Red Light Therapy for Increasing Strength
There’s a reason so many professional trainers are incorporating red light therapy for themselves and their clients. As the graphic below shows, there’s been a wide range of clinical research showing major strength gains when people add red light therapy to their exercise routine. Everything from more reps, stronger legs, greater max torque, and stronger grip.
Red Light Therapy Increases Strength
There’s a reason so many professional strength trainers are incorporating red light therapy into their routines.
Stronger Strength Training: Researchers from a 2016 trial concluded: “The application of phototherapy yields enhanced strength gains when it is applied before exercise."*
Stronger Legs: In a 2011 study, researchers stated the men receiving light therapy were “the only group to show an increase in muscle performance in the isokinetic dynamometry test compared with baseline.”**
Stronger Grip: A placebo-controlled 2014 study found that red light therapy treatments significantly increased maximum repetitions of hand and grip exercises by 52%, as measured by an isokinetic dynamometer.***

Enhanced Muscle Growth and Size with Red Light Therapy
Red light therapy promotes significant strength and athletic performance gains, and it’s also a game changer for muscle growth.
Research published in the American Journal of Physical Medicine and Rehabilitation found light therapy promotes the growth of healthy muscle tissue, or muscle hypertrophy, naturally increasing muscle size and bulk—as well as strength. [1,2]
A separate study in the European Journal of Applied Physiology compared muscle growth and strength between two groups of athletes—one using light therapy combined with exercise, the other using exercise alone—and found that muscle thickness and strength were significantly improved (by over 50%) in those who used light therapy. 
Increasing Running Speed with Red Light Therapy
Red light therapy improves running performance too. A 2018 study tested male running performance in 3 groups: men receiving red light therapy treatments, a placebo group, and a control group. The highest performers were easily the light therapy group, which saw “significantly improved running economy, rate of perceived exertion, velocity, peak of velocity, and total time to exhaustion, compared with placebo.” 
Even elite athletes see big speed gains with red light therapy. Pro rugby players were tested in 2016, and the results showed light treatments led to faster running, including “significantly improved the average time of sprints.” 
Improving Endurance and Stamina with Red Light Therapy
Red light therapy is helping people work out longer, with less of an oxygen deficit to overcome. This has been shown on treadmills, bikes, and training fields across the world. The graphic below highlights some of the major research showing endurance gains for athletes.
Better Endurance with Red Light Therapy
Numerous recent studies show red light therapy helps people workout longer, with less of an O2 deficit, whether it’s on the treadmill, bike, or training field.
Treadmill Training: Researchers from a triple-blind, placebo-controlled trial published in 2018 found that pre-exercise light therapy can “increase the time-to-exhaustion and oxygen uptake and also decrease the body fat in healthy volunteers when compared to placebo.”*
3-Times Faster Endurance Improvements: Researchers from that same 2018 study concluded that light therapy treatments “applied before and after endurance-training exercise sessions lead to improvement of endurance three times faster than exercise only.”*
Light Therapy for Cycling Performance: Researchers from another 2018 clinical study found that red light therapy “increased time to exhaustion in competitive cyclists, suggesting this intervention as a possible non-pharmacological ergogenic agent in cycling.”**

**Lanferdini FJ, Bini RR, et al. Improvement of Performance and Reduction of Fatigue With Low-Level Laser Therapy in Competitive Cyclists. International Journal of Sports Physiology and Performance. 2018 Jan 1;13(1):14-22.
And that’s just a small sampling. Pro soccer players have been studied in clinical settings, with researchers concluding that light therapy “significantly increased the time of staying on the pitch and had a significant improvement in all the biochemical markers evaluated...pre-exercise therapy can enhance performance and accelerate recovery of high-level players.” 
Women of All Ages Train & Perform Better with Red Light Therapy
Several of the studies mentioned so far analyzed the physical performance of male athletes, but the clinical research is just as positive for women of all ages and fitness levels, as the graphic below highlights.
Women of All Ages Perform Better with Red Light Therapy
Published research shows red light therapy is highly effective for women looking to improve their physical performance and recover faster from workouts and strain.
Improved Exercise & Muscle Recovery for Postmenopausal Women: In 2013, researchers analyzed the exercise tolerance and muscle recovery of postmenopausal women and found that ight therapy and training “can improve maximal performance and post-exercise recovery.”*
Women 18-30 Stronger with Red Light Therapy: In 2014, Brazilian doctors conducted a double-blind, controlled trial of healthy women and concluded that red light therapy “increased muscle torque at the beginning of the exercise and maintained the levels of lactate after resistance exercise.”**
Women 50-60 Stronger with Red Light Therapy: A 2014 study evaluated women in their 50s and found “significantly higher values of [quadricep] power and total work for the LED group.”***

