The COL5A1 Gene Allelic Combination and ACL Injury Risk in Team Sport: A Preliminary Report.

 The aim of this study was to examine the relationship between BstUI restriction fragment length polymorphisms (RFLP) C/T (rs 12722) and DpnII RFLP B1/B2 (rs 13946) COL5A1 polymorphisms and the anterior cruciate ligament (ACL) rupture in competitive team-sport athletes.  Sixty-eight team-sport players (n = 36 women and n = 32 men) with non-contact ACL rupture (ACLR) occurred during sport practices (ACLR Group) and 42 healthy players (n = 20 women and n = 22 men) (Control Group) participated in the study. Genomic DNA was extracted from buccal swab with salting out method.

Collagen Gene Variants and Anterior Cruciate Ligament Rupture in Italian Athletes: A Preliminary Report.

Several studies have investigated the role of genetics in anterior cruciate ligament (ACL) rupture, often returning conflicting results. The present pilot study aimed to analyze the association between six Single Nucleotide Polymorphisms (SNPs) (rs1800012; rs12722; rs13946; rs240736; rs970547; and rs4870723, located on the , , , and genes), and ACL rupture, among Italian athletes. A hypothesis-driven association study was conducted.

SILENT DELTOID ATROPHY IN BEACH VOLLEYBALL PLAYERS: A REPORT OF TWO CASES AND LITERATURE REVIEW.

Unlabelled: While examining the shoulders of 91 professional and semi-professional beach volleyball players, the authors observed two cases of grave atrophy of the deltoid muscle following painless axillary neuropathy, not resulting from any trauma. The causes, the clinical history and the untreated history of the entrapment of the axillary nerve in the quadrilateral space in sportsmen, are discussed on the basis of the presentation of the two cases illustrated and from existing literature.

EMG amplitude of the biceps femoris during jumping compared to landing movements.

Hamstrings injury is a common occurrence in athletic performance. These injuries tend to occur during a deceleration or landing task suggesting the negative work may be a key component in hamstrings injury. The purpose of this study was to investigate the muscular activity (EMG) of the biceps femoris (BF) in different phases (concentric vs.
