Two Wearable Sensor Datasets recording the Countermovement Jump

These datasets come from two independent studies using wearable inertial sensors to estimate countermovement jump performance. The participants were healthy sports science students, free of injury, all of whom had given their prior written consent. Ethical approval was given by the governing institutions’ ethics committees, which included further analysis of the data. Smartphone Dataset: 119 valid jumps Peak power 40.7 +/- 8.9 W/kg 22 males, 10 females (26.5 +/- 4.1 yrs; standing height 1.74 +/- 0.08 m; body mass 70.0 +/- 10.9 kg) Redmi 9T phone (Xiaomi Technology, Beijing, China) 128 Hz sampling frequency Accelerometer & gyroscope Handheld at sternum level Mascia, G.; De Lazzari, B.; Camomilla, V.
