Q

health and safety considerations

A

strength and conditioning professional must:
-be aware of testing conditions that can threaten the health of athletes

  • be observant of signs and symptoms of health problems that warrant exclusion from testing
  • remain attentive to the health status of athletes, especially before, during and after max exertions
38
Q

selection and training of testers

A

-should be well trained
-should have a thorough understanding of all testing procedures and protocols
-should perform and score all tests correctly
-must have sufficient practice
-should be trained to explain and administer the tests as consistently as possible

39
Q

recording forms should:

A

Scoring forms should be developed before the testing session and should have space for all test results and comments.

40
Q

test format

A

-consider whether athletes will be tested all at once or in groups
-the same tester should administer a given test to all athletes if possible
-each tester should administer only one test at a time, especially when the tests require complex judgments

41
Q

testing batteries and multiple testing trials

A

-duplicate test setups can be used for large groups
-when multiple trials of a test or a battery of test are performed, allow complete recovery btw trials

42
Q

sequence of tests

A

Knowledge of exercise science can help determine: proper order of tests and the duration of rest periods
between tests to ensure test reliability.
The fundamental principle with test sequencing should be that one test should not affect the performance of a subsequent test

43
Q

sequence of tests 1 to 7

A
  1. Nonfatiguing tests (height, weight, flexibility, skinfold and girth measurements, balance and stability, vertical jump)
  2. Agility tests (T-test, pro agility test, Edgren side step test)
  3. Maximum power and strength tests (1RM power clean, 1RM bench press)
  4. Sprint tests (40 m sprint with split times at 10 m and 20 m)
  5. Local muscular endurance tests (partial curl-up test, push-up test)
  6. Fatiguing anaerobic capacity tests (400-m run, 300-yard shuttle run)
  7. Aerobic capacity tests (1.5-mile run, 12-min run or Yo-Yo intermittent recovery test)
44
Q

what should the test order be designed to require

A

The test order should also be designed to require minimal recovery time between tests, allowing for a more efficient testing session

45
Q

how to prepare athletes for testing

A

-announce time, date and purpose of test battery in advance
-athletes should be familiar w test content and procedures
-host a short, supervised pretest practice or familiarization session 1 to 3 days before the test
-provide clear and simple instructions

46
Q

what should the instructions cover for prep of athlete for testing

A

the purpose of the test, how it is to be performed, the amount of warm-up recommended, the number of practice attempts allowed, the number of trials, test scoring, criteria for disallowing attempts, and recommendations for maximizing performance.

47

50
Q

aerobic endurance testing in the heat

A
51
Q

what is hyponatremia

A

Hyponatremia occurs when the concentration of sodium in your blood is abnormally low

52
Q

What is EAH used to describe?

A

EAH is used to describe hyponatremia occurring during
or up to 24 hours after physical activity

53
Q

What is the definition of EAH?

A

Exercise-associated hyponatremia (EAH) is defined by an acute fall in the serum or plasma sodium concentration to below 135 mmol/L that occurs during or up to 24 hours after prolonged physical activity.

54
Q

What are the main determinants of serum [Na+]

A

the total content of exchangeable body sodium and potassium
relative to total body water

55
Q

What are 3 ways EAH can occur?

A

from loss of solutes (sodium, potassium), a relative excess of
total body water or a combination of both

56
Q

Which of the 3 exercise-associated hyponatremias are classified dilutional and depletional EAH?

A

Hypovolemic EAH

57
Q

What are the 2 forms of EAH

A

asymptomatic or symptomatic

58
Q

What are the major risk factors for the development of asymptomatic and symptomatic EAH?

A

-Overdrinking water, sports drinks, and other hypotonic beverages
-Weight gain during exercise
-Exercise duration >4 h
-Event inexperience or inadequate training
-Slow running or performance pace
-High or low body mass index (BMI)
-Readily available fluids

59
Q

What is the single most important risk factor for EAH?

A

The single most important risk factor is sustained, excessive fluid (water, sports drinks or other hypotonic fluids) intake in volumes greater than loss through
sweat, respiratory and renal water excretion so that a positive
fluid balance accrues over time

60
Q

Which form is the most dangerous to an athlete’s health?

A

Severe symptomatic EAH (EAHE)

61
Q

What is arginine vasopressin (AVP)

A

Vasopressin (arginine vasopressin [AVP]), also known as antidiuretic hormone (ADH), is a nonapeptide stored in and secreted from the posterior pituitary gland. Its primary target organ is the distal convoluted tubule and collecting duct, where it acts to promote water reabsorption

62
Q

What is another name for AVP?

A

anti-diuretic hormone secretion (SIADH)?????

63
Q

What is non-osmotic AVP secretion?

A

non-osmotic AVP secretion is a key contributing factor in most athlete-related symptomatic cases.5,19
Known stimuli to AVP secretion that are commonly associated with exercise include: nausea/vomiting;
interleukin-6 release; plasma volume contraction; hypoglycemia; elevated body temperature; and/or other hormonal mediators

64
Q

What is SIADH?

A

syndrome of inappropriate anti-diuretic hormone secretion (SIADH)

65
Q

How is non-osmotic AVP secretion different from osmotic AVP secretion?

