Objective: To examine the activity profiles of international goalball players and individual player profiles using wearable devices. Materials: All participants were Japanese national goalball players. Nine players were male (age: 24.7±5.9 years, height: 169.1±0.06 cm, weight: 73.1±10.0 kg) and 5 were female (age: 20.8 ±7.1 years, height: 158.2±0.06 cm, weight: 55.6±7.2 kg). Methods: Measured items were PlayerLoad^TM, acceleration, deceleration, change of direction, and heart rate responses. Inertial measurement units (IMU) and heart rate sensors were embedded in the wearable device used by participants. Each player’s highest PlayerLoad^TM value in a 10-sequence interval was referred to as the “peak value”, and the average 10-sequence interval value after the peak was expressed as “post value”. Percentage of HRmax (%HRmax) observed in one playing time was also assessed. Results: In male players, an approximately 50% decline in the mean PlayerLoad^TM value was observed (from peak to post). The same tendency was observed in the female players, although the amount of decline was not that high. In male players, 80%-90% HRmax was observed in approximately 60% of a game, whereas that of female players was 30%. Furthermore, in female players, 70%-80% HRmax was observed in approximately 50% of a game, whereas that of male players was 30%. Conclusions: The results provide scientific evidence for constructing a useful measurement tool when planning trainings for goalball players to improve their competitiveness.
