Effects of a 10-Week High-Intensity Interval Training Programme on Biochemical and Hormonal Responses in Elite Female Futsal Players
19 de agosto de 2026 atualizado por: Shimal Hamza Hamad, Soran University
Temporal Dynamics of Biochemical and Hormonal Responses to Interval Training in Elite Female Futsal Players: A 10-Week Longitudinal Analysis Across Menstrual Cycle Phases
This study aims to investigate the biochemical, hormonal, and physiological adaptations to a 10-week periodized high-intensity interval training (HIIT) programme in elite female futsal players.
The study will examine changes in aerobic fitness, blood lactate kinetics, muscle damage biomarkers, inflammatory markers, and reproductive hormones throughout the intervention.
In addition, the influence of menstrual cycle phases on these physiological responses will be evaluated to improve understanding of sex-specific training adaptations and recovery.
The findings are expected to contribute to evidence-based, individualized training and recovery strategies for female futsal athletes.

Descrição detalhada
Female futsal is a high-intensity intermittent team sport requiring substantial aerobic and anaerobic fitness.
Despite increasing participation of women in competitive sports, limited evidence exists regarding the biochemical and hormonal adaptations to structured interval training, particularly across different menstrual cycle phases.
This prospective longitudinal study will recruit 32 elite female futsal players who will participate in a supervised 10-week periodized HIIT programme consisting of lactate threshold training, anaerobic intensification, and sport-specific interval training.
Physiological assessments will include VO₂max, lactate threshold, blood lactate kinetics, creatine kinase, interleukin-6, C-reactive protein, cortisol, and reproductive hormones.
Menstrual cycle phases will be monitored using validated menstrual tracking methods and hormonal confirmation.
Outcomes will be assessed repeatedly throughout the intervention to determine temporal adaptations and the influence of menstrual cycle phase on training responses and recovery.
The results are expected to support individualized, evidence-based training prescription for female athletes.

Mean Change from Baseline in Lactate Threshold Velocity
Prazo: Baseline and Week 10
|
Lactate threshold velocity determined during incremental exercise testing.
Lactate threshold velocity is defined as the running velocity corresponding to the lactate threshold.
Unit of measure: km/h.
Higher values indicate improved aerobic endurance.

|
Mean Change from Baseline in Resting Blood Lactate Concentration
Prazo: Baseline and Week 10
|
Resting blood lactate concentration measured from venous blood samples collected under standardized resting conditions before exercise.
Unit of Measure: mmol/L.

|
Mean Change from Baseline in Lactate Clearance Rate
Prazo: Baseline and Week 10
|
Lactate clearance rate calculated as the rate of decline in blood lactate concentration from serial post-exercise measurements obtained during standardized recovery.
The calculated clearance rate is reported as one value in mmol/L/min.
