Chapter Summaries

Background: This chapter introduces the concept of shoulder loading position (SLOP) in the tennis serve and its importance in the kinetic chain. It highlights the role of ground reaction forces and energy transfer from the lower limbs to the upper limbs. The chapter emphasizes individual variations in serve motion and the lack of knowledge regarding the association between SLOP and manually influenced eye dominance (MIED). It states the study's aim to investigate this association, particularly focusing on circular MIED (C-MIED) due to its relevance to the tennis racket grip. The existing literature gap concerning hand-eye coordination and its influence on the tennis serve is also discussed.

Methods and materials: This chapter details the methodology employed in the study. It describes the selection of participants (31 right-handed tennis players), the use of an eight-camera VICON system for SLOP evaluation, and the definition of SLOP as closed (≥90°) or open (<90°). The chapter outlines the two eye dominance tests used (Porta Test and Circular Test) and explains the comparative analyses performed to investigate the relationship between SLOP and MIED. The ethical considerations and approvals obtained are also mentioned. The chapter explains the process of comparing SLOP results with previously obtained MIED data (Study I).

Results: This chapter presents the findings of the study. It reports that the closed SLOP was the most common (n=22; p=0.02). The comparative analysis of SLOP with the Porta Test MIED (P-MIED) and Circular Test MIED (C-MIED) revealed significant differences. A greater number of players with closed SLOP displayed crossed C-MIED compared to crossed P-MIED. The statistical significance (p-values) of these comparisons and their interpretation are detailed, highlighting differences in the association between SLOP and the two types of MIED. The chapter summarizes the key statistical findings related to the relationship between SLOP and both eye dominance tests.

Discussion: This chapter interprets the results in the context of existing literature. It discusses the implications of the findings regarding the relationship between MIED and SLOP in the tennis serve. The chapter likely explores the reasons for the observed differences between P-MIED and C-MIED in relation to SLOP, potentially considering factors such as the biomechanics of the serve and the nature of the eye dominance tests. The practical implications of the findings for tennis coaching and player development are also likely discussed.

Strengths and limitations: This chapter assesses the strengths and limitations of the study. The strengths might include the use of advanced technology (VICON system), the rigorous methodology, and the inclusion of both P-MIED and C-MIED analyses. Limitations might include the sample size, the specific characteristics of the participant population, and the potential for bias in the measurements or data interpretation. The chapter critically evaluates the methodology and considers potential sources of error or limitations in the generalization of the findings.

Future perspective: This section outlines directions for future research. It may suggest further investigation into the relationship between MIED and SLOP in different populations of tennis players or in other sports. It might also propose the use of alternative measurement techniques or experimental designs to address limitations identified in the current study. The chapter discusses potential extensions of the research to explore other aspects of hand-eye coordination in sports or to delve deeper into the biomechanics of the serve motion.

Practical applications: This section discusses the practical implications of the findings for coaches and tennis players. It describes how understanding the relationship between MIED and SLOP could inform the development of effective training strategies and serve techniques. The chapter likely explores how this knowledge could lead to improvements in serve performance, injury prevention, and overall player development. The chapter might offer specific recommendations for coaches and players based on the study's results.

Häufig gestellte Fragen

What is the study about?

This study explores the connection between manually influenced eye dominance (MIED) and shoulder loading position (SLOP) during a tennis serve. It specifically looks at whether a player's SLOP preference relates to their MIED, focusing on circular MIED (C-MIED) which resembles the tennis racket grip.

What are the main objectives of the study?

The main goals are to understand the link between MIED and SLOP in tennis serves, determine how often open versus closed SLOP is used, compare the results of two eye dominance tests (Porta Test and Circular Test) related to SLOP, and consider the impact of hand-eye coordination on the tennis serve technique.

What methods were used in the study?

The study involved 31 right-handed tennis players. Their SLOP was evaluated using an eight-camera VICON system, categorizing it as closed (≥90°) or open (<90°). Two eye dominance tests, Porta Test and Circular Test, were administered. Data analysis compared SLOP results with previously obtained MIED data from another study.

What were the key findings of the study?

The most common SLOP observed was closed. Comparative analysis of SLOP with the Porta Test MIED (P-MIED) and Circular Test MIED (C-MIED) revealed significant differences. A greater number of players with closed SLOP displayed crossed C-MIED compared to crossed P-MIED, indicating different associations between SLOP and the two MIED tests.

What are the strengths and limitations of the study?

Strengths likely include the use of advanced technology (VICON system) and the inclusion of both P-MIED and C-MIED analyses. Limitations might involve the sample size, the specific characteristics of the participants, and potential biases in measurements or data interpretation.

What future research is suggested?

Future research may explore the relationship between MIED and SLOP in different tennis player populations or in other sports. Alternative measurement techniques or experimental designs could address limitations identified in the current study.

What are the practical applications of this study?

Understanding the MIED and SLOP relationship could inform the development of effective training strategies and serve techniques. This knowledge could lead to improvements in serve performance, injury prevention, and overall player development in tennis.

What is "SLOP"?

SLOP stands for Shoulder Loading Position. It refers to the position of the shoulder during the loading phase of a tennis serve.

What is "MIED"?

MIED stands for Manually Influenced Eye Dominance. It refers to the dominant eye as influenced by manual tasks, such as gripping a tennis racket.

What is "C-MIED"?

C-MIED stands for Circular Manually Influenced Eye Dominance. It's a specific type of MIED assessed using a circular test and is of interest because its circular nature is similar to the grip on a tennis racket.
