In running, there is an important concept we need to know called the “gait cycle”. This starts when one foot makes contact with the ground, and ends when that same foot touches the ground again. It can be divided into two phases: the stance phase (during which the foot is in contact with the ground), and the swing phase (during which the foot is not in contact with the ground), and each phase is made up of several components.THE STANCE PHASE CAN BE DIVIDED INTO THREE STAGES:Initial contact In this stage, the heel strikes the ground and the leg decelerates for contact. The tibialis anterior muscle hold the foot in position when the contact occurs. Meanwhile the gluteus maximus muscle decelerates the leg and the quadriceps muscle extends the knee, holding the leg straight and stable. Mid-stance During the mid-stance, the body weight shifts to one foot. The knee is extended and stabilized by the quadriceps and calf muscles. At the same time the gluteus medius muscle stabili

Among fitness movements, the squat is a classic exercise that includes multiple joints and targets a variety of muscle groups. From basic to advanced, there are many different ways to do the squat, but the most popular one may be the parallel back squat. The parallel back squat needs not only muscle strength and endurance, but also requires balancing a barbell across your shoulders and upper back during the movement. There are four main muscle groups and some secondary muscles that fired in this exercise. Learning how the muscles work while squatting can help you do the exercise correctly and prevent injuries. 1. CORE MUSCLES  Core muscles include the muscles that support your back, including the erector spinae that run alongside the spine and the rectus abdominis, obliques, and transversus abdominis at the front of your body. When you perform a parallel back squats, these muscles must work hard to ensure your spine is held in the right position and that your back remain

ANKLE JOINT ANATOMYThe ankle joint consists of three joints: the talocrural joint, subtalar joint and the distal tibiofibular joint. The movements produced at this joint are dorsiflexion, plantar flexion, inversion and eversion of the foot. The ankle joint is bound by the strong deltoid ligament and three lateral ligaments: the anterior talofibular ligament, the calcaneofibular ligament and the pos terior talof ibular ligament. The functions of the ligaments are to limit extreme motion of the ankle, and to provide support and stabilize the joint.Epidemiology and Mechanism of ankle sprain There are two types of ankle sprain:     1. LATERAL ANKLE SPRAIN AND    2. MEDIAL ANKLE SPRAIN. The lateral sprain , also known as the inversion ankle sprain, is the most common type of ankle sprains. Approximately 70-85% of ankle sprain is the inversion sprain. When the ankle is inverted too much, the lateral ligament is placed on the lengthening position. In this si

During a workout session, we aim to improve muscle strength, endurance, and explosiveness. To reach these goals, hard training is supported by the four main technologies in LP compression apparel: 1. General compression - can help prevent sports injuries, reduce perceived fatigue, extend exercise time, and maintain a state of readiness. During a workout, frequent contraction and external impact causes the muscles to vibrate and oscillate. Completely covering muscles and joints with comprehensive compression can reduce the level of vibration and oscillation during exercise and reduce the pull on tendons and soft tissue while simultaneously reducing muscle swelling to help avoid injury. On the other hand, compression of muscle groups used for exercise enhances blood flow rate, accelerating oxygen efficiency and lactic acid elimination as well as rapidly remediating muscle fatigue brought about by high-intensity exercise.During a workout session, we aim to improve muscle strength, en
