Background: Anxiety and depression are prevalent after spinal cord injury, impairing social participation and quality of life. Objective: This study aimed to investigate the effects of traditional resistance training (TRT), flywheel resistance training (FWRT), and high-velocity resistance training (HVRT) on the mental health and quality of life in individuals with spinal cord injury. Methods: Thirty-two participants were divided into TRT (n = 12), FWRT (n = 8), and HVRT (n = 12) groups, undergoing 8 weeks of upper-limb training twice weekly under super-vision. Training intensity and volume were progressively increased. The Hospital Anxiety and Depression Scale and SF-36 Questionnaire were used to assess outcomes. Results: Both the TRT and FWRT groups showed a reduction in HADS-D scores post-intervention (p < 0.001). The TRT group also presented a significant reduction in HADS-A scores post-intervention (p = 0.003). Concerning quality of life, after training, TRT showed improvements in social functioning (p = 0.013), FWRT improved scores in physical functioning (p = 0.002), bodily pain (p = 0.002), vitality (p = 0.046), and role emotional (p < 0.001), while HVRT enhanced role physical (p < 0.001), social functioning (p = 0.013), and role emotional (p < 0.001). Conclusion: Overall, TRT was the most effective in reducing anxiety and depression and enhancing quality of life, while FWRT showed notable gains in physical and functional capacity. HVRT demonstrated improvements primarily in role physical but was less effective in other domains.

Introduction: Spinal cord injury (SCI) is a debilitating condition that causes motor, physiological, and sensory impairments, potentially leading to permanent disability, increased morbidity, and mortality, ultimately impacting an individual's quality of life (QoL). Physical exercise emerges as an effective alternative to mitigate these consequences and uphold the autonomy and QoL for this population. Detraining (DT), defined as the partial or total loss of adaptations induced by physical training in response to its complete interruption or insufficient stimulus, represents a significant concern. The objective of this systematic review was to conduct a comprehensive literature review regarding the current state of knowledge on the potential impacts of DT on the health of individuals with SCI. Method: The search was conducted on PubMed, Web of Science, Embase, SPORTDiscus, and Cochrane databases using relevant English terms (("Detraining") AND ("Spinal Cord Injury")) and their synonyms. Due to the limited number of studies addressing this topic, no specific time frame was set for study eligibility. Results: The literature search was performed in November 2023, yielding 42 results, from which 15 remained after removing duplicates. Two articles were excluded following title analysis. Thirteen abstracts were reviewed, and 7 were excluded, leaving 6 articles for full analysis. Due to the nature of the studies, a meta-analysis was not conducted. Conclusion: DT resulted in alterations in body composition (BC), including increased body fat and reduced muscle mass, especially following the interruption of testosterone-associated training. Additionally, the cessation of training impacted the metabolic profile, leading to changes in glucose, lipids, and insulin sensitivity. Furthermore, hemodynamic variables, such as blood pressure (BP) and heart rate (HR), underwent changes, elevating the risk of cardiovascular complications. Regarding cardiorespiratory components, there was a decline in peak oxygen consumption (VO2peak) following the DT period. Halting exercise can lead to detrimental health consequences, underscoring the imperative of maintaining consistent physical training for these individuals.

Spinal cord injury (SCI) is a condition that significantly affects the quality of life (QoL) of individuals, causing motor, physiological, social, and psychological impairments. Physical exercise plays a crucial role in maintaining the health and functional capacity of these individuals, helping to minimize the negative impacts of SCI. The aim of this study was to evaluate the effect of detraining (DT) (reduction or cessation of physical exercise) during the pandemic on five individuals with thoracic SCI. We assessed muscle strength using strength tests, functional capacity using a functional agility test, mental health using anxiety and depression inventories, and body composition using dual-energy X-ray absorptiometry (DEXA). The results after 33 months of DT showed significant losses in functional agility and MS, as well as a worsening in symptoms of anxiety and depression. It was observed that total body mass and fat mass (FM) exhibited varied behaviors among the individuals. Similarly, the results for lean body mass were heterogeneous, with one participant showing significant deterioration. It is concluded that DT caused by the pandemic worsened the physical and mental condition of individuals with SCI, highlighting the importance of continuous exercise for this population and underscoring the need for individual assessments to fully understand the impacts of DT.
