Abstract
Santiago, LCS, Lyra, MJ, Germano-Soares, AH, Lins-Filho, OL, Queiroz, DR, Prazeres, TMP, Mello, MT, Pedrosa, RP, Falcão, APST, and Santos, MAM. Effects of strength training on sleep parameters of adolescents: a randomized controlled trial. J Strength Cond Res XX(X): 000-000, 2020-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 = 18) and control group (CG, n = 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 (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 ± 0.7 vs. 5.1 ± 0.6; ES = 4.10) was observed in the ST group, but not in the CG (6.3 ± 0.8 vs. 7.4 ± 0.7; ES = 1.53). A significant decrease in ESS score was found in the ST group (10.1 ± 0.7 vs. 8.2 ± 0.7; ES = 3.08), without differences in the CG (10.7 ± 0.8 vs. 11.0 ± 0.7; ES = 0.56). The ST group presented increased total sleep duration (h·min) (6.2 ± 0.2 vs. 6.9 ± 0.2; ES = 3.60), but not the CG (7.0 ± 0.2 vs. 6.8 ± 0.1; ES = 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 participants presented reduced scores (PSQI [11.1; CI 95% 9.5-12.9] and ESS [11.0; CI 95% 9.4-12.6]). Strength training improved sleep quality and increased total sleep duration.

Abstract
BACKGROUND Impaired microcirculation is associated with poor walking capacity in symptomatic peripheral artery disease (PAD) patients during treadmill test; however, this test does not simulate the efforts of daily walking of these patients. Thus, the aim of the study was to describe the microcirculation responses during a 6-minute walk test (6MWT) and to analyze the relationship between microcirculation indicators and walking impairment in symptomatic PAD patients. METHODS Thirty-four patients were included (mean age = 67.6 ± 11.2 years). Their clinical characteristics were collected, and they performed a 6MWT, in which the initial claudication distance (ICD) and total walking distance (TWD) were recorded. During and after the 6MWT, calf muscle oxygen saturation (StO2) parameters were monitored continuously to measure microcirculation behavior. The association between calf muscle StO2 parameters and walking impairment were analyzed by Pearson or Spearman correlations. RESULTS Walking impairment was not associated with any StO2 parameters during exercise. In contrast, after 6MWT, recovery time of StO2 (r = -0.472, P = 0.008) and recovery time to maximal StO2 (r = -0.402, P = 0.019) were negatively correlated with ICD. Furthermore, the distance walked under claudication symptoms (ΔTWD-ICD) was positively correlated with recovery time to maximal StO2 (r = 0.347, P = 0.048). CONCLUSIONS In symptomatic PAD patients, shorter ICD values during a 6MWT are associated with a delayed recovery in calf muscle StO2 after exercise. Calf muscle StO2 parameters decrease subtly during 6MWT, suggesting that the degree of ischemia in the calf muscle during ground walking, simulating efforts of the daily walking, is relatively low.

Abstract
The aim of this study was to describe, through a systematic review, the acute and chronic effects of isometric handgrip exercise on cardiovascular variables in hypertensive individuals. In this systematic review, we included studies that analyzed whether a single bout or a program with isometric exercises affect cardiovascular variables in hypertensive adults. The electronic database PubMed/Medline was searched for relevant studies published until May 2017. Of the 2927 studies initially identified, 2916 were excluded based on title and abstract and five on the basis of full-text assessment, leaving six studies remaining. In addition, one further study cited in the references of the included articles was included in this review, totaling seven studies included (five studies on the chronic effects of isometric handgrip exercise on cardiovascular parameters). None of the acute studies observed post-exercise hypotension. The majority of the chronic studies found decreases in office blood pressure after isometric handgrip training, with training ranging from 6 to 10 weeks, while heart rate variability parameters were improved in one study and did not change in another. Reduction in oxidative stress was observed; however, this variable was only analyzed in one study. In hypertensives, acute responses to isometric handgrip exercise are very limited due to the small number of studies, therefore more research is required. Furthermore, chronic isometric handgrip training reduces blood pressure; however, there is still a gap in the knowledge on the effects of this modality of exercise on other cardiovascular variables—such as endothelial function, oxidative stress, and cardiac autonomic modulation—which should be addressed in future studies.
