Study summary

Known as "Thai boxing," Muay Thai utilizes a combination of upper limb strikes (such as punches and elbow strikes) as well as lower limb strikes (such as kicks and knee strikes), and is thus referred to as the "art of eight limbs." It is practiced worldwide and is a prominent discipline in many mixed martial arts (MMA) training camps. In this sport, training load control involves monitoring and adjusting the quantity and intensity of training according to each athlete's capacity. In the context of combat sports, such as Muay Thai, heart rate variability (HRV) and assessment of body composition by bioelectrical impedance analysis can be used as tools to evaluate training responses. Additionally, HRV can also serve as a tool for assessing recovery after training or competition. If HRV does not return to baseline after training or competition, it may be a sign that the athlete is not fully recovered and may need more time to recuperate before returning to training or competition. Due to the absence of studies in the literature that have assessed a possible association between HRV and dehydration and rehydration processes in amateur Muay Thai athletes, it becomes essential to evaluate this correlation. Given the growing interest in practicing Muay Thai in gyms, assessing the sympathetic-vagal balance, body composition, and performance of these athletes becomes of utmost importance. Therefore, the aim of this study is to investigate the relationship between dehydration indicators, HRV parameters, and performance in the frequency speed kick test (FSKT). Participants will be assessed before and after an eight-week training program, conducted three times a week. Assessments will include resting HRV measurement and FSKT; in addition, bioimpedance will be used to estimate the body composition of participants pre- and post-training. It is expected that the results will reveal changes in HRV, performance, and body composition of the athletes after training.

Study arms

  • Experimental
    Group Exercise

    30 functional specific exercises for muaythai athletes. Nutrition Control HRV quantify.

    Other: Specifical Functional Training Exercises

Interventions

  • OtherSpecifical Functional Training Exercises

    Strength Training: Include compound exercises like squats, deadlifts, lunges, and bench presses to build overall strength and muscle mass. Focus on functional movements that mimic the actions used in Muay Thai. Core Stability Exercises: A strong core is essential for generating power and maintaining balance during strikes and defensive maneuvers. Plyometric Training: Jumping exercises such as box jumps, squat jumps, and split jumps help improve explosive power and enhance muscular endurance, crucial for delivering swift and powerful strikes. Flexibility and Mobility Training: Incorporate stretching exercises to improve flexibility, joint range of motion, and prevent injuries. Interval Training: Perform high-intensity interval training (HIIT) sessions that combine cardiovascular exercises.

What researchers measure

Primary outcomes

  1. HRV during specifical physical test

    Measurement of HRV obtained during the FSKT protocol, pre and post-training of 8 weeks specific conditioning and strength for Muay Thai and nutritional intervention.

    Time frame: 1 year

Secondary outcomes

  1. Correlation with BIA analysis, HRV and Specific Physical Test

    Based on the results obtained through the Bioelectrical Impedance Analysis (BIA) test, the existence of potentially significant correlations between these measurements and the activity of the autonomic nervous system, specifically sympathetic-vagal regulation, is being investigated, assessed through analysis of Heart Rate Variability (HRV).

    Time frame: 1 year

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Mar 2024; primary completion for Jun 2025, 15 months later.

Of 167 non-industry interventional studies with no phase under Nervous System Diseases, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 57. This study's planned 15 months is below that.

Counting every sponsor, half of 193 studies reached it within 30 months; a quarter within 11 and three quarters within 57.

Nervous System Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
