A comparison between nine laboratories performing triangle tests
2012
WOS: 000299451400001; International audience; Fifteen groups of participants in nine laboratories performed triangle tests with two pairs of soft drinks. Groups differed in practice level with triangle tests: eight groups of 60 consumers who were not used to triangle test, three groups of qualified assessors who have already performed a few triangle tests, and four groups of trained assessors with a more extensive practice of triangle tests; qualified and trained groups included 9 or 18 assessors. The soft drinks were made from syrups at two levels of dilution in order to achieve about 55% of correct responses to test for difference and about 40% of correct responses to test for similarity.…
Ensayo no aleatorizado de un programa de fisioterapia continuo frente a interválico para pacientes con sobrepeso y síndrome coronario agudo
2020
Resumen: Presentamos un ensayo no aleatorizado de un programa de fisioterapia continuo frente a interválico para pacientes con sobrepeso y síndrome coronario agudo. Objetivo: Detectar diferencias entre un programa de fisioterapia (PF) continuo (CONT) y uno interválico (INT) en pacientes con sobrepeso y síndrome coronario agudo, respecto a parámetros antropométricos, analíticos, frecuencia cardiaca de reposo, adherencia a la intervención, desgaste, seguridad y tolerancia. Diseño: Estudio multicéntrico cuasiexperimental con diseño pre-post, no aleatorizado con muestreo por conveniencia con 2 brazos de tratamiento. Emplazamiento: Centros de prevención cardiaca comunitaria (Departamentos de Sal…
Acute effects of dynamic stretching on mechanical properties result from both muscle-tendon stretching and muscle warm-up
2019
We investigated the acute effects of dynamic stretching on mechanical properties of plantar flexor muscles and tested the hypothesis that it would result from an interaction between muscle-tendon stretching and muscle warm-up. To test the stretching effect, dynamic stretching (DS) was compared to static stretching (SS). To test the warm-up effect, DS was compared to submaximal isometric muscle activity (SIMA) with similar contraction intensity. A control condition served as reference. These four conditioning activities were time matched (2×20s) and tested on separate days on 13 volunteers. Electrical neurostimulation was applied to investigate muscle mechanical properties (peak doublet torq…
Pre-exercise skin temperature evolution is not related with 100 m front crawl performance
2020
During the transition between warm-up and competition there is a change in core, muscle and (eventually) skin temperature that may affect swimming performance. We have aimed to assess skin temperature evolution during transition phases of different durations before a typical front crawl effort and to investigate its relationship with performance. Following a standardized warm-up, nine adolescent male swimmers performed three maximal randomized 100 m maximum front crawl trials after 10, 20 and 45 min transition phases. Skin temperature, performance (time, stroke frequency, length and index, and propelling efficiency), heart rate, lactate and perceived effort were assessed. Data showed a skin…
Comparison of the Prolonged Effects of Foam Rolling and Vibration Foam Rolling Interventions on Passive Properties of Knee Extensors
2022
Foam rolling (FR) and vibration foam rolling (VFR) interventions have received attention as pre-exercise warm-ups because they maintain performance and increase range of motion (ROM). However, the immediate and prolonged effects and the comparisons between FR and VFR interventions are unknown. Therefore, this study was designed to compare the effects of FR and VFR interventions on passive properties of knee extensors over time (up to 30 min after interventions). A crossover, random allocation design was used with 14 male college students (22.1 ± 1.0 years old) in the control, FR, and VFR conditions. The knee flexion ROM, pain pressure threshold (PPT), and tissue hardness were measured befor…
Monitoring training and recovery responses with heart rate measures during standardized warm-up in elite badminton players.
2020
\(\bf Purpose\) To investigate short-term training and recovery-related effects on heart rate during a standardized submaximal running test. \(\bf Methods\) Ten elite badminton players (7 females and 3 males) were monitored during a 12-week training period in preparation for the World Championships. Exercise heart rate (HRex) and perceived exertion were measured in response to a 5-min submaximal shuttle-run test during the morning session warm-up. This test was repeatedly performed on Mondays after 1–2 days of pronounced recovery (‘recovered’ state; reference condition) and on Fridays following 4 consecutive days of training (‘strained’ state). In addition, the serum concentration of creati…
Effects of a Physical Activity Intervention on Physical Fitness of schoolchildren: The Enriched Sport Activity Program
2020
Background: Physical fitness in youth is a predictor of health in adulthood. The main objective of the present study was to understand if an enriched sport activity program could increase physical fitness in a population of schoolchildren. Methods: In a sample of 672 children aged 10.0 ±
Post-warm-up muscle temperature maintenance: blood flow contribution and external heating optimisation
2015
Passive muscle heating has been shown to reduce the drop in post-warm-up muscle temperature (T m) by about 25 % over 30 min, with concomitant sprint/power performance improvements. We sought to determine the role of leg blood flow in this cooling and whether optimising the heating procedure would further benefit post-warm-up T m maintenance. Ten male cyclists completed 15-min sprint-based warm-up followed by 30 min recovery. Vastus lateralis T m (T mvl) was measured at deep-, mid- and superficial-depths before and after the warm-up, and after the recovery period (POST-REC). During the recovery period, participants wore water-perfused trousers heated to 43 °C (WPT43) with either whole leg he…

Effects of heavy barbell hip thrust vs back squat on subsequent sprint performance in rugby players
2020
The objective of this research was to compare the effect of Post-Activation Performance Enhancement (PAPE) exerted on the back squat (BS) versus the barbell hip thrust (HT) on the sprint performance (5- and 10-m). 17 male amateur rugby players participated in the study (age 22.14 ± 2.52 years; body mass 81.06 ± 9.6 kg; height 1.78 ± 0.05 m). All participants performed a dynamic maximum strength test (3RM) in BS and HT at maximum speed. Two randomized sessions were performed inducing PAPE using BS or HT trough three series with three repetitions at 85% 1RM eight minutes before the sprint tests. An ANOVA of repeated measurement, found no differences in the time for 5-m (F = 0.398, P = 0.537, …