Dr. Sarah Ballantyne, aka Paleo Mom, studied the clinical research on red light therapy, gave Joovv a try, and saw a big difference in her workout performance and muscle recovery. Dr. Sarah says:
Amelia Boone is one of the most decorated endurance and obstacle racers of all-time. She tried Joovv red light therapy for rehab after spraining ligaments in her forefoot. Amelia says Joovv made a huge difference and is absolutely clutch for muscle recovery and rehab.
Red Light Therapy Prevents Muscle Soreness and Fatigue
Trainers and athletes have seen huge performance gains from red light therapy, but that’s just the front end of the benefits of using a Joovv for training. Research also shows that red light therapy prevents muscle soreness and fatigue from strenuous workouts.
How? Natural red and near infrared light helps promote antioxidants, which play a central role in reducing the oxidative stress associated with muscle fatigue. Antioxidants also increase the production of heat proteins—special proteins that help protect cells from stress and early cell death. [7,8] Studies have also identified an increase in circulation following light therapy, indicating tissues are receiving more oxygen and other nutrients important for healing—while also ridding themselves of toxic byproducts.  Red light therapy also helps reduce inflammation that can lead to cell damage. [10,11,12]
The graphic below shows some of the most compelling research on how red light leaves you feeling better after a workout:
Red Light Therapy Prevents Muscle Soreness and Fatigue
Here's an overview of the clinical research on light therapy and the prevention of muscle soreness, with samples from representative studies & trials published in peer-reviewed journals.
Less Delayed Onset Muscle Soreness: Researchers in a 2014 trial assessed the skeletal muscular performance and recovery after exercise for healthy men. They found that pre-exercise light therapy “significantly increases performance, decreases DOMS, and improves biochemical markers related to skeletal muscle damage.”*
Less Soreness & Damage After Intense Workouts: Researchers in a 2014 trial tested red light therapy for the muscle recovery of healthy young men after undergoing a “damaging eccentric exercise.” The light therapy group showed significantly reduced muscle strength loss, less muscle soreness, and fewer range of motion impairments.**
Less Damage After Running: A 2012 trial concluded that runners in the light therapy group experienced decreased “exercise-induced oxidative stress and muscle damage.” Researchers stated that the modulation of the redox system by light therapy likely led to a delay and reduction in skeletal muscle fatigue after running.***

Large Base of Clinical Research Shows Red Light Therapy Enhances Muscle Recovery
One of the biggest reasons people use Joovv is for faster muscle recovery. From pro athletes and elite trainers, to weekend warriors, to senior citizens, red light is helping people come back faster from pain and strain, so they can train more and perform better.
Recovering from Demanding Workouts: Researchers in 2014 found that light therapy lessens muscle soreness after strenuous exercise, and also that a single red light therapy treatment immediately after a damaging exercise was effective at reducing muscle soreness and strength loss. 
Red Light Therapy Beats Cryotherapy For Muscle Recovery: A 2016 study evaluated both cryotherapy and red light therapy for muscle recovery. Researchers found that light therapy alone was “optimal for post-exercise recovery,” with decreased DOMS and creatine kinase activity versus placebo or cryotherapy. 
Pro Athletes Thriving with Red Light Therapy: The graphic below highlights a few impressive studies that showed pro athletes recovered a lot faster with the help of red light therapy:
Pro Athletes Use Red Light Therapy for Muscle Recovery
The documented clinical results match the muscle recovery benefits Joovv users see every day, including many pro athletes.
Pro Volleyball Players Recover Faster with Red Light Therapy: Researchers in a double-blind, placebo-controlled trial tested pro volleyball players and stated this about the light therapy group,“Post-exercise levels of biochemical markers decreased significantly: Blood Lactate, Creatine Kinase, and C-Reactive Protein levels.”*
Pro Ruby Players Rely on Red Light Therapy: A 2016 study assessed male rugby players' endurance, speed, and ability to recover from demanding games and workouts. Researchers found that red light therapy accelerated the players’ recovery times, leading the authors of the study to recommend red light therapy for athletic recovery.**
