Do Different Playing Formats and Aerobic Capacity Influence Variances in Psychophysiological Demands and Technical Performance in Small-Sided Games? A Study among Under-17 Male Soccer Players.

This study aimed to: (i) analyze the variations in psychophysiological demands (mean heart rate, meanHR; rate of perceived exertion, RPE) and technical performance (umber of successful and unsuccessful passes, and occurrences of ball loss) between 2v2 and 4v4 small-sided games (SSGs) formats, and (ii) examine the relationships of aerobic capacity measured in Yo-Yo Intermittent Recovery Test (YYIRT) on psychophysiological and technical performance during SSGs. This study used a cross-sectional design with repeated measures, where the same players participated in both 2v2 and 4v4 formats across two training sessions per format. Twenty-four talent/developmental male youth soccer players, aged 16.

Using the Paired Sample t test to Analyze the Effect of Jogging on the Cardiovascular Function of College Students.

Background: In China, there have been instances of sudden cardiac death among university students, with a significant number of students being at risk of cardiovascular diseases. This risk is often attributed to sub-health conditions such as weight gain and obesity, which are triggered by sedentary lifestyles, irregular living habits, and unregulated diets. Therefore, it is crucial to enhance the guidance for participation in physical activities, encouraging students to actively reduce their risk of cardiovascular diseases (CVD).
