BLOOD FLOW RESTRICTION SPORTSWEAR GARMENT
A sportswear garment comprising means for adjustably compressing at least one major vein in a user's limb such that blood flow through the at least one major vein is restricted.
1 . A sportswear garment comprising an integrated adjustable compression member to compress at least one major vein in a user's limb such that blood flow through the at least one major vein is restricted while permitting blood flow through major arteries in the user's limb, wherein either:
i) the garment is a top or t-shirt and the compression member is located in a sleeve of the top or t-shirt such that, in use, the compression member is positioned over an upper part of the user's arm proximate to the user's armpit; or
ii) the garment is a pair of shorts or a pair of trousers and the compression member is located in the leg of the pair of shorts or pair of trousers such that, in use, the compression member is positioned over an upper part of the user's thigh proximate to the user's groin.
2 . The garment of claim 1 , wherein the compression member comprises an elastic strap configured to be adjustable between a first configuration in which the compression member does not compress the at least one major vein and a second configuration in which the elastic strap is under tension and compresses the at least one major vein.
3 . The garment of claim 2 , wherein the elastic strap has first and second ends, and wherein at least one of the first and second ends is moveable relative to the other of the first and second ends so as to adjust the elastic strap between the first and second configurations.
4 . The garment of claim 3 , wherein the first end of the elastic strap is fixedly secured to the garment and the second end of the elastic strap is configured to be releasably secured to the garment.
5 . The garment of claim 3 , wherein at least one of the first and second ends is connected to a rotary dial with a ratchet mechanism, and wherein rotation of the dial allows the elastic strap to be tensioned.
6 . The garment of claim 4 , wherein the second end of the elastic strap is releasably secured to the garment by a catch and eyelet type fastening.
7 . The garment of claim 4 , wherein the second end of the elastic strap is releasably secured to the garment by a hook and loop type fastening.
8 . The garment of claim 1 , further comprising a sleeve or housing in which the compression member is at least partially contained.
9 . The garment of claim 8 , wherein the elastic strap has first and second ends, wherein at least one of the first and second ends is moveable relative to the other of the first and second ends so as to adjust the elastic strap between the first and second configurations, and wherein the second end of the elastic strap at least partially protrudes from the sleeve or housing when the elastic strap is in the first configuration.
10 . The garment of claim 9 , wherein the second end of the elastic strap is releasably secured to the garment by a hook and loop type fastening, and wherein one part of the hook and loop fastening is disposed on an exterior surface of the sleeve or housing and a complementary part of the hook and loop fastening is disposed at or proximate to the second end of the elastic strap.
11 . The garment of claim 1 , further comprising indicia to indicate an amount of compression applied by the compression member to the at least one major vein.
12 . The garment of claim 2 , wherein an underside of the elastic strap is provided with a pad or protrusion configured to apply additional pressure on the user's limb at a position appropriate to restrict blood flow in at least one major vein but to allow blood flow in major arteries.
13 . The garment of claim 12 , wherein the pad or protrusion is substantially solid.
14 . The garment of claim 12 , wherein the pad or protrusion is cushioned.
15 . The garment of claim 12 , wherein a position of the pad or protrusion along the length of the elastic strap is adjustable.
16 . The garment of claim 13 , wherein a position of the pad or protrusion along the length of the elastic strap is adjustable.
17 . The garment of claim 14 , wherein a position of the pad or protrusion along the length of the elastic strap is adjustable.
18 . The garment of claim 1 , further comprising a sleeve or housing in which the compression member is at least partially contained.
19 . A sportswear garment comprising an integrated adjustable compression member to compress at least one major vein in a user's limb such that blood flow through the at least one major vein is restricted while permitting blood flow through major arteries in the user's limb, wherein the garment is a top or t-shirt and the compression member is located in a sleeve of the top or t-shirt such that, in use, the compression member is positioned over an upper part of the user's arm proximate to the user's armpit.
20 . A sportswear garment comprising an integrated adjustable compression member to compress at least one major vein in a user's limb such that blood flow through the at least one major vein is restricted while permitting blood flow through major arteries in the user's limb, wherein the garment is a pair of shorts or a pair of trousers and the compression member is located in the leg of the pair of shorts or pair of trousers such that, in use, the compression member is positioned over an upper part of the user's thigh proximate to the user's groin.
