    A study of the reproducibility and reliability of the musculo-articular stiffness of the ankle joint
    (Elsevier, 2018-03-14) París-García, Federico; Alberto Barroso; Federico Paris
    The objective of this work was to evaluate the reproducibility, reliability and usefulness of the musculo-articular stiffness (MAS) of the ankle joint, measuring it by the free vibration technique. Seventeen (nine males and eight females) healthy university students were included in the study. Force (f), MAS (k) and unitary MAS (ku) (defined as the ratio between the value of stiffness k obtained in the test (absolute terms) and the value of force (f)) were obtained. A test retest protocol was designed and performed on the same day to determine the short-term reproducibility of f, k and ku. Short-term reproducibility of k and ku on 1 day in absolute terms (< 7% Coefficient of Variation (CV)) and relative reproducibility (Intraclass Correlation Coefficient (ICC) and Pearson ≥0.97) for both feet were obtained. The reliability of k and ku in absolute terms (< 9% CV) and in relative terms (ICC and Pearson≥0.93) based on repeating the protocol for 1 week was analysed for both feet. To analyse the usefulness, the Effect Size (ES) ratio=“Trivial” for all variables (for 1 day and 1 week) and the Smallest Worthwhile Change (SWC) ratio (Typical Error (TE)

    Risk perception evaluation in parents and/or guardians of a group of beginner traceurs before and after parkour practice
    (Editura Universitatea din Pitesti, 2018-07-30) Muñoz Llerena, Antonio; Férnandez Gavira, Jesús; Martín Nicaise, David; París-García, Federico
    The aim of this study is to evaluate the risk perception of parents and/or guardians of a group of beginner traceurs before and after parkour practice. Although the existing information about it was limited and had numerous distortions, it was successfully executed. This research has been carried out from interviews applied to 15 parents/guardians before and after a program of parkour practice. To this end, the sessions were recorded and subsequently viewed with the parents, creating a discussion forum. From the first interviews, in which almost all the parents had had the view that it was a very dangerous activity until the last interview, most of the interviewees changed their opinion, thinking that the risk of parkour depended mostly on its use by the person.

    Sensing Technologies in the Evaluation of the Mechanical Properties of the Plantar Flexors by Using the Free Vibration Technique
    (INTECHOPEN LIMITED, 2018) París-García, Federico; Ruiz-Zafra, Angel; Noguera, Manuel; Barroso, Alberto
    The use of free vibration techniques to evaluate the responsiveness of a one-degree-of-freedom dynamic system linked to musculo-articular stiffness (MAS) of the plantar flexors has become an accepted procedure in scientific literature. However, the applicability and widespread use of this parameter have been limited thus far for different issues. On the one hand, the measurement of this parameter requires a noninvasive, nonstress laboratory test, which implies the use of appropriate in-lab infrastructure, ad hoc mechanical devices, and specific signal sensing units. On the other hand, it requires an efficient treatment and processing of the signal data obtained from laboratory tests through different signal filtering techniques and mathematical transformations. In the present manuscript, the fundamentals of the free vibration technique, the measurement device, the adjustment procedure, and finally the software based on java platform are presented in order to show the applicability of the MAS as parameter to evaluate the functional response of one subject based on his mechanical response of the lower part of the body once the whole procedure is addressed and controlled to ensure the reproducibility and the reliability of the test.

    FLEXOR: A support tool for efficient and seamless experiment data processing to evaluate musculo-articular stiffness
    (Elsevier, 2019-08-23) París-García, Federico; Ángel Ruiz-Zafra; Manuel Noguera; Alberto Barroso-Caro
    Background and objective: The evaluation of musculo-articular stiffness (MAS) is an increasingly de- manded procedure with applications in different fields, such as sports performance and lower limbs injury prevention. However, this task is non-automated, time-consuming and error-prone due to man- ual handling of data streams and files across several software applications. Despite the fact that process automation of validated procedures helps to prevent errors, there is still a lack of easy-to-use tools for analysis, management and visualization of MAS trials. Methods: In the present work a tool called FLEXOR has been developed which applies mathemat- ical methods and novel algorithms to automatically adjust curves of data streams for MAS analysis decreasing substantially time employed and errors. This tool permits to define different adjustment parameters, detect curve peaks and valleys, and display the results on the fly. FLEXOR has been implemented through a component-based software development (CBSD) process. All physiological fundamentals for the biomechanical measurement have been included in the tool developed. To de- scribe the integration of all required components a 4 + 1 view model architecture has been used. The installation guide, the FLEXOR software and some data samples can be found on its GitHub repository ( ). Results: A multiplatform software tool to simplify traditional complex and manual procedures for MAS analysis is obtained. The tool turns them into a simple all-in-one procedure, reducing processing times from hours to a few minutes. The methodology was tested on multiple datasets generated by previous tools in former procedures as well as on real-time trials in the laboratory, showing identical results. Conclusion: The results show that the developed tool can accomplish an unfilled essential task in the analysis, management and visualization of MAS measurement. The presented software tool empowers analysts to handle the different studies, investigate different parameters related to each experiment and even test with different output parameters in each experiment, enabling real-time trials and shared stud- ies between different analysts.

