3. Evaluate the overall clinical utility of focal PBMT subsequent to physical training in a US Army SOF, tactical athlete population. conditions: Photobiomodulation Therapy conditions: Photomedicine conditions: Low-Level Laser Therapy conditions: Performance Enhancement conditions: Quadriceps conditions: Special Operations Readiness studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL interventionModelDescription: Approach: Special Operators attending THOR3 coach led training will be invited to participate. After consenting and screening for inclusion/exclusion, participants will be randomized into two groups: 1) sham PBMT and 2) PBMT (applied to quadriceps up to 3 times per week, post coach-led training, taking approximately 5-20 minutes each time). Baseline measurements will include body fat percentage, height, weight and military/demographic information. Metrics for counter movement jump and self-reported delayed muscle onset soreness will be taken at baseline and weekly for three weeks. Isokinetic dynamometer measurements for the lower extremities, and self-reported exertion and fatigue will be taken at baseline and at the 3-week follow-up (post three-week intervention). Oura rings will be assigned at baseline and will continuously measure sleep, heart rate, Sp02, and activity. Activity and pain will also be self-reported throughout the duration of the study. primaryPurpose: TREATMENT masking: SINGLE maskingDescription: In order to facilitate participant blinding to their randomized study group, all participants (regardless of their assigned study group) will be asked to wear blackout glasses and headphones during their treatment. whoMasked: PARTICIPANT count: 116 type: ESTIMATED name: THOR3 training + Photobiomodulation Therapy (PBMT) name: THOR3 training + sham PBMT measure: Countermovement Jump (CMJ) initial baseline: deceleration/concentric impulse measure: Countermovement Jump (CMJ) initial baseline: peak force production measure: Countermovement Jump (CMJ) initial baseline: rate of force production measure: Countermovement Jump (CMJ) initial baseline: unilateral performance comparison measure: Countermovement Jump (CMJ) week 1 follow-up: deceleration/concentric impulse measure: Countermovement Jump (CMJ) week 1 follow-up: peak force production measure: Countermovement Jump (CMJ) week 1 follow-up: rate of force production measure: Countermovement Jump (CMJ) week 1 follow-up: unilateral performance comparison measure: Countermovement Jump (CMJ) week 2 follow-up: deceleration/concentric impulse measure: Countermovement Jump (CMJ) week 2 follow-up: peak force production measure: Countermovement Jump (CMJ) week 2 follow-up: rate of force production measure: Countermovement Jump (CMJ) week 2 follow-up: unilateral performance comparison measure: Countermovement Jump (CMJ) week 3 follow-up: deceleration/concentric impulse measure: Countermovement Jump (CMJ) week 3 follow-up: peak force production measure: Countermovement Jump (CMJ) week 3 follow-up: rate of force production measure: Countermovement Jump (CMJ) week 3 follow-up: unilateral performance comparison measure: Isometric Quadriceps Strength Testing initial baseline measure: Isometric Hamstrings Strength Testing initial baseline measure: Isokinetic Quadriceps Strength Testing initial baseline measure: Isokinetic Hamstrings Strength Testing initial baseline measure: Isometric Quadriceps Strength Testing 3-week follow-up measure: Isometric Hamstrings Strength Testing 3-week follow-up measure: Isokinetic Quadriceps Strength Testing 3-week follow-up measure: Isokinetic Hamstrings Strength Testing 3-week follow-up measure: Defense and Veteran's Pain Rating Scale (DVPRS) initial baseline measure: Defense and Veteran's Pain Rating Scale (DVPRS) daily reports measure: Visual Analog Scale (VAS) initial baseline measure: Visual Analog Scale (VAS) week 1 follow-up measure: Visual Analog Scale (VAS) week 2 follow-up measure: Visual Analog Scale (VAS) week 3 follow-up measure: Borg Modified Rating of Perceived Exertion (RPE) initial baseline measure: Borg Modified Rating of Perceived Exertion (RPE) 3-week follow-up measure: Elloumi fatigue scale initial baseline measure: Elloumi fatigue scale 3-week follow-up measure: Quick Physical Activity Rating scale (QPAR) measure: Oura Ring Sleep Data: sleep metrics - sleep duration measure: Oura Ring Sleep Data: sleep metrics - time in bed measure: Oura Ring Sleep Data: sleep metrics - light sleep length measure: Oura Ring Sleep Data: sleep metrics - rapid eye movement (REM) sleep length measure: Oura Ring Sleep Data: sleep metrics - deep sleep length measure: Oura Ring Sleep Data: sleep metrics - sleep latency measure: Oura Ring Sleep Data: sleep metrics - sleep efficiency score measure: Oura Ring Sleep Data: sleep metrics - sleep quality score measure: Oura Ring Sleep Data: Readiness trends - body temperature changes measure: Oura Ring Sleep Data: Readiness trends - heart rate changes measure: Oura Ring Sleep Data: Readiness trends - heart rate variability (HRV) measure: Oura Ring Sleep Data: Readiness trends - respiration rate measure: Oura Ring Sleep Data: Readiness trends - blood oxygen saturation measure: Oura Ring Sleep Data: Readiness trends - sleep regularity measure: Oura Ring Sleep Data: Readiness trends - readiness score measure: Body Measurements: Height (cm) measure: Body Measurements: Weight (kg/lbs) measure: Body Measurements: Body composition (% body fat) measure: Body Measurements: C1 - proximal thigh circumference (cm) measure: Body Measurements: C2 - distal thigh circumference (cm) measure: Body Measurements: L1 - length of thigh (cm) sex: MALE minimumAge: 18 Years maximumAge: 45 Years stdAges: ADULT typeAbbrev: Prot_SAP hasProtocol: True hasSap: True hasIcf: False label: Study Protocol and Statistical Analysis Plan date: 2024-03-20 uploadDate: 2024-03-29T15:19 filename: Prot_SAP_000.pdf size: 435470 typeAbbrev: ICF hasProtocol: False hasSap: False hasIcf: True label: Informed Consent Form date: 2024-03-19 uploadDate: 2024-03-29T15:20 filename: ICF_001.pdf size: 165533 hasResults: False
