This study aims to compare the acute effects at the cardiovascular (heart rate, blood pressure) and physiological (lactate) levels, as well as the perception of effort and fatigue, of four exercise modalities, one based on the traditional aerobic training methodology, another based on high-intensity interval training (HIIT), another consisting of aerobic exercise performed in conjunction with an immersive virtual reality (VR) application, and a last one consisting of exercise with HIIT-type parameters but also performed in conjunction with an immersive VR application. All participants will complete one session of each of the four exercise modalities, analyzing the variables studied in each for subsequent analysis and comparison.

5 minutes of warm-up at increasing intensity up to 60% of maximum heart rate (HRmax) + 20 minutes between 60-80% of HRmax + 5 minutes of cool-down at decreasing intensity (30-60% HRmax)
5 minutes warm-up at increasing intensity up to 60% maximum heart rate (HRmax) + 20 minutes main part consisting of 10 repetitions of the combination of 1 minute at 75-90% HRmax and 2 minutes of active rest with light pedaling (50% HRmax) + 5 minutes cool-down at decreasing intensity (30-60% HRmax)
5 minutes of warm-up at increasing intensity up to 60% Maximum heart rate (HRmax) + 20 minutes between 60-80% of HRmax + 5 minutes of cooling at decreasing intensity (30-60% HRmax), with the use of virtual reality glasses and an immersive virtual reality application

Blood lactate
Analysis of blood lactate concentration
Time frame: During the 5 minutes after finishing the exercise session of each intervention modality (Days 1, 8, 15 and 22 from the start of the study)
Heart rate pattern
Heart rate pattern, measured with a heart rate monitor
Time frame: During each exercise session (Days 1, 8, 15 and 22 from the start of the study)
Systolic and diastolic blood pressure
Systolic and diastolic blood pressure, measured with a sphygmomanometer
Time frame: During the 5 minutes after finishing the exercise session of each intervention modality (Days 1, 8, 15 and 22 from the start of the study)
Perception of effort
Individual perception of effort during exercise, assessed with a modified Borg scale (0-10), where 0 is "no effort" and 10 corresponds to the "maximum possible perception of effort".
Time frame: During the first minute after finishing the exercise session of each intervention modality (Days 1, 8, 15 and 22 from the start of the study)
Perception of fatigue
Individual perception of fatigue, with a numerical scale from 0 to 10, where 0 is "no fatigue" and 10 corresponds to the "maximum perception of fatigue possible"
Time frame: During the first minute after finishing the exercise session of each intervention modality (Days 1, 8, 15 and 22 from the start of the study)
Physical performance
Physical performance, assessed by calculating the sets, repetitions and kg mobilized during the exercise time.
Time frame: During the 5 minutes after finishing the exercise session of each intervention modality (Days 1, 8, 15 and 22 from the start of the study)
