Effects of High Intensity Interval Training on Health Related Fitness and Bone Mineral Density in Middle School Girls

Introduction: High-intensity interval training (HIIT) can promote improvement in health and physical conditioning and contribute to the increase in cardiorespiratory capacity (VO2max), local muscular endurance, and improved body composition. However, its effects on health-related physical fitness in children and adolescents are still unclear. Objective: The objective of the study was to analyze the effectiveness of HIIT in the health-related physical fitness of children and adolescents. Methods: The present study analyzed articles from databases (SPORTDiscus, Web of Science, Medline via Pubmed, Scopus, Scielo, and Bireme). The PICO strategy was applied to select articles and CONSORT to assess the quality of randomized controlled trials. 511 studies were found. Of this total, 101 articles were eligible for analysis of the abstract. Results: At the end of the selection process, 10 articles resulted in the inclusion criteria. The results suggest that among the variables analyzed by the articles referring to health-related physical fitness, HIIT demonstrated effectiveness in VO2max, body mass index (BMI), and percentage of fat (%F) in this population. Conclusion: However, it was not possible to state that HITT promoted adjustments in flexibility, strength and local muscular endurance, and further studies are needed to assess its effects on health-related physical fitness.Keywords: physical exercise, adolescent, primary health care.

High Intensity Interval

AbstractThe effects of high intensity interval training (HIIT) frequency on cardiometabolic health and quality of life were examined in 35 healthy inactive adults (age: 31.7±2.6 yrs, VO2peak: 32.7±7.4 ml·kg−1 ·min−1). Participants were randomly assigned to a control (CON) and two training groups, which performed 10×60-s cycling at ~83% of peak power, two (HIIT-2) or three times per week (HIIT-3) for eight weeks. Compared with CON, both training regimes resulted in similar improvements in VO2peak (HIIT-2: 10.8%, p=0.048, HIIT-3: 13.6%, p=0.017), waist circumference (HIIT-2: -1.4 cm, p=0.048, HIIT-3: -2.4 cm, p=0.028), thigh cross-sectional area (HIIT-2: 11.4 cm2, p=0.001, HIIT-3: 9.3 cm2, p=0.001) and the physical health component of quality of life (HIIT-2: 8.4, p=0.001, HIIT-3: 12.2, p=0.001). However, HIIT-3 conferred additional health-related benefits by reducing total body and trunk fat percentage (p<0.05, compared with CON), total cholesterol and low-density lipoprotein-cholesterol (p<0.02, compared with CON) and by improving the mental component of quality of life (p=0.045, compared with CON). In conclusion, performing HIIT only twice per week is effective in promoting cardiometabolic health-related adaptations and quality of life in inactive adults. However, higher HIIT frequency is required for an effect on fat deposits, cholesterol and mental component of well-being.

Purpose: The purpose of this study was to evaluate the limited efficacy of a high-intensity interval training (HIIT)-based fitness education unit in middle school physical education (PE). Method: The study took place in six PE classes at one middle school located in the southern United States. The authors conveniently assigned the classes to treatment (n = 3 classes; 113 students) or control (n = 3 classes; 119 students) groups. Two trained PE specialists implemented the HIIT lessons two to three times per week for 8 weeks. The authors collected mixed methods data at the student, class, and teacher levels for the evaluation. Results: The focus group teacher interview with the teachers, field observations, and accelerometer-determined in-class physical activity data revealed sound implementation fidelity. The HIIT-based fitness education condition also showed greater improvement in physical activity and fitness knowledge and attenuated decline in curl-up scores compared with the control. Conclusion: The findings support the limited efficacy of implementing HIIT for fitness education in middle school PE programs.

High Intensity Interval

High-intensity interval training (HIIT) is promoted as a time-efficient strategy to improve body composition but concomitant beer intake, which is common among physically active individuals, may interfere with these effects. The primary aim of this study is to determine the effects of a 10-week (2 days/week) HIIT program on anthropometric and body composition measurements, and to assess whether those effects are influenced by the moderate consumption of beer (at least 5 days/week), or its alcohol equivalent. Young (24 ± 6 years old) healthy adults (n = 72, 35 females) volunteered for a non-training group (Non-Training group) or for HIIT training. Those going for training choose whether they preferred to receive alcohol or not. Those choosing alcohol were randomly allocated for receiving beer (5.4%; T-Beer group) or the equivalent amount of alcohol (vodka; T-Ethanol group) in sparkling water. Those choosing no-alcohol were randomly allocated for receiving alcohol-free beer (0.0%; T-0.0Beer group) or sparkling water (T-Water group). From Monday through Friday, men ingested 330 mL of the beverage with lunch and 330 mL with dinner; women ingested 330 mL with dinner. Before and after the intervention, anthropometry and body composition, through dual-emission X-ray absorptiometry, were measured. No changes in body mass, waist circumference, waist/hip ratio, visceral adipose tissue or bone mineral density occurred in any of the groups. By contrast, in all the training groups, significant decreases in fat mass together with increases in lean mass (all p < 0.05) occurred. These positive effects were not influenced by the regular intake of beer or alcohol. In conclusion, a moderate beer intake does not blunt the positive effect of 10-week HIIT on body composition in young healthy adults.

The Impact

Abstract Purpose To evaluate the impact of high-intensity interval training (HIIT) on health-related outcome parameters in the prehabilitation of patients diagnosed with cancer. Methods A systematic review and meta-analysis of comparative studies on HIIT in cancer prehabilitation conducted by screening standard databases from their inception to March 30, 2020. Outcomes of interest included cardiorespiratory fitness, feasibility, safety, clinical, and patient-reported outcomes. Results Of the 855 identified studies, 8 articles met the inclusion criteria (7 randomized, 1 non-randomized controlled trial) with a total of 896 patients. The study protocols were heterogeneous, but the methodological quality ranged from good to high according to PEDro scale. Meta-analysis revealed a significant improvement of peak oxygen consumption (VO2peak) achieved with HIIT compared to usual care. Furthermore, HIIT was feasible and safe, showing low risk of adverse events and positive effects on health-related outcomes in prehabilitative settings. Conclusion In the phase of prehabilitation, HIIT has potential health benefits in patients diagnosed with cancer and is feasible and safe to perform. Nonetheless, larger randomized controlled trials focusing on long-term effects (such as cancer recurrence or survival rates) are missing, to underline the potential relevance of HIIT for cancer patients.
