MedicalResearch.com: What is the background for this study?
Response: High-intensity interval training (HIIT) involves multiple brief, high-intensity efforts, separated by periods of recovery. Research shows that several weeks of HIIT can elicit meaningful physical health benefits that are similar to those of traditional, long-duration aerobic exercise. While HIIT is time-efficient and can induce important health benefits, one major drawback is that people may find it to be unpleasant – especially those who are insufficiently active and not meeting recommended physical activity guidelines. The potentially unpleasant nature of HIIT may deter people from beginning or adhering to a HIIT program.
Consequently, researchers have begun to investigate the use of music as a potential strategy to enhance people’s pleasure during HIIT. However, the current research evidence is quite limited and, in particular, insufficiently active individuals have been understudied.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Injurious falls among community-dwelling older adults are a serious public health and cost-bearing problem worldwide.Exercise has been shown to reduce falls and injurious falls among older adults. However, evidence is limited with regard to the type of exercise interventions that are most effective, without exacerbating the risk in some individuals, in reducing injurious falls.
This study addresses this knowledge gap in the field of falls prevention. Findings from this study showed that a six-month Tai Ji Quan program reduced the incidence of injurious falls among frail elderly by 53% compared to a regular (multimodal) exercise intervention. The effect of the Tai Ji Quan intervention was shown to be robust, and still evident at follow-up examinations six months after the study.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Although being overweight and/or obese are associated with numerous health risks, the prevalence of both are continuing to increase worldwide. The treatment would include anything that results in an increase in energy expenditure (exercise) or a decrease in energy intake (diet). However, our metabolism seems to adapt to variations in physical activity to maintain total energy expenditure. Although lower-than-expected weight loss is often attributed to incomplete adherence to prescribed interventions, there are other factors that might influence the results, such as, metabolic downregulation.
So, instead of making people spend more calories, maybe we have to think on how to promote metabolic changes in order to overcome these physiological adaptations above-mentioned. In this regard, high intensity training might be particularly interesting as a strategy to promote fat loss. Irrespective the amount of calories spent during training, higher intensity exercise seems to promote many physiological changes that might favor long-term weight loss. For example, previous studies have shown that interval training is able to promote upregulation of important enzymes associated with glycolysis and beta oxidation pathways, which occurs in a greater extent than with moderate intensity continuous exercise.
Our findings suggest that interval training might be an important tool to promote weigh loss. However, I t might be performed adequately and under direct supervision in order to get better results.
