Comparison of open-skill and closed-skill exercises in improving the response inhibitory ability of the elderly: a protocol for a randomised controlled clinical trial.

Introduction As people age, they are more likely to experience a decline in their response inhibition ability, which interferes with daily life. Previous studies have shown that exercise intervention can improve the cognitive ability of the elderly, but research on open-skill and closed-skill exercises to improve the response inhibition in this age group is still limited. This study will explore the advantages of long-term intervention of table tennis (open-skill exercise) compared with fit aerobics (closed-skill exercise) on the response inhibitory ability of the elderly. Methods and analysis A single-blind randomised controlled trial will be conducted. A total of 90 elderly subjects will be recruited and allocated randomly to the following groups: table tennis, fit aerobics and control. The interventions for the table tennis group and the fit aerobics group will be implemented in three 60 min sessions per week for 6 months; the control group will receive no exercise intervention. The primary assessment will be behavioural indicators of response inhibitory ability in the elderly based on the stop signal task. The secondary outcomes will include cognitive ability, mental status and depression in the elderly. Assessments will be conducted at baseline, 3 months, 6 months and 12 months. Ethics and dissemination This study was approved by the Shanghai University of Sport Research Ethics Committee (102772019RT012) and will provide reference for the advantages of table tennis compared with other types of sports in improving the response inhibitory ability of the elderly. The results of this study will provide a theoretical basis for choosing the best exercise programme to improve the response inhibitory ability of the elderly. Trial registration number This study has been registered prospectively in the Chinese Clinical Trial Registry (ChiCTR2100043616, 23 February 2021).
