SUMMARY: The aim of this study is twofold: (1) to identify differences in certain anaerobic parameters (10m sprint, 30m sprint, anaerobic power, and Illinois agility tests) between professional and amateur soccer players, and (2) to determine whether there is a difference in the ACTN3 gene polymorphism between professional and amateur soccer players. Ultimately, the goal is to reveal which parameters contribute to the differentiation in these two aspects. A total of 133 volunteer soccer players, including 71 professionals and 62 amateurs, participated in the research. DNA extraction from buccal epithelial cells was performed using a commercial kit to determine the genetic background of the athletes, and Real-Time PCR was conducted for genotyping. Statistical analysis of the findings obtained from the test results was performed using the SPSS 23 (SPSS Inc., Chicago, IL, USA) package program. The homogeneity of variance of the data was assessed using the Levene Test, and normal distribution analyses were conducted using the Shapiro-Wilk Test. Chi-square and Mann-Whitney U tests were employed for parameter analysis. The significance level was set at p0.05). However, there is a statistically significant difference in anaerobic parameters (10m sprint, 30m sprint, and anaerobic power) except for the Illinois test (p<0.05). In conclusion, our study found that gene polymorphism is not a differentiating factor between professional and amateur soccer players, but speed (10m and 30m) and anaerobic power parameters are differentiating factors.
Los objetivos de este estudio fueron: 1º identificar diferencias en ciertos parámetros anaeróbicos (sprint de 10 m, sprint de 30 m, potencia anaeróbica y pruebas de agilidad de Illinois) entre jugadores de fútbol profesionales y amateurs, y 2º determinar si existe una diferencia en el polimorfismo del gen ACTN3 entre jugadores de fútbol profesionales y aficionados. En definitiva, el objetivo fue revelar qué parámetros contribuyen a la diferenciación en estos dos aspectos. En la investigación participaron un total de 133 jugadores de fútbol voluntarios, incluidos 71 profesionales y 62 aficionados. La extracción de ADN de las células epiteliales orales se realizó utilizando un kit comercial para determinar los antecedentes genéticos de los atletas y se realizó una PCR en tiempo real para el genotipado. El análisis estadístico de los hallazgos obtenidos a partir de los resultados de las pruebas se realizó utilizando el programa de paquete SPSS 23 (SPSS Inc., Chicago, IL, EE. UU.). La homogeneidad de la varianza de los datos se evaluó mediante la prueba de Levene y los análisis de distribución normal se realizaron mediante la prueba de Shapiro-Wilk. Para el análisis de parámetros se emplearon las pruebas de Chi-cuadrado y U de Mann-Whitney. El nivel de significancia se fijó en p0,05). Sin embargo, existe una diferencia estadísticamente significativa en los parámetros anaeróbicos (sprint de 10 m, sprint de 30 m y potencia anaeróbica) excepto para la prueba de Illinois (p<0,05). En conclusión, nuestro estudio encontró que el polimorfismo genético no es un fac- tor diferenciador entre jugadores de fútbol profesionales y amateurs, pero sí los parámetros de velocidad (10 m y 30 m) y potencia anaeróbica.

SUMMARY: The purpose of this study was to reveal the differences between ACTN3 genotype (RR, RX, XX) and aerobic performance [Yo-Yo IRT1 (m), VO2 max (ml/kg/min)] in professional and regional amateur league soccer players and to reveal which of these parameters was a distinctive factor in these athletes.71 professional soccer players (age: 23.66 ± 4.11 years; body height: 1.79 ± 6.99 m; body weight: 76.02 ± 6.76 kg; body fat: 11.59±3.11 %) and 62 regional amateur soccer players (age: 23.63 ±3.77 years; body height: 1.81 ± 5.77 m; body weight: 76.36 ± 7.53 kg; body fat: 15.60±4.65 %) volunteered for the study. After DNA extraction from buccal epithelial cells via a commercial kit was performed for the genetic background of the athletes, Real-Time PCR was carried out for genotyping. Furthermore, Yo-Yo IRT1 test was performed to determine the aerobic performance of the soccer players. SPSS 23 (SPSS Inc., Chicago, IL, USA) package program was used for the statistical analysis of the data obtained in the tests. Shapiro-Wilk test for normality and Levene's test for homogeneity of variance were performed. Chi-Square, Independent Sample T Test and One Way ANOVA test were used in the analysis of the parameters. Statistical significance was set as p0.05); however, there was a statistical significance in favor of professional soccer players in terms of aerobic parameters (p<0.05). Consequently, it can be said that aerobic performance is the distinguishing factor, not the ACTN3 gene, in soccer players.
El objetivo de este estudio fue revelar las diferencias entre el genotipo ACTN3 (RR, RX, XX) y el rendimiento aeróbico [Yo-Yo IRT1 (m), VO2 max (ml/kg/min)] en jugadores de fútbol de ligas profesionales y amateurs regionales y determinar cuál de estos parámetros es un factor distintivo en estos deportistas. 71 futbolistas profesionales (edad: 23,66 ±4,11 años; altura corporal: 1,79 ± 6,99 m; peso corporal: 76,02 ± 6,76 kg; grasa corporal: 11,59±3,11 %) y 62 jugadores de fútbol amateur regionales (edad: 23,63 ± 3,77 años; altura corporal: 1,81 ± 5,77 m; peso corporal: 76,36 ± 7,53 kg; grasa corporal: 15,60 ± 4,65 %) se ofrecieron como voluntarios para el estudio. Después de realizar la extracción de ADN de las células epiteliales orales mediante un kit comercial para obtener los antecedentes genéticos de los atletas, se llevó a cabo una PCR en tiempo real para el genotipado. Además, se realizó la prueba Yo-Yo IRT1 para determinar el rendimiento aeróbico de los futbolistas. Para el análisis estadístico de los datos obtenidos en las pruebas se utilizó el programa SPSS 23 (SPSS Inc., Chicago, IL, EE. UU.). Se realizó la prueba de normalidad de Shapiro- Wilk y la prueba de homogeneidad de la varianza de Levene. En el análisis de los parámetros se utilizaron Chi-cuadrado, prueba T para muestra independiente y prueba ANOVA unidireccional. La significancia estadística se estableció en p0,05); sin embargo, hubo significación estadística a favor de los futbolistas profesionales en cuanto a los parámetros aeróbicos (p<0,05). En consecuencia, se puede decir que el rendimiento aeróbico es el factor distintivo, no el gen ACTN3, en los jugadores de fútbol.

