Analysis of Grip Amplitude on Velocity in Paralympic Powerlifting

(1) Background: Paralympic Powerlifting (PP) is a Paralympic modality that is predominantly about developing maximal force, as there are athletes who lift three times their body weight. Our objective was to evaluate the averages of the velocity for 30% and 50% of 1 Maximum Repetition (1 RM) on different amplitudes of the footprint in PP athletes; (2) Methods: The intervention happened over two weeks, with the first being devoted to the familiarization and testing of 1 RM, while in the second week, through the use of a linear Encoder, tests of velocity average (VA), velocity average propulsive (VAP), and velocity peak (VP) were carried out with loads of 30% and 50% of a maximum repetition 1 RM for 1× of the biacromial distance (BAD) 1.3 × BAD, 1.5 × BAD; (3) Results: There was a significant difference in the average velocity of 1 × BAD (1.16 ± 0.14 m/s, 1.07–1.26 IC; η2p 0.20) when compared to 1.3 × BAD (1.00 ± 0.17 m/s, 0.90–1.09 IC; η2p 0.20) over 30% of 1 RM. For the other velocity variables for 30% and 50% of 1 RM with different grip amplitudes, there were no significant differences; (4) Conclusions: In PP, the 1 × BAD footprint contributes significantly to VA at 30% of 1 RM when compared to the 1.3 × BAD and 1.5 × BAD footprints. For loading at 50% of 1 RM the VA, VAP and VP decreased when compared to 30% of 1 RM, to the extent that the VAP and VP generated with the 1.3 × BAD and 1.5 × BAD footprints were higher than those with 1 × BAD, other than for VA 50% of 1 RM, where the 1 × BAD footprint was superior to the others

Evaluaci?n de un programa de ejercicio f?sico sobre los marcadores de sangre y la calidad del sue?o en mayores.

Objective: Analyze the effects of a physical exercise program on blood markers and sleep quality in the elderly. Method: A total of 112 elderly people with metabolic diseases controlled by hypocholesterolemic and hypoglycemic medications participated in the study. The participants were divided into two groups, an exercise group composed of 54 individuals with a mean age of 62 years and control group of 58 individuals with a mean age of 63 years. Results: Blood glucose, total cholesterol, and triglyceride levels showed a mean reduction of 27.47, 18.13, and 23.48 mg/dl, respectively, and an increase of 8.98 mg/dl in the high-density lipoprotein level was seen. A significant change was seen in the low-density lipoprotein, very-low-density lipoprotein, and calcium levels on comparing the exercise group post-test values with that of the control group pre-test. The Pittsburgh Sleep Quality Index score showed a significant reduction of 3.15 (p < 0.001, p2=0.78) on comparing the exercise group with ?p2=0.78) on comparing the exercise group with the control group. the control group. Conclusion: It can be concluded that the physical exercise program, consisting of supervised walking and gymnastics with localized quadriceps muscle strengthening exercises, performed for 16 weeks at a frequency of three times a week for 60 min, was effective in improving the low-density lipoprotein and very-low-density lipoprotein levels and sleep quality of the elderly.Objetivo: Analizar los efectos de un programa de ejercicio f?sico sobre los marcadores sangu?neos y la calidad del sue?o en ancianos. M?todo: Un total de 112 personas mayores con enfermedades metab?licas controladas por medicamentos hipocolesterol?micos e hipoglucemiantes participaron en el estudio. Los participantes se dividieron en dos grupos, un grupo de ejercicio compuesto por 54 individuos, con una edad media de 62 a?os y un grupo control de 58 individuos, con una edad media de 63 a?os. Resultados: Los niveles de glucosa en sangre, colesterol total y triglic?ridos mostraron una reducci?n media de 27.47, 18.13 y 23.48 mg/dl, respectivamente, y se observ? un aumento de 8.98 mg/dl en el nivel de lipoprote?nas de alta densidad. Se observ? un cambio significativo en los niveles de lipoprote?nas de baja densidad, lipoprote?nas de muy baja densidad y calcio al comparar los valores de grupo de ejercicio post-test con los del grupo control pre-test. La puntuaci?n del Pittsburgh Sleep Quality Index mostr? una reducci?n significativa de 3.15 (p <0.001, ?p2=0.78) on comparing the exercise group with the control group.p2=0.78) al comparar el grupo de ejercicio con el grupo control. Conclusiones: Se puede concluir que el programa de ejercicio f?sico supervisado, consistente en caminar y realizar ejercicios de fortalecimiento muscular de cu?driceps, durante 16 semanas con una frecuencia de tres veces por semana durante 60 minutos, fue eficaz para mejorar los niveles de lipoprote?nas de baja densidad, lipoprote?nas de muy baja densidad y la calidad del sue?o de las personas mayores

Evaluation of the special judo fitness test, heart rate and lactate before and after training with restricted vision.

Objetivo: Avaliar o Special jud? Fitness Test (SJFT), a frequ?ncia card?aca (FC) e os n?veis de lactato (Lac) no desempenho dos atletas com e sem restri??o da vis?o antes e ap?s do treinamento restritivo da vis?o. Metodologia: Atrav?s do SJFT as vari?veis do ?ndice do teste, assim como verifica??o do desempenho dos atletas no treino e pos treino observando a freq??ncia card?aca atrav?s de um monitor card?aco RS 400- Polar e o n?vel de lactato, em dois momentos imediatamente ap?s o teste e 15` minutos p?s-teste com o judoca em posi??o passiva (repouso). A amostra foi composta por 30 atletas de Jud? com faixa et?ria de idade entre 18 a 30 anos, com experi?ncia m?nima de um ano de pratica da modalidade, todos do sexo masculino, onde a escolha se deu pelo fato de serem as categorias de idade mais concorrida atualmente no cen?rio competitivo. Resultados: Houveram diferen?as significativas no SJFT entre os testes com e sem restri??o de vis?o, na FC ap?s o teste, na avalia??o da FC ap?s 1 minuto, no Lac ap?s o teste, na avalia??o do Lac ap?s 15 minutos entre os grupos com restri??o de vis?o em todos os momentos, tanto com e sem restri??o de vis?o. Conclus?o: Os atletas com restri??o de vis?o tendem a apresentar uma adapta??o importante que indicou a melhor no teste com restri??o deste sentido.Objective: To evaluate the Special Judo Fitness Test (SJFT), heart rate (HR) and lactate (Lac) levels in the performance of athletes with and without restriction of vision before and after restrictive vision training. Methodology: Through the SJFT the variables of the test index, as well as verification of the performance of the athletes in the training and post-training observing the heart rate through a heart monitor RS 400- Polar and the level of lactate, in two moments immediately after the test and 15 minutes post-test with the judo in a passive position (rest). The sample consisted of 30 Judo athletes with ages ranging from 18 to 30 years, with a minimum of one year of practice of the modality, all male, where the choice was due to the fact that the categories were age currently in the competitive landscape. Results: There were significant differences in SJFT between the tests with and without visual restriction, HR after the test, HR evaluation after 1 minute, Lac after the test, Lac evaluation after 15 minutes between the groups with restriction of vision at all times, both with and without restriction of vision. Conclusion: Athletes with restricted eyesight tend to have an important adjustment that indicated the best in the restricted test of this sense
