The Impact

Introduction: Over the last decade, research into the impact of school-based high-intensity interval training (HIIT) on young people's health has markedly increased. Despite this, most authors have focused on the outcomes of their intervention, rather than the process of how the study was conducted. The aim of our study, therefore, was to conduct a mixed methods process evaluation of Project FFAB (Fun Fast Activity Blasts), a school-based HIIT intervention for adolescents. The objectives were to explore study recruitment, reach, intervention dose, fidelity, participants' experiences, context, and future implementation.Methods: Recruitment was assessed by comparing the number of students who received study information, to those who provided consent. Reach was described as the number of participants who completed the intervention. Dose was reported via the number of HIIT sessions delivered, total exercise time commitment, HIIT exercise time, and session attendance. Post-intervention focus groups were conducted with intervention participants (n = 33; aged 14.1 ± 0.3 years; mean ± standard deviation). These discussions explored aspects of intervention fidelity (extent that the intervention was delivered as intended); participants' experiences of the HIIT sessions; context (exploration of the nuances of school-based HIIT); and ideas for future implementation.Results: Recruitment, reach, and dose data indicate that Project FFAB was largely delivered as planned. Focus group data identified a mismatch between perceived vs. prescribed work: rest ratio for the multi-activity HIIT drills. Generally, the HIIT drills were well-received; participants often reported they were fun to complete, and the use of heart rate monitors was helpful for interpreting exercise intensity. Some participants stated that greater variety in the HIIT drills would be preferable. The timing and structure of the HIIT sessions that took place outside of physical education lessons received mixed responses.Conclusion: Collectively, our study supports the use of school-based HIIT and provides valuable insights into how such interventions can be implemented. Project FFAB could be modified to account for individuals' preferences on when the exercise sessions took place. In addition, a wider range of activities could be included, and the prescribed work: rest ratio of the HIIT drills could be better communicated.

Cancer Of The Lung

Background: Pre-operative fitness is an established predictor of postoperative outcome; accordingly, targeting pre-operative fitness through exercise prehabilitation has logical appeal. Exercise prehabilitation for patients with cancer of the lung or oesophagus is challenging to implement due to the short opportunity for intervention between diagnosis and surgery. In addition, there are now additional challenges to providing prehabilitation during the coronavirus disease 2019 (COVID-19) pandemic due to concerns about social distancing and minimising patient contact. The PRE-HIIT project will examine the influence of virtually delivered exercise prehabilitation on physiological outcomes and postoperative recovery. Methods: The PRE-HIIT randomised controlled trial (RCT) will compare a 2-week high intensity interval training programme to standard preoperative care in a cohort of patients with thoracic and oesophageal cancers. A protocol for this study has been published previously. As a result of the COVID-19 pandemic, changes to the study assessment battery and the mode of intervention delivery have been made. The PRE-HIIT programme will now be a home-based intervention. Both the exercise intervention and standard care will be delivered via telehealth. The recruitment target for the study remains 78 participants. There is no change to the primary outcome of the study; cardiorespiratory fitness. Secondary outcomes include measures of pulmonary and physical function, quality of life and post-operative morbidity. Outcomes will be measured at baseline and post-intervention. The impact of PRE-HIIT on well-being will be examined qualitatively with interviews post-intervention (T1). This revised protocol will also explore participant’s satisfaction with delivery of prehabilitation via telehealth. The healthcare costs associated with the PRE-HITT programme will also be examined. Discussion: The overall aim of this RCT is to examine the effect of tailored, individually prescribed high intensity interval training on pre-operative fitness and postoperative recovery for patients undergoing complex surgical resections.

Background: Low- and moderate-intensity exercise training has been shown to be effective for reducing general anxiety and anxiety sensitivity among adults with asthma. Exercise frequency and intensity have been shown to play an integral role in reducing anxiety sensitivity; however, less is known about the impact of high-intensity interval training (HIIT) on anxiety in adults with asthma. Methods: A 6-week HIIT intervention was conducted with adults with asthma. Participants completed HIIT (10% peak power output for 1 min, 90% peak power output for 1 min, repeated 10 times) 3 times per week on a cycle ergometer. Preintervention and postintervention assessments included the Anxiety Sensitivity Index-3 and the Body Sensations Questionnaire. Results: Total Anxiety Sensitivity Index-3 (PRE: 17.9 [11.8]; POST 12.4 [13], P = .002, Cohen d = 0.4, n = 20) and Body Sensations Questionnaire (PRE: 2.4 [1.0]; POST: 2.0 [0.8], P = .007, Cohen d = 0.3) improved from preintervention to postintervention. Conclusion: A 6-week HIIT intervention leads to improved anxiety among adults with asthma. Future research should determine the impact of HIIT among adults with asthma with clinical anxiety.

