Question

5. A gymnast reports with a possible stress fracture of the tibia. The gymnast does not recall injury to the leg. What type of mechanical loading was most likely associated with this injury? 6. A rugby player's leg is anchored to the ground and is tackled on that leg from the front while being pushed into the tackle from behind. What type of load and force are associated with this injury? muinple 7. An athlete questions the need for a warm-up to include static stretching for 30 seconds for each stretch rather than short ballistic stretches. Address the athlete's concern. Demonstrate your ability to differentiate between static and ballistic stretching using the hamstrings musculature Using the biceps brachii muscle, explain and demonstrate the difference between an isometric contraction, concentric contraction, and eccentric contraction. 8. 9. A runner wants to change his training protocol to increase his performance. What advice should be provided to the runner so as not to risk a mechanical stress-related injury? 10. A sedentary 60-year-old woman wants to begin a weight-bearing exercise program. What precautions should be taken to prevent a bone injury? Why?

Answer 1

5.At first we should care the fractured part either stress or any worsen condition ,and also there are two types or stage  of stress can occur at any type of bone in our body. Stage 1. Stress reaction 2.stress fracture. The very first stage is stress reaction which means a bone become very weak because of the loading but this type will not cause fracture or any cracks. The another stage or type can cause a transverse or oblique fracture in the tibia

6. Rugby players are more prone to getting injury to the leg. It may be an open or compound fracture. Mainly fractures are happened either direct or indirect forces here there are more chances of getting direct injury so the impact also so high when compared to the another mechanism.

7.Hamstrings is one of the long muscle in our body and it consists 4 muscles they are , 1.Long head of biceps femoris 2.Short head of biceps femoris 3.Semimembranosus 4. Semitendinosus . These muscles are helps in knee flexion and hip extension. Here the athlete may think static stretches gives more effective than ballistic stretches. The truth is both ballistic and static' stretches are more effective when its combined,lunges are best exercise to stretch the muscles in both way.

8. Biceps brachii

isometric contraction - without the movement the muscle get stretched while its maintaining in a position

Eccentric contraction - in this type muscle gets elongated during the activity example dumbbell down

concentric contraction - in this type muscle gets contracts during the activity example dumbbell raise

9. A runner should maintain their cardiovascular system. Easiest way to improve their skills and performance by doing the activity in water example is aqua therapy is the best way to improve their endurance level

10. During the weight reduction program she should care about her health conscious. She could avoid any vigorous activity to burn her calories because her bone is already may in weak due to the aging factor she might be in osteoporosis
