|
Anaerobic training |
High intensity, intermittent bout of exercise -weight training -Plyometric drills, speed, agility and interval training |
|
|
what systems are used during performance adaptations to anaerobic training |
Phosphagen (<10 sec duration, recovery in 5 to 7 mins) (alactic) Glycolytic conditioning (high intensity w shorter rest intervals) |
|
|
What happens to the size of the muscle fibers in heavy resistance training? |
the muscle fibers get larger because motor units are recruited in sequential order by their size to produce high levels of force |
|
|
To be able to get to the high threshold motor units what must the body do first |
the body must recruit lower threshold motor units |
|
|
Can anaerobic training enhance the reflex response, thereby enhancing the magnitude and rate of force development |
Yes it can through plyometrics |
|
|
Muscle hypertrophy |
refers to the muscular enlargement from an increase in the cross sectional area of the existing fiber |
|
|
Hyperplasia |
an increase in the number of msucle fibers via longitudinal fiber splitting |
|
|
What happens during the process of hypertrophy |
an increase in the synthesis of the contractile proteins actin and myosin within the myofibrils |
|
|
In resistance training how are the muscle fibers effected? |
It results in an increase in both type 1 and type 2 muscle fibers -Type 2 fibers have a greater increase in size than type 1 fibers |
|
|
what are some structural and architectural changes that happen with resistance training? |
–Resistancetraining increases myofibrillarvolume, cytoplasmic density, sarcoplasmic reticulum and T-tubule density, and sodium–potassium ATPase activity.
-Sprint training enhances calcium release -reduced mitochondrial density -decreased capillary density |
|
|
Within muscle strength and hypertrophy what will happen to bone mineral density with anaerobic training |
increase the force exerted on the bones with will increase bone mineral density |
|
|
what are the components of mechanical lad that stimulates bone growth? |
magnitude of load (intensity) rate (speed) of loading Direction of the forces volume of loading (number of repetitions) |
|
|
How can athletes stimulate bone formation with in connective tissue adaptations? |
Use exercises that directly load particular regions of the skeleton Use structural exercises to direct force vectors through the spine and hip and allow the use of greater absolute loads in training |
|
|
which of the following are primary neural adaptations to anaerobic training? |
increased neural drive and reductions in inhibitory mechanism |
|
|
_______ is the enlargement of muscle fiber cross sectional area and ______ is the increase in the number of muscle fibers via longitudinal fiber splitting. |
Hypertrophy; hyperplasia |
|
|
which of the following have been observed in men in elevated concentrations up to 30 mins after a resistance training workout? |
Testosterone, growth hormone, and cortisol |
|
|
as an adaptation to anaerobic training, which of the following is the benefit of the stretch reflex harnessing the involuntary elastic properties of muscle? |
Increased force production |
|
|
As an adaptation to resistance training, which of the following is a beneficial change in pinnated muscles? |
Increased fascicle length |
|
|
Minimal essential strain is the minimal threshold stimulus needed to cause which of the following changes? |
Bone formation |
|
|
Which of the following is an adaptation in tendons from high intensity anaerobic training? |
Increased packing density of collagen fibrils |
|
|
All of the following factors affect the degree to which blood flow is increased in the working muscles during anaerobic training EXCEPT: |
Resting heart rate of the athletes |
|
|
An athlete has spent the last four resistance training sessions overworking his body. he is hoping to see a substantial increase in performance after a week of active rest. which of the following describes his current conditions? |
Functional overreaching |
|
|
which of the following is a symptom specific to nonfunctional overreaching? |
Decreased muscle glycogen |
