ABSTRACT

We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults.  相似文献   

改革开放40年高等体育教育资源优化配置的社会学审视     

张孔军  钱娅艳 《北京体育大学学报》2019,42(2):103-114

摘要：我国高等体育教育资源优化配置研究引入社会学视角理论与方法，理论与实践均取得专家的认同。运用文献资料法、专家访谈法和实地考察法等方法发现，在计划经济体制下我国高等体育教育资源配置主体单一性、手段行政化和政治倾向性强，凸显出高等体育教育资源配置缺乏激励机制和市场竞争机制的问题，造成高等体育教育资源配置成本最大化和社会效应的最小化问题较多。自改革开放以来,随着我国市场经济体制的建立为高等体育教育资源优化配置提供了难得的发展机遇，我国高等体育教育资源配置取得了明显成效，但仍然存在高等体育教育资源配置机制滞后、体制机制改革创新步伐缓慢、高等体育教育资源配置不合理以及民办普通高校体育教育资源配置严重不足等问题。据此，从社会学研究的视角，提出了构建多主体推动高等体育教育资源优化配置创新的发展模式、多元化高等体育教育资源优化配置资金投入的保障体系、高等体育教育资源优化配置均衡发展的运行机制和大学城体育教育资源“共建共享”的创新发展模式的新时代我国高等体育教育资源优化配置的发展策略，旨在服务新时代全民健身与全民健康深度融合发展，“推动构建人类命运共同体”发展目标的实现。  相似文献   

Cut points of the Actigraph GT9X for moderate and vigorous intensity physical activity at four different wear locations     

Matthew B. Rhudy  Scott B. Dreisbach  Matthew D. Moran  Marissa J. Ruggiero  Praveen Veerabhadrappa 《Journal of sports sciences》2020,38(5):503-510

ABSTRACT

Accelerometer cut points are an important consideration for distinguishing the intensity of activity into categories such as moderate and vigorous. It is well-established in the literature that these cut points depend on a variety of factors, including age group, device, and wear location. The Actigraph GT9X is a newer model accelerometer that is used for physical activity research, but existing cut points for this device are limited since it is a newer device. Furthermore, there is not existing data on cut points for the GT9X at the ankle or foot locations, which offers some potential benefit for activities that do not involve arm and/or core motion. A total of N = 44 adults completed a four-stage treadmill protocol while wearing Actigraph GT9X sensors at four different locations: foot, ankle, wrist, and hip. Metabolic Equivalent of Task (MET) levels assessed by indirect calorimetry along with Receiver Operating Characteristic (ROC) curves were used to establish cut points for moderate and vigorous intensity for each wear location of the GT9X. Area under the ROC curves indicated high discrimination accuracy for each case.  相似文献

Effects of an aerobic fitness test on short- and long-term memory in elementary-aged children     

Jennifer L. Etnier  Paul M. Sprick  Jeffrey D. Labban  Chia-Hao Shih  Stephen M. Glass  Jarod C. Vance 《Journal of sports sciences》2020,38(19):2264-2272

ABSTRACT

Meta-analytic evidence supports that exercise has benefits for short-term memory (STM) and long-term memory (LTM). However, only three studies with children have tested the differential effects of exercise on STM and LTM. The purpose of this study was to examine the effects of an aerobic fitness test on STM and LTM and to consider the moderating effects of grade level. Children (7–13 years of age) were randomly assigned to either perform an aerobic fitness test before (exercise prior) or after (exercise post) performing the Rey Auditory Verbal Learning Test (RAVLT) to assess memory. Memory was tested again after approximately 24 hours. There were significant differences in memory performance as a function of grade with 4^th and 6^th graders consistently outperforming 2^nd graders. For learning, Day 1 Retention, 24-hr recall, and Day 2 Retention, the exercise prior group performed better than the exercise post group. It is concluded that an aerobic fitness test performed prior to a declarative memory test benefits LTM as compared to when the aerobic fitness test is performed after the memory test.  相似文献
