Pregnancy - Concerns with exercise

- 02 or nutrient availability for both exercising muscle of mother and fetus - hyperthermia-induced fetal distress or birth abnormalities - Increased uterine contraction

Pregnancy Exercise Prescription - Resistance Training

- 2 - 3 nonconsecutive d/wk - 8-10 or 12 - 15 reps to point of moderate fatigue - 1 set for beginners, 2 - 3 sets for intermediate

Cardiac - Resistance Training

- 2-3 days/week (nonconsecutive) - 10-15 reps, RPE 11-13 (40-60% 1 RM) - 1-3 sets, 8-10 exercises, focus on major muscle groups, avoid breath holding.

- Before meals: 90-130 mg/dl - 1.5 - 2 hours after meal: 100-160 mg/dl - Bedtimes:100 - 140 mg/dl

Pulmonary Overview:

- COPD: Chronic Obstructive Pulmonary Disease - Obstructive Pulmonary conditions obstruct airflow within the lungs leading to less resistance to inspiration and more resistance to expiration.

Diabetes - Diagnosis

- Fasting blood glucose > 126 mg/dl - symptoms plus casual plasma glucose > 200 mg/dl - 2-hr glucose > 200 mg/dl during an oral glucose tolerance using 75 gram glucose load

Pregnancy Exercise Testing

- Maximal is not recommended (unless is a clinical condition which warrants it). If warranted, the test should only be performed with physician supervision after have checked for contraindications to exercise. - Assumptions for submax tests may be compromised (use to chart progress rather than expect accurate estimate of aerobic fitness.

Pulmonary Exercise Testing

- Measure exercise capactiy and exercise tolerance - Measure disease progression and treatment response - Determine other reasons for dyspnea and or exercise limitations - may need to modify protocol (smaller increments, slower progression) - 8-12 min or duration 5 - 9 minutes for those with more severe disease

Diabetes - Resistance Training

- minimum of 2, but preferably 3 nonconsecutive d/wk - 1-3 sets of 10-15 reps early in training and progress to heavier weights using 1-3 sets of 8-10 reps -moderate (50-69% 1 RM) to vigorous (70-85% 1 RM) - exercises including all major muscle groups - Complete resistance training prior to aerobic to lower risk of hypoglycemia for those with T1DM

cardiac disease

- plaque forming on the inside of the coronary vessels can rupture allowing clot formation to occur, potentially blocking the vessel. - chest discomfort - It is typical angina if all 3 components are present, if only two then atypical angina, which is more common in women. -Location and type of sensation. If it occurs with myocardial stress - If it is relieved by nitroglycerin or rest.
