Swimming, Exercise Guidelines for Women and Elderly Patients with Hyperlipidemia

Swimming – A sport that benefits both mind and body

Swimming is the first skill people learn to play in the water, and it's popular worldwide, being one of the most common fitness activities. Swimming is a full-body exercise, actively engaging almost all muscle groups and internal organs, thus increasing the function of various organs and systems and providing comprehensive physical training. Swimming requires the coordinated operation of all the body's motor organs, ensuring balanced development from skin to internal organs, and from upper limbs to lower limbs. Swimming involves involuntary breathing under water pressure, and the relative increase in carbon dioxide in the body stimulates stronger breathing, thus not only exercising the respiratory muscles but also increasing lung ventilation. Swimming improves the heart's pumping function and oxygen transport capacity, and lowers diastolic blood pressure. This is because swimming enhances the vascular reflex regulation of the autonomic nervous system, thereby reducing peripheral vascular resistance. Swimming improves aerobic metabolism. Swimming is a series of complex movements performed under the control of the brain; swimming exercise can improve brain function, promote the brain's responsiveness to the external environment, and enhance intellectual development. Swimming is one of the most effective means of improving the body's resistance to disease and immune function, enhancing the body's adaptability to the external environment.

After years of follow-up investigations and research by numerous medical experts and sports scientists, it has been found that among various weight loss methods, exercise is the safest and most effective; and among various exercises, swimming is the most ideal for weight loss. Experts point out that the most important aspect of fighting obesity is increasing the body's energy expenditure. Because water's thermal conductivity is five times that of air, and the resistance of water is much greater than that of air during swimming, the calories burned while swimming far exceed those of many land-based sports. In particular, long, slow swimming can consume energy derived from fat, thereby accelerating weight loss. According to relevant research, swimming is a relatively fast, safe, and reasonable way to lose weight.

When swimming, please pay attention to the following aspects:

First, a physical examination must be conducted before swimming. Anyone with tuberculosis, infectious hepatitis, bacterial dysentery, purulent otitis media, severe cardiovascular disease, conjunctivitis, skin disease, mental illness, or open wounds should not swim.

Secondly, it's essential to warm up before swimming. This can increase the excitability of the nervous system, accelerate blood circulation and metabolism, increase muscle strength and elasticity, expand the range of motion of joints, improve flexibility, and prevent cramps. Warm-up exercises can include calisthenics, running, and various exercises that lengthen muscles and ligaments.

Third, swimming is not advisable after meals or when hungry. Swimming immediately after a meal causes the chest cavity to expand, the diaphragm to tense, and the abdominal muscles to contract, thus shrinking the abdominal cavity. The stomach and intestines are compressed by the abdominal wall and the water, easily causing food to reflexively regurgitate upwards. Mild cases may result in hiccups while swimming, while severe cases may lead to vomiting, stomach cramps, and abdominal pain. Therefore, it is advisable to swim one hour after a meal. Swimming on an empty stomach is also not recommended, as it can easily lead to hypoglycemia.

Fourth, do relaxation exercises after swimming. Dry yourself off immediately after swimming to avoid catching a cold, and do relaxation exercises or limb movements to help relieve fatigue.

Lipid-lowering effects vary from person to person.

How should women with high cholesterol exercise?

Exercise therapy for women with hyperlipidemia should take into account their physiological characteristics. For women with hyperlipidemia, physical exercise is beneficial for weight loss and lipid reduction. It can also strengthen overall physical strength and endurance, and strengthen pelvic and abdominal muscles, which is helpful in maintaining the normal position of the internal reproductive organs and preventing gynecological diseases such as uterine prolapse and abnormal uterine position.

Women should choose exercise for weight loss based on their age and personal interests. Younger women can choose walking, swimming, martial arts, gymnastics, hula hooping, etc.; middle-aged women can consider walking, Tai Chi, Baduanjin (Eight Pieces of Brocade), cycling, etc., with walking being the most suitable for weight loss. Some researchers conducted a monitoring study on people who exercised by walking and found that walking for 20 minutes at a speed of 4.8 kilometers per hour, about 45 minutes after a meal, burns calories quickly and is most beneficial for weight loss. If you can walk again 2-3 hours after a meal for about 20 minutes, the effect will be even better. In addition, joining a fitness club to practice fat-reducing, weight-loss, and aerobics is also an excellent choice.

How should elderly patients with high cholesterol exercise?

The exercise of elderly patients with hyperlipidemia is different from that of middle-aged and young people. Obese elderly people often have coronary heart disease, hypertension, fatty liver, etc. Due to their obesity and clumsiness, coupled with their eagerness to lose weight through exercise, improper exercise may lead to accidents.

For elderly patients with hyperlipidemia, exercise should only be undertaken after a doctor's examination and confirmation. If they are in good physical condition, they can perform a self-check, such as squatting 10-20 times consecutively or jogging in place for 15 seconds without experiencing shortness of breath or chest discomfort. It is best to participate in group exercise or have someone accompany them. Patients should carry emergency medication or a health record card to understand their condition and administer medication promptly in emergencies. The amount of exercise should be gradually increased, and the speed should not be too strenuous. Appropriate exercise is characterized by feeling warm and slightly sweaty during exercise, feeling relaxed and comfortable after exercise, and good sleep. If the heart rate exceeds 100 beats per minute, rest intermittently. 30-40 minutes of exercise per day is sufficient. If dizziness, chest tightness, palpitations, poor sleep, or significant fatigue occur, it indicates excessive exercise. The principle of gradual progression should be followed, starting slowly and gradually increasing the speed, from easy to difficult, and from simple to complex, gradually increasing the time. Before exercising, warm up slightly, focusing on whole-body exercises and avoiding overexertion of any one limb or organ. Suitable activities include walking, jogging, Tai Chi, Baduanjin (Eight Pieces of Brocade), local massage, sunbathing, and medicinal baths. During exercise, breathe naturally and evenly, paying attention to abdominal breathing; avoid holding your breath or excessive exertion, and refrain from inverted postures, sudden forward or backward leaning, or rapid rotations to prevent falls or accidents. Avoid fast running and prolonged exercise. Choose early morning for exercise, and rest appropriately afterward, ensuring good sleep to promote a healthy cycle.