    Influence of Dance Programmes on Gait Parameters and Physical Parameters of the Lower Body in Older People: A Systematic Review
    (MDPI, 2022-06-29) París-García, Federico; Rodríguez, Bárbara
    Abstract: (1) Background: The regular practice of dancing benefits the physical condition, improving quality of life and minimising the adverse effects of ageing. Therefore, this review aims to evaluate the impact of dance programmes by quantifying different physical parameters of the lower body in older adults. (2) Methods: A systematic qualitative review in the English language (PubMed, Scopus, OvidSP, Cochrane and PEDro database) until mid-2020 considering the PRISMA guidelines and the PEDro quality criteria considering the following parameters of gait: stride length and width, speed. Physical parameters: flexion and dorsiflexion joint, muscle strength and range of motion were carried out. (3) Results: 9 studies with a population of 544 subjects from 5 continents and 6 types of dances were taken into account. The improvement of some parameters over others depended on the type of dance and the movements generated, having moderate positive effects on strength, agility, mobility and balance. (4) Conclusions: there is a general improvement in the functional capacity of the elderly through the practice of ballroom dancing, with specific improvement of each parameter depending on the type of dance.

    Training volume and amateur cyclists’ health: a six-month follow-up from coinciding with a highdemand cycling event
    (Routledge Taylor & Francis Group, 2021-06-05) Oviedo-Caro, Miguel Angel; Mayolas-Pi, Carmen; París-García, Federico; Murillo Fuentes, Alfonso; Reverter-Masia, Joaquín; Bueno-Antequera, Javier; Munguía Izquierdo, Diego; Legaz-Arrese, Alejandro
    This study aimed to analyse the longitudinal association of amateur cycling training volume with health by comparing the proximity of participation in a high-demand cycling event. Variations in cycling training volume, behavioural cardiometabolic risk factors, and physical and psychosocial health were examined. Cyclists decreased their training volume by approximately 40% and their total physical activity volumes by approximately 20%, while controls maintained (~5%). A time*group interaction was found for men’s physical conditioning, body mass index and anxiety and, independent of gender, for behavioural cardiometabolic risk factors. Variation in cycling training volume was positively correlated with variation in physical conditioning and total physical activity and negatively correlated with variation in body mass index. The high level of cycling training volume developed at the time coinciding with a high demand cycling event predisposes to better physical health and behavioural cardiometabolic risk factors, without negatively affect psychosocial health, compared with six month later.

    Exercise Addiction Stability and Health Effects. A 6-Month Follow-up Postcompetition Study in Amateur Endurance Cyclists
    (American Society of Addiction Medicine, 2022) Bueno-Antequera, Javier; Oviedo-Caro, Miguel Ángel; Legaz-Arrese, Alejandro; París-García, Federico; Guillén-Correas, Roberto; Munguía Izquierdo, Diego; Mayolas-Pi, Carmen
    Objective: To study the longitudinal stability of exercise addiction and its health effects in apparently healthy amateur endurance cyclists from pre- to 6-month post-competition. Methods: In total, 330 (30 women) adult cyclists were divided into 4 groups based on scores on the Exercise Addiction Inventory at both periods: nonrisk (n=262, 79.1%), transient (n=35, 10.6%), emerging (n=14, 4.2%) and persistent (n=20, 6.1%). Results: The prevalence of high-risk exercise addiction was reduced postcompetition (16.7% vs 10.3%, p=0.017). Of the cyclists with a high precompetition risk of exercise addiction, 63.6% (35/55) had a transient addiction associated with favorable effects on mental quality of life (effect size [ES]=0.52, 95% confidence interval: [0.20, 0.86]) and sleep quality (ES=0.50 [0.89, 0.12]) and avoided the worsening of depression symptom severity compared to the remaining groups (ES range=0.51–0.65). The 5.1% (14/275) of cyclists with a precompetition low risk of exercise addiction presented emerging exercise addiction that was associated with a worsened mental quality of life compared to the remaining groups (ES ranged 0.59–0.91), sleep quality compared to the nonrisk (ES=0.56 [0.02, 1.10]) and transient (ES=0.72 [1.36, 0.08]) groups and anxiety symptom severity compared to the persistent group (ES=0.51 [1.20, 0.19]). Conclusions: Exercise addiction had a marked transitory component at 6-month postcompetition with associated health benefits in amateur endurance cyclists.
