(29 cards)
VO2 max is depended on
Training Nutrition Genetics Heart pumping capacity Heart volume
VO2 max of 18-35 yo
At least 70 ml/kg/min
High as 90
What is genome
The genome is the genetic fingerprint of an individual organism
How many genes in human genome
~35000
Characteristic of a differentiated tissues
Only some cells produce some specific proteins
Coding sequence is called
Exons
Non coding sequence is called
Introns
Purines
Guanine
Adenine
Pyrimidine
Cytosine
Thymine
New DNA strands are
Complementary
After transcription mRNA goes to
Cytoplasm from nucleous
Ribosomes are located in the
Cytoplasm
Function of tRNA
Carry AA to ribosomes
Different types of cells/tissues are determined by
Partial expression of the DNA
Resisitance training increase
Of most proteins in skeletal muscle
Similar to increase in muscle specific proteins during embryonic development
Endurance training increase in
Mitochondrial density without change in muscle size
Inherited defects occur from
Ganete ( sperm/egg) mutations
Mutation rate
~ 1 in 25,000 gametes
Name some sex linked genes
Hemophelia
Color blindness
Duchenne muscular dystrophy
T/F
In monozygotic twins muscle fibers type composition is almost identical
T
T/F
In non athletes , # of type 1 fibers ~= # of type II fibers
T
T/F
Great variation between elite sprinters and elite marathoners in ratios of type 1 to type II fibers
T
In non athletes most type II fibers are
II-X
In athletes ——fibers are more prevalent
II-a
