The measurement system (44) includes an accessory (10) for being installed on the punching bag (14). The accessory (10) has a number of sensors (16) for receiving strike data, and a communications facility (42) for use in transmitting strike information to a computing device (50); wherein the system (44) is adapted for utilising an intermediate computing device (46) between the computing device (50) and the communications facility (42). In the system (44) the intermediate computing device (46) configured for assisting with the transmission of the strike information to the computing device (50). ## Claims ### Claim 1 A strike measurement device, comprising: a body adapted to be wrapped around a boxing, kickboxing or martial arts punching bag, the body including a number of sensors configured to detect strikes and to output strike force data indicative of the strikes; and one or more gripping portions provided on a rear surface of the body for gripping the punching bag; wherein the body has a width such that a single device, when positioned on the punching bag, is of sufficient circumferential extent for measuring the performance of a selected one from the group comprising leg directed strikes, torso directed strikes and head directed strikes to a front surface of the body; wherein the device has a height equal to less than a third of a height of the punching bag such that a plurality of the devices is required to be positioned on the punching bag to concurrently measure the performance of leg, torso, and head directed strikes to the front surface of the body; and wherein the body is: i) positionable at a lower position on the punching bag and configured to measure and categorise, left, right and central leg strikes; ii) positionable at a middle position on the punching bag and configured to measure and categorise left, right and central torso strikes; or iii) positionable at an upper position on the punching bag and configured to measure and categorise left, right and central head strikes. ### Claim 2 (depends on 1) A device as claimed in claim 1, wherein at least three of the devices are required to be positioned on the punching bag to concurrently measure the performance of leg, torso and head directed strikes to the front surface of the body. ### Claim 3 (depends on 2) A device as claimed in claim 2, including a computing device to concurrently measure strike information from the at least three devices. ### Claim 4 (depends on 1) A device as claimed in claim 1, including three groupings of sensors to respectively measure left, central and right strikes. ### Claim 5 (depends on 1) A device as claimed in claim 1, including at least two spaced apart fastening portions of length at least one quarter of the circumference of the punching bag. ### Claim 6 (depends on 5) A device as claimed in claim 5, wherein the fastening portions comprise Velcro strips. ### Claim 7 (depends on 1) A device as claimed in claim 1, wherein a user can assess his or her performance in overall power, speed, and accuracy of strikes. ### Claim 8 (depends on 1) A device as claimed in claim 1, wherein the gripping portions comprise strips of a rubber material. ### Claim 9 (depends on 1) A device as claimed in claim 1, including at least two spaced apart fastening portions, wherein the gripping portions are positioned underneath the at least two spaced apart fastening portions. ### Claim 10 A marital arts strike measurement system, comprising: a strike measurement device, comprising: a body adapted to be wrapped around a boxing, kickboxing or martial arts punching bag, the body including a number of sensors configured to detect strikes and to output strike force data indicative of the strikes; and one or more gripping portions provided on a rear surface of the body for gripping the punching bag; wherein the body has a width such that a single device, when positioned on the punching bag, is of sufficient circumferential extent for measuring the performance of a selected one from the group comprising leg directed strikes, torso directed strikes and head directed strikes to a front surface of the body; wherein the strike measurement device has a height equal to less than a third of a height of the punching bag such that a plurality of the devices is required to be positioned on the punching bag to concurrently measure the performance of leg, torso, and head directed strikes to the front surface of the body; and a communications facility for use in receiving the strike force data from the sensors and transmitting strike information to a computing device; wherein the system is adapted for utilising an intermediate computing device between the computing device and the communications facility, the intermediate computing device for assisting with the transmission of the strike information to the computing device. ### Claim 11 (depends on 10) A strike measurement system as claimed in claim 10, wherein the system is adapted for utilising the intermediate computing device between the computing device and the communications facility for assisting with the transmission of the strike information to the computing device on a substantially real-time basis. ### Claim 12 (depends on 11) A strike measurement system as claimed in claim 11, including an application for providing computer instructions for causing the computing device to query the intermediate computing device on a substantially real-time basis. ### Claim 13 (depends on 12) A strike measurement system as claimed in claim 12, wherein computer instructions are provided for causing the computing device to query the intermediate computing device at regular intervals. ### Claim 14 (depends on 12) A strike measurement system as claimed in claim 12, wherein the intermediate computing device is a smart phone. ### Claim 15 (depends on 10) A strike measurement system as claimed in claim 10, wherein the intermediate computing device is adapted to communicate wirelessly with the communications facility and with the computing device. ### Claim 16 A strike measurement device, comprising: a body adapted to be wrapped around a boxing, kickboxing or martial arts punching bag, the body including a number of sensors configured to detect strikes and to output strike force data indicative of the strikes; and one or more gripping portions provided on a rear surface of the body for gripping the punching bag; wherein the body has a width such that a single device, when positioned on the punching bag, is of sufficient circumferential extent for measuring the performance of a selected one from the group comprising leg directed strikes, torso directed strikes and head directed strikes to a front surface of the body; and wherein the device has a height equal to less than a third of a height of the punching bag such that at least three of the devices are required to be positioned on the punching bag to concurrently measure the performance of leg, torso, and head directed strikes to the front surface of the body, and the device includes a computing device to concurrently measure strike information from the at least three devices.
