Background: Badminton is one of the most popular sports in the world, and it is also one of the key sports of development in Taiwan. In recent years, the definition of intensity during exercise has become a high attention. Accurate monitoring of intensity not only improves sport performance but also reduces the probability of sport injuries. There are many methods for calculating the intensity index by the accelerator, such as Player Load and MAD (Mean Amplitude Deviation). The relation between these indexes in specific exercises and the exercise intensity has been confirmed by several reports. However, the appropriate indexes and placed placements for badminton have not been systematically discussed. Purpose: To compare the difference between acceleration intensity indexes and placed placements. Methods: Fifteen subjects worn a chest strap heart rate (HR) monitor on the chest and placed an accelerometer on the left wrist, trunk and right foot, respectively. The heart rate and acceleration data were collected during badminton exercises (six-point footwork) under three exercise intensities. After filtering the acceleration by 10 Hz low-pass filter, the Player Load and the MAD were calculated. The correlation coefficient between the heart rate and the acceleration intensity indexes were analyzed. Results: Both indexes showed that the accelerometer on hand has the highest correlation with the heart rate, foot was second, and the final was trunk. Conclusion: The best acceleration placement for badminton are on hands, foot was second. In the future, it can be considered to develop the smart badminton wristband or shoes to provide players a measurement of the exercise intensity in badminton.
