The objective of the present study is to analyze the effects of motor mental imagery training on tennis service performance among tennis athletes who fast during Ramadan. Participants were 38 young male tennis players, randomly divided into two groups: Imaging Training (IMG, = 18) and control group (CG, = 20). The CG has watched videos on the history of the Olympic Games, while IMG has followed a training program in motor imagery. The performance of the tennis service was obtained by the product between accuracy and speed of typing (accuracy x average speed of all shots (km/h)). The effect of group / time interaction ( < 0.01) was identified for all performance indicators (accuracy, running speed and performance (speed x precision)), with improvement only in IMG ( = 0.01). The results showed that motor imagery training could be an effective strategy for mitigating/counteracting the negative effects of Ramadan on the tennis service performance.

The purpose of this study was to explore the experiential knowledge of tennis coaches as it related to the development of grip positions in tennis athletes. Accredited tennis coaches (n = 11) completed semi-structured interviews consisting of open-ended questions about their coaching background, the importance of grip positions compared with other areas of foundational development, and their opinions on using physically-constraining tools (PCTs). Two major themes, "Grip positions are an adaptive skill" and "Why and how do I modify an athlete's grip?", were identified.

Unlabelled: Long-term training induces neural plasticity in the visual cognitive processing cortex of table tennis athletes, who perform cognitive processing in a resource-conserving manner. However, further discussion is needed to determine whether the spatial processing advantage of table tennis players manifests in the early stage of sensory input or the late stage of processing. This study aims to explore the processing styles and neural activity characteristics of table tennis players during spatial cognitive processing.

Modern tennis forehand grip style and ball contact points have evolved to enhance power and topspin. Different grip styles and ball contacts are recommended; however, little data are available to support one over another. Through a quantitative experimental study, we sought to determine which grip style and ball contact point produced the greatest forces at static contact.

Pathogenic variants in either the mitochondrial or nuclear genomes are associated with a diverse group of human disorders characterized by impaired mitochondrial function. Within this group, an increasing number of families have been identified, where Mendelian genetic disorders implicate defective mitochondrial RNA biology. The PDE12 gene encodes the poly(A)-specific exoribonuclease, involved in the quality control of mitochondrial non-coding RNAs.

Clinical findings are generally sufficient to make the diagnosis of lateral epicondylitis of the elbow. Ultrasound (US), in conjunction with standard radiography, is a simple and cost-effective way to confirm the diagnosis, and it is also useful for eliminating most differential diagnoses and guiding treatment.US analysis of the muscle bodies and tendon laminae of the lateral epicondyle muscles, starting distally at the wrist and extending up to the lateral epicondyle, assists in understanding the complex fibrous architecture of the proximal tendons inserting on the lateral epicondyle.
