The aim of this study was to determine the differences in golf swing execution in terms of the parameters of the pelvis and thorax movement between the sexes in junior golfers and their relation to the golf club velocity. Elite female and male players (age: 15.4 ± 1.0 and 15.8 ± 1.7 years, respectively) performed 10 golf swings with a driver under laboratory conditions. Pelvis and thorax movement parameters and golf club velocities were measured using a three-dimensional motion capture system. Statistical parametric mapping analysis of pelvis-thorax coupling revealed a significant difference ( < 0.05) between boys and girls during backswing. Analysis of variance showed a significant effect of sex on the parameters of maximal pelvic rotation (F = 6.28, = 0.02), X-factor (F = 5.41, = 0.03), and golf club velocity (F = 31.98, < 0.01). No significant relationship was found between pelvis and thorax movement parameters and golf club velocity in the girls. We found a significant negative relationship between the parameters of maximal thorax rotation and golf club velocity (r = -0.941, < 0.01) and between X-Factor and golf club velocity (r = -0.847, < 0.05) in the boys. We suggest that these negative relationships in males were caused by the influence of hormones during their maturation and biological development, where there is decreased flexibility (lower shoulders rotation and X-factor) and growth of muscle strength (higher club head velocity).

Significance: Evaporative dry eye disease, due to meibomian gland dysfunction, causes significant suffering for millions of people globally, yet satisfactory long-term treatment remains elusive for many. Investigation of potential therapies for meibomian gland dysfunction is therefore of high importance to clinicians and their patients.
Purpose: This study aimed to compare the efficacy of a new device for meibomian gland debridement and expression to that of the conventional way of providing this treatment.

Background: Understanding participation in sport is important for sport policy, strategy and management. Most research regarding participation in sport report general trends in participation rates. However, as societies trends in leisure-time activities are changing, we need to also understand the settings of sport participation.

This study introduces an innovative integration of Laban Movement Analysis (LMA) with biomechanical principles to examine the golf swing dynamics from an ecological perspective. Traditionally, LMA focuses on the qualitative aspects of movement, often isolated from external influences. This research bridges that gap by investigating how golfers manage and adapt to the inertial forces of the club throughout the swing.

Background: Golf club-related traumatic brain injuries are an uncommon occurrence in adults, and the use of golf clubs as a weapon of interpersonal assault resulting in compound skull fractures is rare.
Objective: To present a case series of golf club-related compound skull fractures in adults secondary to assault, representing the largest study of this entity to date.
Methods: A retrospective analysis was performed of a prospectively maintained database for patients admitted to Tygerberg Academic Hospital in Cape Town, South Africa, with golf club-related compound skull fractures between 1 January 2018 and 31 December 2021.
