The most common overuse syndromes are tendonitis, tennis elbow, and golfer's elbow. Heel spurs also fall under the category of overuse syndromes in the general sense.

When we move, our joints produce a lubricating substance called synovial fluid. It acts as a cushioning agent, a lubricant, so to speak, and thus ensures smooth movement. It also contains nutrients that nourish the cartilage, thus keeping this protective coating of the joint surfaces alive.
Through regular exercise, we also strengthen our muscles, ligaments, and tendons, and thus the supporting structure that surrounds and stabilizes our joints. Therefore, exercise is important for prevention. However, exercise is also recommended for those with existing conditions (in consultation with a sports physician or orthopedist).

SPORTS
Quick starts and stops, such as those in tennis, should be avoided if you have joint problems. Other ball sports are generally not recommended either, as they often require rapid changes of direction and abrupt movements.
The joints should bear little to no weight, so sports such as skiing or excessive strength training are prohibited. In general, extreme sports, competitive sports, and competitions should be avoided.

TO SWIM
Swimming is considered a cure-all. Whether for knee, hip, shoulder, or ankle problems – the weightlessness of water relieves pressure on the joints and reduces the body weight bearing down on them. Additionally, moving in the water provides a pleasant massage effect, and the water pressure lowers your heart rate. Swimming promotes coordination, endurance, and muscle building. The latter is further enhanced by the water resistance. Front crawl and backstroke are ideal.
Aqua jogging or aqua cycling offer an interesting alternative to swimming. These sports burn approximately 400 calories in 30 minutes, allowing for rapid weight loss if you're overweight. However, you should pay attention to the correct technique.

Weak connective tissue can be not only visible externally, but can also occur throughout the body in a wide variety of organs. Weak connective tissue can no longer properly fulfill its function of providing shape and support and loses elasticity. Its ability to glide and slide also decreases.
The slightly weakened fibers in the connective tissue can lead to sagging of the outer skin and blood vessels, as well as to a loosening of the anchorage of internal organs. This is visible externally as stretch marks. Dilated vessels cause varicose veins, and the diminished support function leads to organs no longer being able to stay exactly where they should be and therefore sagging or dislocating, as is the case with uterine prolapse.
Excessive amounts of metabolic toxins can sometimes lead to hardening of the connective tissue, accompanied by pain in joints, myogelosis (palpable hardening, thickening in the muscles), recurring tension and allergies.

CAUSES OF CONNECTIVE TISSUE WEAKNESS
In general, women are more prone to connective tissue weakness than men. This is due to the different arrangement of connective tissue structures. In women, these structures are parallel. Regardless of gender, obesity, lack of exercise, and an unhealthy diet can promote the development of connective tissue weakness.

Nutrition also affects connective tissue. In connective tissue, too, there is a constant, lively exchange between cells and blood.

Consequences of often one-sided strain or excessive strain can include tendonitis and tennis or golfer's elbow. Heel spurs are also generally considered an overuse syndrome.

The range of substances that are supposed to help is difficult for many customers and interested parties to keep track of.

Alleged test sites are of no help here, as the beautifully designed reports are almost always just paid advertising. We are frequently contacted about this opportunity to increase sales, but we consistently reject it.
If in doubt, always check the imprint to see who's behind the product. There are many surprises (e.g., The Pharmacy Guide). We prefer to invest in the quality of our raw materials rather than in purchased reviews and paid advertising.

Check who you trust and whether the advertising claims for dietary supplements (almost always illegal) actually deliver what they promise.
