Low-Volume High-Intensity Interval Training Versus Moderate-Intensity Continuous Training on Body Composition, Cardiometabolic Profile, and Physical Capacity in Older Women

Abstract

Objectives: To compare the effect of low-volume high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) on fat mass, cardiometabolic profile, and physical capacity, and confirm its feasibility in older women. Methods: Inactive older women (60–75 years) were randomly assigned to 8 weeks of either HIIT (75 min/week; n = 9) or MICT (150 min/week; n = 9). Body composition, fasting metabolic profile, cardiovascular risk (Framingham score), and physical capacity (senior fitness test, peak oxygen uptake) were assessed before and after the intervention. Feasibility was evaluated with completion rate (training compliance; dropout rate) and affective response (Feeling Scale; pre- and postexercise). Results: Total cholesterol level, non-high-density lipoprotein cholesterol level, and the Framingham risk score decreased in both groups (ps ≤ .03). Although peak oxygen uptake remained unchanged, the 6-min walk test distance increased (p < .0001), irrespective of the group. Completion rate and affective responses were not different between groups (ps ≥ .38). Conclusion: A short-term HIIT program is feasible and provides as much benefits as MICT in older women.

Effects of high vs moderate-intensity intermittent training on functionality, resting heart rate and blood pressure of elderly women

“…These results contradict our hypothesis because we expected that the higher velocities achieved in the HIIT condition would promote greater increases in gait velocity due to specificity and following previous findings [42]. On the other hand, our data is not without support, since there is evidence in which the performance of HIIT or MICT promoted functional performance gains, but without differences between the types of training [43][44][45]. Considering the characteristics of the participants, these functional gains are very important, since they can decrease the risk of mortality, in which higher levels of functional capacity are related to lower risk of falls and mortality [46,47].…”

High-Intensity Interval Circuit Training Versus Moderate-Intensity Continuous Training on Cardiorespiratory Fitness in Middle-Aged and Older Women: A Randomized Controlled Trial

“…Therefore, there seems to be a greater trend for VO 2max -ES improvement in HIIT than in MICT. Our results are in accordance with various studies showing that the application of both HIICT and MICT succeeded in increasing the VO 2max values for subjects with cardiovascular diseases [4,24], as well as in healthy elderly and middle-aged people [38]. Similarly, in line with the better trend shown by HIICT, a meta-analysis showed that HIIT improved VO 2max more than MICT in overweight or obese adults [39].…”

Effect of High-Intensity Interval Training with Eryngium Campestre on Lipid Profile and Glycemic Indices in High-Fat Diet-Induced Obese Rats

“…They reviewed the effects of 12 weeks' HIIT on the serum lipid profile of patients with dyslipidemia and concluded that HIIT could be used as an intervention method to regulate the serum lipids of dyslipidemia patients (17). Also, the findings of the present study are in line with the findings by Boukabous et al (18). They reported that two types of training, including HIIT and moderate-intensity continuous training (MICT) improved lipid profile and fasting blood glucose in older women (18).…”

In addition to exercise activities, nutritional therapy is an essential part of treatment for people with high blood lipids.…”
