Aktiviti 2 : Analisis DataMethod 1 Calculation Total perimeter for first lane = 400 mDistance from the finishing line = 400 400 = 0 m

Total perimeter for second lane = 200+2(103.771)= 407.543Distance from the finishing line = 407.543 400 = 7.543 m

Total Perimeter for third lane = 200+2(107.543)= 415.086Distance from the finishing line = 415.086 400 = 15.086 m

1. Runner's knee.This is a common overuse injury. Runner's knee has several different causes. It often happens when your kneecap is out of alignment.Over time, the cartilage on your kneecap can wear down. When that happens, you may feelpainaround the kneecap, particularly when: Going up or down stairs Squatting Sitting with the knee bent for a long time2. Stress fracture.This is a small crack in a bone that causes pain and discomfort. It typically affects runners in the shin and feet. It's often due to working too hard before your body gets used to a new activity.Pain gets worse with activity and improves with rest. Rest is important, as continued stress on the bone can lead to more serious injury.3. Shin splint.This is pain that happens in the front or inside of the lower leg along the shin bone (tibia).Shin splintsare common after changing your workout, such as running longer distances or increasing the number of days you run, too quickly.People with flat feet are more likely to develop shin splints.Treatment includes: Rest Stretching exercises Slow return to activity after several weeks of healing4. Achilles tendinitis.This is inflammation of theAchilles tendon. That's the large tendon that attaches the calf to the back of the heel.Achilles tendinitis causes pain and stiffness in the area of the tendon, especially in the morning and with activity. It is usually caused by repetitive stress to the tendon. Adding too much distance to your running routine can cause it. Tight calf muscles can also contribute.Treatment includes: Rest Icing the area Calf stretches5. Muscle pull.This is a small tear in your muscle, also called a muscle strain. It's often caused by overstretching a muscle. If you pull a muscle, you may feel a popping sensation when the muscle tears.Treatment includes RICE: rest, ice, compression, and elevation.Muscle pull commonly affects these muscles: Hamstrings Quadriceps Calf Groin6. Ankle sprain.This is the accidental stretching or tearing of ligaments surrounding the ankle. It often happens when the foot twists or rolls inward.Sprains typically get better with rest, ice, compression, and elevating the foot.7. Plantar fasciitis.An inflammation of the plantar fascia. That's the thick band of tissue in the bottom of the foot that extends from the heel to the toes.People with tight calf muscles and a high arch are more prone to plantar fasciitis. Although it may be linked to adding activity, plantar fasciitis can also happen without any obvious reason.
