About this study

Official title: Effects of Photobiomodulation Therapy on Physical Performance in Female Futsal Athletes

The aim of this study is to investigate the effects of photobiomodulation therapy (PBMT) on physical performance in female futsal athletes. It is hypothesized that PBMT is superior to placebo condition in improving the ability to perform repeated sprints and aerobic capacity in high-intensity, intermittent activity (i.e., Bangsbo sprint test and yoyo intermittent recovery level-1, respectively).

Read the detailed description

The aim of this project is to investigate the effects of photobiomodulation therapy (PBMT) on physical performance and muscle recovery in female futsal athletes. A crossover experimental studies will be conducted with 15 female futsal athletes. Participants will receive PBMT or placebo 10 minutes before the Bangsbo sprint test (BST) and Yo-Yo Intermittent Recovery Test (YYIR1) at two time points (M1 and M2), separated by a 2-week washout period. PBMT will be applied according to the randomization order at M1 and M2, so that the participant who receives active PBMT at M1 will receive placebo PBMT at M2, and vice versa. The following variables will be analyzed in the BST: (1) Total Time (TT): the sum of the time of all sprints, and Fatigue Index (FI): the difference between the worst and best times. For the yo-yo test, the total distance covered will be analyzed as an indicator of aerobic performance. In addition, the rating of perceived exertion (RPE) will be recorded immediately after the Bangsbo sprint test and after the yo-yo test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Physical performance in the Bangsbo Sprint Test

    The ability to perform repeated sprints with changes of direction will be assessed using the Bangsbo sprint test (BST). The test consists of seven sprints of 34.2 meters between the starting cone (A) and the finishing cone (E), interspersed with a 25-second active recovery period. During recovery, participants perform a light jog back to the starting point (cone A). The change of direction (right or left) between cones B and C in the first sprint is determined by each participant's individual preference, and subsequent sprints are performed alternately between the right and left sides. Participants will be verbally encouraged to perform their best in all sprints. The following variables were analyzed: total time (sum of all sprints), and fatigue index (FI) = 100 - (average time/best time) x 100). The BST is considered valid and reliable for analyzing aerobic recovery capacity.

    Measured: Baseline (M1) and after 2 weeks (M2)

  2. Performance in Yoyo intermittent recovery level 1

    Aerobic recovery capacity in high-intensity intermittent running will be assessed using the yo-yo intermittent recovery test level 1 (YYIR1). The protocol consists of 40-meter runs (stages) between cones B and C (20 m out + 20 m back) followed by 10 seconds of active recovery between cones A and B (walking a 5 m path). The initial speed of the test is 10 km/h, with a progressive increase in speed by auditory stimulus (beeps) (the time between "beeps" decreases at each stage, forcing the athlete to run faster). The test is terminated when the participant does not reach the marking line (cone B) within the stipulated time in two attempts (even if not consecutive) or is unable to continue the test due to fatigue/exhaustion (6). Participants are verbally encouraged to perform as well as possible during the test. The total distance covered (in meters) will be used as a variable for aerobic performance. The YYIR1 test is considered valid and reliable for analyzing aerobic recovery capacity.

    Measured: Baseline (M1) and after 2 weeks (M2)

Secondary outcomes (1)

  1. Rating of perceived exertion

    The rating fo percevied exertion (RPE) will be recorded immediately after the Bangsbo and YYIR1 tests, using the Borg 6-20 scale. The scale contains 15 points ranging from 6 "no effort" to 20 "maximum effort", and the participant indicate a number on the scale that represent their perceived exertion at that moment. RPE is a simple, valid and reliable instrument for assessing perceived exertion in running tests. All participants will be previously familiarized with the scale through the cognitive anchoring procedure.

    Measured: Baseline (M1) and after 2 weeks (M2)
