What did you guys get up to yesterday? I got kidnapped. Go Olympics! #Rio2016


Lee is not a member of the New Zealand Olympic team as jiu-jitsu is not currently an Olympic sport. However, the incident is a telling one for the safety of the thousands of tourists who will be visiting Rio over the next few weeks.
According to a news source in New Zealand, Lee was forced to withdrawal NZ$850 (US$600). 
Lee recounted the incident as:
Lee was pulled over by two police on motorbikes, each armed with a pistol.
The Police said they were carrying out a routine search for drugs and weapons.
"First he asked me stretch my arms, then patted me down. He grabbed my genital area, which was quite a surprise."
"At this point it still looked reasonably professional."
After a full search of his car and person, one of officers took his license and the registration of his rented car away to his bike for a few minutes.
When he returned he was brandishing a large book, and told Lee he was breaking the law.
"He sa[id] 'you can't drive in Brazil as a foreigner without a passport,' which I now know isn't the case at all. The rental car company hadn't mentioned that to me."
"He starts opening the book, showing me all these passages in Portuguese, which I can sort of read like every third word.
The police demanded that Lee either paid them 2000 Brazilian Reais (NZ$850) or they would arrest him and take him to the federal police. 
According to Lee, when he told the men he did not have that much cash, they transferred him to an unmarked car and took him to several ATMs to withdrawal the money. He added that they later warned him not to report the incident.

Mixed Martial Arts Strength & Conditioning Coaches: Biomechanics and Anatomy Questions for review

Biomechanics Questions for Mixed Martial Arts Coaches and Strength and Conditioning Coaches like NSCA Certified Strength and Conditioning Specialists (CSCS).



Question 6
1 pts
The anterior and posterior cruciate ligaments limit which type of knee motion?





Question 8
Which of the following statements is/are true? 









  Hint:
The anterior cruciate ligament (ACL), which restricts the forward sliding of the femur on the tibial 
plateaus during knee flexion, is often injured when an athlete who is running decelerates rapidly or changes directions quickly. It is important to remember that since acceleration is a vector quantity, 
changing directions, even while maintaining a constant speed, represents a change in acceleration. The concept of angular acceleration, with direction constantly changing, is discussed in Chapter 11. The forces associated with change in acceleration based on change in direction must be compensated for by MMA and combat sports fighters.









Question 8
1 pts
Which of the following statements is/are true? 




Question 91 pts
Most human movement falls into which category? 





Question 101 pts
Abduction occurs in frontal plane 








Question 11

The three hamstring muscles are:





Question 38 
Which statement(s) is/are true?





Question 42   

The articular fibrocartilage partial disc in the knee is called ___________.







Question 44 
Where is the series elastic component (SEC) of a muscle found?
      all of the choices are correct






Question 45 

Which of the following is a behavioral property of muscle tissue?
     




Question 48 
To minimize postural adaptations, a back pack load should be as high as possible near the shoulders.


Question 52 
In human skeletal muscle, force generation capability is highest in which of the following conditions?





Question 53 
The __________________ fiber arrangement is a pattern of fibers within a muscle with short

fibers attaching to one or more tendons.





Question 55

Muscles on the anterior side of the arm produce flexion at which of the following?






Question 61 
Which of the following is not true about the menisci in the knee joint?







Question 63
Which knee ligament is most likely to be damaged from a lateral blow?














ANSWER: 
Blows to the lateral side of the knee are much more common than 
blows to the medial side, because the opposite leg commonly protects 
the medial side of the joint. When the foot is planted and a lateral 
blow of suffi cient force is sustained, the result is sprain or rupture of 
the medial collateral ligament (MCL). Modeling studies suggest that 
the muscles crossing the knee are able to resist approximately 17% of 
external medial and lateral loads on the knee, with the remaining 83% 
sustained by the ligaments and other soft tissues. However, direct 
measurements of strain to the knee ligaments indicate that external 
tibial torque is more dangerous than medially directed tibial force 
for the MCL. In contact sports such as football, the MCL is more 
frequently injured, while both medial and lateral collateral ligament 
sprains occur among wrestlers, Jiu-Jitsu fighters, mixed martial arts (MMA) fighters, and other combat sports. See combat sports statistics for the Ultimate Fighting Championship (UFC), Bellator Fighting Championship, Vale Tudo in Brasil (Brazil), and Pride Fighting Championship in Japan.


Question 63 1 pts

Which of the following causes hip adduction?








ANSWER:

Adduction
The hip adductors are those muscles that cross the joint medially and 
include the adductor longus, adductor brevis, adductor magnus, and gracilis (Figure 8-7). The hip adductors are regularly active during the swing 
phase of the gait cycle to bring the foot beneath the body’s center of gravity for placement during the support phase. The gracilis is a long, relatively weak strap muscle that also contributes to flexion of the leg at the knee. The other three adductor muscles also contribute to flexion and lateral rotation at the hip, particularly when the femur is medially rotated.





Question 72 
Internal rotation is synonymous with which of the following?










Rotation of an arm or leg as a unit in the transverse plane is called medial rotation,or internal rotation, when rotation is toward the midline of the body, and 
lateral rotation,or external rotation, when the rotation is away from the 
midline of the body.



Question 73 1 pts
Translation is a synonym for _______________ motion.










Answer:
Linear motion is also referred to as translatory motion, or translation. When a 
body experiences translation, it moves as a unit, and portions of the body 

do not move relative to each other.





Question 76
Which of the following is true regarding Osgood-Schlatter's disease?







Osgood-Schlatter disease can cause a painful lump below the kneecap in children and adolescents experiencing growth spurts during puberty.
Osgood-Schlatter disease occurs most often in children who participate in sports that involve running, jumping and swift changes of direction — such as soccer, basketball, figure skating and ballet.
While Osgood-Schlatter disease is more common in boys, the gender gap is narrowing as more girls become involved with sports.
Age ranges differ by sex because girls experience puberty earlier than do boys. Osgood-Schlatter disease typically occurs in boys ages 13 to 14 and girls ages 11 to 12. The condition usually resolves on its own, once the child's bones stop growing.
