High-intensity interval training (HIIT)
The HIIT sessions will be performed on cycle ergometers and will be consisted of 10 x 60-s cycling intervals interspersed with 60 s recovery. Individual workloads will be selected to elicit \~90% maximal heart rate attained in the cardiorespiratory fitness test (HRmax). A passive or active recovery will be given among high-intensity stimulus. Each training session will include 3-min warm-up and 2-min cool-down phase performed \~50% (HRmax), totalling 25 min. This intervention will last 10 weeks.
Strength training (ST)
ST protocol will consist of three sets performed at maximum weight that participants could move eight times with good technique in the following exercises: supine bench press (pectoralis major), leg press (quadriceps, biceps femoris, gluteus maximus), lat pulldown (latissimus dorsi), leg extension (quadriceps), shoulder press (deltoids), leg curl (biceps femoris) and abdominal crunch (abdominal muscles). It will be given 1-min rest between series, totalizing approximately 35 min of ST. This intervention will last 10 weeks.
ST combined with HIIT (ST+HIIT)
Participants in the ST+HIIT group will execute ST and HIIT (in this order) above described in the same training session, lasting approximately 60 min. This intervention will last 10 weeks.
