Effects of multimodal cognitive exercise program on cognitive function, bone density, blood lipid, fitness, and depression in old women with mild cognitive impairment.

The purpose of this study is to verify the effects of participation in 12-week multimodal cognitive exercise program on cognitive function, bone mineral density, blood lipids, senior functional fitness, and depression of the old women with mild cognitive impairment and osteopenia. As a result, the exercise group showed significant effects in cognitive function, depression, bone mineral density, blood lipid, lower extremity flexibility, upper extremity flexibility, dynamic balance, and body endurance. Such results prove that multimodal cognitive exercise program is an effective interventional exercise program for improving cognitive function in the old women with mild cognitive impairment.

Effects of accelerated rehabilitation exercise after mbo on ankle function and strength in ankle instability / Efectos del ejercicio de rehabilitación acelerada después de tbm sobre la función y la fuerza en la inestabilidad del tobillo / Efeitos do exercício de reabilitação acelerada depois de tbm sobre a função e a força na instabilidade do tornozelo

ABSTRACT Background: Taekwondo athletes with lateral chronic ankle instability (LCAI) may experience difficulties with proprioception and ankle muscle strength. After surgery, a conventional rehabilitation exercise program can be ineffective, as it may not restore proprioception or muscle strength and, thus, result in minimal improvement. Objective: This study aimed to assess the effects of an ARE program following MBO on the proprioception, isokinetic strength, and endurance of ankle. Methods: Thirty athletes diagnosed with LCAI underwent MBO. They were divided into the ARE group (n=15) and the control group (CON, n=15). The ARE group performed early ARE exercises six times per week for 4 weeks. The parameters applied to test ankle muscle strength were angular speed of 30°/sec and 180°/sec (inversion: Inv. and eversion: Eve., respectively). Proprioception was measured as being able to sense a joint position of 15° of Inv. and 5° of Eve. Results: Significant differences were observed between the ARE and CON groups in ankle strength 30°/sec (Inv.: p<0.001, Eve.: p<0.001), 180°/sec (Inv.: p<0.001, Eve.: p<0.001), and proprioception at 15° (Inv.: p<0.001) and 5° (Eve.: p<0.001). Conclusions: We recorded significant short-term effects from early ARE in Taekwondo athletes with LCAI after MBO. The results provide reference data for the sports rehabilitator or ATC in evaluating the rehabilitation phase and informing patients about expectations after MBO in terms of performance status and the timing of return to sports.

RESUMEN Introducción: Los atletas de Tae Kwon Do con inestabilidad lateral crónica del tobillo (ILCT) pueden presentar dificultades con la propiocepción y la fuerza muscular del tobillo. Después de la cirugía, un programa convencional de ejercicios de rehabilitación puede ser ineficaz porque la propiocepción o la fuerza muscular pueden no restablecerse y, por tanto, dar lugar a una mejora mínima. Objetivos: Este estudio tuvo como objetivo evaluar los efectos de un programa de ERA después de TBM sobre la propiocepción, la fuerza isocinética y la resistencia del tobillo. Métodos: Treinta atletas diagnosticados con ILCT fueron sometidos a TBM. Se dividieron en grupo ERA (n=15) y grupo de control CON (n = 15). El grupo de ERA realizó ejercicios ERA precoces seis veces por semana durante 4 semanas. Los parámetros aplicados para probar la fuerza muscular del tobillo fueron la velocidad angular de 30°/s y 180°/s (inversión: Inv y eversión: Eve, respectivamente). La propiocepción se midió por la capacidad de sentir la posición articular de 15° de Inv y 5° de Eve. Resultados: Se observaron diferencias significativas entre los grupos ERA y CON en la fuerza del tobillo a 30°/s (Inv: p < 0,001, Eve: p < 0,001), 180°/s (Inv: p < 0,001, Eve: p < 0,001), y la propiocepción a 15° (Inv: p < 0,001) y 5° (Eve: p < 0,001). Conclusiones: Registramos efectos significativos a corto plazo con ERA precoz en atletas de Tae Kwon Do con ILCT después de TBM. Los resultados proporcionan datos de referencia para el rehabilitador deportivo o ATC (Certified athletic trainer) a la hora de evaluar la fase de rehabilitación e informar a los pacientes sobre las expectativas después de la TBM en cuanto a las condiciones de desempeño y el momento de retorno al deporte.

The Role of Contact Care by Adult Children in Relieving Depression in Older Adult Individuals.

The purpose of this study is to investigate how contact care by adult children influences the effect of caring for grandchildren on depression in older adult individuals. Studies have shown that caring for grandchildren either increases or decreases the symptoms of depression in older adult individuals, while other studies have shown no effect. The reason for these inconsistent results is that the key control variable, contact care by adult children, has been omitted from these previous studies. An analysis of panel data consisting of observations from 162 older adult respondents in the Korean Longitudinal Study of Aging over the 2008-2016 period confirms that the positive effect of caring for grandchildren on depression in older adults increased as the number of adult children who visited their older adult parents after entrusting their children to them increased. As more of their adult children visited the older adult individuals, the latter were more likely to feel that caring for their grandchildren was healing rather than stressful.

Effect of sildenafil citrate on brain central fatigue after exhaustive swimming exercise in rats.

Sildenafil citrate, a potent and selective inhibitor of phosphodiesterase type-5, is used clinically to treat erectile dysfunction and pulmonary arterial hypertension. We investigated the effect of sildenafil citrate on brain central fatigue through serotonin (5-hydroxytryptamine, 5-HT) synthesis after exhaustive swimming exercise in rats. The rats in the sildenafil citrate-treated groups received sildenafil citrate orally once a day for 14 consecutive days at respective dosage. On the 14 days after starting experiment, each animal was submitted to swimming test with intensity equivalent to overload. The exhaustion was defined as a state in which coordinated movements did not return to the water surface for breathing within 10 sec. Immunohistochemistry for 5-HT, tryptophan hydroxylase (TPH), and western blot for serotonergic type 1A (5-HT1A) receptor and 5-HT transporter (5-HTT) were performed. Exhaustive swimming exercise increased 5-HT and TPH expressions in the dorsal raphe and sildenafil citrate suppressed 5-HT and TPH expressions in the exhaustive swimming exercise rats. Exhaustive swimming exercise increased 5-HT1A receptor and 5-HTT expressions in the dorsal raphe and sildenafil citrate suppressed 5-HT1A receptor and 5-HTT expressions in the exhaustive swimming exercise rats. The significant suppressing effect appeared in the 20-mg/kg sildenafil citrate. Sildenafil citrate might be proposed as a potential ergogenic aid through anticentral fatigue.
