Effects of FIFA 11+ With Dynamic Core Stability Training on Balance and Dynamic Knee Valgus in Amateur Soccer Players

Effects of FIFA 11+ With and Without Dynamic Core Stability Training on Balance and Dynamic Knee Valgus in Amateur Soccer Players at Risk of Anterior Cruciate Ligament Injury

The incidence of soccer-related injuries is reported to have the highest rate amongst all sports. To reduce the incidence of soccer injuries in youth and amateur soccer players, an injury prevention framework namely FIFA 11+ was established. Although the FIFA 11+ is a comprehensive warm-up and training program for soccer players, yet in the second component focusing on strength and plyometric training, the exercises consist of only static core training whereas dynamic core training is not included in the protocol. Hence this study will observe the effect of including dynamic core training targeting the remaining core musculature as well in the FIFA 11 + program for risk factor modification and correction of muscular imbalance.

Soccer (football) is one of the most popular sports in the world. Intense soccer actions (i.e., acceleration, decelerations, change of direction, sprinting, tackling, running, being tackled, and shooting, twisting, turning, jumping and landing during the game) in addition to high impact and forceful body contacts during practice sessions and matches predispose the athletes to injuries. various contributing factors of these injuries include muscular imbalance, joint instability, lack of proper training and inadequate rehabilitation. Poor landing mechanics, specifically, increased dynamic knee valgus, is also associated with increased risk for lower limb injury, particularly ACL injury. The modifiable factors are shown to be responsive to different types of trainings. In fact neuromuscular factors are involved in control of dynamic knee stability, hamstrings and quadriceps imbalances, asymmetry of legs and core dysfunction. The latest FIFA 11+ developed in 2006 was designed to be used as pre-training protocol to improve the components of physical fitness that might contribute to injury prevention. In this program, there is a combination of three major exercise regime components: an initial running and stretching exercises, second component of strength, plyometric and balance exercises, ending with high speed planting and cutting exercises. One of the component of this program involves the training of core musculature. While the core muscles (including muscles of trunk and pelvis) do not cross the knee joint, yet core stability can modulate the lower limb alignment and loading during dynamic tasks. Hence, this study will be conducted to find whether there is any effect of including dynamic core training in the FIFA 11+ program in order to correct muscular imbalances and ultimately risk factor modification. A two-arm single blinded randomized controlled trial will be conducted to find out the dynamic knee valgus alignment, postural stability and single leg athletic stability and lower limb muscles strength, while the secondary outcomes would include lung function tests (FEV1, FVC & FEV1/FVC ratio). In the control group, standard FIFA 11+Protocol will be followed consisting of slow paced running exercises followed by strength, plyometric and balance training. In the experimental group, FIFA 11+ protocol along with additional dynamic core exercises will be followed including leg raises, crunches, superman, plank hip twist, and supine bridge.All exercises in both groups will be progressively increased as per established protocol. Training will be provided 3-4 Times a week for 8 Weeks on alternate days.
