Description

Sports aid for running

Field of technology

The invention relates to a sports aid for running in summer and winter, in the form of two multi-purpose poles, one for each hand.

Prior art

Running is an ideal and highly effective physical activity for improving a person's endurance condition and reducing extra pounds. Unlike other physical activities of an endurance nature, running is relatively physiologically demanding due to the involvement of a large number of muscle groups. Due to the need to depreciate gravitational forces during impacts, the musculoskeletal system is often significantly loaded during running - especially the supporting joints. The effort of sports doctors and scientists is therefore to eliminate the orthopedic risk while maintaining the high physiological effectiveness of this physical activity. When looking for a new alternative physical activity, a certain developmental analogy can be seen in the origin of Nordic Walking, ie fitness walking with sticks. With the relatively mass development of fitness walking, practice has shown the need for increased support, greater stability and relief of the musculoskeletal system consisting of fitness walking with sticks. When comparing Nordic Walking with standard walking, the use of sticks and the involvement of the arms results in a partial relief of the supporting joints of the lower limbs - ankle, knee, hip. During this activity, however, with the use of standard sticks, its higher intensity is not possible, which is essential for the effective implementation of some training goals.

Running, Nordic Walking, fitness walking and cross-country skiing can be considered as widespread and methodically processed physical activities. However, none of the mentioned activities methodically or in terms of equipment meets the specifics of the new physical activity - running with sticks, resp. its summer and winter variant, for which the new sports equipment is intended.

These are mostly endurance movement activities, during which individual movement structures - steps - are cyclically repeated. The advantage of running and cross-country skiing is the possibility of achieving relatively high efficiency of physical activity, both in terms of training goals and, for example, in terms of reducing extra pounds - more effective development of aerobic fat capacity. In the case of running, however, the disadvantage is a relatively significant load on the musculoskeletal system. Depending on the running speed, the runner's foot must absorb 2 to 3 times his body weight with each step.

From the point of view of the main evaluation criteria, such as efficiency and health suitability, it seems to be a very suitable cross-country skiing, which allows both relatively high exercise intensity, ie high energy expenditure, and from the point of view of health prevention does not burden the supporting joints so much. However, cross-country skiing in winter conditions is tied to modified cross-country trails, which sometimes becomes a limiting factor.

Two-piece telescopic poles for Nordic Walking do not allow the correct execution of the bounce while running. In addition, the maximum length of these sticks is usually only 140 cm, which is insufficient for running with sticks due to other techniques. The handle is usually wider in the upper part, ie more massive, due to a different way of gripping, which would prevent easy holding of the multi-purpose stick and a slightly sliding movement of the hand when engaging the arm. The widening loop encloses the thumb due to a different technique of holding and bouncing, which would make it impossible to perform the engagement correctly when running with multi-purpose sticks; Velcro fastening is also quite impractical, which would be especially evident when running in winter. The steel tip would cause unpleasant noises when hitting a hard surface in the off-snow variant of running and would not dampen it in any way; in the snow variant of the run, it would not allow the sticks to bounce correctly.

- 1 CZ 306570 B6

Three-part telescopic trekking poles are also unsuitable for the reasons mentioned above, and in addition, two joints, i.e. two locking locks, would cause greater flexibility of the pole and a higher risk of its damage during running. The handle is usually shaped according to the grip of the fingers, which would cause abrasions and blisters when running. The loop is usually narrow and its length is adjusted using a buckle in the back of the hand, which could cause abrasions while running. The steel tip would cause unpleasant noises when hitting a hard surface during the off-snow variant of running and would not dampen it in any way. In the snow variant of the run, it would not allow the sticks to bounce correctly.

One-piece poles for cross-country skiing do not allow the combination of individual parts and running in off-snow conditions. It would also be necessary to produce a number of different sizes, respectively. stick lengths. The handle has a narrow profile and a smooth surface, allowing a slightly sliding movement of the hand when engaging the arm. Due to the different bounce technique, the loop is usually narrow - up to 2 cm wide, which would not allow the full force of the arm to be transferred to the stick when engaged with multi-purpose sticks. The curved grooving tip and the non-removable shaped snow plate allow the bounce of the poles to be carried out correctly during the snow version of the run.

