Slackline apparatus and training method
A portable human balance training device for improving the human proprioceptive system, athletic performance, athletic speed, athletic agility, athletic vertical leap, athletic eye/hand coordination, spatial awareness, left/right brain organization and increasing the muscular development of a user. The balancing device has an elongated suspended support structure spanning the length of the device. The balancing device also has an end support structure at each end for suspending and stabilizing the support structure. A flexible line is mounted to the end supports and spans the length of the support structure. The user places all or part of their body weight on the suspended support band and attempts to balance.
1. A training device comprising:
a central beam member, the central beam member having a first end and a second end;
a pair of arcuate outer beam members, one attached to the first end of the central beam member and the other attached to the second end of the central beam member to form an elongate bow-shaped beam assembly; and
a pair of end bracket assemblies supporting the elongate beam assembly therebetween; and
a flexible line extending between the pair of end bracket assemblies configured for a user to perform balance training thereon, wherein each of the end bracket assemblies comprise a plurality of mounting positions for carrying the flexible line such that a vertical distance, measured between the points of engagement of the flexible line to the mounting positions and the central beam member, is adjustable between a plurality of different height settings, each of the plurality of different height settings corresponding to a respective one of the plurality of mounting positions.
2. The training device of claim 1 , wherein a tension of the flexible line is adjustable.
3. The training device of claim 2 , wherein the plurality of mounting positions combined with the bow-shaped beam assembly allows for adjustment to the flexible line length and/or tension to provide sufficient slackness to the flexible line without the flexible line bottoming out on the beam due to a force being applied thereto by a user and causing the beam to flex away from the line.
4. The training device of claim 1 , further comprising a second pair of end bracket assemblies carrying a second flexible line.
5. The training device of claim 4 , wherein the second pair of end bracket assemblies are coupled to opposite ends of a second beam structure comprising a second central beam member and a second pair of outer beam members.
6. The training device of claim 1 , wherein a ratio of vertical spacing H between the central beam member and the point of attachment of the flexible line to the end bracket assemblies to horizontal length L of span of the flexible line (H/L) is between 0.05 to 0.09.
7. The training device of claim 6 , wherein the H/L ratio is between 0.06 to 0.08.
8. The training device of claim 6 , wherein the H/L ratio is approximately 0.07.
9. The training device of claim 1 , wherein the central beam member has a greater moment of inertia than the outer beam members.
10. The training device of claim 1 , wherein the flexible line spans a horizontal length of at least 9 feet.
11. The training device of claim 1 , wherein the vertical distance between the central beam member and the point of attachment of the flexible line to the mounting positions is at least 8 inches.
12. The training device of claim 1 , wherein ends of the outer beam members extend into an internal channel of the central beam member.
13. The training device of claim 1 , wherein the arcuate outer beam members generally extend oppositely and axially from the first and second ends of the central beam member.
14. The training device of claim 1 , wherein the elongate beam assembly is generally curved.
15. A training device comprising:
a pair of end supports, each end support comprising a base, an upright portion having a lower end attached to the base and an upper end extending away from the base, and an arm extending outwardly from the upright portion between the lower end and the upper end;
a flexible line extending between the upright portions of the end supports proximal their upper ends thereof wherein the flexible line is configured for a user to perform balance training thereon; and
a bow-shaped beam extending between the arms of the end supports,
wherein a plurality of corresponding mounting members are provided at different distances from the upper ends of the upright portions of each end support, and wherein the flexible line is selectively engageable with corresponding pairs of the plurality of corresponding mounting members to adjust a height of the flexible line.
16. The training device of claim 15 , wherein the beam is bow-shaped and curves away from the flexible line.
17. The training device of claim 16 , wherein the curvature of the bow-shaped beam defines a vertical distance between the beam and points of connection of the flexible line to the end supports of at least 8 inches.
18. The training device of claim 15 , wherein the beam comprises a central beam member and a pair of outer beam members.
19. The training device of claim 18 , wherein the central beam member has an internal channel extending at least partially therethrough, and wherein ends of the outer beam members extend into the internal channel of the central beam member.
20. The training device of claim 15 , further comprising a second pair of end supports carrying a second flexible line.
21. The training device of claim 20 , further comprising a second beam extending between the second pair of end supports.
22. The training device of claim 15 , wherein the flexible line spans a length of at least 10 feet.
23. The training device of claim 15 , wherein the tension of the flexible line is adjustable.
