Describe special considerations for children
•Children and adolescents may safely participate in strength training activities provided they receive proper instruction and supervision. Generally, adult guidelines for resistance training may be applied. •Because of immature thermoregulatory systems, youth should avoid exercise in hot humid environments, be properly hydrated, and appropriately modify activities. •Efforts should be made to decrease sedentary activities (i.e., television watching, surfing the Internet, and playing video games) and increase activities that promote lifelong activity and fitness (i.e., walking and cycling).
Describe exercise prescription in children
•Children and adolescents should be encouraged to participate in various physical activities that are enjoyable and age appropriate. •PA in young children should include unstructured active play, which typically consists of sporadic bursts of moderate- and vigorous-intensity PA alternating with brief periods of rest. -These small bouts of PA, however brief, count toward FITT recommendations.
Describe exercise prescription for patients with LBP (5 points) (may want to break it up)
•Clinical practice guidelines for the management of LBP consistently recommend staying physically active and avoiding bed rest. •Individuals with subacute and chronic LBP as well as recurrent LBP are encouraged to be physically active. •When recommendations are provided, they should follow very closely the recommendations for the general population combining resistance, aerobic, and flexibility exercise. •In chronic LBP, exercise programs that incorporate individual tailoring, supervision, stretching, and strengthening are associated with the best outcomes. •For the most favorable outcomes, use an individualized approach that addresses psychological distress, fear avoidance beliefs, self-efficacy in controlling pain, and coping strategies.

Describe physiologic responses to exercise in young individuals
•Physiologic responses to acute, graded exercise are qualitatively similar to those seen in adults. -There are important quantitative differences, many of which are related to the effects of body mass, muscle mass, and height. -Children have a much lower anaerobic capacity than adults, limiting their ability to perform sustained vigorous intensity exercise.

•The exercise testing protocol should be based on the reason the test is being performed and the functional capability of the child or adolescent. •Children and adolescents should be familiarized with the test protocol and procedure before testing to minimize stress and maximize the potential for a successful test.
What happens to the heart during pregnancy
•The heart is displaced laterally - you may see ECG changes.
What are indications to terminate a test for older adults?
•The increased prevalence of cardiovascular, metabolic, and orthopedic problems among older adults increases the overall likelihood of an early test termination.
Describe the elderly and their medications during ET
•The influence of prescribed medications on the electrocardiographic (ECG) and hemodynamic responses to exercise may differ from usual expectations.
Describe the workload and protocol for ET in older adults
•The initial workload should be light (<3 metabolic equivalents [METs]) and workload increments should be small (i.e., 0.5-1.0 MET) for those with low work capacities. The Naughton treadmill protocol is a good example of such a protocol.
What is a 1 RM test?
•The maximal amount lifted once, but not twice, with proper technique (no straining, full extension)
What happens during Osgood-Schlatters disease?
•This disease is caused by repeated stress on the top of epiphysis plate of tibia, just below the patella, where the quads are inserted into tibia.
Describe blood volume during pregnancy
•This increase in blood volume also increases SV and Q (Q may increase 40%--average ~ 1500 mL).
Why else do you Need to Perform Strength Testing for Our Special Population Patients?
•To help determine the patient's ability to perform basic ADL's (walking, dressing, picking things up, housework, squatting) • To measure individual success in resistive exercises with validated norms • To boost confidence and self-efficacy • To help assess posture and balance issues and to prescribe posture and balance exercises • To assess and determine the individual needs of the patient with respect to their unique overall muscular weaknesses and develop their exercise Rx
If you have LBP, what should you do?
•To reduce the probability of disability, individuals with LBP should stay active, continue ordinary activity within pain limits, avoid bed rest, and return to work as soon as possible.
Should the speed be modified for elderly ET?
•Treadmill workload may need to be adapted according to walking ability by increasing grade rather than speed.
Describe exercise testing on children
•Treadmills and cycle ergometers should be available for testing. •Treadmills tend to elicit a higher peak oxygen uptake (VO2peak) and maximum HR (HRmax). •Cycle ergometers provide less risk for injury and are more stable, but need to be correctly sized for the child or adolescent. •Children and adolescents may require extra motivation and support during the exercise test compared to adults.
What is a good way to know if children get enough daily activity?
•Using pedometers + accelerometers may be helpful •60 minutes/day = ~ 9,000-12,000 steps/day
Should you VO2 max test during pregnancy?
•VO2max testing not recommended (unless medically necessary) •Not used to estimate maximal aerobic power due to pregnancy-induced changes •Physician present
What are some signs to terminate exercise during pregnancy
•Vaginal bleeding •Dyspnea prior to exertion •Dizziness, syncope, or headache •Chest pain •Muscle weakness •Calf pain/swelling •Preterm labor •decrease Fetal movement •Amniotic fluid leakage
Describe ventilation during exercise
•Ventilation increases due to elevated progesterone, which decreases CO2 via hyperventilation and increases MV (up to 50%).
Is it safe to administer vigorous exercise to young individuals?
•Vigorous exercise can be initiated after safely participating in moderate exercise. -Because prepubescent children have immature skeletons, younger children should not participate in excessive amounts of vigorous intensity exercise. -Obese children are definitely at higher risk of multiple diseases over time!
Look at these practice questions for material of children and testing
•Which metabolic pathway is less efficient in children than adults? •Why do children need heat acclimatization longer than adults? •Is cardiac output and stroke volume higher or lower in children than adults? Why? •Name a TM protocol for children. •Is the traditional RPE scale good for children? •Name one special exercise testing consideration for children. •Name 2 contraindications to exercise for children.
Is there a optimal frequency of exercise during pregnancy?
•While there is no ideal number of days, exercise frequency during pregnancy should be regular, occurring throughout the week, and adjusted based on total exercise.
Should a physician be consulted before resuming exercise after pregnancy
•Women who are pregnant and severely obese and/or have gestational diabetes mellitus or hypertension should consult their physician before beginning an exercise program and have their Ex Rx adjusted to their medical condition, symptoms, & physical fitness level.
Are contact sports allowed during pregnancy?
•Women who are pregnant should avoid contact sports and sports/activities that may cause loss of balance or trauma to the mother or fetus.
If you resistance train before pregnancy, should you continue while pregnant?
•Women who habitually participate in resistance training should continue during pregnancy and should discuss how to adjust their routine with their health care provider.
