Introduction: The use of functional strength training in running training allows athletes to produce a continuous development behavior improving their various functional and competitive abilities. Objective: Study the effect of functional training on the physical quality of runners in track and field. Methods: Six athletes were selected whose changes in parameters of the technical index of the hurdle stage before and after training were analyzed to explore the influence of functional training on the specific technique of the hurdle stage. Results: In the fitness test items of the 6 athletes, the performances of 30 meters, 100 meters, triple standing jump, and backward ball throw were increased by 0.02 seconds, 0.09 seconds, 0.09 meters, and 0.20 meters, respectively, compared to the average before training. An average improvement of 2.50 points was shown in functional movement screening scores. Conclusion: Functional training can improve the physical quality of athletes, positively helping athletes’ obstacle course running performance. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

“…Earthworms are a diverse group of the soil macro fauna that serve important roles in recycling nutrients, improving hydraulic conductivity and facilitating the assimilation of organic matter by other soil organisms (Bhadauria & Saxena, 2010;Marinissen & Ruiter, 1993;Scheu, 1987;Wen et al, 2020). Considering their large biomass, they are dominant organisms within the soil compartment (Lavelle & Spain, 2002;Medina-Sauza et al, 2019) and aggregate underneath dung pats (Bacher et al, 2018(Bacher et al, , 2020. These localized "hotspots" provide increased opportunity for interactions between earthworms and animal parasitic nematode communities that are present within the dung compartment.…”

Gastrointestinal helminth parasites undergo part of their life cycle outside their host, such that developmental stages interact with the soil and dung fauna. These interactions are capable of affecting parasite transmission on pastures yet are generally ignored in current models, empirical studies and practical management. Dominant methods of parasite control, which rely on anthelmintic medications for livestock, are becoming increasingly ineffective due to the emergence of drug‐resistant parasite populations. Furthermore, consumer and regulatory pressure on decreased chemical use in agriculture and the consequential disruption of biological processes in the dung through nontarget effects exacerbates issues with anthelmintic reliance. This presents a need for the application and enhancement of nature‐based solutions and biocontrol methods. However, successfully harnessing these options relies on advanced understanding of the ecological system and interacting effects among biotic factors and with immature parasite stages. Here, we develop a framework linking three key groups of dung and soil fauna—fungi, earthworms, and dung beetles—with each other and developmental stages of helminths parasitic in farmed cattle, sheep, and goats in temperate grazing systems. We populate this framework from existing published studies and highlight the interplay between faunal groups and documented ecological outcomes. Of 1756 papers addressing abiotic drivers of populations of these organisms and helminth parasites, only 112 considered interactions between taxa and 36 presented data on interactions between more than two taxonomic groups. Results suggest that fungi reduce parasite abundance and earthworms may enhance fungal communities, while competition between dung taxa may reduce their individual effect on parasite transmission. Dung beetles were found to impact fungal populations and parasite transmission variably, possibly tied to the prevailing climate within a specific ecological context. By exploring combinations of biotic factors, we consider how interactions between species may be fundamental to the ecological consequences of biocontrol strategies and nontarget impacts of anthelmintics on dung and soil fauna and how pasture management alterations to promote invertebrates might help limit parasite transmission. With further development and parameterization the framework could be applied quantitatively to guide, prioritize, and interpret hypothesis‐driven experiments and integrate biotic factors into established models of parasite transmission dynamics.

The capacity of nano-zero-valent iron (nZVI) and soil animals to remediate heavy metal–contaminated soil has been widely studied. However, the synergistic effect of soil animals and nZVI has not been thoroughly investigated. Here, we studied the combined effect of earthworms and nZVI on soil physicochemical properties and microecology during remediation of cadmium (Cd)–contaminated soil. The results showed that although amendment with nZVI reduced earthworm survival and biomass, the combination of nZVI and earthworms was effective at reducing the available Cd (ACd) content of soil and improving its quality. ACd most effectively reduced by 75.3% in the presence of earthworms under the 0.25% nZVI combination. Meanwhile, the combined action of earthworms and nZVI significantly improved soil properties and increased the diversity of soil microorganisms. In the earthworm-free system, nZVI reduced ACd by increasing soil pH and the abundance of Stenotrophobacter in Cd-contaminated soil, in addition to the co-precipitation and adsorption reported in previous studies. Correlation analysis revealed that the combination of nZVI and earthworms synergistically decreased ACd by decreasing soil OM and increasing the relative abundance of Opitutus and Gemmatta. Overall, our study indicates that the combination of nano-zero-valent iron and earthworms is a potential system for in situ remediation of Cd-contaminated soils and provides a deep understanding of the mechanisms involved in remediation.
