Horse riding influence for legs muscles activities

Abstract

Introduction: Genu valgum, or “knock-knees”, is a deformity in which there is decreased space between the kness. If the described angle is less than 170 degrees, it is considered genu valgum. Genu valgum may place excessive tensile stresses or strain on the structures on the medial side of the knee and compressive forces on the lateral compartment of the knee. Muscles may become unbalanced as a result of adaptation or dysfunction. Such muscle imbalances can be either functional or pathological. Strength ratios are used to quantify muscle imbalance between agonists and antagonists in the study of sport injuries. When the muscles are imbalanced, human gait cycle get disrupted. There are two phases of gait cycle: stance phase and swing phase. Stance phase takes 60% of gait cycle and 40% of swing phase. Aim: Identify horse riding influence for legs muscles activities. Goals: 1. Identifyfactors, who can caused genu valgum deformity. 2. Evaluate genu valgum deformity and muscle balance. Methods: Comprehensive searches of the LSMU library, MEDLINE (via PubMed) will be completed using the following keywords: horse riding, knee genu valgum deformity and related entry terms. The reference lists of included studies will be hand searched. Relevant data will be extracted from included studies using a specially designed data extraction sheet. Conclusions: 1. Genu valgum deformity depends: type of saddle, workout time, workout amount per week, number of horses equestrians ride per day. 2. Genu valgum “knock-kness” deformity caused muscles imbalance. Legs adductor and hamstring muscles are tighten and legs abductor are stretched.
