    Comparación de la densidad mineral ósea en futbolistas y árbitros de nivel profesional
    (Universidad de Murcia. Servicio de publicaciones, 2021) López García, Ricardo; Lagunes Carrasco, José Omar; Carranza García, Luis Enrique; Navarro Orocio, Ricardo
    El objetivo de este estudio fue comparar la densidad mineral ósea (DMO) de los futbolistas y árbitros de nivel profesional. Se realizaron mediciones de la densidad mineral del hueso con el equipo de absorciometría dual de rayos X (DEX A) en el cual se evaluaron las regiones de la columna, cadera, costillas, brazos, piernas y cuerpo completo a 27 futbolistas (19.81 ± 1.14 años de edad) y 22 árbitros (24.95 ± 3.54 años de edad) de la segunda división de la liga profesional de fútbol MX de México. Se utilizo el programa estadístico SPSS (21.0), utilizando la prueba para muestras independientes de la t de Student, considerando el valor de significancia de p ≤ .05. Los futbolistas lograron una mayor DMO que los árbitros en la mayoría de las regiones del cuerpo, encontrándose solamente diferencia significativa en las piernas y en la cadera (p ≤ .05). La alta mineralización de las piernas de los futbolistas se debe al alto contacto de repetidas ocasiones con el balón de juego, aunque también se obtuvo un alta DMO en los árbitros que en otros deportes de otros estudios. Concluyendo así que la práctica del arbitraje en el fútbol es positivo para el fortalecimiento del hueso. Sin embargo hacen falta realizar más estudios sobre la DMO en árbitros, réferi y jueces en el fútbol y en otras disciplinas.

    The effect of dietary estrogens and acupuncture combined with exercise or exercise alone on bone mineral density in adolescent female athletes suffering from the female athlete triad: A randomized clinical trial
    (Universidad de Murcia, Servicio de Publicaciones, 2023) Abd-Elfattah, Hanaa Mohsen; Reda Sakr, Hend; Morsi Galal, Dina Othman Shokri; Abdelkhalek, Mona; Hazim Abbassy, Amr; Emam Elnegamy, Tamer
    The aim of this study was to investigate the effect of dietary estrogens and acupuncture combined with exercise or exercise alone on bone mineral density in adolescent female athletes suffering from the female athlete triad. A single blind randomized controlled trial was carried out. A total of 44 girls (in adolescence age) diagnosed with low BMD (bone mineral density) resulting from female athlete triad participated in this study. They were divided into three equal groups (group A, B and C). Group A (n = 15) received estrogen from dietary origin in the form of soy milk or soybeans daily in the breakfast combined with weight bearing (WB) exercises. Group B (n = 15) received acupuncture therapy on the acupoints responsible for bone density according to Chinese meridians combined with WB exercises, while group C (n = 14) received WB exercises only. The program was given for 45-60 min/session, three sessions per week for 24 weeks. Z score by Dual-energy X-ray absorptiometry (DEXA) for bone mineral density (BMD) assessment and estradiol 2 (E2) for measuring serum estrogen in blood were measured before treatment and after 24 weeks of treatment. The study groups were comparable on all outcome measures. Within-group comparison showed statistically significant improvements in all measured variables (p < 0.05). Further, between-groups comparison revealed statistically significantly higher improvements in the measured variables, in favor of group B (p < 0.05). The acupuncture sessions combined with WB exercises may be effective in improving bone mineral density in female athlete triad, rather than diet modification by adding soy phytoestrogen in meals beside exercise or exercise alone.

    Time-restricted eating and bone health: a systematic review with meta-analysis
    (MDPI, 2024-03-18) Fernández Rodríguez, Rubén; Garrido Miguel, Miriam; Bizzozero Peroni, Bruno; Díaz Goñi, Valentina; Rodríguez Gutiérrez, Eva; Guzmán Pavón, María José; Meseguer Henarejos, Ana Belén; Torres Costoso, Ana; Fisioterapia
    Time-restricted eating (TRE) has emerged as a dietary strategy that restricts food consumption to a specific time window and is commonly applied to facilitate weight loss. The benefits of TRE on adipose tissue have been evidenced in human trials and animal models; however, its impact on bone tissue remains unclear. To systematically synthesize and examine the evidence on the impact of TRE on bone health (bone mineral content (BMC), bone mineral density (BMD), and bone turnover factors), PubMed, Scopus, Cochrane CENTRAL, andWeb of Science databases were systematically explored from inception to 1 October 2023 searching for randomized controlled trials (RCTs) aimed at determining the effects of TRE on bone health in adults (≥18 years). The Cochrane Handbook and the PRISMA recommendations were followed. A total of seven RCTs involving 313 participants (19 to 68 years) were included, with an average length of 10.5 weeks (range: 4 to 24 weeks). Despite the significant weight loss reported in five out of seven studies when compared to the control, our meta-analysis showed no significant difference in BMD (g/cm2) between groups (MD = −0.009, 95% CI: −0.026 to 0.009, p = 0.328; I2 = 0%). BMC and bone turnover markers between TRE interventions and control conditions were not meta-analyzed because of scarcity of studies (less than five). Despite its short-term benefits on cardiometabolic health, TRE did not show detrimental effects on bone health outcomes compared to those in the control group. Nevertheless, caution should be taken when interpreting our results due to the scarcity of RCTs adequately powered to assess changes in bone outcomes.
