Secondly, "the accurate alignment of the body at the end of the board must be maintained through the flexion of the knees and push-off with the accompanying extension of the ankles". Proper poise is required at the initiation of the approach of a dive. According to studies by Pruett 1981and reported by the university of Texas, Grace and balance are largely the result of proper body alignment and kinesthetic awareness. In closed skill sports such as swimming, pole vaulting or sprint kayak, performance depends upon an ability to accurately reproduce a movement with minimal variation. This technical mastery requires a physical structure that supports the sport's biomechanics, the neuromuscular coordination to correctly sequence the movement, the psychological skills to focus effort without unnecessary tension and the physiology to sustain the movement pattern until the event is completed. In every sport there are athletes who represent true technical excellence. To perform diving techniques, high power is required for hip, knee and ankle joint muscle groups. There are also special challenges regarding diving and diver approach on springboard. Injuries sustained during diving can either result from catastrophic overloading of joints during a poorly executed dive or, more commonly, from repetitive loading at lower levels of force, such as during a successful dive. Such effects may develop individual risk factors for postural changes, which in turn may cause injury. These repetitions may lead to imbalances in the musculoskeletal system due to changes in strength, flexibility, balance and coordination of movement, as well as a direct impact on the pattern of bone growth. dynamic ankle malalignment in both “HF” and “HPF” steps had a significant inverse relationship with Coach Score.Ĭonclusions: There was a significant inverse relationship between FDS score and “Ankle Eversion/ Eversion, Knee and Hip Abduction/ Adduction” in Swing or Stance Leg.Įxercise training is based on continual repetition of main movements. There was a significant inverse relationship between FDS score and “R. Results: There was a significant inverse relationship between FDS score and “L. The relationship between the performance score of "FDS" and dynamic malalignment of Ankle, Knee and Hip joints in the frontal plane at each step was determined using “Generalized Estimating Equation” (GEE) with the “Identity Function” and the “Normal Distribution”.

The x and y coordinates of each marker were estimated using the KINOVEA software.

The subjects performed FDS technique in one of two ways either the "Hurdle Pre-Flight" or "Hurdle Flight”, and head coach gave them scores. Methods: The subjects of this study were the 12 top divers of Iranian League Championship. Objectives: The present study is a correlational study that was conducted to obtain complete and accurate information by examining “the relationship between diving score and dynamic malalignment of Hip, Knee and Ankle on a 1 m springboard by elite male divers.”
