Será a combinação dos treinamentos intervalado e resistido mais efetiva sobre a aptidão física em adultos? Uma revisão sistemática e metanálise

Abstract

-Interval training (HIIT / SIT) combined with resistance training (RT) has been highlighted as a strategy for the improvement of health-related physical fitness markers (HRPF) in adults. Thus, the aim of this meta-analysis was to compare the efficacy of combined training (HIIT / SIT + RT) with other exercise protocols on HRPF markers in adults. A systematic search was performed in MEDLINE via PebMed, Cochrane-CENTRAL, SPORTDiscus, LILACS, SCIELO and Scopus databases between January and March 2017, using the following keywords in English and Portuguese: physical fitness, high-intensity interval training, sprint interval training, resistance training and adults. The quality of studies was evaluated using the PEDro scale. After applying both inclusion and exclusion criteria, nine articles were selected (n = 231). The extraction of means and standard deviations from studies was performed independently by two authors and the RevMan software was used to perform the meta-analysis. Combined training interventions lasted from 6 to 12 weeks and generated greater increase in maximal oxygen uptake than other forms of exercise. The combination of interval training and strength training may be considered more effective to improve aerobic capacity levels in adults.Key words: Adults; High-intensity interval training; Physical fitness; Resistance training; Sprint interval training.

Effect of combined interval training on the cardiorespiratory fitness in heart failure patients: a systematic review and meta-analysis

“…15,16 Among the principles that IT follows, we can mention sprint interval training (SIT) and high-intensity interval training (HIIT). 17 SIT is composed of sprints that last between 8 and 30 s at an intensity of 100% of VO 2max , while HIIT is characterized by sets of efforts lasting between 60 and 240 s, with intensity greater than 80% of VO 2max . 14,17 On the other hand, RT is a training protocol that requires muscle work against a load or resistance ---this may be an external load or even body weight.…”
