|
Jiu-Jitsu Anaerobic Performance Test Total Valid Repetitions
Tijdsspanne: At Visit 2 or Visit 3, within 6 days after Visit 1
|
Total number of valid butterfly-guard lifting repetitions completed across five 60-second work bouts separated by 45 seconds of passive recovery.
Higher values indicate better BJJ-specific anaerobic performance.

At Visit 2 or Visit 3, within 6 days after Visit 1

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Maximal Inspiratory Pressure
Tijdsspanne: At Visit 1
|
The highest acceptable maximal inspiratory pressure meeting prespecified reproducibility criteria, recorded in centimeters of water (cmH2O).
Higher values indicate greater inspiratory muscle strength.
|
At Visit 1
|
|
Maximal Expiratory Pressure
Tijdsspanne: At Visit 1
|
The highest acceptable maximal expiratory pressure meeting prespecified reproducibility criteria, recorded in centimeters of water (cmH2O).
Higher values indicate greater expiratory muscle strength.
|
At Visit 1
|
|
Maximum Static Kimono Grip Test Time
Tijdsspanne: At Visit 2 or Visit 3, within 6 days after Visit 1
|
Maximum time, in seconds, that the participant maintains a suspended position with maximal elbow flexion while gripping a kimono wrapped around a horizontal bar.
Higher values indicate greater static kimono grip endurance.
|
At Visit 2 or Visit 3, within 6 days after Visit 1
|
|
Forced Vital Capacity (FVC)
Tijdsspanne: At Visit 1
|
Forced vital capacity measured by spirometry and recorded in liters (L).
Percent-predicted and z-score values will also be documented when available.
Higher values generally indicate greater ventilatory volume, with interpretation based on appropriate reference limits.
|
At Visit 1
|
|
Forced Expiratory Volume in 1 Second (FEV1)
Tijdsspanne: At Visit 1
|
Forced expiratory volume in the first second measured by spirometry and recorded in liters (L).
Percent-predicted and z-score values will also be documented when available.
Higher values generally indicate greater expiratory volume in the first second, interpreted using appropriate reference limits.
|
At Visit 1
|
|
FEV1/FVC Ratio
Tijdsspanne: At Visit 1
|
Ratio of forced expiratory volume in the first second to forced vital capacity, calculated from acceptable spirometry maneuvers and recorded as a ratio and percentage.
The z-score and lower limit of normal will be documented when available; lower values may indicate airflow limitation.
|
At Visit 1
|
|
Peak Expiratory Flow (PEF)
Tijdsspanne: At Visit 1
|
Peak expiratory flow obtained during acceptable forced spirometry maneuvers and recorded in liters per second (L/s).
The highest acceptable value will be recorded.
Higher values indicate greater maximal expiratory flow.
|
At Visit 1
