These results demonstrate an association between antigliadin antibodies serum levels and SCA2. However, more work has to be done to clarify the clinical consequences of such an association.
El trabajo tiene como objetivo central valorar la condición física en atletas con discapacidad intelectual del Programa de Olimpiadas Especiales en el Atletismo, a partir de indicadores antropométricos físicas-condicionales. Se realizó un estudio descriptivo, exploratorio, no experimental desarrollado bajo un paradigma cualitativo, donde participaron 10 atletas con discapacidad intelectual, integrantes del equipo de Atletismo del Programa de Olimpiadas Especiales en Villa Clara. Se emplearon los métodos el análisis de documentos, la encuesta, la entrevista, la medición, análisis estadístico. Además, se realizaron mediciones antropométricas en miembros superiores e inferiores como alcances, longitudes y circunferencias, así como, indicadores de capacidades físicas condicionales como flexibilidad, fuerza de brazos, abdomen y piernas; rapidez y resistencia. Se utilizó el criterio de inclusión. Los resultados arrojaron las principales características antropométricas físicas-condicionales que distinguen a los atletas, así como, su análisis en función de las potencialidades para el deporte, a partir del comportamiento de los valores medios de cada indicador. La confiabilidad y validez de los instrumentos, nos arrojaron un intervalo de confianza del (95%), con un valor significación es (p<0.05)
Background:
Weightlifting is a practice that exerts a high degree of pressure on the skeleton when supporting large loads of weight. The practice of exercise contributes by improving bone mineral density (BMD) and can prevent problems associated with low BMD.
Objective:
The objective of the present study was to determine BMD and measure bone turnover using blood markers in weightlifting athletes in response to exercise.
Methods:
The study included 16 athletes and 16 controls of both sexes in the range of 18 to 22 years old. BMD was determined at the femoral neck, hip, lumbar spine, and Total Mineral Density (TMD). The value of the total mineral density (TMDV) was obtained from the sum of the BMD of the evaluated regions. Bone formation and resorption in blood were evaluated by Alkaline Phosphatase (ALP) and Acid Phosphatase (ACP), respectively. In addition, the concentration of urea and Creatine Kinase (CK) were determined.
Results:
The mean BMD of the lumbar spine and TMDV was of 1.2 g/cm2 in female and male athletes. In young people who did not practice weightlifting, BMD in the lumbar spine (0.9 g/cm2 in both groups) and TMDV (1.05 g/cm2 in women and 1.11 g/cm2 in men) were significantly lower (p <0.05). The activity in bone formation and CK in male athletes was twice as high compared to the other groups. The blood urea concentration in athletes (32.7- 38.0 mg/dL) was significantly higher (p <0.05) compared to the control groups (19.3-18.8 mg/dL).
Conclusion:
The practice of weightlifting benefits bone mass gain in the lumbar spine. These findings suggest that exercises in which high weight loads are supported promote bone turnover and mineralization to prevent bone weakening.
The main objective of the article is to analyze the pedagogical intervention to improve didactics through science and innovation in the teaching-learning process of Sport Sciences and Physical Activity. The research presented is qualitative, the study is descriptive, based on a non-experimental design. The participating subjects were selected intentionally, confirmed by the 31 eighth semester students of the Bachelor's Degree in Physical Culture and Sports of the University of Sonora, 16 of them are related to the female gender (51.62%), the other students are male 15 (48.38%). Of the eight teachers, five are female (62.5%), while three are male (37.5%). The methods applied were observation, questionnaire, review of documents, inclusion criteria and statistical analysis verifying the levels of reliability and validity of the data, which gave us a confidence interval of (90%), the SPSS program version 23 to determine the statistics presented in the materials and methods to deepen the importance of the art of teaching and integrating science and innovation as part of the structural categories that make up the didactics as: content, objectives, methods, means and evaluation for the welfare of the quality of education.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
