Healthy People Programs Clinical Trial
Official title:
Impact of Boxing-based Training Program on Physical-functional Fitness, Cognitive Performance, and Risk of Falls in Community-dwelling Older Adults
The aim of the study is to evaluate and to compare the effects of two exercise regime (Boxing Training -BT and Multicomponent Training -MT) on cognitive health status, physical-functional fitness, and risk of falls in community-dwelling elders. This is a quasi-experimental controlled trial using a parallel-group design. Participants will be allocated to 3 groups (i.e. BT, MT or control group [no intervention]). Both exercise programs (BT and MT) will last 24 weeks, twice a week, 45 minutes per session. Only participants in the intervention groups (BT and MT) will be assessed for Senior Fitness test, and body weight at 3 moments (baseline, 12 weeks and 24 weeks). Participants in the control group will participate in the assessments (initial [baseline] and final [24 weeks]). Our hypotheses are: 1. In comparison with the control group, both exercise regimes groups (BT and MT) will positively impact on physical-functional fitness, cognitive health status and risk of falls in community-dwelling elders. 2. The observed effects on physical-functional fitness, cognitive health status, and risk of falls as a result of the BT program will be superior to the effects arisen from the MT exercise regime.
Aging is associated with functional and cognitive decline (1, 2), which are causal factors of falls in the elderly. According to available evidence, alleviation of these conditions can be achieved through regular exercise of the multicomponent type (MT) (3). However, in TM programs, "muscle power" takes a secondary role (5) although it is extremely important to preserve the integrity of the neuromuscular system (6). Studies indicate that combat sports may represent an exercise strategy that combines muscular fitness, cardiorespiratory fitness, agility, and balance (7), in addition to falling within the scope of dual-task programs (i.e., physical and cognitive) because they require memorization of combinations of attacking and defending movements, quick decision-making, and movement by coordinating simultaneous leg and hand movements (8). Seminal work with adapted boxing for elderly parkinsonians has demonstrated positive results in health indicators (9, 10). But the effectiveness of this modality in apparently healthy elderly is still unknown. Therefore, this project aims to compare the effects of boxing training and multi-component training on physical-functional fitness, cognitive performance, and the risk of falls in older people. The study comprises a quantitative quasi-experimental design, will be conducted in the metropolitan area of Porto, Portugal. The study sample will consist of healthy individuals from the community, aged ≥ 60 years, who will be recruited in community programs, municipalities, health centers, and social media platforms through phone calls and informational flyers. Those who accept to participate will be informed about the project objectives and procedures. Participation will be voluntary, and everyone will be required to sign the Free and Informed Consent form. Participants will be allocated into intervention groups: (Boxing training group or Multicomponent training group) or the Control Group (No intervention). The main results will be the physical-functional fitness measured through the Senior Fitness test, Cosmed K5b2, Handgrip strength, ball throw, isokinetic strength, cognitive performance evaluated by neurocognitive and psychological tests, in addition and the risk of falls evaluated by the Biodex® Balance System. Secondary outcomes will be brain activity by means of the electroencephalogram (EEG), bodycomposition, bone mineral density, quality of life and satisfaction with exercise. The research protocol will follow the CONSORT/SPIRIT guidelines. ;
