Cross-cultural adaptation to the Brazilian Portuguese language of the Waisman Activities of Daily Living (W-ADL) for adolescents and adults with developmental disabilities
In conclusion, the two versions of the Portuguese version of the W-ADL Scale (15 items and 17 items) demonstrated the acceptable validity and reliability measurement to evaluate ADL for adolescents and adults with developmental disabilities. However, the 15-item version seems to be the best option for Portuguese language speakers. (Source: Sport Sciences for Health)

Effect of different phases of menstrual cycle in heart rate variability of physically active women
In this study 19 women had participated, reporting their physical activity status (very active according to the International Physical Activity Questionnaire) and menstrual cycle period. Spectral analysis of HRV was used to calculate low-frequency or LF (0.04 –0.15 Hz) and high frequency or HF (0.15–0.4 Hz). Normalized LF and HF components of R–R variability were considered, respectively, as markers of cardiac sympathetic and parasympathetic modulation, and the ratio between them (LF/HF) was considered as an index of the autonomic modulation of t he heart. For the determination of the follicular...

Short duration static stretching preceded by cycling warm-up reduces vertical jump performance in healthy males
AbstractPurposeIt has been proposed that warm-up activities including static stretching may have detrimental effects on power performance. While it is well established in the literature that more than 30  s of stretching before exercise induces deficit in force and power production, there are still controversial findings regarding 30 s or less when additional interventions, such as general warm-up, are allied to the stretching. Therefore, the purpose of this study was to evaluate the acute effect of passive static stretching preceded by dynamic warm-up on vertical jump performance.MethodsTwenty healthy men partic...

Effects of resistance training on oxidative stress-related biomarkers in metabolic diseases: a review
AbstractSocial and behavioral patterns of physical activity and diet have contributed to the increased incidence of obesity, due to high caloric intake associated to low physical activity. This metabolic impairment can give rise to the occurrence of oxidative stress, which is a key factor in pathogenesis of several metabolic diseases such as metabolic syndrome or type 2 diabetes mellitus (T2DM). Previous studies have reported reduced blood levels of oxidative stress biomarkers and related clinical parameters in obesity, T2DM and metabolic syndrome, following endurance exercise.

AbstractCircadian rhythms influence our daily behavior. Individuals display preferences for activity at certain time of day and this circadian phenotype can be summarized with the concept of “chronotype” or circadian typology (CT). The chronotypes differ in the timing of many physiological and psychological variables. Individuals with an early circadian phase are morning-types (M-types), those with a delayed circadian phase are evening-types (E-types), and those with an intermediate circadian phase are neither-types (N-types). Nevertheless, the propensity toward morning or evening preferences can vary during th...
