“…Meanwhile, an increase in AQI would likely bring a small increment in the physical performance-related parameters and would most unlikely bring a decrease. At the same time, this result is also contrary to the previous findings [39], which demonstrated that air pollution would decrease the physical performance of soccer players. These divergences can be explained by the difference in the amount of pollutant administered or the nature of exercise protocols.…”

To investigate the effects of situational factors (match location, strength of team and opponent) and environmental factors (relative air humidity, temperature and air quality index) on the technical and physical match performance of Chinese Soccer Super League teams (CSL). The generalized mixed modelling was employed to determine the effects by using the data of all 240 matches in the season 2015 collected by Amisco Pro®. Increase in the rank difference would increase the number of goal-scoring related, passing and organizing related actions to a small-to-moderate extent (Effect size [ES]: 0.37–0.99). Match location had small positive effects on goal-scoring related, passing and organizing related variables (ES: 0.27–0.51), while a small negative effect on yellow card (ES = −0.35). Increment in relative air humidity and air quality index would only bring trivial or small effects on all the technical performance (ES: −0.06–0.23). Increase in humidity would decrease the physical performance at a small magnitude (ES: −0.55–−0.38). Teams achieved the highest number in the physical performance-related parameters at the temperature between 11.6 and 15.1 °C. In the CSL, situational variables had major effects on the technical performance but trivial effects on the physical performance, on the contrary, environmental factors affected mainly the physical performance but had only trivial or small impact on the technical performance.

“…To some extent, associations between CBC parameters and pollution exposure could be clari ed. Experimental and epidemiological studies indicate that exposure to air pollutants is negatively associated with RBC, HCT, and Hgb [13][14][15]. An animal experimental study [16] indicated that mediumterm exposure to air pollutants decreases RBC and monocytes and increases lymphocytes.…”

BackgroundShanghai Chemical Industry Park (SCIP), located in Jinshan District, is the largest industrial zone in China. However, the impact on the residents’ health has not been assessed. The study aimed to identify the impact of living in chemical industrial areas on the health of first-grade studentsMethodA cross-sectional study was conducted among first-graders between May and June 2016 in Jinshan District using experimental examinations and questionnaires. Demographic statistics and hematological parameters were summarized. Geographical distribution and high-risk clusters of prevalence of diseases and birth status were depicted. Multivariate logistic model was used to analyze the differences in the prevalence of diseases and symptoms between chemical and nonchemical industrial areas after adjusting for potential factors.ResultA total of 4821 first graders were included in the study. Mean age was 7.2 (±0.41) years. The prevalence of respiratory, digestive, and skin diseases was 0.229, 0.042, and 0.168, respectively. We observed one spatial cluster each for respiratory diseases (RD) and skin diseases, respectively. Significant differences in birth defects were not observed. Some significantly different hematological parameters and higher prevalence of RD in nonchemical industrial areas might indicate pollutant exposures in nonchemical industrial areas. The study revealed a possible positive association between environmental factors and RD.ConclusionStrong evidence regarding the main impact of SCIP on the health of school children was not observed. Governments and parents might need to pay more attention to indoor and other environmental management. Long-term health effects of chemical industries should be continuously monitored.

“…In the literature, it was observed that body temperature was higher in the evening than in other hours of the day (Hammouda et al, 2012;Jaraya et al, 2014;Konishi et al, 2016;Ozcelik and Guvenc, 2016;Boussetta et al, 2017). Reilly and Garrett (1998) reported that rectal temperature was 0.68 0 C lower in the morning than in the evening hours.…”

“…Similar vertical jump score was found in this study. In a study conducted Boussetta et al, (2017) on 11 football players with a mean age of 21.8, the results revealed that diurnal variation was found in short-term maximal tests (vertical jumping test). The vertical jump height was reported to be significantly better in the evening hours.…”

“…This positively affected the swimming performance. Boussetta et al (2017) and Hammouda et al (2012) stated that Yo-Yo Intermittent-1 test soccer players (mean age: 21.8) were found to be better in evening hours than in the morning hours Heart Rate and Blood Lactate Level after tests Statistically significant differences were observed when comparing heart rate F(2,18)=6,859, p<.006), and blood lactate levels after the tests (F(2,18)=6,041, p<.01) measured at morning (09.00-10.00), afternoon (12.00-13.00) and evening time periods (16.00-17.00). The heart rate and blood lactate levels of athletes after tests were found to be 6.57% and 44.82% significantly higher in the evening hours, respectively (Table 4).…”

The aim of this study was to examine the time of day effect on aerobic capacity, repeated sprint ability and physiological responses in team-sport athletes. Ten male athletes (age: 21.60 ± 1.42, height: 185.10 ± 7.30cm, body weight: 82.15 ± 4.88, % body fat: 12.98 ± 2.39) who regularly exercise and engage in team sports, participated in this study voluntarily. Athletes were subjected to Repeated Anaerobic Sp rint Test and 20m Shuttle Run Test at three different times of the day in the morning (09.00-10.00), afternoon (12.00-13.00) and evening (16.00-17.00) at two-day intervals. As a result of Repeated M easures ANOVA, statistically significant differences were observed when comparing body temperature (F(2,18)=10.042, p=.001), vertical jump height (F(2,18)=9.216, p=.005), maximal power (F(2,18)=9.059, p=.002), mean power (F(2,18)=8.617, p=.002), minimum power (F(2,18)=7.120, p=.002), aerobic capacity (F(2,18)=6.967, p=.006), maximal heart rate F(2,18)=6.859, p=.006), and blood lactate levels after exercise tests (F(2,18)=6.041, p=.010) measured at morning, afternoon and evening time periods. According to Bonferroni test results; body temperature, vertical jump height, maximal power, aerobic capacity values were found to be statistically higher in the evening hours than the morning hours (p<0.05). Blood lactate level and maximal heart rate were increased significantly after tests in the evening (p<0.05). In this study, factors such as having a good sleep quality, body temperature and circadian type can be shown as reasons for the performance of the athletes to be good in the evening compared to the morning hours. In conclusion, while planning the athletic training programs, it is thought that it is important to perform training which include aerobic and anaerobic capacity, explosive power and jumping exercises in the evening hours because of the significant increases in performance of the athletes
