ABSTRACT
In this study, the effect of 12-week basic swimming training of sports science students on some respiratory parameters was determined. In the 2nd, 3rd and 4th grades of Gümüşhane University School of Physical Education and Sports, 64 (111) male students who did not take swimming lessons and 47 who took swimming lessons participated voluntarily. The experimental group was given breath work for 12 weeks during the course content and for 10 minutes at the end. Measurements were taken from the students twice before and after the 12-week education. SPSS 25.0 program was used in the analysis of the data collected within the scope of the research. Independent comparison of age, height and body weight measurements of the athletes in the experimental and control groups. Samples T Test was used. In the comparison of time, group, group x time changes of FVC, MVV, VC and FEV1 measurements, Repeated Measures ANOVA analysis was used. Statistical significance level was taken as (p<0.05). As a result of the research, a significant result could not be reached in FVC and FEV1 values between Tests, Groups and Group x time intervals, whereas VC was only between tests. However, statistically significant differences were found between MVV and VC Tests, Groups and Group x Time values. In short, it has been shown that students who take swimming lessons have statistically higher lung volumes than students who do not take the lesson. However, swimming activity can be recommended to increase respiratory efficiency of university students. (AU)
En este estudio, se determinó el efecto del entrenamiento básico de natación de 12 semanas de estudiantes de ciencias del deporte sobre algunos parámetros respiratorios. En los grados segundo, tercero, cuarto de la Escuela de Educación Física y Deportes de la Universidad de Gümüşhane, 64 (111) estudiantes varones que no tomaron clases de natación y 47 que tomaron clases de natación participaron voluntariamente. Al grupo experimental se le dio trabajo de respiración durante 12 semanas durante el contenido del curso y durante 10 minutos al final de la lección. Se tomaron pruebas de los estudiantes dos veces antes y después de la educación de 12 semanas. Se utilizó el programa SPSS 25.0 (Samples-T test) en el análisis de los datos recolectados dentro del alcance de la investigación. Comparación independiente de las medidas de edad, altura y peso corporal de los atletas en los grupos experimental y de control. En la comparación de los cambios de tiempo, grupo, grupo x tiempo de las mediciones de FVC, MVV, VC y FEV1, se utilizó el análisis ANOVA de medidas repetidas. El nivel de significancia estadística se tomó como (p<0,05). Como resultado de la investigación, no se pudo alcanzar un resultado significativo en los valores de FVC y FEV1 entre Pruebas, Grupos y Grupo x intervalos de tiempo, mientras que la VC fue solo entre pruebas. Sin embargo, se encontraron diferencias estadísticamente significativas entre los valores de MVV y VC Tests, Groups y Group x Time. En resumen, se ha demostrado que los estudiantes que toman lecciones de natación tienen volúmenes pulmonares estadísticamente más altos que los estudiantes que no toman la lección. Sin embargo, se puede recomendar la actividad de natación para aumentar la eficiencia respiratoria de los estudiantes universitarios. (AU)

OBJECTIVE: To determine whether the baseline parameters of forced spirometry can influence the positivity of the bronchodilation test (BDT), and whether this could have an influence in future positivity criteria. MATERIAL AND METHODS: A descriptive, cross-sectional study was conducted in a Primary Care setting. It included all patients referred by their family doctor to perform a forced spirometry test due to smoking, respiratory symptoms, or follow-up of respiratory diseases, between the months of June 2015 and February 2017. All of them were subjected to a forced spirometry with a BDT. RESULTS: A total of 295 patients were included, with a mean age 53.4±15.5 years, and 62% were male.An obstructive pattern was obtained in 20% of the spirometries, with 67.5% presenting with a mild obstruction, 18% a moderate, 9.6% moderate to severe, and 4.8% very severe. The BDT was positive in 8.8% of the spirometries, with 11.2% only positive in volume, and 17.6% were only positive in percentage. It was observed that the patients with a BDT positive in percentage had a lower base forced expiry volume in the first second (1.66 L/sec vs. 2.74 L/sec; P<.001), and a lower forced vital capacity (2.85 l vs.3.73 l; P<.001). The patients with a positive BDT in volume had a lower forced expiry volume in the first second (2.59 l/sec vs. 2. 62 l/sec; P<.001), and a higher forced vital capacity (3.89 l vs. 3.58 l; P<.001). CONCLUSIONS: The baseline forced expiry volume in the first second and forced vital capacity have an influence in the positivity of the BDT. This circumstance should be assessed when establishing the positivity of the BDT.

