“…Also, there was no significant time-of-day effect for the other mood parameters and there were no-significant correlations between the psychological parameters and performance. Therefore, the present study does not support the speculation of Chtourou et al (2014) but rather indicates that diurnal variation of soccer specific-skills is not associated with fluctuations in children's mood states.…”

“…The present study showed that RPE scores (the sensation of exertion) were higher in the afternoon (when there was better performance and a greater TT) than in the morning, and this might be used to increase the amount of activity undertaken in the afternoon by children (Chtourou et al, 2014) of fatigue and might be influenced by the psychological state of the participant (Foster et al 2001). …”

“…during squat jumps, countermovement jumps and a 30-s cycling test) were significantly higher in the afternoon (17:00 h) than the morning (07:00 h). Also, Chtourou et al (2014) showed that, in children, squat jumps and countermovement jumps were performed better at 14:00 h and 18:00 h than at 08:00 h. Moreover, they reported that maximal aerobic velocity during the Yo-Yo intermittent recovery test was higher at 18:00 h than 08:00 h. The discrepancies between the results of the present study and those of Reilly et al (2007) might arise because children's maximal voluntary contraction, contractile velocity and muscle power are lower compared to adults, and there is a higher degree of agonist-antagonist co-contraction in children (Dotan et al 2012). Chtourou et al (2014) speculated that this time-of-day effect on performance could be related to changes in a child's mood during the day.…”

“…These studies of Reilly et al (2004aReilly et al ( , b, 2007 have focused on adult soccer players and these results are not applicable for children as there are some differences in their physical, mental and psychological abilities -for example, time-of-day effects on performance in children could be affected by their mood during the day (Chtourou et al 2014). …”

The aim of the present study was to examine the effect of time-of-day on soccer specific skills and physiological and psychological parameters in children. Ten male children soccer players (age: 14.6 ± 0.8 years; height: 1.63± 0.4 m; body-mass: 52.5 ± 4.9 kg) performed two shooting accuracy tests before and after a 10 × 20-m dribbling sprint test with 20-s of passive recovery between repetitions. The measurements were taken at 08:00h, 13:00h and 17:00h in a randomized order. Mean heart rate (HR) was monitored during the dribbling test. At the beginning of each test session, blood pressure and intra-aural temperature were measured.Likewise, children were asked to complete the profile of mood state (POMS) and the Hooper Index questionnaires. Lactate concentration ([La]) was recorded at rest, post-fifth recovery periods and post-second accuracy test. Moreover, they indicate their rating of perceived exertion score (RPE) immediately at the end of each test session. The results of the present study showed that dribbling performance was higher at 13:00h and 17:00h in comparison with 08:00h (p<0.05). Likewise, intra-aural temperature, RPE scores, depression recorded by the POMS questionnaire and the stress recorded by the Hooper questionnaire were higher in the afternoon (p<0.05). However, the fatigue during the 10 × 20-m dribbling sprint and the kicking accuracy were not affected by the time-of-day. Moreover, [La], mean HR, systolic blood pressure and diastolic blood pressure were not affected by the time-of-day. For the correlations analysis between all parameters, the statistical analysis showed significant correlation only between TT and RPE scores and between MT and RPE scores (r=0.6, p<0.05). In conclusion, shooting accuracy was not affect by the time-of-day. However, dribbling performance of children is better in the afternoon than the morning. This diurnal variation could not been explained by variation in mood or in [La], mean HR, systolic blood pressure and diastolic blood pressure.

“…One possible limitation for the present study was that the time of day of measurement was not taken into account. As previous studies have reported that physical and cognitive performance of children is dependent on time-of-day [39][40][41][42][43], further studies are needed to assess the physical fitness at the same daytime and during the same season.…”

Underweight and overweight are serious health concerns for many children and could be associated with low physical-fitness levels. This study aimed (i) to evaluate the prevalence of underweight and overweight and (ii) to examine its association with the physical fitness levels in primary male and female schoolchildren. Including 13 government primary-schools, a cross-sectional survey was conducted between 2014 and 2017. Anthropometric characteristics together with the physical-fitness level were measured in 931 schoolchildren aged between 6- and 11-years old. The prevalence of under- and overweight children were 8.49% and 24.06%, respectively. These proportions were not significantly different between males and females and were affected by age (p < 0.001), with a higher prevalence of overweight and a lower prevalence of underweight at 9–11 years, compared to 6–8 years old. Concerning the physical fitness levels, statistical analysis showed a better performance among males compared to females, among participants aged 9–11 years, compared to 6–8 years old, and among underweight and normal-weight, compared to overweight children (p < 0.001). There was a higher prevalence of overweight and lower prevalence of underweight at 9–11 years compared to 6–8 years old. Physical fitness levels were better in (i) males, compared to females, (ii) schoolchildren aged 9–11 years, compared to 6–8 years old, and (iii) underweight and normal-weight, compared to overweight children.
