Exercise prescription is a systematic exercise plan developed by healthcare professionals based on the patient's physical condition and health goals. Its core purpose is to improve chronic diseases, promote functional recovery, or prevent disease progression through scientifically designed exercise programs. This therapy combines personalized assessment with evidence-based medicine principles to effectively enhance patients' cardiopulmonary function, muscle strength, and metabolic regulation capabilities.
Exercise prescriptions mainly include four categories: aerobic exercise, resistance training, flexibility training, and balance training. Aerobic activities such as jogging or swimming stimulate cardiovascular adaptations, promoting mitochondrial growth and angiogenesis. Resistance training increases muscle mass through weight-bearing exercises, boosting basal metabolic rate and bone density. The physiological mechanisms involve inducing antioxidant enzyme activity, regulating insulin sensitivity, and promoting neuromuscular coordination.
This therapy is suitable for patients with metabolic syndrome, cardiovascular diseases, type 2 diabetes, osteoporosis, and other chronic conditions. For rehabilitation needs, such as post-arthroplasty patients, tailored rehabilitation exercises can be designed to restore activity levels. Obese patients can effectively improve body fat ratio and hepatic fat accumulation through structured exercise prescriptions. Special populations like the elderly or pregnant women need to adjust intensity to prevent falls or pregnancy complications.
The implementation of prescriptions follows the FITT principles: Frequency (sessions per week), Intensity, Time (duration), and Type (kind of exercise). For example, a diabetic patient might be recommended to perform moderate-intensity aerobic exercise for 30 minutes, five times a week. The dosage should be adjusted based on the patient's fitness level, starting at 50-60% of maximum heart rate and gradually increasing to the target level. Regular re-evaluation through fitness testing is necessary to update the prescription.
Long-term adherence can improve cognitive function and delay brain atrophy. It also benefits mental health by promoting endorphin secretion, alleviating symptoms of depression.
Important Warning: If chest pain, dizziness, or abnormal fatigue occurs during exercise, stop immediately and seek medical attention.
Contraindications include acute myocardial infarction, uncontrolled hypertension (>180/110 mmHg), and acute arthritis. High-risk groups should exercise under supervision; for example, those with implanted pacemakers should avoid vigorous movements. Pregnant women should avoid supine exercises, and preeclampsia patients should limit intensity.
When combined with blood glucose-lowering medications, dosage adjustments are necessary to prevent hypoglycemia. Caution is advised when used with anticoagulants due to changes in coagulation function caused by exercise. In rehabilitation, exercise prescriptions can synergize with physical therapy but should avoid conflicts with joint immobilization devices. Patients undergoing psychological therapy may benefit from exercise-induced endorphin effects to enhance outcomes.
Studies show that regular adherence to exercise prescriptions can reduce HbA1c by an average of 0.5-1.0% in type 2 diabetes patients. Cardiovascular patients can increase maximum oxygen uptake (VO2 max) by 15-20% after six months. Osteoporosis patients may see a 1-3% increase in bone mineral density with resistance exercises. Clinical guidelines recommend incorporating exercise prescriptions into first-line hypertension treatments.
For patients unable to exercise, options include intermittent fasting or metabolic enhancement therapies. Severe joint issues may be managed with aquatic exercises or electrical stimulation training. Pharmacological treatments such as GLP-1 receptor agonists are first-line options for metabolic diseases but require attention to gastrointestinal side effects.
When creating an exercise prescription, physicians assess factors such as age, physical fitness level, health status (e.g., cardiopulmonary function, muscular endurance), chronic disease history (e.g., hypertension, diabetes), and personal lifestyle (e.g., work nature, leisure time). Additionally, contraindications (e.g., joint discomfort) or past injury history are considered to ensure the safety and appropriateness of exercise intensity and type.
How should I respond if I experience muscle soreness or joint discomfort during exercise?If mild muscle soreness occurs after exercise, applying cold or hot packs, stretching, or low-intensity activity can help alleviate symptoms. If joint pain persists or worsens, stop the current exercise immediately and consult a doctor to adjust the exercise plan. Do not self-medicate with painkillers or force training, as this may cause tissue damage or chronic inflammation.
How can patients with chronic diseases (such as diabetes) safely perform exercise prescriptions?Patients with chronic diseases should confirm target heart rate ranges and blood glucose monitoring frequency with their physician before exercising. For example, diabetic patients should check blood sugar before and after exercise to avoid hypoglycemia and choose low-impact activities like aquatic exercise. It is recommended to schedule exercise 1-2 hours after medication intake and adjust medication doses based on individual response.
How long does it take to see the effects of an exercise prescription?Generally, after 6-8 weeks of regular exercise, improvements in cardiopulmonary function, muscle strength, or blood glucose control can be observed. Progress varies based on individual baseline fitness, and should be combined with dietary control and regular health assessments. Physicians will adjust exercise intensity or type based on follow-up data to ensure continued progress.
How to cope if time constraints prevent completing the exercise prescription?You can negotiate with your physician to split the exercise sessions, such as breaking down 30 minutes of moderate-intensity exercise into three 10-minute sessions. Walking during commuting, home stretching, or resistance training during fragmented time are alternative options. The key is maintaining consistency; completing all exercise time in one session is less important. Physicians can help plan flexible schedules based on actual circumstances.
