High-Intensity Interval Training Improves Cognitive Flexibility in Older Adults

Abstract: Introduction: Regular aerobic exercise is associated with better executive function in older adults. It is unclear if high-intensity-interval-training (HIIT) elicits moderate-intensity continuous training (MICT) or resistance training (RT). We hypothesized that HIIT would augment executive function more than MICT and RT. Methods: Sixty-nine older adults (age: 68 ± 7 years) performed six weeks (three days/week) of HIIT (2 × 20 min bouts alternating between 15 s intervals at 100% of peak power output (PPO) and p… Show more

“…Strengths of the study include our large study sample of cognitively impaired and inactive patients, and our long and intense (partly) supervised exercise training, including high intensity interval training [47,48]. Additionally, our patients showed good adherence to the exercise program and physical fitness improved following the exercise intervention.…”

“…Peak oxygen uptake increased post-intervention in the training group. Not given Mekari et al (2020) [ 35 ] Frequency: 3×/week for 6 weeks Intervals: 15-s intervals at 100% PPO Rest: 15-s passive recovery at 0% PPO Modality: Cycle ergometer VO 2max significantly improved in all groups following training, but HIIT and MCT improved more than RT. The HIIT group had the greatest improvement in VO 2max .…”

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 ).…”
