Special Populations and Injury Considerations
Special-population questions reward conservatism: identify the condition, adjust the variables, and know when to refer.
Cardiovascular disease and hypertension. Avoid the Valsalva maneuver and heavy maximal lifts. Emphasize moderate aerobic work, continuous breathing, and RPE-based monitoring. Uncontrolled blood pressure requires medical clearance first.
Diabetes. Exercise improves insulin sensitivity. Watch for hypoglycemia (shakiness, sweating, confusion), especially with insulin or sulfonylureas. Keep fast-acting carbohydrate available, avoid injecting into a limb about to be trained, and inspect feet in clients with neuropathy.
Osteoporosis. Weight-bearing and resistance training are protective, but avoid loaded spinal flexion, twisting, and high fall risk. Emphasize posture, hip and spine extension, and balance.
Pregnancy. With clearance, moderate exercise is generally encouraged. Avoid supine exercise after the first trimester, overheating, contact and fall-risk activity, and the Valsalva.
Older adults and youth. Older clients need longer warm-ups plus balance and power work. Youth training should stress bodyweight skill, technique, and enjoyment with light loads and supervision.
Musculoskeletal. For low back pain favor neutral spine, hip hinging, and core stability. For shoulder impingement limit painful overhead ranges and strengthen scapular stabilizers and external rotators.
Trap: answering train through it or rest completely when the correct response is modify, refer, and document.
Rule of thumb: if exercise can acutely worsen the condition, such as chest pain, dizziness, uncontrolled blood sugar, or acute injury, stop and refer.
