Abstract

Background: Participation in soccer training is beneficial for the development of energetic motor abilities and coordination abilities. The aim of this study was to evaluate the effect of closed-skill bodyweight resistance exercises which differ in their jumping movement structure, on jumping skills in youth soccer players. It was hypothesized that the examined exercises provide a better stimulus than soccer training for jumping development. Methods: Twenty-six young soccer players participated in the study. They were assigned to a strength training soccer group (SSG, n = 15) or a soccer group (SG, n = 11). The SSG realized a 9-week strength training in addition to soccer training. The following measurements were taken: countermovement jump with arm swing (CMJas), countermovement jump without arm swing (CMJ), an indicator of coordination of the upper limbs (CMJas – CMJ), and anaerobic power of CMJ (Pmax CMJ). Results: The obtained results showed similar improvements in jumping skills in both SSG and SG groups. Moreover, the results revealed a difference between both groups in pre- and post-training conditions for correlation coefficients observed between jumping variables. Conclusions: The strength exercises used in this study are not more beneficial for developing jumping skills than conventional soccer training among youth soccer players. Moreover, the strength training sessions should be based on a model of motor control in soccer players.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
