The purpose of this study was to examine differences in sports participation and the levels of physical activity (PA) and sedentary behaviour (SB) between schoolchildren with cystic fibrosis (CF) and a healthy control group (CG) taking into account the gender variable. PA and SB were measured with an accelerometer for 7 consecutive days in 44 children (24 girls; 11.0 (3.2) years) with CF and 45 age-, sex-, and socioeconomic status-matched controls (24 girls; 11.1 (3.0) years). CF patients and CG did not differ in moderate-to-vigorous PA (54 (31) vs. 59 (27) min/day respectively) or in SB (558 (106) vs. 553 (92) min/day respectively). There were no differences in meeting the PA guidelines between both groups (CF: 36.4% vs. CG: 42.4%). Gender analysis revealed that boys were more active and met more PA guidelines than girls regardless of the group (CF or CG), girls with CF being the least active group (only 16.7% met PA guidelines). A possible compensatory effect was found between SB and PA only in the CF sample, as for each minute/day spent in SB the odds of meeting PA guidelines decreased by 34%. These findings suggest that promoting a reduction in SB is as important as promoting PA in the CF population, especially in girls. Health caregivers, coaches, teachers, or parents could offer appealing supervised and unsupervised physical activities, foster the adoption of active lifestyles, or incorporate PA into daily routines to improve the health of CF schoolchildren.

El propósito del presente estudio es determinar la incidencia de lesión (frecuencia y gravedad) en el deporte del tenis, así como conocer qué tipo de lesiones tiene mayor influencia en los tenistas. La muestra se compone de 63 jugadores varones pertenecientes a clubes deportivos de la provincia de Alicante, con una media de edad de 31 años (d.t. 8,93). Se utilizó un diseño transversal y correlacional con una estrategia de recogida de datos selectiva mediante diseños de encuesta. Para evaluar las lesiones, se elaboró un registro de auto-informe. Los resultados indican que las lesiones más frecuentes en los tenistas son de tipo muscular afectando al hombro y a la pierna de leves a moderadas; tendinitis de hombro y de codo de leves a graves; y lesiones graves de esguince de tobillo. Por otro lado, el tiempo de práctica y la experiencia deportiva se relacionan con la frecuencia y con la gravedad de las lesiones. The intention of the present study is on the one hand, to determine what relation exists with the incidence of injury (frequency and severity) in tennis players; as well as to know what type of injuries has major influences. The sample was composed by 63 players men of tennis pertaining to Sport Clubs of the Province of Alicante, with an average of age of 31 years (d.t. 8,93). A cross-sectional and corelational design with a strategy of selective collection of data by means of survey designs was used. In order evaluate the injuries, an auto-report registry was elaborated. The results indicate that the most frequent injuries of the tennis players are muscular of shoulder and leg of slight to moderate, serious tendinitis of shoulder and elbow of slight to serious, and injuries of sprain of ankle; On the other hand, the time of practice and the sport experience are related to the frequency and with the injury severity, it is discussed on the relations of these variables, as well as on the applicability of the results and some conclusions of the study are indicated.
