Competition climbing has grown increasingly in popularity, and many people are being drawn to this sport with a parallel increase in the occurrence of sport-related injuries. One of the most common and unique lesions occurring in the rock climbing population is the closed rupture of the flexor pulley system of the fingers. This lesion is strictly related to some climbing techniques in which the entire body weight is placed on fingerholds, which causes bowstringing of the flexor tendons with subsequent loss of strength across the full range of motion of the finger. This article summarizes the current literature regarding the application of imaging modalities in the diagnosis of rock climbing injuries with a specific focus on ultrasound and magnetic resonance imaging. Biomechanics of the sporting activity and resultant pathophysiologic and clinical considerations concerning flexor pulley system injuries are also discussed.

We honor Professor Hartmut Karl Lichtenthaler, a versatile pioneer of photosynthesis research, plant physiology, isoprenoid biochemistry, and stress physiology of plants, for his groundbreaking and creative contributions to plant science. His innovative research on the chemical composition, ultrastructure, and function of chloroplasts and his detection of the major methylerythritol 4-phosphate (MEP) isoprenoid biosynthetic pathway in plants is key to our current understanding of the physiology and biochemistry of photosynthesis systems. His ingenious use of the powerful laser-induced chlorophyll fluorescence imaging has helped us better understand the stress response processes in plant leaves.

Background: Medical training therapy (MTT) is an advanced, individualized rehabilitation approach that integrates multiple methods to improve physical function. It is widely applied to rehabilitate sports injuries. This randomized study evaluated MTT's effects on physical injury rehabilitation, mental function, and athletic performance in elite rock climbers.

: Sport climbing's popularity has grown with its inclusion in the Olympics and increased accessibility. Understanding the relationship between hand dominance, grip strength, endurance, and the involvement of masticatory and neck muscles can provide valuable insights into the neuromuscular adaptations specific to sport climbing, potentially aiding performance optimization and injury prevention in intermediate and advanced climbers. This study analyzes if the dominant hand has greater isometric endurance and isometric manual grip strength parameters than the non-dominant one and examines its relation to the masticatory and neck muscles in intermediate and advanced sport climbers.

Recent reviews have highlighted conflicting findings regarding the validity of finger flexor strength and endurance tests in sport climbers, often due to small sample sizes and low ecological validity of the tests used. To address these gaps, 185 male and 122 female climbers underwent maximal finger flexor strength, intermittent and continuous finger flexor endurance, and the finger hang tests in a sport-specific setting to determine the predictive and concurrent validity of these tests. The finger hang test showed the strongest relationship to climbing ability for both sexes ( ≈ 0.

Rock climbing requires specific hand positions with high force outputs to adapt to changing terrain requirements. The purpose of this study was to explore associations between years of climbing experience, the frequency of training, and skill level on force production in 2 different climbing-specific hand positions.