A

the threshold and sensitivity of AVP release

66
Q

What is EAHE

A

exercise-associated hyponatremic encephalopathy
a life-threatening
condition that has been observed across a wide variety of
activities

67
Q

What is the difference between asymptomatic and symptomatic EAH

A

Asymptomatic athletes with [Na+]135 mmol/L have largely been detected
by blood samples taken post-exercise from athletes participating in research protocols or obtained for reasons other than suspicion of EAH. Athletes with the symptomatic form
of EAH can present with mild, non-specific symptoms
(eg, lightheadedness, nausea) but typically present with
headache, vomiting, and/or altered mental status (eg, confusion, seizure) resulting from cerebral edema

68
Q

In which activities has Symptomatic EAH been reported?

A

Clusters of cases have occurred
in military training exercises, marathons, Ironman triathlons
and ultramarathons

69
Q

What are the etiology & pathophysiology of EAH

A

The predominant pathophysiology of EAH, and of most
serious medical concern, is dilutional hyponatremia caused by
sustained overdrinking and AVP induced impaired water
clearance, which overwhelms the ability of the kidney to
excrete the excess water load

70
Q

What are the etiologies of the 3 types of EAH

A

-euvolemic (total body water expansion without changes in total exchangeable sodium)
-hypervolemic (total body water expansion above concomitant increases in total exchangeable sodium)
-hypovolemic hyponatremia reflects a loss of total body exchangeable sodium that manifests as volume
depletion

71
Q

What is the role of thirst?

A

Thirst should provide adequate stimulus for preventing
excess dehydration and markedly reduce the risk of developing EAH in all sports

72
Q

What is the misconception of thirst as a guide to fluid replacement?

A

Unfortunately, this advice has fostered the misconception that thirst is a poor guide to fluid
replacement and has facilitated inadvertent overdrinking and
pathological dilutional EAH

73
Q

Is EAH best classified by clinical severity or by the absolute numerical concentration of Na+?

A

e, EAH is best classified
by clinical severity (symptoms) and not the absolute numerical [Na+] value to best guide treatment strategies

74
Q

What are the signs & symptoms associated with Mild EAH, and Severe EAH & EAHE (Table 5)?

A
75
Q

Do the signs & symptoms of EAH overlap with other conditions associated with exercise-associated collapse?

A

yes

76
Q

What are some of these other causes of collapse?

A

signs and symptoms
including exertional heat illness, acute mountain sickness,
hypernatremia and exercise associated postural hypotension

77
Q

what is orthostatic hypotension

A

also called postural hypotension — is a form of low blood pressure that happens when standing after sitting or lying down

78
Q

What is the Trendelenburg position?

A

the patient is supine on the table with their head declined below their feet at an angle of roughly 16

79
Q

What is obtundation, decorticate posturing, mydriasis, and frothy sputum?

A

obtundation: A dulled or reduced level of alertness or consciousness

decorticate posturing: an abnormal posturing in which a person is stiff with bent arms, clenched fists, and legs held out straight

mydriasis:Dilated pupils

frothy sputum:Mucus that contains bubbles and is foamy

80
Q

What is osmotic demyelination syndrome?

A

a condition that is associated with rapid correction of sodium levels or fluid shifts

81
Q

What is non-cardiogenic pulmonary edema?

A

Pulmonary edema that is not caused by increased pressures in the heart

82
Q

What is the cause of neurological signs & symptoms of severe symptomatic EAH?

A

due to cerebral edema that
occur when water flows along the osmotic gradient from the
extracellular fluid into the intracellular compartment

83
Q

Is severe symptomatic EAH always accompanied by CNS-triggered non-cardiogenic pulmonary edema?

A

no it may or may not

84
Q

What are the onsite treatments for Asymptomatic & Symptomatic EAH?

A

In athletes with this incidental biochemical diagnosis, oral or intravenous hypotonic fluid intake should be restricted until the onset
of urination
life threatening emergency that requires immediate administration of IV hypertonic saline (HTS)

85
Q

What is HTS?

A

IV hypertonic saline such as sodium chloride

86
Q

What is the concentration range for HTS?

A

The dose and route of
HTS administration should be based upon the severity of
clinical symptoms and the available HTS formulations

87
Q

What are the recommended treatments for Mild or Severe EAH (Table 6)?

A
88
Q

What is the treatment for athletes with signs & symptoms of EAHE?

A

will require immediate
measurement of electrolytes and should be treated as
described above without delay once EAH is confirmed

89
Q

What are the 3 types of fluids that can worsen the degree of hyponatremia?

A

(water, sports drinks or other hypotonic fluids)

90
Q

how can EAH be oprevented?

A

The drinking of fluid volumes sufficiently above
sweat and urinary losses before, during and after activity and
the accrual a positive water balance, is the primary underlying pathophysiological mechanism of symptomatic and fatal
EAH cases

91
Q

According to laboratory and field studies, what percentages of normal body mass and total body water can be tolerated without a reduction in endurance performance or muscular power when in cool to temperate temperatures?

A

Laboratory and field studies indicate that fluid deficits less
than and up to a volume approximately equal to 3% of normal
body mass (or ;5% total body water) can be tolerated without a reduction in endurance performance or muscular power
when in cool to temperate (2108C-208C) temperatures

92
Q

In most cases, will drinking to thirst prevent both dilutional EAH & performance decrements due to excessive dehydration?

A

Therefore, aggressive drinking to prevent dehydration is
unnecessary and carries with it greater risk of developing
symptomatic EAH.