The essence of the invention

Although some functional parts of individual types of known sticks are suitable, no sticks as a whole meet the specifics of running with sticks in the summer and winter variants. Some functional parts have to be made completely new.

The above-mentioned shortcomings are largely eliminated by a running sports aid, in the form of two sticks, one for each hand, according to this technical solution. Its essence is two telescopic poles consisting of two non-sprung parts with a maximum length of up to 160 cm and in a folded form with a length of 85 to 90 cm. The poles are equipped with a handle with a narrow profile and with a smooth surface and a strap wide at the handle 8 to 12 mm with an extension in the central part up to 35 mm. The pull-out part with a tip is replaceable. The stick is 250 to 400 mm smaller in unfolded form than the user's height.

The strap is preferably adjustable inside the handle.

The tip may be formed by a curved grooving tip and is preferably provided with a shaped snow plate, the tip and the plate being rotated in the direction of reflection.

In another embodiment, i.e. in the off-snow variant, the tip may be formed by a durable tip made of hardened rubber. Such a tip is preferably provided with a plastic ring to prevent excessive sticking of the stick into the soft substrate. In a preferred embodiment, the tip is provided with an anti-slip treatment.

A well-chosen length of sticks is very important. They should be five to ten centimeters shorter than the right-long cross-country ski poles, which, when measured in a room, reach just above the shoulders. The most accurate determination of the length of the sticks when measuring in the room is determined so that the stick should reach exactly to the hole between the sternum and the "nipple" of the neck. The angle at the elbow of the arm that holds the optimally long stick is approximately 50 °. Of course, after sticking the stick into the snow or soft terrain, it will increase depending on the height of the snow layer.

Stick grip plays an important role. All the fingers of the hand, naturally encircling the handle, participate in the grip. The grip must be neither too strong, ie convulsive, nor too loose, ie careless. A well-designed grip ensures that the force of the arm, when engaged, transmits the loop on the upper side of the hand in the correct way into a stick, which then naturally grounds it and thus allows the runner to bounce. The grip of the stick and the correct engagement of the arms require a narrow profile and a smooth surface of the handle, allowing a slightly sliding hand movement - similar to the classic technique when cross-country skiing.

-2EN 306570 B6

In contrast to the existing physical activities, running with sticks, resp. its summer and winter variants differ in the way some nodal movement phases are performed. These specifics are the reason for the use of special sticks, respectively. other methodologies of training techniques. The unequivocal advantage of running with sticks can be seen the lightening of the locomotor system during a relatively very intense run and maintaining its stability, especially in winter conditions on snow.

A runner with sticks gives more power, resp. has a significantly higher energy expenditure than during normal running. It breathes more intensively and engages the muscles of the chest area, shoulders and, of course, the arms more. When running with sticks, it not only runs, but also naturally strengthens. Unlike cross-country skiing, where the arms rest when driving downhill and the legs rest when bouncing off on the plane, the arms and legs do not rest when running with sticks. Therefore, when planning the length and difficulty of training, it is necessary to take into account the higher energy intensity of running with sticks.

Running with sticks requires a longer running step, ie not an ultra-long-lasting step, shortened, but a step with a completed bounce of the arms slightly behind the torso. Unlike cross-country skiing with the classic technique, the arm in the elbow does not extend completely, but max. Up to 120 °. This means that the stick no longer extends beyond the body after rebound - there is of course no ski slide that would allow this. To put it simply: the reflection of the poles when running with poles is shorter in time and space than the reflection of the poles when running on skis, resp. it can be compared to the middle phase of reflection with running sticks, ie. without moving the arms significantly in front of the torso and behind the torso.

On a straight and safe section, the stick is inserted roughly at the level of the heel of the opposite foot, ie the right stick is inserted into an imaginary line that is perpendicular to the direction of running and passes through the left heel, and vice versa. When running uphill, the torso is slightly tilted with an effort for a lighter and shorter stride with a reflection rather over the tip of the foot; however, this must be accompanied by a more vigorous grooving of the sticks, carried out higher - resp. identical to the step frequency. The most common beginner's mistakes are mainly equilateral reflection, ie simultaneous reflection with the left foot and left wand, respectively with the right foot and right wand.