Avaliar a eficácia da técnica de expansão pulmonar Breath Stacking (BS) na melhoria da função respiratória de mulheres obesas submetidas a cirurgia bariátrica. Método: estudo quase-experimental com 36 mulheres (IMC ≥ 35 kg/m2) distribuídas de forma equitativa por dois grupos, de controlo (GC = 44,83±9,15 idade) e intervenção (GI = 45,78±8,03 idade). Os dados foram recolhidos em duas avaliações. Na 1ª avaliação (pré-cirúrgica), foi avaliada em ambos os grupos a função respiratória através das medidas CVF, VEF1, PIm, PEm, SpO2 e FR. No grupo de intervenção foi aplicada a técnica de expansão pulmonar de BS numa única sessão diária (6 repetições com pausa inspiratória de 5s), nas 24 horas pré cirurgia e após as 24, 48 e 72 horas pós intervenção cirúrgica. Na 2ª avaliação (72 horas pós cirurgia), avaliada em ambos os grupos a função respiratória. Para a execução da técnica de BS foi utilizada máscara facial com oclusão do ramo expiratório. Para a avaliação da CVF e VEF1 foi utilizado espirómetro portátil. Para a avaliação da PIm e PEm foi utilizado manómetro manual. Recorreu-se à análise estatística descritiva (m±DP), inferencial e ao teste bilateral de Mann-Whitney para comparação de dois grupos independentes. Foi definido como nível de significância p < 0,05. Resultados: Verificou-se homogeneidade dos dois grupos em relação à idade e parâmetros respiratórios na 1ª avaliação. Na 2ª avaliação verificou-se redução em todos os parâmetros exceto na FR: CVF (GC = -20,99±8,14 ml vs GI = -13,60±11,12 ml); VEF1 (GC = -23,05±9,5 ml vs GI = -13,38±11,26 ml); PIm (GC = -22,96±13,92 cm/ H2O vs GI = -14,93±15,75 cm/ H2O); PEm (GC = -14,10±9,71 cm/ H2O vs GI = -10,32±16,75 cm/ H2O); SpO2 (GC = -0,62±0,62 % vs GI = -0,001±0,35 %); FR (CG = 12,29±6,84 cmin vs GI = 6,45±6,71 cmin). Conclusões: A técnica de expansão pulmonar Breath Stacking foi responsável pela melhoria dos parâmetros respiratórios na 2ª avaliação, obtendo-se ganhos de 7% na CVF (p < 0,0049), 10% na VEF1 (p < 0,021), 8% na PIm (p < 0,0183), 4% na PEm (p < 0,0410) e 6% na FR (p < 0,0135) do GI relativamente ao GC.
To evaluate the efficacy of the Breath Stacking (BS) pulmonary expansion technique in improving the respiratory function of obese women undergoing bariatric surgery. Method: a quasi-experimental study with 36 women (BMI ≥ 35kg/m2) distributed equally in two groups, control (CG = 44.83 ± 9.15 age) and intervention (IG = 45.78 ± 8.03 age). The data were collected in two evaluations. In the first evaluation (pre-surgical), the respiratory function was assessed through both FVC, FEV1, PIm, PEm, SpO2 and RR measurements in both groups. On the intervention group, the pulmonary expansion technique of BS was applied on a single daily session (6 repetitions with inspiratory pause of 5s), in the 24 hours before surgery and after 24, 48, and 72 hours post-surgical intervention. In the second evaluation (72 hours post-surgical), respiratory function was evaluated on both groups. To perform the BS technique, facial mask with occlusion of the expiratory branch was used. For the evaluation of FVC and FEV1 a portable spirometer was used. Manual manometer was used for the evaluation of PIm and PEm. The descriptive statistical analysis (m ± SD), inferential and the Mann-Whitney bilateral test were used to compare two independent groups. The significance level was set at p < 0.05. Results: There was homogeneity of the two groups in relation to age and respiratory parameters in the first evaluation. In the second evaluation, there was a reduction in all parameters except in RR: FVC (GC = -20.99 ± 8.14 ml vs GI = -13.60 ± 11.12 ml); FEV1 (GC = -23.05 ± 9.5 ml vs GI = -13.38 ± 11.26 ml); PIm (GC = -22.96 ± 13.92 cm/ H2O vs GI = -14.93 ± 15.75 cm/ H2O); PEm (GC = -14.10 ± 9.71 cm/ H2O vs GI = -10.32 ± 16.75 cm/ H2O); SpO2 (GC = -0.62 ± 0.62 % vs GI = -0.001 ± 0.35 %); RR (CG = 12.29 ± 6.84 cmin vs GI = 6.45 ± 6.71 cmin). Conclusions: The Breath Stacking pulmonary expansion technique was responsible for the improvement of respiratory parameters in the second evaluation, with gains of 7% in FVC (p < 0.0049), 10% in FEV1 (p < 0.021), 8% in PIm (p < 0.0183), 4% in PEm (p < 0.0410) and 6% in IG RR (p < 0.0135) in relation to CG.
