Background Exercises are an effective treatment in Parkinson’s disease (PD), but there is still controversy over which types should be used. We aimed to compare and rank the types of exercise that improve PD symptoms by quantifying information from randomised controlled trials. Methods We performed a systematic review and network meta-analysis and searched PubMed, MEDLINE, Embase, PsycINFO, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and China National Knowledge Infrastructure (CNKI) from their inception date to June 30, 2022. We included randomized controlled trials of 24 types of exercise for the interventional treatment of adults (≥ 50 years old) with PD. Effect size measures were standardized mean differences (SMDs) with 95% credible intervals (CrIs). The confidence of evidence was examined using Confidence in Network Meta-Analysis (CINeMA). Results We identified 10 474 citations and included 250 studies involving 13 011 participants. Results of NMA showed that power training (PT) had the best benefits for motor symptoms compared with the control group (CON), with SMDs (95% CrI) (-1.46, [-2.18 to -0.74]). Body weight support treadmill training (BWS_TT) showed the best improvement in balance (1.55, [0.72 to 2.37]), gait velocity (1.15 [0.57 to 1.31]) and walking distance (1.96, [1.18 to 2.73]), and robotic assisted gait training (RA_GT) had the most benefits for freezing of gait (-1.09, [-1.80 to -0.38]). For non-motor symptoms, Dance showed the best benefits for depression (-1.71, [-2.79 to -0.73]). Only Yoga significantly reduced anxiety symptom compared with CON (-0.53, [0.96 to -0.11]). Only resistance training (RT) significantly enhanced sleep quality and cognition (-1.42, [-2.60 to -0.23]; 0.51, [0.09 to 0.94]). For muscle strength, PT showed the best advance (1.04, [0.64 to 1.44]). For concern of falling, five types of exercise were more effective than CON. Conclusions There is low quality evidence that PT, Yoga, BWS_TT, Dance, and RT are the most effective treatments, pending outcome of interest, for adults with PD. Trial registration PROSPERO (CRD42021220052).

Our objective in this paper was to systematically review evaluations of the effects of exercises on pain symptoms and activities of daily living (ADL) in middle-aged and elderly patients with low back pain (LBP). We searched Web of Science, PubMed, EBSCO, and China National Knowledge Internet (CNKI) databases for randomized controlled trials (RCTs) on this topic. We evaluated the methodological quality of included articles using the Physiotherapy Evidence Database (PEDro) scale, and we statistically analyzed these studies using RevMan software. We reviewed 18 RCTs (23 comparison groups) with a total of 910 participants, and our meta-analysis confirmed that exercises significantly improved both pain and ADLs measured on visual analog scales (VAS) (SMD = −0.91, 95% CI: [−1.3, −0.52], p < 0.00001) and on the Oswestry Disability Index (ODI) (SMD = −2.07, 95% CI: [−3.19, −0.96], p < 0.00001). We conclude that exercises can reduce pain severity and improve ADL capacity in middle-aged and elderly persons with LBP, confirming that exercise can serve as a medical intervention for these indivdiuals. However, given the high heterogeneity of responses among individual participants, there remains a need for further study.

Muscle strength after detraining is still higher than the level before training, which is an important issue for middle-aged and older adults. The purpose of the present study was to examine the effects of detraining duration (DD), resistance training duration (RTD), and intensity on the maintenance of resistance training (RT) benefits after detraining in middle-aged and older adults. A systematic search yielded 15 randomized control trails (n = 383) eligible for inclusion. The results showed that RTD ≥ 24 weeks and DD ≥ RTD, the RT benefits were still significantly maintained even with medium and low intensity (standardized mean difference = 1.16, 95% confidence interval, CI [0.38, 1.94], p = .004). When RTD < 24 weeks and DD ≤ RTD, only the high-intensity groups maintained the RT benefits (DD, 4–6 weeks: standardized mean difference = 0.71, 95% CI [0.34, 1.08], p = .0002; DD 8–16 weeks: standardized mean difference = 1.35, 95% CI [0.66, 2.04], p = .0001). However, when DD > RTD, the RT benefits were not maintained even with high intensity. In summary, when RTD was less than 24 weeks, RTD > DD was an important factor in maintaining muscle strength.

The present study aimed to review the research literature on aquatic exercise for health promotion using bibliometric methods and CiteSpace software. The number of studies related to this topic are constantly expanding, with the USA, Brazil, and Australia the centers of this research. Most published papers fall within Sports Science, but the disciplines of Physiology, Psychology, and Rehabilitation were also found to be dominant domains for this literature. The seven most prolific authors were from Brazil or Spain. The most frequently cited references focused on sub-topics of physiology, biochemistry, physical fitness, psychological health, cardiovascular disease, and joint disease. New research trends have shifted to the promotion of cardiovascular health in clinical populations (stroke, overweight, hypertension, endothelium dysfunctional, obese, inflammation, antioxidant, heart failure). Overall, this review found that research hot spots and trends in this realm have focused on improving cardiovascular health with aquatic exercise.
