Trial summary

This study aims to investigate the effects of whole-body photobiomodulation on professional soccer players during a state championship. The primary question is whether photobiomodulation improves recovery, reduces muscle fatigue, and enhances performance compared to standard training without photobiomodulation.

The primary question is whether photobiomodulation improves recovery, reduces muscle fatigue, and enhances performance compared to standard training without photobiomodulation.

Read the detailed description

Detailed Description:

This randomized, controlled clinical trial aims to evaluate the effects of whole-body photobiomodulation (PBM) on recovery and performance in professional soccer players during a state championship.

The intervention will be performed twice weekly on non-consecutive days for 8 weeks, in combination with each athlete's standard training routine. Participants will be allocated to either an active PBM group or a sham PBM group, both following identical procedures to maintain blinding.

Throughout the study, participants will complete scheduled assessments at baseline, during, and after the 8-week period to monitor performance, muscle soreness, and hematological responses. Data will be analyzed using appropriate statistical tests, with a significance level of 5% (two-tailed).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Whole-Body Photobiomodulation (PBM) (Active PBM)Radiation

    This intervention consists of whole-body photobiomodulation delivered using a full-body PBM device. Sessions are performed twice weekly on non-consecutive days for 8 weeks, coinciding with the athletes' standard training. The device emits therapeutic light at specified wavelengths and power, targeting the entire body. The protocol is standardized according to prior research, ensuring consistent exposure for all participants in the active arm. The intervention aims to improve muscle performance and recovery while reducing delayed onset muscle soreness (DOMS).

  • Sham PBMRadiation

    Intervention Description (Sham PBM):

    Participants receive a sham photobiomodulation intervention using the same device and schedule, but without emission of therapeutic light. The procedure mimics the active intervention to maintain blinding while allowing comparison of outcomes, including muscle performance, DOMS, and blood markers.

Study groups in NCT07224646
Study groupRoleWhat they receive
Active PBMExperimentalWhole-body PBM delivered with a Joovv Elite System (6 LED panels; 660±10 nm red and 850±10 nm near-infrared; total panel area ≈12,193 cm²). Athlete stands ~20 cm from panels, wearing eye protection. Two exposures per session: 450 s anterior + 450 s posterior (total 15 min). Measured average irradiance ≈81.62 mW/cm² and energy density per region ≈25.71 J/cm² at 20 cm. Two sessions/week on non-consecutive days for 8 weeks, after routine training.

What is being measured

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

  1. Delayed Onset Muscle Soreness (DOMS)

    Pain intensity measured using the Numeric Rating Scale (NRS; 0-10 points; higher scores = worse pain) during a maximal voluntary knee-extension contraction in sitting. Pain location/extent captured with a standardized pain drawing (exploratory). Primary analysis uses NRS.

    Measured: Baseline (T1), weekly (T2, weeks 1-8), and end of week 8 (T3).

Secondary outcomes (3)
  1. Knee Extensor Strength (Hand-Held Dynamometry)

    Peak force of dominant-leg knee extensors measured with a handheld dynamometer in standardized seated position; mean of two MVC attempts used for analysis.

    Measured: Baseline (T1), weekly (T2, weeks 1-8), end of week 8 (T3)

  2. Squat Jump (SJ) Height

    Vertical jump height (cm) from Squat Jump (SJ) with hands on hips; mean of two trials; flight-time method on contact device.

    Measured: Baseline (T1), weekly (T2, weeks 1-8), end of week 8 (T3) Unit: cm

  3. Countermovement Jump (CMJ) Height

    Vertical jump height (cm) from Countermovement Jump (CMJ) with hands on hips; mean of two trials; flight-time method on contact device.

    Measured: Baseline (T1), weekly (T2, weeks 1-8), end of week 8 (T3)

Model description
Model Description: Participants are randomly assigned to two parallel groups: an Active Photobiomodulation (PBM) group and a Sham PBM group. Both groups undergo the same training schedule and assessment timeline, but only the active group receives therapeutic light exposure. There is no crossover between groups throughout the 8-week intervention period.