Abstract Context Aerobic exercise training can increase brain volume and blood flow, but the impact on brain metabolism is less known. Objective We determined whether high-intensity interval training (HIIT) increases brain metabolism by measuring brain glucose uptake in younger and older adults. Design Brain glucose uptake was measured before and after HIIT or a sedentary (SED) control period within a larger exercise study. Setting Study procedures were performed at the Mayo Clinic in Rochester, MN. Participants Participants were younger (18 to 30 years) or older (65 to 80 years) SED adults who were free of major medical conditions. Group sizes were 15 for HIIT (nine younger and six older) and 12 for SED (six younger and six older). Intervention Participants completed 12 weeks of HIIT or SED. HIIT was 3 days per week of 4 × 4 minute intervals at over 90% of peak aerobic capacity (VO2peak) with 2 days per week of treadmill walking at 70% VO2peak. Main Outcome Measures Resting brain glucose uptake was measured using 18F-fluorodeoxyglucose positron emission tomography scans at baseline and at week 12. Scans were performed at 96 hours after exercise. VO2peak was measured by indirect calorimetry. Results Glucose uptake increased significantly in the parietal-temporal and caudate regions after HIIT compared with SED. The gains with HIIT were not observed in all brain regions. VO2peak was increased for all participants after HIIT and did not change with SED. Conclusion We demonstrate that brain glucose metabolism increased after 12 weeks of HIIT in adults in regions where it is reduced in Alzheimer’s disease.

The Impact

The COVID-19 pandemic and subsequent self-isolation exacerbated the problem of insufficient amounts of physical activity and its consequences. At the same time, this revealed the advantage of vitamin D. Thus, there was a need to verify the effects of those forms of training that can be performed independently. In this study, we examined the effects of Nordic walking (NW) and high intensity interval training (HIIT) with regard to the impact of the metabolite vitamin D. We assigned 32 overweight adults (age = 61 ± 12 years) to one of two training groups: NW = 18 and HIIT = 14. Body composition assessment and blood sample collection were conducted before starting the training programs and a day after their completion. NW training induced a significant decrease in myostatin (p = 0.05) concentration; however, the range was dependent on the baseline concentrations of vitamin D metabolites. This drop was accompanied by a significant negative correlation with the decorin concentration. Unexpectedly, NW caused a decrement in both forms of osteocalcin: undercarboxylated (Glu-OC) and carboxylated-type (Gla-OC). The scope of Glu-OC changes was dependent on a baseline concentration of 25(OH)D2 (r = −0.60, p = 0.01). In contrast, the HIIT protocol did not induce any changes. Overall results revealed that NW diminished the myostatin concentration and that this effect is more pronounced among adults with a sufficient concentration of vitamin D metabolites.

The Impact

Physical inactivity remains one of the biggest societal challenges of the 21st century. The gaming industry and the fitness sector have responded to this alarming fact with game-based or gamified training scenarios and thus established the promising trend of exergaming. Exergames—games played with the (whole) body as physical input—have been extolled as potential attractive and effective training tools. Simultaneously, researchers and designers are still exploring new approaches to exploit the full potential of this innovative and enjoyable training method. One way to boost the attractiveness and effectiveness of an exergame is to individualize it with game adaptations. A physiological parameter that is often used to balance the physical challenge and intensity of exergames to the player’s fitness skills is the heart rate (HR). Therefore, researchers and designers often rely on age-based, maximum HR (HRmax) formulas originating from performance diagnostics. In combination with the player’s assessed real-time HR during an exergame session, the pre-determined HRmax is used to adapt the game’s challenge to reach a pre-defined HR and physical intensity level (in-exergame adaptations), respectively. Although the validity and reliability of these age-based HRmax formulas were proven in heterogeneous target populations, their use is still often criticized as HR is an individual parameter that is affected by various internal and external factors. So far, no study has investigated whether the formula-based pre-calculated HRmax compared to a standardized individually pre-assessed HRmax elicits different training intensities, training experiences, and flow feelings in an exergame. Therefore, we compared both variants for in-exergame adaptation with the ExerCube – a functional high-intensity interval training exergame – in healthy young adults. Comparing the results of the two conditions, no significant differences were found for HR parameters and perceived physical and cognitive exertion, nor for overall flow feelings and physical activity enjoyment. Thus, the formula-based in-exergame adaptation approach was suitable in the presented study population, and the ExerCube provided an equally reliable in-exergame adaptation and comparable exergame play experiences. We discuss our findings in the context of related work on exergame adaptation approaches and draw out some implications for future adaptive exergame design and research topics.

Lifestyle Education

This study assessed the feasibility and benefits of high intensity interval training (HIIT) plus lifestyle education among inactive adults with celiac disease. 41 participants were randomized to receive the intervention (HIIT+) for 12-weeks or waitlist control (WLC). Testing was completed at baseline, immediately post- and 3-months post-intervention. Generalized estimating equations were used to assess changes in the outcome variables over time between the groups. Mean percent of age-predicted maximum heart rate was 97.9% and average rating of perceived exertion (RPE) was 6.33 (out of 10) during HIIT intervals. Following the intervention, the HIIT+ group showed enrichment in relative abundance of Parabacteroides and Defluviitaleaceae_UCG¬_011 while WLC showed enrichment in relative abundance of Roseburia intestinalis, Klebsiella and Adlercreutzia. A unique set of taxa were differentially abundant between the groups at 3-months post-intervention. HIIT+ participants experienced a reduction in resting heart rate (-6.6 bpm) immediately post-intervention compared to WLC. Further research is needed to establish an optimal HIIT protocol that may improve VO2max and metabolic syndrome biomarkers. Findings from this pilot study provide preliminary evidence that a HIIT+ intervention is feasible for inactive adults with celiac disease and leads to favourable changes in resting HR alongside potentially beneficial shifts in gut microbiota. Trial registration number: ClinicalTrials.gov number NCT03520244 Novelty • High intensity interval training leads to potentially beneficial changes in the gut microbiota of adults with celiac disease. • A high intensity interval training exercise intervention is feasible and well tolerated for patients with celiac disease.
