Abstract

A mobile swimming training device and means of locomotion, characterized in that the trainee is comfortably on a padded lying surface, which in turn is connected to a frame with rollers, so that the full mobility of bilateral or alternating swimming movements of the arms leads to active locomotion of the Exercising along with a swimming scooter comes.

Description

With the invention of the swimming scooter, a swimming training device and means of locomotion is created in which the trainee actively moves on land by activating the swimming muscles in parallel with both arms (dolphin swimming) or alternately (crawl swimming). This happens when the athlete lies comfortably on a padded pad from the upper part of the torso to the knees on the stomach side. This padded layer allows the athlete to lie with sufficient freedom of movement of the arms during the training period. The focus can thus be placed completely on locomotion by activating the swimming muscles. The swimming scooter can be steered by two moving wheels at the front. Since the swimming scooter is a purely mechanical training device without a drive, steering, movement and braking are carried out exclusively using the arms or hands. Appropriately padded gloves must be worn on the hands to protect against injury/abrasion with the ground/asphalt. The athlete determines the training effect by varying the pull (different use of force), frequency or the total duration. As with the actual swimming training, the aspects of strength, endurance, speed or a combination of these can be trained.

A length of 1m, a width of 30cm and a height of about 40cm (note: about 40cm, since the height varies due to the pressing of the upper body on the padding) were specified for the dimensions of the swimming scooter. Experiments with different people and other dimensions have shown that these dimensions are optimal. For extremely small or large athletes, the swimming roller would have to be adjusted accordingly.

There was a problem for swimmers and triathletes, especially during the pandemic and the associated swimming pool closures, to find an almost equivalent training option for training the swimming muscles. For many athletes, the well-known static training methods with pull ropes are at most a training supplement, since long-term motivation is often low here.
Another problem with swimming training is the relationship between time and benefit (efficiency of gross training time versus actual training time in the water). At the time of training in the water, you have to reckon with a journey changing time with showers x 2 and a return journey.

With the swimming scooter, the training can be started directly with optimal living/starting conditions (flat path, little frequented by cars or bike path). There is an optimal training effect in relation to the time investment.

Since the athlete moves actively and mobile with the swimming scooter, there is a greatly increased long-term motivation, which in turn leads to better training results. The training could be held with several people/swimming scooters, which also serves as a long-term motivation.

State of the art

In swimming/triathlon, dry/land training plays an important role. Motion sequences can be optimized and rehearsed more intensively. Furthermore, the strength efficiency can be better increased during land training. The athlete can concentrate more specifically on the training of the corresponding muscle groups, since aspects such as position in the water, orientation or being in another element (water) are omitted.

There are known training devices in the water, such as swimming gloves or paddles, the purpose of which is to increase the resistance and thus the strength component in the underwater phase.

On land there are static options using pull ropes/pulling rope devices, which the exerciser operates either standing or lying down, to address the swimming muscles and to promote strength or endurance, also depending on the strength of the pulling ropes or an adjustable resistance
The rope training method on land is not mobile, the athlete remains in one place.

Explanation drawing swimming roller

The drawing shows the swimming scooter without padding.

The trainee lies on his stomach on the lying surface, in practice with padding, which is firmly connected to the steel of the lying surface with Velcro straps.

The athlete's chest is level with the swiveling front steering wheels, and the knees rest comfortably on the padding at the back. When the athlete pulls his arms down and forwards on a flat surface that is as well asphalted as possible, either simultaneously (dolphin arm pull) or alternately (crawler arm pull) and then backwards over the asphalt, the movement of the swimming roller is created.
