The aim of the study is to evaluate and to compare the effects of two exercise regimes (Boxing Training -BT and Multicomponent Training -MT) and 12 weeks of follow-up 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. Participants of all groups will be assessed for Senior Fitness test, and body weight at 4 moments (baseline, 12 weeks and 24 weeks of exercise and a follow-up period lasting 12 weeks).
Our hypotheses are:
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.

| Baseline, 6 months |
| Change from Baseline cognitive performance (Selective recall test) at 6 months | Selective recall test [SRT-List A; parameters: consistent long-term recall, long-term storage, delayed recall, and intrusions] to assess verbal learning and multiple-trial memory (14). | Baseline, 6 months |
| Change from Baseline cognitive performance (Verbal short-term memory and verbal working memory) at 6 months | The forward digit advancement (DS) test was selected to assess verbal short-term memory and the backward DS to assess verbal working memory (subtest of the Wechsler test of intelligence for adults WAIS III) and total DS score (total DS; calculated by adding forward DS and backward DS) (14, 16). | Baseline, 6 months |
| Change from Baseline cognitive performance (Memory) at 6 months | Consortium to establish a registry for the Alzheimer's Disease List Test (CERAD), will be used: word list memory; word list recall; and word list recognition. The parameters: total hits and delayed recall hits (13, 14). | Baseline, 6 months |
| Change from Baseline Psychological testing (Depression) at 6 months | The geriatric depression scale (GDS, short version) (18) will be used for depressive symptoms assessment. The GDS-15 evaluates depressive symptoms during the last week and has a dichotomous response scale (Yes/No). On 10 items (2, 3, 4, 6, 8, 9, 10, 12, 14, 15) the answer Yes is rated 1 point and on the remaining items (1, 5, 7, 11, and 13) the answer No is rated 1 point, in the sense that the score indicates presence of depressive symptomatology. The total score of the items is processed by summing the scores on the 15 items, ranging from 0 to 15 points. The 15-item version of the GDS showed the ability to differentiate depressed from nondepressed subjects (18). | Baseline, 6 months |
| Change from Baseline Psychological testing (Anxiety and depression) at 6 months | Hospital Anxiety and Depression Scale (HADS) will be used (19). Although the HADS is considered an effective instrument for assessing depressive symptoms in hospital settings, it is a screening measure, and it is of utmost importance to be followed by a psychological assessment. This scale consists of two subscales, one for anxiety and the other for depression. A score between 0 to 7 means absence of depressive or anxious symptoms; a score between 8 to 10 means a possible case of depression or anxiety; and from 11 to 21 as a probable case. | Baseline, 6 months |
