Q

Four major changes of puberty

A
  1. Development of primary sex characteristics (testes and ovaries)
  2. Development of secondary sex characteristics (physical appearance)
  3. Rapid physical growth spurt in height and weight
  4. Changes in body proportions

More susceptible to injury during this time!! implications for PT

Q

How does puberty relate to female athletes?

A

-playing sports can delay menarche or cause menstrual irregularities (either prevent or irregular cycle)
-female athletes with low body weight in particular are affected

Q

Changes in body proportions during puberty

Study These Flashcards
A

Face: nose reaches adult size first
Hands + feet: reach adult size before arms and legs
Limbs + trunk: LE becomes longer than trunk

Bones grow faster than muscle, so leads to poor length-tension relationship and awkward movements

24
Q

When does bone growth stop in adolescents?

Study These Flashcards
A

18 for girls and 21 for boys

25
Skeletal maturity is attained when _______
the epiphyseal plates close
26
When do epiphyseal plates close?
cranial bones: 2 years old vertebral arches: 1 year old, lumbar spine 6 years old ALL GROWTH PLATES CLOSED AT 25 YEARS OLD
27
What should you not do over a growth/epiphyseal plate?
Ultrasound It can lead to asymmetrical growth of that joint
28
When do growth plates of long bones close?
18-20. Or 25 years. who knows.
29
How do you determine maturation of bones?
Compare ossification amount on x-ray with a standard
30
Bone is _____ through much of adolescence
Immature -more porous, thick periosteum -Unstable physes/growth plates
31
Changes to muscular system during adolescence
-Muscle size, strength, and endurance increases -Muscle mass increases then body grows -Strength and muscle mass are positively correlated during growth
32
When does muscle diameter reach adult levels?
early teens, 12-15 years
33
Strength increase patterns
Increases linearly with age from 6-18 years Girls: level off after 15 years Boys: accelerates between 13-20 years
34
During adolescence, what happens to the length-tension relationship?
The bones grow faster than the muscles, so the muscles need to lengthen to restore the length-tension relationship
35
Resting pulse and respiratory rate for adolescents
Pulse: 60-90 beats/min Respiratory: 16-24 breaths/min
36
Changes in cardiopulmonary system during adolescence
size of heart and blood volume increase weight and volume of lungs increase
37
Cardiopulmonary system changes during acute exercise in adolescents
-HR is higher during submax and max exercise -Stroke volume is lower -cardiac output is higher -BP is lower at rest, and less dramatic rise during exercise These are to react to the increases in growth/size of the body!
38
Temperature regulation changes in adolescence
-higher surface area to body mass ratio -more metabolic heat/mass unit during physical activities -lower sweating capacity b/c less sweat glands -at low temps lose heat faster This is why teens are at a higher risk of having a cardiac arrest, fainting, or heat injury at high temperatures!
39
What is the appropriate exercise frequency and intensity for adolescents?
3-5 times per week -50-85% of VO2 max normally -40-50% in deconditioned individuals
40
True or false. BMI is a measure that is reflective of physical fitness?
False
41
Psychosocial and behavior changes in adolescence/puberty
-negative attitudes and interactions -self-conscious or low self esteem (potentially b/c of growth spurt) -social antagonism -searching for identity, challenge family values -high emotions
42
Psychosocial changes over time
Young teens (13-14) -self-centered -value peer opinions when they align with their preoccupations Middle teens (15-16) -better at compromising and seeing others' views -think independently, make decisions -risk-taking. focus on present, no consequences -dating Late teens (17-18) -sense of seriousness -ends when taking on adult work roles, marrying, or having children
43
When do adolescents grow in using hypothetical thinking, formal logic, and abstract concepts?
11-14 years
44
Self-esteem trends in adolescents
-initial decline, especially with girls -determined by physical attractiveness, acceptance by peers, academic and athletic ability -peer support is most important for determining esteem during this time
45
Factors of cognitive development
-more relative, less absolute thinking -more self-reflective -considering extended time perspective
46
Suicide is the _____ leading cause of death in youths and young adults
3rd
47
How is depression masked during adolescence?
-anxiety -eating disorders -substance abuse -hyperactivity
48
How can adolescents improve neuromuscular control?
By playing multiple sports Doing the same sport over and over can also lead to higher injury rates
49
How do growth spurts affect adolescent athletes?
The changes in body proportion and length-tension relationship decrease coordination
50
RED-S
Relative Energy Deficiency in Sport Basically, not enough calorie intake or excessive energy expenditure to the point where the body doesn't have enough energy to support its physiological functions Common in adolescent athletes, particularly females
51
PT Implications for RED-S
-decreased muscular strength + endurance -Chronic fatigue -Bone loss can lead to increased risk of fractures -Can lead to stress, depression, and anxiety -Most common in sports like gymnastics and swimming where body shape is emphasized more
52
RED-S was formerly known as ______
Female athlete triad
53
ACL Injuries
-Very common in adolescents, especially females -happens most of the time in sports with cutting/rotating the knee (basketball, soccer, volleyball) -increased risk of OA later in life
54
What often occurs with an ACL injury in adolescents?
Fracture of the growth plate Girls close at 13-15, boys at 15-17
55
Rehabilitation for ACL injuries
Early: range of motion + mobility Gradually: progress to strengthening, endurance, and neuromuscular training (focus on hamstring and glutes) Later: sports-specific activities
