Cardiorespiratory response to HIIT variants

High intensity interval training (HIIT) is currently the most widely used training modality globally. The different methodological proposals and the possibilities of adaptation to almost anyone make HIIT a very popular option.   The results of a study have recently been published (Beltrami et al, 2021; Int J Sports Physiol Perform 19-Feb; doi: 10.1123 / …

Effects of HIIT on the functional capacity of football players

Football is characterized by long periods of low to moderate intensity activity interspersed with periods of high intensity, such as single and repeated sprints. In addition, explosive actions, such as acceleration, deceleration, rapid changes of direction and jumps, often occur at key moments in the match. Therefore, a player must be able to endure long …

Effects of high intensity resistance training versus HIIT on cardiometabolic risk factors in overweight people

Cardiovascular and cardiometabolic diseases are the cause of millions of deaths worldwide. Exercise supports a healthy cardiometabolic profile, although the most effective exercise modality in this regard has yet to be determined. Hundreds of investigations have been conducted in the past decade on the effects of high intensity aerobic interval training (HIIT) on cardiometabolic health, …

Effects of HIIT on endothelial function in adolescents

Factors that show aggressiveness towards the endothelium are associated with the development of arteriosclerosis. Exercise can attenuate or prevent this process, but little is known about how high intensity interval training (HIIT) can influence this process in adolescents.   The results of a study have recently been published (da Siiva et al, 2019; Physiol Behav …

¿Running HIIT negatively affects upper limb strength performance?

It is relatively common to use high intensity interval training (HIIT) sessions in the same session as strength training with other muscle groups. The results of a study have recently been published (Andrade et al, 2021; J Sports Med Phys Fitness 61: 803; doi: 10.23736 / S0022-4707.20.11458-0) whose objective was to compare the effects of …

Polarized Training on Muscle Thickness and Anaerobic Power in Cyclists (SIT, HIIT, Aerobic Endurance)

Athletes who participate in aerobic endurance sports, such as running, cycling, and cross-country skiing, use different training modalities to improve athletic performance. Peak performance in aerobic endurance sports has been shown to require a high level of maximal oxygen uptake (VO2max). However, in the previously mentionedsports disciplines, the effort of the competition is characterized by …

Effects of different HIIT workload protocols on the achieved VO2 value in the session

The possibilities when setting up high intensity interval training (HIIT) protocols are very high. Different studies in recent years have shown that there is no single valid configuration, but that the proposed goal can be achieved with different HIIT configurations. The results of a study have recently been published (Wommer et al, 2021; Int J …

¿HIIT and intermittent fasting on body composition and performance in women?

Nutritional strategies can have an effect on body composition and physical performance. Intermittent fasting (IF) is an eating pattern that alternates between periods of eating and fasting for specific periods of time. In addition, it is a common strategy in athletes seeking to lose body fat. However, this strategy can negatively affect physical performance, compared …
