The slow component of oxygen uptake and efficiency in resistance exercises: a comparison with endurance exercises

2024-02-19T03:00:53Z

The slow component of oxygen uptake and efficiency in resistance exercises: a comparison with endurance exercises Garnacho-Castaño, Manu; Albesa-Albiol, Lluís; Serra Paya, Noemi; Gomis, Manuel; Feliu-Ruano, Raquel; Guirao Cano, Lluis; Pleguezuelos, Eulogio; Maté-Muñoz, José Luis There is a lack of information regarding the slow component of oxygen uptake (VO2sc) and efficiency/economy in resistance exercises despite the crucial role played in endurance performance. This study aimed to compare the VO2sc, efficiency/economy, metabolic, cardiorespiratory responses, rating of perceived effort and mechanical fatigue between cycling and half-squat (HS) exercises during a constant-load test at lactate threshold (LT1) intensity. Twenty-one healthy men were randomly assigned in a crossover design to perform cycle-ergometer or HS tests. The order of the two cycle ergometer tests was an incremental test for determining load-intensity in watts (W) at LT1, followed by a constant-load test at the LT1 intensity. [...]

Application of capacitive-resistive electric transfer in physiotherapeutic clinical practice and sports

Application of capacitive-resistive electric transfer in physiotherapeutic clinical practice and sports DE SOUSA DE SOUSA, LUIS EDUARDO; TEBAR SANCHEZ, CRISTINA; Maté-Muñoz, José Luis; Hernández-Lougedo, Juan; Barba, Manuel; Lozano Estevan, Maria del Carmen; Garnacho-Castaño, Manu; García Fernández, Pablo Diathermy techniques embody an oscillating electrical current passaging through the body tissues generating therapeutic heat; use of this technique in the physiotherapy field has been introduced recently, and because there is scarce information, the following review is proposed, aiming to explore the available evidence on applying CRET in physiotherapy clinical practice and sports. A systematic search was led through a keyword search on PubMed, MedLine, DialNet, Scopus, PEDro, Web of Science and Clinicaltrials databases. Including randomised controlled trials and quasi-experimental studies, which applied radiofrequency diathermy in sports and physiotherapy fields, without any restrictions on dates, published in Spanish, English, Portuguese or Italian.

Effect of muscle action on the kinetic and kinematic behavior of the barbell during isoinertial strength assessment

Effect of muscle action on the kinetic and kinematic behavior of the barbell during isoinertial strength assessment Garnacho-Castaño, Manu; Hernández-Lougedo, Juan; García Fernández, Pablo; Maté-Muñoz, José Luis An isoinertial strength assessment was performed to examine the kinetic and kinematic behavior of the barbell during several muscle actions. Velocity–time characteristics, force–time relationship, one repetition maximum (1RM), power output, and acceleration were compared in eccentric–concentric (EC) versus concentric only (C) sequences of the bench press (BP) and military press (MP). In two separate sessions, 28 and 29 resistance-trained athletes executed EC or C sequences in random order of the BP and MP, respectively, in an incremental load test up to their 1RM. Higher values were recorded in BP-EC than in BP-C, MP-EC, or MP-C (p < 0.01) for peak acceleration, peak rate of force development, peak rate of velocity development, and power output. [...]

Effects of introducing rest intervals in functional fitness training Hernández-Lougedo, Juan; Cimadevilla-Pola, Eduardo; Fernández-Rodríguez, Tomás; Guodemar-Pérez, Jesús; Otero-Campos, Álvaro; Lozano-Estevan, María del Carmen; Cañuelo-Márquez, Ana María; de Jesús-Franco, Fernando; Garnacho-Castaño, Manu; García Fernández, Pablo; Maté-Muñoz, José Luis Background: Functional Fitness Training (FFT) is a new exercise modality prioritizing functional multi-joint movements executed at high intensity as a circuit. Objective: To examine the impacts of introducing rest intervals in a FFT workout compared to “rounds for time” (RFT) FFT. Materials and Methods: Participants were 25 resistance-trained adults who completed two FFT workouts 1 week apart. The study design was crossover such that in a given session half the participants completed the standard and the other half the adapted FFT (FFTadapted). The workouts consisted of the same exercises (circuit of four rounds of exercises), but one (FFTadapted) included preset rest intervals (three sets of 1 min after each completed round). [...]