Running with sticks allows you to run even in terrain conditions, in which it would not be possible without running sticks in any case. These are mainly narrow forest trails or other unpaved roads, very often trampled and covered with natural impurities, completely impossible to ski. "Connoisseurs" may dare into deeper snow - about 25 to 30 cm. Maximum caution is necessary in difficult terrain, which applies to icy sections, dangerous potholes, when crossing ditches or streams, etc. In these cases, it is necessary to hold the sticks really firmly and use them only as a support, not for dynamic reflection.

In general, it can be argued that running with multi-purpose poles brings an increase in running intensity and safety in any of its variants and at any performance level of the runner. The intensity factor results from the higher energy expenditure of running with sticks. Especially in the winter season - but not only in it, it can become a great advantage to reduce the time needed to complete a training unit with the required energy intensity - the same amount of energy is expended in a shorter time. There is no dispute about the high price of time saved in today's busy time; in the case of athletes, it can certainly be best "invested" in rehabilitation and regeneration.

There are several aspects to the safety factor: running with sticks primarily prevents injuries such as slipping, overloading the supporting joints, etc. The sticks also serve as a defensive tool in the event of a possible - unfortunately very common - attack on a runner by a dog. It is not possible to underestimate their defensive significance in the case of women running alone.

In addition to active athletes, running with sticks can be widely used by those whose current physical performance is low for various reasons, and thus significantly contribute to its increase. These are mainly overweight individuals, beginning runners, recreational runners practice

-3 CZ 306570 B6 not only jogging, but also about athletes after injuries who get back to their original physical condition as part of convalescence.

As for the intended use of stick running for performance and elite sports, the range of real possibilities is really very extensive. In the first place, of course, it is directly about runners, which allows mainly high-quality winter training: general endurance, special endurance intervals to submaximal speed, strengthening - bouncing sticks, running with folded sticks without grooving, half-taps, warm-ups and running exercises, etc. non-snow variants can be considered the most effective running with poles in the field, ie cross and fartrack, which applies not only to "normal" runners, but also to cross-country skiers and their preparation on dry land.

Multi-purpose poles would undoubtedly be widely used by athletes of "non-running" industries for the above reasons of higher intensity and safety of training, but also for practical and financial reasons, such as the purchase of a whole set of sticks of one, ie universal, size for the whole club or sports club. for all of them, let's name at least football players, basketball players, handball players, or other athletes. There can be no question about the benefits of their eventual winter training with the proposed sticks; the basic arguments have already been made.

This is especially true given the fact that all these sectors hold winter camps for their athletes to gain physical fitness and the necessary endurance base; however, when cross-country skiing as a training method, an injury can easily occur, for example, due to a lack of technique. In this context, we can not forget the summer camps, often held by the sea. Running in the beach sand is very demanding in terms of coordination and can therefore overload the lower limbs, which would be successfully solved by running with multi-purpose poles.

Examples of embodiments of the invention

The exemplary sports aid for running in Fig. 5, in the form of two poles 1, one for each hand, is formed by telescopic poles 1 consisting of two non-sprung two parts 11, 12 with a maximum length of 250 to 400 mm less than the user's height, provided a handle 3 with a narrow profile and a smooth surface with a strip 4 wide at the handle 3 8 to 12 mm with an extension in the central part up to 35 mm, the extendable part 12 with the tip 5 being replaceable. The strap 4 is adjustable inside the handle 3. The tip 5 is formed by a curved grooving tip 5 and is provided with a shaped snow plate 6, the curved grooving tip 5 and the plate 6 being rotated in the direction of reflection.

In another embodiment of Fig. 6, the tip 5 is formed by a durable tip made of hardened rubber. The tip 5 is provided with a plastic ring 6 to prevent excessive sticking of the stick 1 into the soft substrate.

-4GB 306570 B6

In yet another embodiment in Fig. 7, the foot of the tip 5 is provided with an anti-slip treatment.

The double-sectioned telescopic poles 1 allow running on a snow layer, running in the field and running on the road on the basis of a combination of a base part and two interchangeable extension parts 11 and 12.

The poles 1 are made without suspension, which allows a sharper reflection with the arms while running, for example compared to Nordic Walking, when using the suspension would cause excessive resonance of the pole 1. The impact of the pole 1 sufficiently dampens either snow or soft terrain or road rubber foot.

