High Intensity Interval

Despite growing interest in high-intensity interval training as a time-effective way for older adults to improve their health, there is little consensus regarding the better way to plan a HIIT intervention. Given the loss of function and health problems of an older adult population, the identification and characterization of interventions and strategies is a fundamental prerequisite. The goals of this review are examining high-intensity interval training as a way to improve health, and finding out the highestintensity viable HIIT protocol. Studies were included in this systematic review if: (1) they studied a population of older adults; (2) prescribed an intervention that can be described as high intensity; and (3) reported health-related outcome measures. The resulting 14 papers were included in our study. The present review found that high-intensity interval training is an effective tool to improve indicators of body composition as well as cardiometabolic and cardiovascular health, with 90-95% HRmax cycle ergometer sessions held two-three times a week, with a minimum session length of 40 minutes, in an intervention at least 12-week long, effecting significant improvements on the health of participants. Recommendations regarding optimal exercise duration and rest intervals must remain ambiguous given the scarcity of published literature and the methodology and limitations of those studies that are already available

High Intensity Interval

High-intensity interval training (HIIT) is emerging as a safe and effective means to combat chronic diseases. The objective of this work was to perform a systematic review of the effect of HIIT interventions in an aging population. Three electronic databases were searched for randomized trials comparing the effect of HIIT and moderate-intensity continuous training in older adults. After a thorough screening process, 15 articles were identified as meeting the inclusion criteria. All studies expressed a comparable or superior effect of HIIT in cardiorespiratory fitness measures. No studies reported a lessened effect of HIIT in comparison with moderate-intensity continuous training. This systematic review demonstrates that HIIT is a useful exercise regimen, which can be used in older adults to increase cardiorespiratory fitness. More research is needed to determine the effects of HIIT in an aging, predominately female population.

AbstractChronic lymphocytic leukemia (CLL) is the most common leukemia in the USA, affecting predominantly older adults. CLL is characterized by low physical fitness, reduced immunity, and increased risk of secondary malignancies and infections. One approach to improving CLL patients’ physical fitness and immune functions may be participation in a structured exercise program. The aims of this pilot study were to examine physical and immunological changes, and feasibility of a 12-week high-intensity interval training (HIIT) combined with muscle endurance-based resistance training on older adults with treatment naïve CLL. We enrolled eighteen participants with CLL aged 64.9 ± 9.1 years and assigned them to groups depending on distance lived from our fitness center. Ten participants (4 M/6F) completed HIIT and six participants (4 M/2F) completed a non-exercising control group (Controls). HIIT consisted of three 30-min treadmill sessions/week plus two concurrent 30-min strength training sessions/week. Physical and immunological outcomes included aerobic capacity, muscle strength and endurance, and natural killer (NK) cell recognition and killing of tumor cells. We confirmed feasibility if > 70% of HIIT participants completed > 75% of prescribed sessions and prescribed minutes, and if > 80% of high-intensity intervals were at a heart rate corresponding to at least 80% of peak aerobic capacity (VO2peak). Results are presented as Hedge’s G effect sizes (g), with 0.2, 0.5 and 0.8 representing small, medium and large effects, respectively. Following HIIT, leg strength (g = 2.52), chest strength (g = 1.15) and seated row strength (g = 3.07) were 35.4%, 56.1% and 39.5% higher than Controls, respectively, while aerobic capacity was 3.8% lower (g = 0.49) than Controls. Similarly, following HIIT, in vitro NK-cell cytolytic activity against the K562 cell line (g = 1.43), OSU-CLL cell line (g = 0.95), and autologous B-cells (g = 1.30) were 20.3%, 3.0% and 14.6% higher than Controls, respectively. Feasibility was achieved, with HIIT completing 5.0 ± 0.2 sessions/week and 99 ± 3.6% of the prescribed minutes/week at heart rates corresponding to 89 ± 2.8% of VO2peak. We demonstrate that 12-weeks of supervised HIIT combined with muscle endurance-based resistance training is feasible, and that high adherence and compliance are associated with large effects on muscle strength and immune function in older adults with treatment naïve CLL.Trial registration: NCT04950452.

High Intensity Interval

Persons with permanent atrial fibrillation experience reduced exercise tolerance, weight gain, and an associated decline in overall health. We report on a 74-year-old man with permanent atrial fibrillation who underwent a 10-week high-intensity interval training program. Substantial improvements in heart rate, blood pressure, aerobic and functional capacity, and quality of life were observed. These are desirable as these patients are not candidates for other treatment options and more effective therapies for the treatment of atrial fibrillation are needed.
