At least a portion of the paddle is transparent or translucent to allow at least a portion of the hand to cast a shadow as light shines through the paddle. ## Claims ### Claim 1 A swim paddle system comprising: a paddle that is substantially planar and rigid having a first side for receiving a hand of a swimmer and a second side opposing the first side with a plurality of through holes extending through the paddle from the first side to the second side, the first side having a palm region for receiving a palm of the hand and a peripheral region for receiving a thumb, an index finger, a middle finger, a ring finger, a little finger, and a wrist of the hand, the peripheral region being a region with an edge that defines the outermost extent of the paddle; wherein at least a portion of the paddle is transparent to allow at least a portion of the hand to cast a shadow as light shines through the paddle; and wherein at least a portion of the edge of the peripheral region has greater opacity than the at least a portion of the paddle that is transparent, the at least a portion of the edge of the peripheral region being provided along the edge such that the shadow of the hand is framed by a shadow outline of the paddle as the light shines through the paddle. ### Claim 2 (depends on 1) The swim paddle system of claim 1, wherein an entirety of the edge of the peripheral region has greater opacity than the at least a portion of the paddle that is transparent. ### Claim 3 (depends on 1) The swim paddle system of claim 1, wherein the plurality of through holes includes two or more first holes each of whose extension through the paddle has a minimum cross-sectional area that is smaller than a minimum cross-sectional area of the extension through the paddle of one or more second holes of the plurality of through holes, the two or more first holes for receiving two ends of a flexible strap to fasten the paddle to the hand. ### Claim 4 (depends on 3) The swim paddle system of claim 3, wherein the extension through the paddle of each of the two or more first holes is a cylinder having a first diameter and the extension through the paddle of each of the one or more second holes is a cylinder having a second diameter greater than the first diameter. ### Claim 5 (depends on 1) The swim paddle system of claim 1, further comprising one or more flexible straps sized to fit through two or more of the plurality of through holes to fasten the paddle to the hand. ### Claim 6 (depends on 5) The swim paddle system of claim 5, wherein the one or more flexible straps are made of rubber. ### Claim 7 (depends on 6) The swim paddle system of claim 6, wherein the one or more flexible straps are hollow tubes. ### Claim 8 (depends on 1) The swim paddle system of claim 1, wherein the peripheral region includes a wrist sub-region, for receiving the wrist, in which an edge of the peripheral region is recessed to allow freedom of motion of the wrist. ### Claim 9 A swim paddle system comprising: a paddle that is substantially planar and rigid having a first side for receiving a hand of a swimmer and a second side opposing the first side with a plurality of through holes extending through the paddle from the first side to the second side, the first side having a palm region for receiving a palm of the hand and a peripheral region for receiving a thumb, an index finger, a middle finger, a ring finger, a little finger, and a wrist of the hand, the peripheral region being a region with an edge that defines the outermost extent of the paddle; wherein at least a portion of the paddle is translucent to allow at least a portion of the hand to cast a shadow as light shines through the paddle; and wherein at least a portion of the edge of the peripheral region has greater opacity than the at least a portion of the paddle that is translucent, the at least a portion of the edge of the peripheral region being provided along the edge such that the shadow of the hand is framed by a shadow outline of the paddle as the light shines through the paddle. ### Claim 10 (depends on 9) The swim paddle system of claim 9, wherein an entirety of the edge of the peripheral region has greater opacity than the at least a portion of the paddle that is translucent. ### Claim 11 (depends on 9) The swim paddle system of claim 9, wherein the plurality of through holes includes two or more first holes each of whose extension through the paddle has a minimum cross-sectional area that is smaller than a minimum cross-sectional area of the extension through the paddle of one or more second holes of the plurality of through holes, the two or more first holes for receiving two ends of a flexible strap to fasten the paddle to the hand. ### Claim 12 (depends on 11) The swim paddle system of claim 11, wherein the extension through the paddle of each of the two or more first holes is a cylinder having a first diameter and the extension through the paddle of each of the one or more second holes is a cylinder having a second diameter greater than the first diameter. ### Claim 13 (depends on 9) The swim paddle system of claim 9, further comprising one or more flexible straps sized to fit through two or more of the plurality of through holes to fasten the paddle to the hand. ### Claim 14 (depends on 13) The swim paddle system of claim 13, wherein the one or more flexible straps are made of rubber. ### Claim 15 (depends on 14) The swim paddle system of claim 14, wherein the one or more flexible straps are hollow tubes. ### Claim 16 (depends on 9) The swim paddle system of claim 9, wherein the peripheral region includes a wrist sub-region, for receiving the wrist, in which an edge of the peripheral region is recessed to allow freedom of motion of the wrist. ### Claim 17 A swim paddle system comprising: a paddle that is substantially planar and rigid having a first side for receiving a hand of a swimmer and a second side opposing the first side with a plurality of through holes extending through the paddle from the first side to the second side, the first side having a palm region for receiving a palm of the hand and a peripheral region for receiving a thumb, an index finger, a middle finger, a ring finger, a little finger, and a wrist of the hand, the peripheral region being a region with an edge that defines the outermost extent of the paddle; wherein at least a portion of the paddle is transparent or translucent to allow at least a portion of the hand to cast a shadow as light shines through the paddle; and wherein at least a portion of the edge of the peripheral region has greater opacity than the at least a portion of the paddle that is transparent or translucent, the at least a portion of the edge of the peripheral region being provided along the edge such that the shadow of the hand is framed by a shadow outline of the paddle as the light shines through the paddle. ### Claim 18 (depends on 17) The swim paddle system of claim 17, wherein an entirety of the edge of the peripheral region has greater opacity than the at least a portion of the paddle that is transparent or translucent.
