Background. One of the most popular high-intensity interval exercises is the called ”Tabata Protocol”. However, most investigations have limitations in describing the work intensity, and this fact appears to be due to the protocol unfeasibility. Furthermore, the physiological demands and energetic contribution during this kind of exercise remain unclear. Methods. Eight physically active students (21.8

The aim of the present study was to evaluate the effects of 5 month kettlebell-based training on jumping performance, balance, blood pressure and heart rate in female classical ballet dancers. It was a clinical trial study with 23 female dancers (age = 21.74 ± 3.1 years; body height = 168.22 ± 5.12 cm; body mass

We compared the effects of body-weight resistance training (BWT), at moderate or high-speed conditions, on muscle power, velocity of movement, and functional performance in older females. In a randomized single-blinded non-controlled trial, participants completed twelve weeks (three sessions/week) of BWT, at high (HST; n=14; age, 70.6±4.3 years) or moderate (MST; n=12; age, 72.8±4.2 years) speeds.

Background: The present study aimed to compare changes in muscle size when measured by ultrasound (MT, muscle thickness) and arm circumference (AC) using data from young men. Methods: The investigation involved data from 3 previous studies involving a total 67 young men who performed resistance training (RT) for 10-12 weeks. Before and after the training

In December of 2019, there was an outbreak of a severe acute respiratory syndrome caused by the coronavirus 2 (SARS-CoV-2 or COVID-19) in China. The virus rapidly spread into the whole world causing an unprecedented pandemic and forcing governments to impose a global quarantine, entering an extreme unknown situation. The organizational consequences of quarantine/isolation are

Aerobic exercise is traditionally recommended to improve general health and prevent many non-communicable diseases. However, the measures adopted to control the novel Coronavirus (COVID-19) outbreak culminated with closing of exercise facilities and fitness centers and, as a primary consequence, impaired aerobic exercise practice. This contributed to an increase in risk factors associated with physical inactivity
