Kines 165 Exam 1, Kines 165 Questions with
Answers (100% Correct Answers)
what are the components of fitness? Answer: cardiorespiratory endurance,
muscular strength, muscular endurance, flexibility
cardiorespiratory endurance Answer: ability of heart, lungs and blood vessels to
deliver adequate amounts of 02 to working cells to meet the demand of
prolonged exercise
ability to sustain low intensity exercise for long periods of time (ultra
marathons)
how are prolonged, sustained activities accomplished? Answer: by a constant
blood flow to the working muscles and O2 extraction
what is cardiorespiratory endurance dependent on Answer: -The pulmonary
system to deliver O2 in the CV system to muscles
- muscles ability to extract and consume O2 via Aerobic
- substrate availability (especially in high intensity)
prolonged, sustained activity Answer: relies on aerobic energy systems for the
sake of on-going need of ATP regeneration
adequate and sustained supply of O2 to the working muscles' mitochondria is
needed for ATP regeneration
Aerobic Power(VO2max) Answer: -best index for CR fitness
- great reliance on O2 delivery, extraction
,2
Fick equation Answer: HRmax (b/m) x SVmax (ml/b) } markers of O2
delivery
a-VO2Dmax (ml/dL) ---> marker of O2 extraction
What is an important factor that the VO2max score determines? Answer:
Athlete's ability to sustain high-intensity exercise
Why does Vo2max determine the ability to sustain high intensity Answer: -
more muscle is recruited (including heightened recruitment of FT fibers) for the
sake of sustaining the fast leg turnover thus increase in demand for ATP
Is VO2max more important for a miler or a marathoner? Answer: Miler - they
go faster
ATP synthesis rate is a function of what? Answer: O2 consumption
The direct assessment of O2 power requires what? Answer: incremental
exercise test taken to volitional exhaustion and collection of expired gases
what is the relationship between ATP synthesis and VO2 synthesis Answer:
directly proportional
more important for 1,500m, 5K, 10K, marathon? Answer: 1,500m Because it
uses the highest amount of energy because it needs the biggest amount of force
attainment of a high VO2maz has an important physiological meaning Answer:
A high aerobic power requires the integrated and high-level response of diverse
physiologic support systems.
VO2max score provides a ________ expression of maximal capacity for aerobic
ATP regeneration. Answer: quantitative
What is the most important component of health-related physical fitness?
Answer: Aerobic Fitness
what is the best indicator of overall health Answer: Aerobic Fitness
, 3
what is the relationship with disease and mortality and CR fitness Answer:
Inverse
Epimysium Answer: surrounds entire muscle
Perimysium Answer: Connective tissue surrounding a fascicle
Fasculus Answer: bundle of muscle fibers
Endomysium Answer: Connective tissue surrounding a muscle fiber
Muscular strength Answer: the ability of a muscle (or muscle group) to express
maximal force against nature
what is muscular strength influenced by Answer: - Muscle size, Fiber type,
resistive trained state (size and Neuromuscular skill (NM), NM skill,
Biomechanics,
-Order
what explains fast initial increase in strength Answer: the increase in
neuromuscular recruitment
what promotes skeletal hypertrophy Answer: resistive training
what happens to the force produced by a muscle when the number of units are
recruited Answer: the amount of force increases
during a typical 8-wk training period the neural factor accounts for
approximately Answer: 90% of the strength gained
Work equation Answer: W=Fd
How is muscle strength tested? Answer: 1RM technique
Muscular power Answer: the rate of doing work (power=work/time)
