Psychological readiness is related to return to sport in judo injuries: a cross-sectional study
ConclusionBased on the data of this study, type of injury, sport level, treatment method, and gender appear to influence psychological readiness on judoka and their ability to return to sport. The multiple factors that influence a judoka and their ability to return to sport argue for individualized treatment of judoka and their psychological state after injury in the return to sport process.

Relative age effects on speed trials in Brazilian athletics
ConclusionThe results allow us to conclude that there is a RAE in the speed trials of Brazilian athletics in the U16 and U18 categories for men, while this effect appears only in the shallow trials of the U18 category for women, indicating that the RAE has incidence when there is more participation and competition in the sport.

Allometric normalization of handgrip strength in older adults: Which body size parameter is the most appropriate?
ConclusionBased on the study results, body height seems to be the best body size parameter for handgrip strength normalization in older adults, omitting the influence of body size on strength performance. If handgrip strength is measured, body height may help normalize strength for large-scale research. (Source: BMC Sports Science, Medicine and Rehabilitation)

High-intensity circuit training change serum myostatin but not myogenin in adolescents ’ soccer players: a quasi-experimental study
ConclusionThese results suggest that eight weeks of HICT can decrease the resting serum values of MSTN but not change the resting serum values of MyoG in male adolescent soccer players. Also, eight weeks of HICT does not affect the acute response of MSTN and MyoG after a maximum aerobic test. (Source: BMC Sports Science, Medicine and Rehabilitation)

Validity of using perceived exertion to assess muscle fatigue during back squat exercise
AbstractThe rating of perceived exertion (RPE) scale has been found to reflect physiological responses, and this study aimed to assess the validity of using the Borg CR-10 scale and velocity loss to evaluate muscle fatigue quantified by surface electromyography during back squat (BS) exercise. A total of 15 collegiate male athletes underwent three non-explosive BS tasks comprising low, medium, and high volumes at 65% of their one-repetition maximum. RPEs, spectral fatigue index (SFI), and velocity loss during BS exercise were assessed throughout the trials. Significant differences in overall RPE (p <  0.001) and ave...

The effects of online pilates and face-to-face pilates in healthy individuals during the COVID-19 pandemic: a randomized controlled study
ConclusionsAs a result, healthy individuals have seen similar benefits in online and face-to-face pilates. Both methods are significant for gaining healthy habits and increasing physical activity in healthy individuals.Trial registration Retrospectively registered.

Correlations between physical activity and quality of life in entrepreneurs from Wroc ław, Poland
ConclusionPrograms promoting physical activity among entrepreneurs, which focus on moderate and high intensity exercise, should be considered desirable in the context of the study findings. Activities aimed at improving quality of life in the physical and psychological domains as a potential determinant of the level of physical activity of entrepreneurs are also worth recommending.

Eccentric exercise is more effective than other exercises in the treatment of mid-portion Achilles tendinopathy: systematic review and meta-analysis
AbstractAchilles tendinopathy (AT) is one of the most frequent overuse injuries in the ankle. The evidence base for its conservative management AT continues to evolve, but there is still a gap in the evidence for the efficacy of any modality of treatment in high-quality studies. This systematic review and meta-analysis investigated the efficacy of EE in improving pain and function in adult patients with mid-portion Achilles tendinopathy compared to other forms of exercise. A search was performed in PubMed, BIREME, SportDiscus, Cinahl, Web of Science and PEDro, in November 2022. The methodological quality was evaluated usin...

Does inflammation markers or treatment type moderate exercise intensity effects on changes in muscle strength in cancer survivors participating in a 6-month combined resistance- and endurance exercise program? Results from the Phys-Can trial
ConclusionsThe effect of exercise intensity on muscle strength is not moderated by TNF α, IL6, neo/adjuvant chemotherapy, or ADT, and therefore cannot explain any intra-variation of training response regarding exercise intensity (e.g., strength gain) for BRCA or PRCA in this setting.Trial registration: ClinicalTrials.gov NCT02473003.

Effect of wearing medical protective masks on treadmill running performance in the postpandemic era: a randomised trial
ConclusionsWearing a medical protective mask does not affect the joint angle and touchdown PVGRF of lower extremities during treadmill running while affected by running time and changed after 9  min-treadmill running. Future studies will examine the effects of wearing masks during the pandemic on muscle activation and blood biochemical values during exercise.Trial registration No. ChiCTR2000040535 (date of registration on December 1, 2020).
