The use of inertial measurement unit (IMU) has become popular in sports assessment. In the case of velocity-based training (VBT), there is a need to measure barbell velocity in each repetition. The use of IMUs may make the monitoring process easier; however, its validity and reliability should be established. Thus, this systematic review aimed to (1) identify and summarize studies that have examined the validity of wearable wireless IMUs for measuring barbell velocity and (2) identify and summarize studies that have examined the reliability of IMUs for measuring barbell velocity. A systematic review of Cochrane Library, EBSCO, PubMed, Scielo, Scopus, SPORTDiscus, and Web of Science databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From the 161 studies initially identified, 22 were fully reviewed, and their outcome measures were extracted and analyzed. Among the eight different IMU models, seven can be considered valid and reliable for measuring barbell velocity. The great majority of IMUs used for measuring barbell velocity in linear trajectories are valid and reliable, and thus can be used by coaches for external load monitoring.

“…During the current study, horizontal work was left out of consideration in all exercises assessed, account being taken only of the vertical component, in accordance with the methodology previously validated by Flores et al (2016). According to Garhammer (1993), the horizontal work produced during the second pull in snatch and clean by a lifter of a light weight division, like the participant studied, represents a small component, less than 5%, of the total work produced.…”

“…In accordance with Flores et al (2016), data analysis included only the vertical acceleration attained by the barbell that was lifted, and only up to the finish of pull phase for snatch and clean, and up to the highest point of the bar's path before the catch position for back jerk and jerk. It should be noted that the lifter's body weight was not included in the calculations, so that the power calculations recorded the work done against the bar by the lifter.…”

“…The reliability of the results offered by these tests with the current measuring protocol has previously been validated (Flores, Sedano, de Benito and Redondo, 2016). This device was chosen for its easy portability in the weights room and minimum disturbance to the flow of the lifting sessions without compromising the weightlifter's technique in data collection (Sato, Smith and Sands, 2009).…”

Findings from mechanical power data can make a significant difference in the performance of athletes in weightlifting if it is properly understood by coaches. The purpose of this study was to examine the powerload (P-L) curve in the snatch, clean, back jerk and jerk of an international-level Spanish weightlifter. Four testing sessions were conducted in the present work. Session 1: estimating snatch and clean 1RM (1 repetition maximum); Session 2: power assessment of the snatch and clean across a spectrum of loads (30% to 100%) of the predetermined 1RM; Session 3: estimating back jerk and jerk 1RM; Session 4: power assessment of the back jerk and jerk across a spectrum of loads (30% to 100%) of the predetermined 1RM. The highest peak power output (Pmax) was reached with loads of 90% of 1RM in each exercise tested, which demonstrated this percentage to be the optimal load (Pmax load) to train power development during weightlifting exercises.Key words: snatch; clean; back jerk; jerk power; optimal load. AbstractCorrespondence/correspondencia: Francisco Javier Sánchez de Frutos Servicio de Educación Física y Deportes. Universidad de Salamanca. España Email: javierflores@usal.es El entendimiento por parte de los entrenadores de los datos de potencia mecánica obtenidos en la halterofilia puede marcar notables diferencias en el rendimiento de los atletas. El propósito de este estudio fue examinar la curva de carga-potencia en los ejercicios de arrancada, cargada, envión por detrás y envión en un halterófilo español de nivel internacional. Cuatro sesiones de evaluación fueron llevadas a cabo en este estudio. En la sesión 1 se estimó el 1RM (1 repetición máxima) en la arrancada y la cargada. En la sesión 2 se realizó una evaluación de la potencia alcanzada en la arrancada y la cargada en un espectro de cargas desde el 30% al 100% del 1RM predeterminado anteriormente. En la sesión 3 se estimó el 1RM en el envión por detrás y el envión. En la sesión 4 se realizó una evaluación de la potencia alcanzada en el envión por detrás y el envión en un espectro de cargas desde el 30% al 100% del 1RM predeterminado anteriormente. El pico de potencia mecánica fue alcanzado con el 90% del 1RM en cada uno de los ejercicios, mostrando dicho porcentaje como la carga óptima para el desarrollo de la potencia en ejercicios de halterofilia.Palabras clave: arrancada; cargada, envión; envión por detrás; potencia; carga óptima.

Recent technological developments have led to the production of inexpensive, non-invasive, miniature magneto-inertial sensors, ideal for obtaining sport performance measures during training or competition. This systematic review evaluates current evidence and the future potential of their use in sport performance evaluation. Articles published in English (April 2017) were searched in Web-of-Science, Scopus, Pubmed, and Sport-Discus databases. A keyword search of titles, abstracts and keywords which included studies using accelerometers, gyroscopes and/or magnetometers to analyse sport motor-tasks performed by athletes (excluding risk of injury, physical activity, and energy expenditure) resulted in 2040 papers. Papers and reference list screening led to the selection of 286 studies and 23 reviews. Information on sport, motor-tasks, participants, device characteristics, sensor position and fixing, experimental setting and performance indicators was extracted. The selected papers dealt with motor capacity assessment (51 papers), technique analysis (163), activity classification (19), and physical demands assessment (61). Focus was placed mainly on elite and sub-elite athletes (59%) performing their sport in-field during training (62%) and competition (7%). Measuring movement outdoors created opportunities in winter sports (8%), water sports (16%), team sports (25%), and other outdoor activities (27%). Indications on the reliability of sensor-based performance indicators are provided, together with critical considerations and future trends.
