The goal of our study was to investigate the effect of 2 consecutive badminton matches among elite badminton players on visuomotor integration, dynamic balance ability, inhibitory control, short-term memory capacity, and changes in cardiovascular fitness. Badminton is the fastest racket sport regarding the speed of the shuttle leaving the racket. The play with open move skills is characterized by series of short range and high intensity workload phases. The effectiveness is affected by the execution of the specific movement techniques within a certain time period and the optimal function of decision-making techniques. The experiment included a tournament with 2 simulated matches among elite, adult, male badminton players. The quality of visuomotor integrity and dynamic balance task were measured with Blazepod modified adapted Y-Balance Test induced reactive balance test, pre and post matches. Stroop test was used to evaluate the inhibition capability, and Digit Span Test was applied to measure the cognitive short-term capacity. Remarkable changes could not be detected in the visuomotor reaction in each time points. Gradual increase was observed in balance errors due to the dominant leg (right) support. Digit Span Test decreased between pre and post match measurements, however, significant changes (P < .01) could be detected after the restitution period between pre and post match. No alteration could be seen with Stroop test in each time points, nevertheless, notable increase in false results were observed at the 4th measurements points. Heart rate did not remarkably differ. In summary, the intensive, consecutive strength had a negative effect on peripheral system, and therefore on dynamic balance control. Cognitive ability indicated gradual deterioration, but showed optimal regeneration between loads.

Objective: To determine the effects of exergaming (EXE) on quality of life (QOL), motor, and clinical symptoms in multiple sclerosis (MS). We compared the effects of EXE, balance (BAL), cycling (CYC), proprioceptive neuromuscular facilitation (PNF), and a standard care wait-listed control group on clinical and motor symptoms and quality of life (QOL) in people with MS (PwMS) and determined the effects of subsequent maintenance programs for 2 years in a hospital setting. Design: A randomized controlled trial, using before-after test design. Setting: University hospital setting. Participants: Of 82 outpatients with MS, 70 were randomized (N=70), and 68 completed the study. Interventions: The initial high-intensity and high-frequency interventions consisted of 25 one-hour sessions over 5 weeks. After the 5-week-long initial intervention, the 2-year-long maintenance programs followed, consisting of 3 sessions per week, each for 1 hour. Main Outcome Measures: The primary outcome: Multiple Sclerosis Impact Scale (MSIS-29). Secondary outcomes: Measures 5 aspects of health-related QOL (EuroQol 5-Dimension questionnaire), Beck Depression Inventory, 6-minute walk test (6MWT), Berg Balance Scale (BBS), Tinetti Assessment Tool (TAT), and static BAL (center of pressure). Results: MSIS-29 improved most in EXE (11 points), BAL (6), and CYC (6) (all P<.05). QOL improved most in EXE (3 points), CYC, and BAL (2) (all P<.05). TAT and BBS improved significantly (P<.05) but similarly (P>.05) in EXE, BAL, and CYC. 6MWT improved most in EXE (57m), BAL (32m), and CYC (19m) (all P<.001). Standing sway did not change. Maintenance programs further increased the initial exercise-induced gains, robustly in EXE. Conclusions: A total of 25 sessions of EXE, BAL, CYC, and PNF, in this order, improved clinical and motor symptoms and QOL, and subsequent 2-year-long thrice weekly maintenance programs further slowed symptom worsening and improved QOL. EXE was the most and PNF was the least effective to improve clinical symptoms, motor function, and QOL in PwMS.

Introduction: There are scant data to demonstrate that the long-term non-pharmaceutical interventions can slow the progression of motor and non-motor symptoms and lower drug dose in Parkinson's disease (PD). Methods: After randomization, the Exercise-only (E, n = 19) group completed an initial 3-week-long, 15-session supervised, high-intensity sensorimotor agility exercise program designed to improve the postural stability. The Exercise + Maintenance (E + M, n = 22) group completed the 3-week program and continued the same program three times per week for 6 years. The no exercise and no maintenance control (C, n = 26) group continued habitual living. In each patient, 11 outcomes were measured before and after the 3-week initial exercise program and then, at 3, 6, 12, 18, 24, 36, 48, 60, and 72 months. Results: The longitudinal linear mixed effects modeling of each variable was fitted with maximum likelihood estimation and adjusted for baseline and covariates. The exercise program strongly improved the primary outcome, Motor Experiences of Daily Living, by ~7 points and all secondary outcomes [body mass index (BMI), disease and no disease-specific quality of life, depression, mobility, and standing balance]. In E group, the detraining effects lasted up to 12 months. E+M group further improved the initial exercise-induced gains up to 3 months and the gains were sustained until year 6. In C group, the symptoms worsened steadily. By year 6, levodopa (L-dopa) equivalents increased in all the groups but least in E + M group. Conclusion: A short-term, high-intensity sensorimotor agility exercise program improved the PD symptoms up to a year during detraining but the subsequent 6-year maintenance program was needed to further increase or sustain the initial improvements in the symptoms, quality of life, and drug dose.
