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?

knee hyperextension

forward and backward sliding of the femur on the tibia during knee flexion and extension

lateral knee motion

both knee hyperextension and the forward and backward sliding of the femur on the tibia during knee flexion and extension

all of the choices are correct

Question 8

Which of the following statements is/are true? 

when the knee undergoes a significant amount of flexion, it is necessary for the femur to slide forward on the tibia in order to prevent its rolling off of the tibial plateau

during extension, the femur must slide backwards on the tibia

both that when the knee undergoes a significant amount of flexion, it is necessary for the femur to slide forward on the tibia in order to prevent its rolling off of the tibial plateau and that during extension, the femur must slide backwards on the tibia

none of the statements 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.

True

False

Question 11

Question 38

exercise can increase the size and strength of tendons

exercise can increase the size and strength of ligaments

exercise can increase the strength of tendon junction with a bone

exercise can increase the size and strength of both tendons and ligaments

all of the choices 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?

tendons

ligaments

]muscle membrane

      all of the choices are correct

Question 45 

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

ability to develop tension

extensibility

irritability

all of the choices are correct

Question 48 

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

True

False

Question 52 

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

muscle is at resting length

muscle is slightly shortened

muscle is slightly lengthened

muscle length is irrelevant to force production

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?

the shoulder

the elbow

the wrist

all of the choices are correct

Question 61 

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

made of cartilage

larger surface area to distribute load

does not absorb shock

all of the choices are true

Question 63

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

medial collateral

lateral collateral

anterior cruciate

posterior cruciate

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?

adductor magnus

adductor longus

gracilis

both adductor magnus and longus

all of the choices cause 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?

medial rotation

lateral rotation

external rotation

none of the choices are correct

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

BJ Penn vs Frankie Edgar training videos. How should Penn change his training for his fight against Matt Hughes at UFC 123?

Matt Hughes Vs Bj Penn III at UFC 123 in the Motor City Detroit, Michigan!

Both fighters have officially confirmed that they will be fighting for the third time at UFC 123. This third bout will be the tie breaker for the two former champions. They first met at UFC 46 in January 2004, where Penn earned the "W..." via rear naked choke and was crowned the new champ. They met once more at UFC 63 where Hughes got his revenge and finished Bj via TKO in the third round.


UFC 123 will be the promotion's first trip to Michigan since UFC 9 in Detroit in 1996. Though not officially announced by the UFC, the main event is expected to be a light heavyweight bout between former champions Lyoto Machida and Quinton "Rampage" Jackson.

 

We have enjoyed reading Penn's "Mixed Martial Arts: Book of Knowledge" and respect his abilities. We will make a special trip to show Penn these equipment if he asks us because we want to see him win again.

 We highly recommend the plyometrics training materials by Todd Durkin and Training For Warriors.

Watch Penn's training videos (below) four weeks before his fight with Frankie Edgar and let us know how you think he should train more effectively for his fight with Matt Hughes.  We strongly advocate new advanced training drills with an enforcer trainer who will increase the intensity of his training by using advanced drills with kettle bells, medicine balls, and the items below for improved stamina and better leg strikes.

We also have a contact who sells Cap kettlebells in Southern California at great prices. We just bought a bunch and love using them for our outdoor boot camp workouts in West L.A. with MMA drills.  You can swing and shot put them like the ancient Greco-Romans in the sand for added resistance and for advanced drills on a BoSU (Both Sides Up) platform. Please check with your medical doctor and health professionals before beginning any exercise program.

Basic Tips When Buying Running Shoes
New Balance Trail Running Shoes have additional support for plyometrics and weight lifting. New Balance also offers shoes based on different width sizes. Step on a piece of blank paper with moderate pressure when each foot is wet to make an imprint.  The more of your foot you see the more flat footed you are.  Tell this to the salesperson at a reputable store and ask them to test your foot for supination (foot tends to shift outwards) or pronation (foot tends to shift inwards) so you can buy shoes that are best for you.

Add Instability to Your Workout to increase Intensity
