Acute Changes in Interleukin-6 Level During Four Days of Long-Distance Walking.

Background: Interleukin 6 (IL-6) has an inflammatory effect, and its concentration in serum increases during exercise. However, no studies have assessed acute changes in IL-6 concentration after consecutive days of extreme and long-term exercise.

Objective: This study aimed to assess acute changes in serum IL-6 concentration during four days of long-distance walking.

Metabolic syndrome impact on pulmonary function of women.

Background: The presence of metabolic syndrome (MetS) and its components may induce structural and physiological changes that exacerbate the impairment of the respiratory function. The aim of the study is to evaluate the impact of metabolic syndrome and its components on lung function in women.

Methods: This is cross-sectional study.

Evaluation of factors associated with severe and frequent back pain in high school athletes.

Several studies have shown that half of all young athletes experience back pain (BP). However, high intensity and frequency of BP may be harmful, and the factors associated with BP severity have not been investigated in detail. Here, we investigated the factors associated with a high intensity and high frequency of BP in high school athletes.

Use of a backpack alters gait initiation of high school students.

We assessed how backpack carriage influences the gait initiation (GI) process in high school students, who extensively use backpacks. GI involves different dynamics from gait itself, while the excessive use of backpacks can result in adverse effects. 117 high school students were evaluated in three experimental conditions: no backpack (NB), bilateral backpack (BB), and unilateral backpack (UB).

Back Pain Prevalence and Its Associated Factors in Brazilian Athletes from Public High Schools: A Cross-Sectional Study.

Most studies on the prevalence of back pain have evaluated it in developed countries (Human Development Index--HDI > 0.808), and their conclusions may not hold for developing countries. The aim of this study was to identify the prevalence of back pain in representative Brazilian athletes from public high schools.

Effects of four days hiking on postural control.

Hiking is a demanding form of exercise that may cause delayed responses of the postural muscles and a loss of somatosensory information, particularly when repeatedly performed for several days. These effects may negatively influence the postural control of hikers. Therefore, the aim of this study was to investigate the effects of a four-day hike on postural control.

Body composition of chronic renal patients: anthropometry and bioimpedance vector analysis.

Objective: to compare the body composition of patients undergoing hemodialysis with that of healthy individuals using different methods.

Method: cross-sectional study assessing male individuals using anthropometric markers, electrical bioimpedance and vector analysis.

Results: the healthy individuals presented larger triceps skinfold and arm circumference (p<0.

[Evaluation of gait initiation in low risk pregnant women in the three trimesters].

Purposes: To describe the process of gait initiation of pregnant women and to compare the behavior of the pressure center in the three trimesters of pregnancy.

Methods: Fifty-seven low-risk pregnant women were evaluated, aged 18 to 35 years, selected for convenience location during the three trimesters of pregnancy. The women were divided into three groups of 19 subjects each, according to gestational age - 1st quarter (4-12 weeks), 2nd quarter (13-28 weeks), and 3rd quarter (29-42 weeks,).
