Exercise-Induced Muscle Damage after a High-Intensity Interval Exercise Session: Systematic Review.

High-intensity interval training (HIIT) is considered an effective method to improve fitness and health indicators, but its high-intensity exercises and the mechanical and metabolic stress generated during the session can lead to the occurrence of exercise-induced muscle damage. Therefore, this study aimed to describe, by means of a systematic review, the effects of a single HIIT session on exercise-induced muscle damage. A total of 43 studies were found in the Medline/PubMed Science Direct/Embase/Scielo/CINAHL/LILACS databases; however, after applying the exclusion criteria, only 15 articles were considered eligible for this review.

Breathing Motion Pattern in Cyclists: Role of Inferior against Superior Thorax Compartment.

The thoracoabdominal breathing motion pattern is being considered in sports training because of its contribution, along with other physiological adaptations, to overall performance.

Muscle Daily Undulating Periodization for Strength and Body Composition: The Proposal of a New Model.

The traditional linear periodization model is designed for modifications to be performed over several weeks, whereas alterations in the undulating model are applied on a more frequent basis. The study investigated a novel periodization scheme, the muscle daily undulating periodization model (mDUP). Thirty-seven men were randomly assigned into 2 groups: (a) a group that performed 12 weeks of daily undulating periodization with fix overload (DUP-F) resistance training ( = 19) and (b) a group that performed 12-weeks of muscle daily undulating periodization with variation overload (mDUP) ( = 18).

Methods: Thirteen women with hypertension (HG; age: 60.

Resistance training promotes reduction in Visceral Adiposity without improvements in Cardiomyocyte Contractility and Calcium handling in Obese Rats.

Resistance training (RT) improves the cardiomyocyte calcium (Ca) cycling during excitation-contraction coupling. However, the role of RT in cardiomyocyte contractile function associated with Ca handling in obesity is unclear. Wistar rats were distributed into four groups: control, sedentary obese, control plus RT, and obesity plus RT.
