpha-amylase activity at weeks 4 and 8. CONCLUSIÓN: We concluded that despite improving physical fitness, 8-weeks of recreational volleyball training are not able to improve salivary SIgA secretion or alter alpha-amylase activity in female children and adolescents

Resumen: INTRODUCTION: The present study was to determine the effect of 8-week of the concurrent exercise training on Murf-l and Atrogin-1 Gene Expression of the vastus lateralis muscle in male Wistar rats. MATERIAL AND METHODS: This study was conducted as an experimental project consisting of four groups of 35 two-month-old male Wistar rats. The animals were randomly divided in 4 groups: (1) endurance training, (2) resistance training, (3) combined training, and (4) control. The animals in the training groups took part in training programs for 8-week. 48h after the last exercise session, the Murf-1 and Atrogin-1 genes of the vastus lateralis muscle were examined through the use of qPCR method. RESULTS: The results obtained from this study revealed that after 8-week of endurance exercise, Murf-1 and Arogin-1 gene expression significantly increased compared to the control group (p = 0.04 and p = 0.043). In contrast, in the resistance training group, the gene expression of Murf-1 and Atrogin-1 decreased significantly in comparison with the control group (p = 0.02 and p = 0.04). In addition, the concurrent training group showed no difference in Murf-1 and Atrogin-1 gene expression after 8-week of exercise compared to that of the control group (p = 0.43 and p = 0.38). CONCLUSIONS: Based on the results of the present research, it can be expressed that resistance training prevents muscular atrophy by decreasing Murf-1 and Atrogin-1 gene expression. Conversely, endurance exercises cause an increase in the expression of these genes, thereby leading to atrophy in the muscles. The results also showed that concurrent exercises do not have a meaningful effect on muscular atrophy

Resumen: Femoroacetabular impingement (FAI) is a common injury in basketball, having a difficult therapeutic approach because it requires an extended period of time to be resolved once it appears. Therefore, preventing the onset of this condition seems critical in maintaining athletes' health, and availability to compete. Because reducing training and competition volume in a professional team context is complex, the exercises presented here offer a good option for managing injured players without compromising their availability during the season. However, offseason and preseason periods are key to developing, protecting and strengthening the injured joint and its functionality for the competitive season

Resumen: The spread of CoV-2 occurs mainly by respiratory droplets. Its dispersion depends on several factors: viscoelasticity of fluid, ventilation, evaporation rate, exhalations, sneeze or cough. At moment, the preventive distance to avoid the contamination has been established in 1-2 m. We believe that it is necessary to review this aspect, because the respiratory flows change with the intensity of physical activity. The ventilatory response can be evaluated in terms of ventilatory demand or ventilatory efficiency. During maximal effort tests, athletes mobilize an extraordinary amount of air arriving to 150/200 L/min. The respiratory volume follows increase in linear progression during the test in function of power developed. When the air volume is increased 10 times, we think that the distance should be around 6-7 m
