Introduction: Due to the current COVID-19 pandemic, many countries have implemented control and prevention measures, such as compulsory lockdowns, affecting all spheres of life. Since the field of professional soccer is no exception, such measures may have a negative impact on the player’s well-being and their perceived training loads.
Objective: To determine the impact of COVID-19 lockdown measures on the training load and the well-being of female professional soccer players in Chile.
Materials and methods: Exploratory, cross-sectional, descriptive study conducted on 32 players of the Chile women’s national soccer team. The perception of training load and the level of well-being were assessed by means of the rating of perceived exertion (RPE) scale and a questionnaire developed in 2010, respectively. Both the administration of the questionnaire and the permanent monitoring of the RPE records were carried out in two periods of 12 weeks: regular preparatory phase (12/12/2019-10/03/2020) and lockdown (16/03/2020-07/06/2020). Data were analyzed using descriptive statistics and the Wilcoxon test was used to determine if there were significant differences between periods.
Results: Significant differences (p<0.05) and threshold effect sizes (ES)=1.2, 2.0 and 4.0 (large, very large, and extremely large, respectively) were found between both periods in all variables evaluated by the well-being questionnaire (except for sleep quality): muscle soreness and stress level (ES=1.9), perceived fatigue (ES=2.5), general well-being (ES=2.4), and mood (ES=4.2). No differences were found regarding the perception of the training load (ES=0.1) between both periods.
Conclusions: The level of well-being among the participants was negatively affected by the compulsory lockdown. Therefore, coaching staffs should continue to monitor the level of the well-being of professional soccer players during the lockdown, both individually and collectively. Even though the perception of training load was not affected, it is not possible to state that a more extended period of confinement will not reduce it, resulting in a drop in performance.
Introducción. Debido a la actual pandemia por COVID-19, muchos países tomaron medidas de control y prevención como el confinamiento obligatorio, afectando todas las esferas de la vida. Ya que los futbolistas profesionales no son una excepción, este tipo de medidas puede tener un impacto negativo en su bienestar y en su percepción sobre las cargas de entrenamiento.
Objetivo. Determinar los efectos de las medidas de confinamiento por COVID-19 en la carga de entrenamiento y el grado de bienestar de jugadoras de fútbol profesional de Chile.
Materiales y métodos. Estudio transversal, exploratorio-descriptivo realizado en 32 jugadoras de la Selección Nacional de Fútbol de Chile. El grado de bienestar y la carga de entrenamiento se evaluaron mediante un cuestionario desarrollado en 2010 y mediante la escala de percepción subjetiva del esfuerzo (PSE) y el volumen de entrenamiento expresado en minutos, respectivamente. Ambas evaluaciones se realizaron en 2 periodos de 12 semanas: periodo preparatorio regular (12/12/2019-10/03/2020) y periodo de confinamiento (16/03/2020-07/06/2020). Los datos se analizaron mediante estadística descriptiva y la prueba de Wilcoxon se utilizó para determinar si hubo diferencias significativas entre ambos periodos.
Resultados. Se encontraron diferencias significativas (p<0.05) y umbrales de tamaño del efecto (TE) iguales a 1.2, 2.0 y 4.0 (grande, muy grande y extremadamente grande, respectivamente) entre ambos periodos en todas las variables evaluadas por el cuestionario de bienestar (a excepción de calidad de sueño): dolor muscular y nivel de estrés (TE=1.9), fatiga percibida (TE=2.5), bienestar general (TE=2.4) y estado de ánimo (TE=4.2). No se observaron diferencias en la PSE (TE=0.1) entre ambos periodos.
Conclusiones. El confinamiento obligatorio afectó negativamente el grado de bienestar de las participantes, por lo que es necesario que los cuerpos técnicos monitoreen constantemente, de manera individual y colectiva, el grado de bienestar de los futbolistas profesionales durante estos periodos; si bien la percepción en la carga de entrenamiento no se vio afectada, no es posible asegurar que un periodo mayor de confinamiento no la disminuya y esto resulte en una baja del rendimiento.
