More minutes of physical activity (PA) accumulated during a day are associated with alower risk of diabetes mellitus type 2. However, it is less known if distinct dimensions of PA can produce a different protective effect in the prevention of prediabetes. The aim of this study was to analyze the impact of work and recreational PA on prediabetes among U.S. adults during the period 2015–2016 using the National Health and Nutrition Examination Survey (NHANES) database. Individuals (n = 4481) with hemoglobin A1c (HbA1c) test values of 5.7% to 6.4% were included. A logistic regression multivariate-adjusted analysis was conducted to estimate the association between the odds ratios (ORs) and 95% confidence intervals (CIs) of prediabetes, with work and recreational PA. The prevalence of prediabetes among U.S. adults was lower in physically active individuals both at work (~24%) and recreational (~21%) physical activities compared to individuals who were not physically active (27 to 30%). Individuals lacking practice of recreational PA had a high risk of prediabetes (OR = 1.26, 95% CI: 1.080 to 1.466). PA may be a protective factor for prediabetes conditions depending on gender, age, ethnic group, waist circumference, and thyroid disease.

Objective: To analyse the effect of the manual ischemic compression (IC) on the upper limb motor performance (MP) in patients with LTrPs. Materials and methods: A quasiexperimental study was performed in twenty subjects allocated to either patient’s group with LTrPs (PG, n=10) or healthy group with no symptoms (HG, n=10). Subjective pain and linear MP (movement time and Fitts' Law) were assessed before and after a linear tapping task. Data were analyzed with mixed factorial ANOVA for intergroup linear motor performance differences and dependent t-student test for intragroup pain differences. Results: PG had a linear MP lower than the HG before treatment (p < 0.05). After IC, the PG showed a significant decrease of pain (4.07 ± 1.91 p < 0.001). Furthermore, the movement time (15.70 ± 2.05 p < 0.001) and the Fitts' Law coefficient (0.80 ± 0.53 p < 0.001) were significantly reduced. However, one IC session did not allow the PG to get the same MP than the HG (p < 0.05). Conclusion: The results suggest the IC effectiveness on pain and MP impairment in subjects with LTrPs. However, the MP of these patients is only partially improved after the IC application.

BACKGROUND: Exaggerated cardiovascular response to a subsequent psychosocial challenge (cardiovascular reactivity) have an adverse effect on future cardiovascular risk status in younger populations. Several studies have shown that black individuals exhibited significantly greater blood pressure (BP) and heart rate (HR) responses to stressors than white individuals. The purpose of the study was to determine whether interval exercise reduces cardiovascular reactivity and recovery from stress in black adolescents. METHODS: In a counterbalanced order and one-week apart, black Cuban adolescents (n=25) completed an interval exercise program followed by the Trier Social Stress Test for Child (TSST-C) and no exercise followed by the TSST-C. The exercise consisted of a cycle ergometer fitness test (5-min, 50 rpm, 60% HR reserve), followed by 60-s rest, and another bout of exercise (6-min, 80 rpm, 30-s intervals) at the resistance that elicited the target HR reserve during the fitness test. Adolescents rested 2-min before completing another 6- and 4-min interval exercises. Following a 5-min post-intervention period, adolescents completed the TSST-C. BP, HR and heart rate variability (HRV) were measured before, during and after the exercise and TSST-C. RESULTS: Systolic blood pressure (SBP) remained unchanged following exercise. TSST-C-induced changes in BP, HR and HRV reactivity were not reduced for aerobic exercise. Recovery SBP and HR were reduced in the exercise condition (P<0.01, CI95% = -8.36, -2.51, and P<0.01, CI95% = -8.07, -4.31, respectively). CONCLUSIONS: Acute interval aerobic exercise appears to have a significant impact on cardiovascular recovery in black adolescents who have suffered stressful events.

Objective: the purpose of the present study was to analyze the concurrent validity and reliability of a force platform clinical COBS Feedback® for the estimation of the height of vertical jumps. Design: a cross-sectional correlational and comparative study. Setting: University Human Movement and Physiotherapy Laboratory. Participants: healthy university students (14 female and 13 male) aged between 18 and 25 years old (mean = 20.074 ±1.542). Main Outcome Measures: vertical jump heights, technical error and grade of agreement between methods of measurement. Results: after the 27 subjects performed a total of 135 vertical jumps on COBS Feedback®platform while simultaneously being recorded with a high-speed camera-based method, the intraclass correlation coefficient showed an almost perfect concordance between the two methods (ICC = 0.916, CI95%= 0.882 to 0.940, p<0.001). The technical error of the COBS Feedback® against HSC-Kinovea video analysis was at 0.310±0.223m, being higher in males than in females (t= -2.822, CI95%: -0.376 to -0.574, p=0.001). Conclusions: the COBS Feedback® method provided a valid measurement of the flight times for estimate the vertical jump height as a number of well-known tests and devices.

La mastitis puerperal no infecciosa es una inflamación de las glándulas mamarias que causa dolor, calor y enrojecimiento. Generalmente, el tratamiento conservador incluye la aplicación del masaje convencional (MC). Sin embargo, hay escasa evidencia que analice el efecto del drenaje linfático manual (DLM), siendo su aplicación eficaz en la remoción de líquidos. El objetivo de este estudio fue comparar el efecto del DLM vs MC. El estudio fue un ensayo clínico aleatorizado que incluyó 15 madres primigestas repartidas en un grupo control (GC) y dos grupos experimentales GDLM y GMC de 5 participantes cada uno. En todos los grupos se evalúo la cantidad de leche extraída, los perímetros mamarios (longitudinales y transversales) y el dolor, antes y después de 6 sesiones de intervención. Se realizaron pruebas no paramétricas para comparar las diferencias entre los grupos. A partir de la sesión 3 de tratamiento se observó una diferencia significativa en la cantidad de leche extraída y de los perímetros mamarios, cuando comparamos el GDLM con el GMC (p>0,05). En contraste, el dolor fue menor en el GMC comparado con el GDLM y el GC (p>0,05). El GC presentó niveles superiores del dolor y menor cantidad de leche en comparación con los grupos experimentales (p>0,05). Estos resultados sugieren que el tratamiento ideal consistiría en combinar el MC con el DLM. Además, la aplicación de estas técnicas manuales no invasivas puede ser beneficiosas en el puerperio, debido a que evitan el consumo de medicamentos cuyos efectos pueden ser transmitidos al bebé.

The enhancement of ubiquitous and pervasive computing brings new perspectives in terms of medical rehabilitations. In that sense, the present study proposes a Web-based platform to promote the reeducation of patients after hip replacement surgery. This project focuses on two fundamental aspects in the development of a suitable telerehabilitation application, which are: (i) being based on an affordable technology and (ii) providing the patients with a real-time assessment of the correctness of their movements. A comparative test shows that the movement's evaluation carried out by therapists is consistent with the output of the automatic assessment module. Improvements of the algorithm are discussed, in order to increase the accuracy and depth of the analysis.
