The impact of physical exercise with additional visual tasks on UDVA and accommodation sensitivity in children: the mediating role of kinetic visual acuity.

Purpose: This study investigates the impact of physical exercise supplemented with visual tasks on children's uncorrected distance visual acuity (UDVA), kinetic visual acuity (KVA), and accommodative sensitivity, with an analysis of the mediating role of KVA.

Methods: A total of 168 third-grade students from four natural classes in a primary school in Suzhou City were randomly assigned to either an experimental group ( = 86) or a control group ( = 82). The experimental group engaged in 30 cycles of ciliary muscle training tasks with visual targets presented for 3 s during physical exercises, while the control group participated in regular physical exercises.

An experimental study on the influence of healthy physical education curriculum model on sports ability of Chinese senior high school students.

In recent years, the growing incidence of health issues among Chinese students, including obesity, diabetes, and other chronic diseases, has been attributed to a sedentary lifestyle, lack of physical activity, and unhealthy eating habits. Physical education (PE) classes play a crucial role in promoting physical activity and fostering healthy lifestyles among Chinese students. The purpose of this study was to investigate the influence of the healthy PE curriculum model on the sports ability of senior high school students in China.

Formulation of precise exercise intervention strategy for adolescent depression.

The high incidence of adolescent depression has become the focus of social and academic attention. Exercise is an important method to improve adolescent depression, but its intervention effect is still controversial. This study first compares and analyzes the relevant studies at home and abroad and finds that exercise prescription in adolescent depression intervention is not accurate enough.

The impact of additional visual tasks in physical exercise on balance ability among 9-10-year-old children: the mediating effect of visual acuity.

Purpose: This study aimed to explore the effects of additional visual tasks in physical exercise on the vision and balance ability of children, and to verify whether children's vision mediated the influence of physical exercise on their balance ability.

Methods: The study randomly selected 86 students aged 9-10 years old from a school in Suzhou city, dividing them into an experimental group ( = 43) and a control group ( = 43). The experimental group participated in physical exercise with additional visual tasks, while the control group engaged in routine physical exercise.

Arbuscular Mycorrhizal Fungi Can Inhibit the Allocation of Microplastics from Crop Roots to Aboveground Edible Parts.

Microplastics are emerging pollutants that threaten soil health and food safety. Recently, there has been increasing interest in understanding the behavior of these particles in the rhizosphere, specifically regarding the potential uptake of microplastics into crops. Arbuscular mycorrhizal (AM) fungi are widespread soil fungi, forming symbiotic associations with most terrestrial plants.

Effects of physical activity combined with different visual target presentation durations of ciliary-muscle training on visual acuity in children.

Purpose: This study aimed to identify the effect of different durations of visual target presentation during ciliary-muscle training on children's kinetic visual acuity (KVA), uncorrected distance visual acuity (UDVA), axial length, and accommodative facility.

Methods: Based on the ciliary-muscle regulation mechanism, an intervention program involving ciliary-muscle training with different durations of visual target presentation combined with physical education classes was designed. The intervention aimed to determine the effect of different ciliary-muscle training durations on children's visual acuity.

Arbuscular mycorrhizal symbiosis alleviates ozone injury in ozone-tolerant poplar clone but not in ozone-sensitive poplar clone.

Tropospheric ozone (O) is a typical air pollutant with harmful effects on plants, whereas arbuscular mycorrhizal (AM) fungi are ubiquitous plant symbionts that enhance plant resistance to various abiotic stresses. However, whether AM symbiosis decreases plant O sensitivity and what the underlying mechanisms are remain unclear. In this study, O-tolerant poplar clone 107 and O-sensitive poplar clone 546 were used as test plants.

Effect of physical activity combined with extra ciliary-muscle training on visual acuity of children aged 10-11.

This study is intended for exploring the effects of the physical activity combined with extra ciliary-muscle training with different frequencies on children's kinetic visual acuity and uncorrected distance visual acuity, and eventually figuring out the optimal frequency of ciliary-muscle training for each physical education class. To do the present research, A total of 160 students aged 10-11 from a school in Suzhou (a major city located in southeastern Jiangsu Province, East China) were randomly selected and divided into control group ( = 33), 15-frequency group ( = 44), 30-frequency group ( = 40) and 60-frequency group ( = 43), and the latter three experimental groups participated in a specially designed physical activity plan based on the training principles of ciliary muscle, while the control group participated in normal physical activity as usual. The experimental intervention period was 16 weeks, and all students' kinetic visual acuity and uncorrected distance visual acuity were measured before and after the experiment.

Long-term nickel contamination increased soil fungal diversity and altered fungal community structure and co-occurrence patterns in agricultural soils.

Nickel (Ni) contamination imposes deleterious effects on the stability of soil ecosystem. Soil fungal community as a crucial moderator of soil remediation and biochemical processes has attracted more and more research interests. In the present study, soil fungal community composition and diversity under long-term Ni contamination were investigated and fungal interaction networks were built to reveal fungal co-occurrence patterns.

Ozone does not diminish the beneficial effects of arbuscular mycorrhizas on Medicago sativa L. in a low phosphorus soil.

Enriched surface ozone (O) can impose harmful effects on plants. Conversely, arbuscular mycorrhizal (AM) symbiosis can enhance plant tolerance to various environmental stresses and facilitate plant growth. The interaction of AM fungi and O on plant performance, however, seldom has been investigated.

Functional traits of poplar leaves and fine roots responses to ozone pollution under soil nitrogen addition.

Concurrent ground-level ozone (O) pollution and anthropogenic nitrogen (N) deposition can markedly influence dynamics and productivity in forests. Most studies evaluating the functional traits responses of rapid-turnover organs to O have specifically examined leaves, despite fine roots are another major source of soil carbon and nutrient input in forest ecosystems. How elevated O levels impact fine root biomass and biochemistry remains to be resolved.

Interactive effects of ozone exposure and nitrogen addition on tree root traits and biomass allocation pattern: An experimental case study and a literature meta-analysis.

Ground-level ozone (O) pollution often co-occurs with anthropogenic nitrogen (N) deposition. Many studies have explored how O and soil N affect aboveground structure and function of trees, but it remains unclear how belowground processes change over a spectrum of N addition and O concentrations levels. Here, we explored the interactive impact of O (five levels) and soil N (four levels) on fine and coarse root biomass and biomass allocation pattern in poplar clone 107 (Populus euramericana cv.