ABSTRACT Objective: To determine the impact of postpolio-syndrome on quality of life in polio survivors. Methods: Forty polio survivors were included in the study. Twenty-one patients fulfilling the Halstead's postpolio-syndrome criteria participated in postpolio-syndrome group. The remaining nineteen patients formed non-postpolio-syndrome group. Control group was composed of forty healthy subjects. Quality of life was evaluated by Nottingham Health Profile, depression by Beck Depression Scale and fatigue by Fatigue Symptom Inventory. Isometric muscle strength was measured by manual muscle testing. Results: Total manual muscle testing score was 26.19 ± 13.24 (median: 29) in postpolio-syndrome group and 30.08 ± 8.9 (median: 32) in non-postpolio-syndrome group. Total manual muscle testing scores of non-postpolio-syndrome group were significantly higher than that of postpolio-syndrome group. Patients with postpolio-syndrome reported significantly higher levels of fatigue and reduced quality of life in terms of physical mobility, pain and energy when compared with patients without postpolio-syndrome and control group. It was not reported a statistically significant difference in social and emotional functioning and sleep quality between postpolio-syndrome, non-postpolio-syndrome and control groups. Also it was not found any statistically significant difference in Beck Depression Scale scores among the groups. Conclusions: Postpolio-syndrome has a negative impact on quality of life in terms of functional status, severity of pain and energy. The identification, early recognition and rehabilitation of postpolio-syndrome patients may result in an improvement in their quality of life.
RESUMO Objetivo: Determinar o impacto da síndrome pós-pólio na qualidade de vida nos sobreviventes da pólio. Métodos: Quarenta sobreviventes da pólio foram incluídos no estudo. Participaram do grupo de síndrome pós-pólio 21 pacientes que atenderam aos critérios de síndrome pós-pólio de Halstead. Os 19 restantes formaram o grupo não síndrome pós-pólio. O grupo controle foi composto por 40 indivíduos saudáveis. A qualidade de vida foi avaliada pelo Nottingham Health Profile, a depressão pela Escala de Depressão de Beck e a fadiga pelo Inventário de Sintomas de Fadiga. A força muscular isométrica foi medida por teste muscular manual. Resultados: O escore total do teste muscular manual foi 26,19 ± 13,24 (mediana: 29) no grupo de síndrome pós-pólio e 30,08 ± 8,9 (mediana: 32) no grupo não síndrome pós-pólio. Escores totais de teste muscular manual de grupo não síndrome pós-pólio foram significativamente maiores do que os do grupo de síndrome pós-pólio. Os pacientes com síndrome pós-pólio relataram níveis significativamente maiores de fadiga e qualidade de vida reduzida em termos de mobilidade física, dor e energia quando comparados com pacientes sem síndrome pós-pólio e grupo controle. Não se relatou uma diferença estatisticamente significativa no funcionamento social e emocional e na qualidade do sono entre grupos de síndrome pós-pólio, não síndrome pós-pólio e controle. Além disso, não se encontrou diferença estatisticamente significativa nos escores da Escala de Depressão de Beck entre os grupos. Conclusões: A síndrome pós-pólio tem um impacto negativo na qualidade de vida em termos de estado funcional, gravidade da dor e energia. A identificação, o reconhecimento precoce e a reabilitação dos pacientes com síndrome pós-pólio podem resultar em uma melhoria da qualidade de vida.

Four different cryoprotective supplemented stock media were evaluated for maintaining better survival and recovery of H. pylori type strain NCTC 11637 at two different maintenance temperatures of -20°C and -80°C after one month preservation as frozen stocks. The spread plate colony count method was used to investigate the recovery rate of H. pylori from equally inoculated bacterial suspensions in differently prepared stock cultures. After the preservation of H. pylori for one month in different cryoprotectant-supplemented stock media, the recovery rates for -20°C obtained for stock cultures supplemented with dimethyl sulfoxide (DMSO), polyethylene glycol (PEG), glycerol and glycerol+sucrose, as well as controls with and without human serum alone were 7.13, 6.97, 7.93, 7.99, 6.95 and 0.0 log CFU/ml, respectively. Maintenance of bacteria at -80°C gave statistically higher recovery rates compared to preservation at -20°C with the values of 8.55, 8.24, 8.59, 8.66, 8.01 and 0.0 log CFU/ml for these above mentioned stock cultures. The stock cultures supplemented with glycerol+sucrose and glycerol showed the highest recovery rates, 7.99 and 7.93 for -20°C vs. 8.66 and 8.59 for -80°C respectively, which were statistically different from the others. Our study revealed that H. pylori type strain NCTC 11637 could be better preserved at -80°C than -20°C. The best stock media which supported viability or culturability of bacteria were brain heart infusion broth (BHI)+glycerol+human serum and BHI+glycerol+sucrose+human serum, where the latter yielded the higher recovery rate.
