A cross-sectional survey was distributed to 1322 members of a 1-on-1 personalized strength training studio. A total of 366 respondents ( = 134 male and = 232 female), all aged over 20 years, reported considerable training experience, with 55% of the males and 42% of the females reporting 5+ years of experience. The data were analyzed and reported descriptively with differences >5% identified based on the use of a 5-point Likert scale, the sample size, and the nature of the observations. Disparities between the males and females were identified; the males reported higher perceptions of managing effort, technique, and programming without supervision compared to the females. Safety was noted as being more important to the females compared to the males. Qualitatively, additional themes were raised including an analogy of the personal relationship between the trainer and trainee being similar to that between medical professionals and patients. This was validated where the participants discussed their adaptations from supervised strength training for maintaining quality of life in aging and recovering from medical conditions and injury. The data are discussed in the context of a previous body of literature suggesting males falsely report higher levels of confidence in tasks compared to females, particularly in relation to effort, role models, and verbal encouragement. We posit that the greater confidence expressed by males at least partially explains the greater engagement in strength training practices by males compared to females, as well as explaining the higher level of participation in supervised strength training by females compared to males. This research proves beneficial for strength training practitioners in enhancing their understanding and expectations of clients, as well as hopefully proving insightful in engaging more people in strength training.

Purpose: The effect of skeletal muscle mass of the trunk and extremities on sagittal imbalance of the spine before and after surgery for adult spinal deformity (ASD) has not been elucidated. The purpose of this study was to examine the correlation between reduced skeletal muscle mass of the trunk and extremities, as well as spinopelvic parameters, preoperatively, postoperatively and at least 2 years after surgery for ASD.
Methods: This retrospective observational study included 140 consecutive patients who had undergone surgery for ASD and were followed-up for at least 2 years and whose skeletal muscle mass could be measured preoperatively using whole-body dual-energy X-ray absorptiometry.

Background: The emergence of 3D printing has revolutionized medical training and preoperative planning. However, existing models have limitations, prompting the development of newly designed flexible 3D-printed bone fracture models.
Methods: The designed flexible 3D-printed bone fracture models were evaluated by 133 trauma surgeons with different levels of experience for perceived value as educational tool or as preoperative planning tool.

Background: Brain-derived neurotrophic factor (BDNF) may help middle-aged and older adults resist age-related neurodegenerative conditions and psychiatric disorders. Recent studies suggested that Traditional Chinese exercises (TCEs) may be a promising strategy to improve the BDNF levels of these populations, while the effectiveness has yet to be definitively confirmed due to the variances in the study designs and observations. Therefore, this systematic review and meta-analysis aimed to examine the effects of TCEs intervention on BDNF in middle-aged and older adults.

Background: : Neuromuscular re-education has focused on improving motor activities in patients with pathologies by retraining the nervous system. However, this has not yet been investigated in healthy individuals. Voluntary isometric contractions at maximal muscle shortening (VICAMS) is a new technique with the same objective.

Impairments on body function, activities of daily living (ADL) and cognition are common after stroke. Eccentric resistance training (ERT) may be implemented to improve them. The primary objectives were to evaluate whether ERT improves body function, ADL and cognition after stroke.
