Six high-intensity interval training sessions over 5 days increases maximal oxygen uptake, endurance capacity, and sub-maximal exercise fat oxidation as much as 6 high-intensity interval training sessions over 2 weeks

Abstract: Highlights This is the first study showing that 6 high-intensity interval training (HIIT) sessions over just 5 days is just as effective in increasing maximal oxygen uptake and endurance capacity and is more effective at improving submaximal exercise fat oxidation than 6 HIIT sessions over 2 weeks. Five days of HIIT that lasts 60 min in total may be a potent stimulus to improve exercise performance and substrate oxidation. Our findings reveal that this pro… Show more

“…VO 2max [37], endurance capacity [38,39], resting metabolic rate [40], substrate metabolism [41,42], body composition [43], insulin sensitivity [44,45], and cognitive functions [46][47][48]. Besides, interval training has been shown to decrease the risk for cardiovascular diseases [15,25], breast cancer [49], metabolic syndrome [50], osteoarthritis [51,52], and rheumatoid arthritis known to cause lower back pain [53][54][55][56][57] (Figure 1).…”

“…Due to its time-saving nature and the induced physiological adaptations similar to MICT, HIIT has been ranked first in 2018 [ 35 ] and third in 2019 in Worldwide Fitness Trends [ 36 ]. Growing evidence-based research, both original research and meta-analysis studies, shows that interval training programs ranging from 5 days to 12 months are effective in improving O 2max [ 37 ], endurance capacity [ 38 , 39 ], resting metabolic rate [ 40 ], substrate metabolism [ 41 , 42 ], body composition [ 43 ], insulin sensitivity [ 44 , 45 ], and cognitive functions [ 46 , 47 , 48 ]. Besides, interval training has been shown to decrease the risk for cardiovascular diseases [ 15 , 25 ], breast cancer [ 49 ], metabolic syndrome [ 50 ], osteoarthritis [ 51 , 52 ], and rheumatoid arthritis known to cause lower back pain [ 53 , 54 , 55 , 56 , 57 ] ( Figure 1 ).…”

“…Therefore, researchers should not worry as to whether a given load can influence the capacity of individuals to attain _ VO 2max . _ VO 2max is accepted to be a strong predictor of endurance performance [44] and cardiovascular health in clinical patients [2,45,46]. The measure has a history dating back to 1923 and to the pioneering work of Hill and Lupton [39,47].…”

“…A typical HIIT protocol is considered as sprint interval training (SIT), in which individuals will have to complete “all-out” several times (≥100% maximal workload capacity) performance with recovery time in between the intensive exercise sessions on a cycle ergometer [ 55 ]. Therefore, a customized low-volume HIIT protocol (near the maximal corresponding to ≥75% to <100% of maximal workload capacity effort) has been widely utilized by ample studies [ 95 , 96 ] and is prone to be more workable for individuals than the Wingate-based HIIT model [ 55 ].…”
