Ítem Indoor air quality in a training centre used for sports practice(2023) Mazoteras-Pardo, Victoria; Losa-Iglesias, Marta Elena; Casado-Hernandez, Israel; Calvo-Lobo, César; Morales-Ponce, Ángel; Soriano-Medrano, Alfredo; Coco-Villanueva, Sergio; Becerro-de-Bengoa-Vallejo, RicardoBackground: One of the measures for controlling the coronavirus disease 2019 (COVID-19) pandemic was the mass closure of gyms. This measure leads us to determine the differences between indoor and outdoor air quality. That is why the objective of this study was to analyse the indoor air quality of a sports centre catering to small groups and rehabilitation. Methods: The study was conducted in a single training centre, where 26 measurements were taken in two spaces (indoors and outdoors). The air quality index, temperature, relative humidity, total volatile compounds, carbon monoxide, ozone, formaldehyde, carbon dioxide, and particulate matter were measured indoors and outdoors using the same protocol and equipment. These measurements were taken twice, once in the morning and once in the afternoon, with all measurements made at the same time, 10 am and 6 pm, respectively. Additionally, four determinations of each variable were collected during each shift, and the number of people who had trained in the room aÍtem Orthopaedic Simulation of a Morton's Extension to Test the Effect on Plantar Pressures of Each Metatarsal Head in Patients without Deformity: A Pre-Post-Test Study(MDPI, 2023-09-28) Sánchez-Serena, Anna; Losa-Iglesias, Marta Elena; Becerro-de-Bengoa-Vallejo, Ricardo; Morales-Ponce, Ángel; Soriano-Medrano, Alfredo; Pérez Boal, Eduardo; Grande-Del-Arco, Jessica; Casado-Hernandez, Israel; Martínez-Jímenez, EvaBackground: the area beneath the metatarsal heads is a common location of foot pain, which is often associated with high plantar pressures. The aim of this study was to determine the effect of the application of a Morton's extension on the pressure in the metatarsal bones of the foot using a pressure platform. Methods: twenty-five subjects without musculoskeletal pathology were selected for this study, and an experiment was conducted with them as the subjects, before and after application of a Morton's extension. The foot regions were divided into the forefoot (transversely subdivided into six areas corresponding to the first, second, third, fourth, and fifth metatarsal heads, and the hallux), midfoot, and rearfoot, and then the maximum and average pressures exerted at each region were measured before and after placing a Morton's extension. Main findings: we found a pressure reduction, with a p-value less than (p < 0.05), in the head of the second and third metatarsals in statics and dynamics. Conclusions:Ítem The Effectiveness of Hard Insoles for Plantar Pressure in Cycling: A Crossover Study(2023) Casado-Hernandez, Israel; Becerro-de-Bengoa-Vallejo, Ricardo; Losa-Iglesias, Marta Elena; Soriano-Medrano, Alfredo; Lopez-Lopez, Daniel; Navarro-Flores, Emmanuel; Pérez Boal, Eduardo; Martínez-Jímenez, EvaBackground: Hard insoles have been proposed to decrease plantar pressure and prevent foot pain and paresthesia due to repetitive loading. The aim of this research was to analyze the effect of three different hard insoles in cycling on healthy subjects. Methods: A crossover randomized trial was carried out. The mean age of the subjects was 35 ± 3.19 years, and all of them were men. While the subjects were cycling on a stationary bicycle, their plantar pressure was recorded with nine in-shoe sensors placed in nine specific foot areas to test a standard ethylene-vinyl-acetate 52° Shore A hardness insole, a polypropylene 58° Shore D insole, and a polypropylene 580 Shore D insole with selective aluminum 60 HB Brinell hardness in the metatarsal head and hallux. Results: The maximum plantar pressure decreased significantly with the polypropylene insole containing selective aluminum in the metatarsal head and hallux areas. The maximum plantar data of the polypropylene aluminum insole in the M2 area (5.56 kgF/cm2),
