Reliability and Accuracy of Linear Position Transducers During the Bench Press ...
Montoro-Bombú, Raynier; Costa, Armando; Sousa, Paulo Malico; Pinheiro, Valter; Forte, Pedro; Monteiro, Luis; Ribeiro, Alex S.; Rama, LuisSelecting the right linear position transducer (LPT) for velocity-based training monitoring sometimes presents uncertainties for coaches. Objectives: This study rigorously examined the test-retest reliability of three LPT–Cs using a simultaneous triangulation method of the same device during bench press (BP) and back squat (SQ) exercises performed on a Smith machine. Methods: Forty university students—13 female...
Validity and Reliability of a Load Cell Sensor-Based Device for Assessment of t...
Montoro-Bombú, Raynier; Gomes, Beatriz; Santos, Amândio; Rama, LuisIn recent years, there has been an exponential increase in the number of devices developed to measure or estimate physical exercise. However, before these devices can be used in a practical and research environment, it is necessary to determine their validity and reliability. The purpose of this study is to test the validity and reliability of a load cell sensor-based device (LC) for measuring the peak force (P...
The validity of the push band 2.0 on the reactive strength index assessment in ...
Montoro-Bombú, Raynier; Arencibia, Lázaro de la Paz; Buzzichelli, Carlo; Miranda-Oliveira, Paulo; Fernandes, Orlando; Santos, Amândio; Rama, LuisThis study aims to verify the validity of the Push Band 2.0 (PB2.0) device on the reactive strength index (RSI) measurement, using a force plate (FP) and an optical sensor device, OptoJump (OPT), as a reference. Twenty trained athletes performed 60 drop jump trials with a height box of 30 cm. A randomized repeated measures study was conducted during a single session using the PB2.0, the OPT, and the plate force...

No. of bitstreams: 0 Previous issue date: 2020-08-04; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); This study examined the effect of a competitive season on salivary responses [cortisol (sC), testosterone (sT), Testosterone/Cortisol ratio (sT/C), Immunoglobulin A (sIgA), sIgA secretion rate (srIgA), alpha-amylase (sAA)] and upper re...
Daily hematologic assessment during a 230-km multistage ultramarathon
Minuzzi, Luciele Guerra; Teixeira, Ana Maria; Carvalho, Humberto Moreira; Costa, Ricardo José da; Rama, LuisIntroduction: The popularity of ultra-endurance events is increasing worldwide. However, information about hematological parameters during repeated bouts of long-duration running, such as stages during a multi-stage ultramarathon (MSUM) is scarce. Objective: The purpose of the study was to monitor daily hematologic assessment in a 230-km multistage ultramarathon (MSUM) in hot environmental conditions. Methods: ...
Cardiac remodeling indicators in adolescent athletes
Castanheira, Joaquim; Valente-dos-Santos, João; Costa, Daniela C.; Martinho, Diogo; Fernandes, Jorge; Duarte, João; Sousa, Nuno; Vaz, Vasco; Rama, LuisObjective: The idea that different sports and physical training type results in different cardiac adaptations has been widely accepted. However, this remodelling process among different sport modalities is still not fully understood. Thus, the current study aims to investigate the heart morphology variation associated with a set of different modalities characterized by distinct models of preparation and differe...
