“…A study comparing supervised and unsupervised HIIT interventions in healthy adults [ 31 ] showed that supervised interventions produced greater improvements in cardiorespiratory fitness, but unsupervised interventions still produced significant improvements. Another study of unsupervised HIIT in which participants exercised alone also showed improvements in cardiorespiratory fitness [ 32 ].…”

“…It is best to use a physiological index to calculate exercise intensity during HIIT, but Mijwel et al used a rating of perceived exertion of 16 to 18 in their study. Past studies of home-based HIIT interventions that used the “talk test” (intensity should be great enough that talking is difficult) [ 32 ] or a modified Borg scale score of 6 to 8 (“very hard”) [ 34 ] as an indicator of exercise intensity showed significant improvement in the primary endpoint of cardiorespiratory fitness. Therefore, even though Mijwel et al may have used a slightly lower or unclear exercise intensity for HIIT compared with other studies, that intensity may have been sufficient to increase VO 2 max.…”

High-intensity interval training in breast cancer survivors: a systematic review

Background To review the settings and outcomes of high-intensity interval training (HIIT) interventions for breast cancer survivors, and to explore the feasibility of prescribing exercise for breast cancer survivors. Methods A systematic search of electronic databases was conducted for studies published up to May 31, 2020. Eligibility criteria included randomized controlled trials of HIIT intervention in breast cancer survivors. Studies were grouped by whether the intervention was conducted during or after breast cancer treatment, and intervention methods and outcomes were reviewed within each group. Results Twenty-six studies were identified, and 13 satisfied the inclusion criteria. Intervention was conducted during treatment in 8 studies, and after treatment in 5. Intervention duration ranged from 3 to 16 weeks, with 2 or 3 sessions per week, for a total of 9 to 36 sessions. All interventions were supervised; 12 were lab-based, and 1 was community-based. One of most promising outcomes was improvement of cardiorespiratory fitness by HIIT. Conclusion This review found that all studies on HIIT for breast cancer survivors investigated lab-based, supervised interventions, but not home-based or unsupervised. HIIT is a time-efficient method for increasing cardiovascular function in breast cancer survivors, but further research is necessary to determine its effects on other outcomes.

“…Our study is in line with these findings because we found minimal side effects from tDCS or HISTT. Beyond safety, the feasibility of home-based tDCS [65] and HIIT interventions [66] in chronic stroke suggests that these interventions could easily translate to clinical practice.…”

Background: Stroke survivors experience chronic gait impairments, so rehabilitation has focused on restoring ambulatory capacity. High-intensity speed-based treadmill training (HISTT) is one form of walking rehabilitation that can improve walking, but its effectiveness has not been thoroughly investigated. Additionally, cortical priming with transcranial direct current stimulation (tDCS) and movement may enhance HISTT-induced improvements in walking, but there have been no systematic investigations. The objective of this study was to determine if motor priming can augment the effects of HISTT on walking in chronic stroke survivors. Methods: Eighty-one chronic stroke survivors participated in a controlled trial with stratification into four groups: 1) control-15 min of rest (n = 20), 2) tDCS-15 min of stimulation-based priming with transcranial direct current stimulation (n = 21), 3) ankle motor tracking (AMT)-15 min of movement-based priming with targeted movements of the ankle and sham tDCS (n = 20), and 4) tDCS+AMT-15 min of concurrent tDCS and AMT (n = 20). Participants performed 12 sessions of HISTT (40 min/day, 3 days/week, 4 weeks). Primary outcome measure was walking speed. Secondary outcome measures included corticomotor excitability (CME). Outcomes were measured at pre, post, and 3-month follow-up assessments. Results: HISTT improved walking speed for all groups, which was partially maintained 3 months after training. No significant difference in walking speed was seen between groups. The tDCS+AMT group demonstrated greater changes in CME than other groups. Individuals who demonstrated up-regulation of CME after tDCS increased walking speed more than down-regulators. Conclusions: Our results support the effectiveness of HISTT to improve walking; however, motor priming did not lead to additional improvements. Upregulation of CME in the tDCS+AMT group supports a potential role for priming in enhancing neural plasticity. Greater changes in walking were seen in tDCS up-regulators, suggesting that responsiveness to tDCS might play an important role in determining the capacity to respond to priming and HISTT.
