Barometric Pressure will

Answer 11

decrease when getting to a higher altitude

Question 12

Decrease within indiviudals VO2 and VO2max as we go higher in altitude

Drops 8-11% per 1,000 m ascent

Question 13

Thinner air (at higher altitudes) =

Answer 13

less air resistance

making throwing a ball faster

Question 14

Hematocrit changes

Answer 14

percentage of red blood cells compared to blood sample

women tend to have lower while men will have higher

Question 15

When you go to higher altitude places your hemacrit will

Answer 15

will go up when there is a decrease in plasma volume when exposed to altitude

Question 16

Q angle

Answer 16

women have an increased Q angle than men because they have a wider pelvis

Higher risk for athletes when there is jumping and landing with an increased Q angle

Question 17

Weight bearing exercises/Resistance Training

Answer 17

maintains bone mineral density regardless of sex

tend to see women lose bone marrow density

but resistance training will slow that down

Question 18

Women are at higher risk for

Answer 18

Osteopenia/osteoperosis

Question 19

Trasngender U.S. hormone therapy

Answer 19

gender hormone therapy can change your performance

Seen over 2+ years

Question 20

Mentstral Cycle causes

Answer 20

A change within womens hormones

Question 21

Why are women under represented in research?

Answer 21

men have more stable hormones than women

Women have fluctuating hormones

Question 22

Follicular Based Training

Answer 22

Is there merit within the research

More volume and intensity has been shown to be appropraite during the follicular phase of menstraul cycle

Researchers found better lean body mass gains in the increase of workouts during that follicular phase

Question 23

Performance in women during menstral cycle

Answer 23

havent seen any changes in performance

Question 24

Pregnancy also an expert talk on it

Answer 24

very under represented

avoid increasing intensity darastically and if you are increasing it increase it slowly

listen to body

stay active if can

Improvement risk of falling

benefits outweigh risk when exercise is properly conducted

Question 25

Why are children’s economy of effort worse than adults?

Answer 25

children are spases, cant move body as well, a childs stride is shorter adults have a longer stride length

Question 26

Physiological Differences between size of individuals Stroke volume Heart rate Lung function

Answer 26

Stroke Volume will be lower in children Lung Function - total capacity will be smaller in children (think about size of organs) Heart rate in kids is faster because heart is smaller

Question 27

Weightlifting

Answer 27

Safe yes Benefits yes children improve strength on nueral adaptations improvement side, but do not put on a bunch of weight Teens and Adults - motor unit recruit will increase in first few session or year (beginner gains)

Question 28

Healthy Aging Bone Mineral Content …….

Answer 28

Bone Resorption greater than bone synthesis due to lack of weight bearing exercises Decrease in size of # muscles fibers and decrease in content of muscle fibers less physcically active as older which will make them lose body mass and body size

Question 29

Size and number of muscle fibers ……… with age As we age we will be losing

Answer 29

Decrease As we age we lose skeletal muscle size and fiber

Question 30

Resistance training reduces

Answer 30

muscle atrophy and increases muscle cross sectional area

Question 31

(Aging) bone marrow density will

Answer 31

Bone resorption rates will be exceeding the bone sythesis rate bone marrow density will decrease with age resistance training is good to slow this down

Question 32

Heart Maximal stroke volume will ……

Answer 32

decrease with age and decrease in contractility ( stretchiness of heart muscle)( house more blood when you have a lot of stretchiness)

Question 33

Maximal Heart rate as we age

Answer 33

max heart rate will go down as we age 220- age = Max Heart Rate

Question 34

VO2 Max

Answer 34

Vo2 max is at its peak while your age 20-30 still remain active In active adults 5- 6 % decline per decade 3.6% decline over 25 years in elite athletes 15% decline per decade in previously active adults
