Benefits of photobiomodulation (PBM) have been known for several decades. More recently, PBM applied in sports offers a special chance to support the modeling of the performance and recovery. Increasingly complex physical activities and fierce competition in the world of sports generate a state of psycho-emotional and physical stress that can induce chronic fatigue syndrome, failure in physical training, predisposition to muscle damage, physical and emotional exhaustion etc., for which PBM could be an excellent solution. To evaluate and identify all risk factors and the influence of PBM on health and performance in sport and for a better understanding of its effects, we did a search for “Photobiomodulation and Sports” on PubMed, to update the PBM science applied in sports, and we retained for analysis the articles published from 2014 to date. The term “PBM” is recent, and we did not include previous studies with “low level laser therapy” or “LLLT” before 2014. In the present research, PBM has been shown to have valuable protective and ergogenic effects in 25 human studies, being the key to success for high performance and recovery, facts supported also by 22 animal studies. PBM applied creatively and targeted depending on sport and size of the level of physical effort could perfectly modulate the mitochondrial activity and thus lead to remarkable improvements in performance. PBM with no conclusive results or without effects from this review (14 studies from a total of 39 on humans) was analyzed and we found the motivations of the authors from the perspective of multiple causes related to technological limitations, participants, the protocols for physical activity, the devices, techniques and PBM parameters. In the near future, dose–response experiments on physical activity should be designed and correlated with PBM dose–response studies, so that quantification of PBM parameters to allow the energy, metabolic, immune, and neuro-endocrine modulation, perfectly coupled with the level of training. There is an urgent need to continuously improve PBM devices, delivery methods, and protocols in new ingenious future sports trials. Latest innovations and nanotechnologies applied to perform intracellular signaling analysis, while examining extracellular targets, coupled with 3D and 4D sports motion analysis and other high-tech devices, can be a challenge to learn how to maximize PBM efficiency while achieving unprecedented sports performance and thus fulfilling the dream of millions of elite athletes.

“…The best increase was found for the 660 nm (red) group comparatively with the control, BFR, and the 830 nm (IR) group. Joining PBMT (660 nm) and BFR was effective for growing the handgrip strength of the wrist extensors, related to an enhancement of the electromyographic behavior [30].…”

“…The studies include 219 participants. One of the studies focused on patients with hand osteoarthritis [15], while four studies were conducted on healthy participants [16][17][18][19]. Hand grip strength was evaluated in two studies, one using the Jamar hydraulic dynamometer [16] and the other using a digital dynamometer [15].…”

Hand grip strength was evaluated in two studies, one using the Jamar hydraulic dynamometer [16] and the other using a digital dynamometer [15]. Shoulder muscle strength was evaluated in three studies: one utilized isokinetic testing and a dynamometer for shoulder internal and external rotators [17], second one using manual muscle testing for the supraspinatus and external rotators [18], and the third using a hand-held dynamometer for shoulder abductors, internal and external rotators [19].…”

Objective This systematic review aims to investigate the effect of blood flow restriction training (BFRT) on upper extremity muscle strength in pathological conditions of the upper extremity musculoskeletal system or in healthy individuals. Materials and Methods This study was conducted in accordance with the PRISMA guideline statement. The randomized controlled studies which published from January 2000 to May 2022 were searched in the PubMed, Web of Science, MEDLINE, Scopus, and Cochrane Library databases. Inclusion criteria were healthy clinical population or musculoskeletal pathology related to the upper extremity, participants aged 18 and above, application of blood flow restriction to the arm, a randomized controlled study design, and publication in English. Additionally, the presentation of upper extremity muscle strength as an outcome measurement was required. The quality of the studies was evaluated using The Physiotherapy Evidence Database (PEDro) scale. Articles that were non-randomized, inaccessible in full text, and scored 4 or below on the PEDro scale were excluded. Results Five studies were included with 219 participants. The included studies had PEDro scores ranging from 5 to 8, with an average score of 6.4. This review demonstrated a positive or neutral effect of BFRT on grip strength and shoulder strength. Conclusion Although some studies have reported positive effects of BFRT on upper extremity muscle strength, there is no conclusive evidence regarding the protocol to be used for increasing upper extremity muscle strength.
