Functional assessment of respiratory muscles and lung capacity of CrossFit athletes.

CrossFit is a high-intensity training related to physical fitness and respiratory capacity that can promote changes in lung function. This cross-sectional study was aimed at evaluating respiratory muscle strength, electromyographic (EMG) activity, and lung capacity in CrossFit athletes. Thirty subjects aged between 25 and 35 years were divided into groups: CrossFit athletes (n=15) and sedentary individuals without comorbidities (n=15).

Effects of Acupuncture at the Yintang and the Chengjiang Acupoints on Cardiac Arrhythmias and Neurocardiogenic Syncope in Emergency First Aid.

This study evaluated the effectiveness of YinTang and ChengJiang acupoints on patients with cardiac arrhythmia and neurocardiogenic syncope in emergency first aid. A 45 year old woman underwent acupuncture. She had a previous history of a valvuloplasty for rheumatic disease and two acute myocardial infarctions, followed by four catheterizations and an angioplasty.

Relationship between exercise capacity and quality of life in adolescents with asthma.

Objective: To determine whether the quality of life of adolescents with asthma correlates with parameters obtained prior to and after the six-minute step test (6MST); spirometric results after the 6MST; and level of physical activity.

Methods: Nineteen adolescents with asthma, ranging from 11-15 years of age, were assessed with spirometry, 6MST, the International Physical Activity Questionnaire (IPAQ), the Pediatric Asthma Quality of Life Questionnaire (PAQLQ), and the 10-point Borg category-ratio (CR10) scale.

Results: Sensation of dyspnea correlated negatively with the total PAQLQ score (r = -0.

Relationship of BODE Index to functional tests in chronic obstructive pulmonary disease.

Objective: To determine if there is a correlation between the BODE Index and variables assessed during the Activities of Daily Living assessment, performance on lower limber tests, and peripheral muscle impairment of the upper limb in patients with chronic obstructive pulmonary disease.

Materials And Methods: Ten men (aged 58 to 80 years old) with moderate to very severe obstruction were evaluated and classified by the BODE Index. They were evaluated by pulmonary ventilation (VE), oxygen consumption (VO2), and carbonic gas production (VCO2) on the ADL assessment; Distance Walking (DW) in the Six Minute Walking Test (6MWT) and the Six Minute Walking Test on Treadmill (6MWTT); number of repetitions in the Sit-to-Stand Test; and the Hand Grip Strength Test.

[Analysis of metabolic and ventilatory demand during the execution of daily life activities in individuals with chronic obstructive pulmonary disease].

Individuals with Chronic Obstructive Pulmonary Disease (COPD) report that fatigue and dyspnea are the main symptoms experienced as a result of efforts made during the realization of daily life activities (DLA). Based on this context, this study aimed to analyze and compare individuals with COPD (FEV1<60%), classified as Group 1 (G1) and healthy individuals, classified as Group 2 (G2), during the execution of five DLA. The chosen DLA were: changing a light bulb (L); lifting a weight (LW); sweeping (S); climbing steps (CA) and walking on a treadmill (WT).
