The aim of this study is to identify the effects of the correction exercise program on gait and landing ground reaction force characteristics in individuals with genu valgus. An experimental study with a randomized controlled trial design will be used. Twenty six subjects with genu valgus will be classified in two groups: the experimental group (n=13) and the control group (n=13). The experimental group will conduct correction exercise program for 35-40 minutes at each session, 3 times a week, for 16 weeks, while the control group did not perform any exercise. Two Kistler force plates (Kistler AG, Winterthur, Switzerland) will be used to record the GRF components during bilateral drop landing abd gait with sampling rate of 1000Hz.

Intervention groups
1
Description
Intervention group: Elastic tubing (Thera-Band, Akron, Ohio, US) ranging from very low to very high resistance (yellow, red, green, blue, black and silver) will be used. The Intervention group will be performed stretch training protocol (first two weeks) for the hip adductor, biceps femoris and tensor fascia latae muscles consisted of static stretching performed in four sets of 30s for each movement. After stretch training protocols, the experimental group wil be performed resistance thera-band exercises at three times per week for fourteen weeks (i.e., 42 strength training sessions). The participants will be familiarized with the training techniques prior to training. Each exercise session will be consisted of a general warm-up of 10 minutes, followed by a resistance training session (35- 40 minutes) and was completed by a cool-down routine. Exercises were preceded by warm-up sets, while all thera-band training was closely will be supervised and the participants will be received consistent verbal instructions. Following an adaptation phase of four weeks using low external resistance (yellow Thera-Band®, 1 set of 14 repetitions per exercise with a higher resistance only if the subject was obviously unchallenged) exercise intensity was progressively increased by adapting the resistance of the elastic band (based on the Thera-Band® force-elongation table) from yellow to red and further to black. In addition, the exercise volume will be extended by increasing the number of sets from one to two. Rate of progression will be based on individual improvements (band colour will be changed if participant would have been able to perform two more repetitions in the second set) .