Sticks 1 are aluminum or carbon. Minimum weight is not a priority, it is the safety and stability of the runner. The total maximum length is up to approximately 160 cm - in comparison with Nordic Walking and trekking poles, whose length usually reaches a maximum of 140 cm. The reason is a different way of holding the stick 1 and a different design of the rebound than when walking with sticks 1. In a shortened, ie folded form, the length of the stick 1 reaches approx. 85 to 90 cm.

The narrow profile and smooth surface of the handle 3 allows a slightly sliding hand movement when performing the rebound. The material of the handle 3 takes into account the year-round use, ie use with or without gloves, depending on the temperature. The most suitable is plastic, or a combination of plastic with cork or rubber.

The loop is formed by a narrow strap 4, adjustable inside the handle 3. The strap 4 is threaded over the back of the hand between the thumb and fingertips of the hand. In the length of 5 to 6 cm, it widens to a width of about 3 cm. This ensures maximum efficiency in transferring arm force to the stick 1 during engagement. Furthermore, this guarantees maximum practicality, as the setting of the loop does not change further for the runner in question. Putting on a loop - it is much more common when running - is therefore quick and easy.

Depending on the type of surface for running, one of the two replaceable lower extendable parts 12 - snow Fig. 5, or the non-snow part Fig. 6 and 7 - is inserted and fixed in the basic, i.e. upper part 11 of the stick 1 with the handle 3.

The extendable snow section 12 corresponds to the design of a racing cross-country club, has a shaped snow plate 6 and a curved grooving tip 5. In order to perform the reflection correctly, after securing the extended part in the connecting member, ie after locking the stick 1, the tip 5 and the plate 6 direction of reflection, ie. in the axis of the stick 1. It can be used when running on a continuous snow base with a minimum snow layer height of 10 cm.

The retractable off-snow section 12 makes it possible to combine running in nature and running on the road. When running in the field, a durable tip made of hardened rubber is used, which - in addition to a slight damping of the impact force - primarily eliminates unpleasant sounds, which would make a metal finish when hitting a hard surface. An easy-to-install plastic ring prevents the stick 1 from sinking excessively into a soft surface. It can be used on field roads, forest roads, meadows, field edges, sand, discontinuous snow base with a snow layer height of less than 10 cm, etc.

An easy-to-install rubber foot with a non-slip finish is used for running on asphalt. Compared to the heel used in the Nordic Walking stick, it is wider and differently shaped, which absorbs the impact of the stick and at the same time allows the correct execution of the bounce. The optimal function of this foot is conditioned by its correct and constant position, ie it is prevented, for example by a fuse, from turning it in another direction. The foot of Nordic Walking poles is usually only a snap-on stick and would therefore easily turn when bouncing. It can be used on hard surfaces such as roads, asphalt, concrete, etc.

For safety reasons, above all, he never brakes with his wands in front of his body when running down a steeper hill. It brakes the legs and the sticks are naturally inserted at a sufficient distance next to them, which mainly fulfills the stabilizing function. Unlike normal running without wands, running with sticks does not wipe away tears, do not snort, do not adjust glasses or headband, etc. It is certainly better to stop for the above reasons than to injure yourself unpleasantly with a wand.

-5GB 306570 B6

Clothes suitable for running with sticks are not significantly different from clothes for normal running. In winter, there should be several thin layers of functional materials that allow comfortable arm movement, similar to the overalls used by cross-country skiers. Due to the more intense involvement of the arms and upper body, the runner will probably need a layer less than during normal running. In this case, finger gloves are inevitable, as the fingers of the hands holding the chopsticks cannot be warmed up by exercising in the same way as during normal running. In summer conditions, it could be cycling or other similar gloves, allowing the correct grip and grip even with sweaty hands.

In order for running with sticks to be as effective as possible, it requires - adequately running without sticks - a correctly chosen type of running shoes. In the case of running in the field and on snow, these are the so-called cross country shoes, ie running shoes with an otherwise structured sole, ie a deeper pattern, and other materials used are mainly goretex. In the case of running on asphalt or other hard and smooth surfaces, road models of running shoes with sophisticated cushioning elements are suitable.

Industrial applicability

According to this technical solution, the sports aid for running, in the form of two sticks, one for each hand, will find application mainly in recreational sports, elite sports and in healthcare, especially in rehabilitation.
