The aim of this study was to validate a wearable inertial measurement unit (IMU), containing
a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The
absolute vertical acceleration of the IMU positioned on the back of the participant at L5 level …

In recent years, the use of sensors on mobile devices is highly desirable. In particular, an
accelerometer can be used for numerous applications such as tracking object or monitoring
of the elderly. This paper presents an application tool based on an accelerometer, call …

Wearable devices enable the unobtrusive sensing of a wide range of human activities and
the development of innovative applications. While the consumer market is pushing them
particularly as activity or heart rate trackers, their adoption in healthcare is still restricted to …

Sports biomechanics describes human movement from a performance enhancement and an
injury reduction perspective. In this respect, the purpose of sports scientists is to support
coaches and physicians with reliable information about athletes' technique. The lack of …

Vertical jump height is widely used for assessing motor development, functional ability, and
motor capacity. Traditional methods for estimating vertical jump height rely on force plates or
optical marker-based motion capture systems limiting assessment to people with access to …

This paper describes the research and implementation and validation method of a
smartphone application that calculates a vertical jump flight time, using the data collected
from the accelerometry sensors in a smartphone. To validate the algorithm results, a …

The main goal of this paper consists on the adaption and validation of a method for the
measurement of the energy expenditure during physical activities. Sensors available in a
mobile device, eg, a smartphone, a smartwatch, or others, allow the capture of several …
