The aim of present study was to compare blood lipid postprandial profile response in two modes of high-intensity intermittent exercise. Twelve individuals (6 men and 6 women) were submitted to a maximal incremental test (to determine maximal aerobic power [MAP] and V. O [peak oxygen uptake]), high-intensity intermittent all-out exercise (60×8-sec bouts interspersed by 12-sec passive recovery) and fixed high-intensity intermittent exercise (100% maximal aerobic speed, consisted of 1-min repetitions at MAP [70 rpm] separated by 1-min of passive recovery). Blood samples were collected pre, immediately, 45 and 90-min postexercise. Serum was analyzed for total cholesterol and its ratio, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), very low-density lipoprotein (VLDL) cholesterol, and triacylglycerol (TAG). For TAG there was a main effect of moment with higher values immediately postexercise compared to 45-min postexercise. For VLDL there was a main effect to moment with higher values immediately post exercise than pre and 45-min postexercise; higher values 90-min postexercise than 45-min postexercise. There was no effect for HDL-c, LDL-c, and cholesterol. For area under the curve there was no difference for any variable. Our results indicated that both kinds of acute exercise session lead to no improvement in the acute response of serum lipid profile of healthy young.

The Multiple Frequency Speed of Kick Test (FSKT) is used to investigate which characteristics are necessary for, contribute to, or limit the ability to repeat high-intensity intermittent efforts in taekwondo. This cross-sectional study investigated the relationship between anthropometric and body composition characteristics, muscle power performance, and sport-specific anaerobic performance. Nineteen black belt taekwondo athletes (mean ± SD age: 17.

However, there is limited understanding of how an individual's initial physical fitness level might influence the extent of adaptations achieved through these programs. This study aimed to compare the impacts of SSG and HIIT on male soccer players, while also considering the players' athleticism, categorized into lower and higher total athleticism score (TSA).

Article Synopsis
- Tabata training started as a specific high-intensity cycling workout for athletes, involving short bursts of effort followed by brief recovery periods.
- It has evolved over 30 years, adapting to various forms of exercise like resistance training and being applied in different sports contexts.
- The article reviews physiological adaptations from Tabata training and its use during the COVID-19 pandemic to combat inactivity, illustrating its broad applicability for both performance and health improvements.
The Effect of Eight Weeks of High-Intensity Interval Training on Follistatin Gene Expression in the Fast and Slow Twitch Muscles of Rats with Myocardial Infarction.

Article Synopsis
- Myocardial infarction leads to mitochondrial damage and loss of function, prompting research into treatment options, including high-intensity interval training (HIIT) for muscle recovery.
- A study at Shahid Rajaei University investigated the impact of 8 weeks of HIIT on follistatin (FST) gene expression in fast and slow twitch muscle in rats with myocardial infarction.
- Results showed a significant decrease in FST gene expression in slow twitch muscles and a significant increase in fast twitch muscles after HIIT, indicating changes in muscle atrophy response following intense exercise.
Effect of high-intensity intermittent rehabilitation training on physical function, gut microbiome and metabolite after percutaneous coronary intervention in patients with coronary heart disease.

Background: Postoperative rehabilitation exercise training after percutaneous coronary intervention (PCI) is crucial for coronary heart disease (CHD) patients in restoring health and preventing recurrence, including high-intensity interval training (HIIT). However, the impact of HIIT on cardiopulmonary function, gut microbiome and metabolite remains underexplored.
Methods: This study included 60 patients with CHD who underwent percutaneous coronary intervention (PCI).
