W.I.T.S test 3 2023-solved

What is the primary energy source for all biological work? - Answer- ATP The primary source for ATP for 50 m dash is? - Answer- Creatine phosphate Which of the following skeletal muscle fiber types is fast,generates high force, and is resistance to fatigue? - Answer- Type 2a People with CVD can obtain large improvements in VO2max through endurance training? True/false - Answer- True Blood glucose is the primary carbohydrate fuel for heavy exercise less than 2 hours? True/false - Answer- True When clients exercise at 65% for 90 minutes,what is the typical response of the R(respiratory exchange ratio)value ,and what does this response mean? - Answer- It typically drifts downward,indicating a greater reliance on fat for fuel Which of the following skeletal muscle fiber type demonstrates the highest rate of contractile force when stimulated to contract? - Answer- Type 2x With regards to the initiation of muscle contraction,which of the following is the primary link between the action potential and movement of the cross bridges? - Answer- Calcium At an R value of 0.75, the primary fuel being metabolized is? - Answer- Fat Which of the following fiber muscle types would demonstrates a slow rate of contraction low force production and high fatigue resistance - Answer- Type 1 Vo2max (maximal oxygen consumption ) is the greatest rate at which oxygen can be delivered to the working muscle during dynamic exercise? True/false - Answer- True Systolic blood pressure increases with each stage of a gxt whereas diastolic blood pressure remains the same or decrease? True/false - Answer- True During the coarse of a graded maximal exercise test GXT taken to volitional fatigue, you should expect to see the R value? - Answer- Increase During from transition from rest to steady state exercises, ATP demands must be met initially by ATP-PC system and anaerobic glycolysis since oxygen delivery to the cells cannot instantaneously increase. This lag in oxygen delivery is called? - Answer- Oxygen deficit Following a 15 week endurance training program, which of the following responses would you expect to see( compared with pre training ) regarding the heart rate(HR)? - Answer- Lower HR at sub maximal workloads Following a 15 wk endurance training program, which of the following responses would you expect to see (compared with pre training ) regarding cardiac output? - Answer- Higher cardiac output at maximal workloads and unchanged cardiac output at sub maximal workloads Following a 15 week endurance training program, which of the following responses would you expect to see ( compared with pre training ) regarding stroke volume? - Answer- Higher S.V at sub maximal workloads During a GXT, which of the following is responsible for increasing cardiac output once maximal SV had been reached? - Answer- Increased HR During times of reduced training volume, which of the following is the most important training variable linked to the maintenance of CRF? - Answer- Exercise intensity Among the overall population of the average male and. Female, muscle fiber distribution is predominantly made up of? - Answer- Type 1 muscle fibers Which of the following is not one of the four bone classification? - Answer- Regular An example of a sesamoid bone is the? - Answer- Patella An example of a long bone is the ? - Answer- Ulna An example of a short bone is the? - Answer- Carpal The periosteum is? - Answer- The fibrous membrane covering a bone except where articulating cartilage is present Synarthrodial joints ? - Answer- Allow no movement Which of the following statement is true? - Answer- Articulating cartilage covers the articulating surface of diarthrodial joints The primary factor that determines the ROM at a joint is? - Answer- The shape of the bones and their articulating ends Flexion and extension occurs In the transverse plane? True/false - Answer- False Abduction and addiction of the leg are movements in the frontal plane? True/false - Answer- True Internal and external rotation are movement
