This investigation analyzed the effect of rest interval length on the rating of perceived exertion (RPE) during a resistance exercise session. Nineteen males performed two experimental sessions: resistance exercise with 30-sec. rest intervals (E30) and 90-sec. rest intervals (E90). In both sessions, five exercises (bench press, knee extension, seated row, knee curl, and frontal rise) were performed at 50% 1RM in three sets of 12, 9, and 6 repetitions, respectively. In the E30 session, the RPE increased between sets in all exercises, while in the E90 session, the RPE increased from the first set to the second set in three exercises. RPE in the E30 session was higher than that in the E90 session in the third set. The results suggest that RPE increases for shorter rest intervals than for longer rest intervals. Therefore, the RPE could be considered an indicator of muscle recovery during resistance exercise.

Objective: To analyze scientific evidence on the use of blenderized tube feeding in children regarding nutritional composition, family satisfaction, and health outcomes. Data source: Survey was conducted in the PubMed, Scopus, Embase, and Virtual Health Library (VHL) databases using the following search terms: blenderized tube feeding OR blended tube feeding OR homemade OR pureed AND enteral nutrition AND enteral tube. The methodological quality of the selected articles was evaluated using the Critical Appraisal Skill Programme and Hierarchical Classification of Evidence. Data synthesis: After analysis, 11 articles were included in the present review. Most studies demonstrated improvements in health outcomes and greater family satisfaction after replacing the commercial enteral feeding with blenderized tube feeding. Conclusions: When guided and monitored by the healthcare team, a blenderized tube feeding ensures an adequate nutritional composition. The use of this method is also associated with positive health outcomes such as reductions in gastrointestinal symptoms and hospitalizations. Moreover, a high frequency of family satisfaction was verified.%

The aim of this study was to investigate the relationship between physical fitness and the indicators of quality of life in individuals with intermittent claudication (IC). Forty-two subjects (65.2 ± 8.3 years) with IC of both genders participated in the study. Exercise treadmill test, to assess claudication distance (CD) and total walking distance (TWD), and one repetition maximum knee extension test were used to evaluate physical fitness. The quality of life indicators were obtained from the Medical Outcome Study Questionnaire Short Form, which is composed of eight domains: physical functioning (PF), physical aspects (PA), pain, general health, vitality (VI), social functioning (SF), emotional aspects (EA) and mental health. For statistical analysis Pearson correlation coefficient was used, with p < 0.05. There was a significant correlation between PF and CD and TWD (r = 0.60, p < 0.01 and r = 0.49; p < 0.01, respectively), between RP and TWD (r = 0.46, p < 0.01), between VI and SF and CD (r = 0.34, p = 0.03 e r = 0.33, p = 0.04; respectively), and between EA and CD and TWD (r = 0.43, p = 0.01 and r = 0.44, p = 0.01; respectively). In conclusion, the results of this study suggest that indicators of quality of life, both related to physical health and emotional health, are correlated with the walking capacity in patients with IC.

This study aimed to examine the effects of 12 weeks of strength training (ST) on sleep quality and daytime sleepiness in adolescents with sleep complaints. Thirty adolescents were randomly assigned to 2 groups: ST group (ST, n 5 18) and control group (CG, n 5 12). Anthropometric, body composition, one-repetition maximum test, and sleep parameters (Pittsburgh Sleep Quality Index [PSQI] and Epworth Sleepiness Scale [ESS]) were evaluated. Training consisted of 55 min•d 21 (3 times a week, for 12 weeks), 3 sets of 10-12 repetitions with a 1-minute rest interval between sets and exercises. Baseline and postintervention differences were analyzed using Generalized Estimating Equations and the effect size (ES) with Cohen's d coefficient. Significance was set at (p , 0.05). After 12 weeks of ST, a significant decrease in the PSQI score (7.3 6 0.7 vs. 5.1 6 0.6; ES 5 4.10) was observed in the ST group, but not in the CG (6.3 6 0.8 vs. 7.4 6 0.7; ES 5 1.53). A significant decrease in ESS score was found in the ST group (10.1 6 0.7 vs. 8.2 6 0.7; ES 5 3.08), without differences in the CG (10.7 6 0.8 vs. 11.0 6 0.7; ES 5 0.56). The ST group presented increased total sleep duration (h•min 21 ) (6.2 6 0.2 vs. 6.9 6 0.2; ES 5 3.60), but not the CG (7.0 6 0.2 vs. 6.8 6 0.1; ES 5 1.32). Individual analyses showed 67% of adolescents experienced a reduction in PSQI (8.3; confidence interval [CI] 95% 6.8-10.1) and ESS (8.3; CI 95% 6.7-9.9) scores after ST, whereas only 17% of control subjects presented reduced scores (PSQI [11.1; CI 95% 9.5-12.9] and ESS [11.0;). Strength training improved sleep quality and increased total sleep duration.
