Summary
Tabata-style high-intensity interval training (T-HIIT) improved judoka endurance. Fecal succinic acid levels before training may influence T-HIIT
Area of Science:
- Sports Science
- Exercise Physiology
- Gastroenterology
Background:
- High-intensity interval training (HIIT) is a popular training method for athletes.
- Tabata-style HIIT (T-HIIT) involves short bursts of intense exercise.
- The gut microbiome, including fecal organic acids, may influence athletic performance.
Purpose of the Study:
- To evaluate the effectiveness of T-HIIT on judoka athletic performance.
- To explore the relationship between pre-training fecal organic acid profiles and performance improvements.
Main Methods:
- Twenty male judoka participated in the study.
- Physical fitness tests (Uchikomi shuttle run, jump tests, chin-ups) were conducted before and after T-HIIT.
- Fecal samples were analyzed for organic acid concentrations and stool characteristics (Bristol Stool Scale).
Main Results:
- T-HIIT significantly improved the Uchikomi shuttle run performance in all judoka.
- Improvements in other fitness tests varied among participants.
- Fecal succinic acid concentration was negatively correlated with improvements in countermovement jump and chin-ups.
- High-level competitors had higher fecal acetic and propionic acid levels and lower succinic acid levels.
Conclusions:
- T-HIIT is effective in enhancing specialized endurance for judoka.
- Modulating fecal organic acid profiles, particularly succinic acid, could potentially optimize T-HIIT's impact on athletic performance.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:24Muscle Recovery and Fatigue
2.0K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:27Exercise and Muscle Performance
1.4K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
