For back and joint complaints, whether acute or chronic, medical training therapy in water (hydrotherapy) is, in my view, the most suitable.
Here, crawl swimming (back and breast), aqua jogging and aqua gymnastics should be mentioned, which offer the following advantages.
Improvement of coordination
Due to the buoyancy, movement sequences can be practised and mastered with the use of less muscle strength.
Muscular relaxation
Muscle tension is reduced by the buoyancy and the resulting weight loss (up to 1/7). A water temperature of 31° – 36°C is ideal here.
Relief for the joints
As the water depth increases, the pressure on the joints decreases. For example, if a person is standing in water up to their chest, only 15-30 kg of weight will be on their joints. Bone fractures that have healed with a scar after surgery but are not yet stable can be treated and the surrounding muscles can be strengthened.
Pain reduction
Due to the buoyancy, the relief of the joints and the reduction of the muscle tone, affected body regions no longer hurt or hurt much less. This also increases motivation for training.
Joint mobility
The buoyancy can improve joint mobility in cases of arthrosis or capsular ligament injuries, among others. The mobilisation of the affected joints is promoted by constantly changing the direction of movement in the sense of the principle of force (actio) and counterforce (reactio).
Muscle building training
With the help of the flow resistance, a very differentiated muscle building training, i.e. training of specific muscle groups, is possible.
Improving dynamic strength
Depending on the number of repetitions of a movement and the increase in movement speed, a steady increase in muscle strength is achieved.
Improving balance and stabilisation
The body must be kept stable during short, fast arm movements.
Can be done very inexpensively with little effort in a swimming pool or lake all year round.
