Contextual interference effects on volleyball serve acquisition: a controlled trial with physical-education majors.

To address limitations in previous domestic and international studies on "the effect of background interference on volleyball learning", the present study selected 60 students majoring in physical education from the 2021 class at Qufu Normal University as experimental subjects to examine their skill acquisition. This study aimed to explore the differential effect of background interference on the learning of volleyball serving technique of students majoring in physical education. During an 8-week teaching experiment, the effects of three training modes, namely group block practice (low interference), mixed practice (medium interference), and random practice (high interference), on the learning effect of the serving technique of 60 physical education majors were compared.

Seasonal Variations in the Structure and Function of the Gut Flora in Adult Male Rhesus Macaques Reared in Outdoor Colonies.

The seasonal variations that occur in the gut microbiota of healthy adult rhesus monkeys kept in outdoor groups under conventional rearing patterns and how these variations are affected by environmental variables are relatively poorly understood. In this study, we collected 120 fecal samples from 30 adult male rhesus monkeys kept in outdoor groups across four seasons and recorded the temperature and humidity of the housing facilities, as well as the proportions of fruit and vegetables in their diet. A 16S rRNA sequencing analysis showed that the alpha diversity of the gut microbiota of the rhesus monkeys was higher in winter and spring than in summer and autumn.

Perspective on using non-human primates in Exposome research.

The physiological and pathological changes in the human body caused by environmental pressures are collectively referred to as the Exposome. Human society is facing escalating environmental pollution, leading to a rising prevalence of associated diseases, including respiratory diseases, cardiovascular diseases, neurological disorders, reproductive development disorders, among others. Vulnerable populations to the pathogenic effects of environmental pollution include those in the prenatal, infancy, and elderly stages of life.
