The goal of this randomized controlled clinical trial is to identify and compare the impacts of traditional concurrent training and concurrent training consisting of strength training combined with dance classes on functional performance, cognitive function and quality of life in older people. The main question it aims to answer are:
• The concurrent training consisting of strength training combined with dance classes can provide similar benefits to traditional concurrent training in neuromuscular and cardiorrespiratory performance, cognitive function and quality of life in older people?
Participants will training one of the two types of concurrent training (traditional concurrent training or concurrent training consisting of strength training combined with dance classes), two times a week, over 12 weeks.
Researchers will compare traditional concurrent training, concurrent training consisting of strength training combined with dance classes and a control group without exercise to see if this modalitys of physical exercise can provide increases in neuromuscular and cardiorrespiratory performance, cognitive function and quality of life in older people.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Traditional concurrent training | Experimental | The subjects will perform two concurrent training sessions, of approximately one hour per week. Composed of strength exercises and aerobic exercise (walking outdoors and/or treadmill). |
|
| Concurrent training consisting of strength training combined with dance classes | Experimental | The subjects will perform two concurrent training sessions associated with dance classes, of approximately one hour per week. Composed of strength exercises and dance classes. |
|
| Control | No Intervention | Subjects will be instructed to maintain their usual routine during the study period. |

| Traditional concurrent training | Behavioral | The subjects will perform two sessions per week of traditional concurrent training, consisting of strength training followed by aerobic exercise over 12 weeks, with progressive intensities and training volumes. Each traditional concurrent training session will consist of specific warm-up performed on equipment for upper and lower limbs with a load of less than 30% of the training load. Then the bench press, low row, leg press, extension and knee flexion exercises will be performed. Participants will be instructed to perform the concentric phase of the movement in one second and the eccentric phase in two seconds. After strength training, aerobic training (walking outdoors or on a treadmill) will be performed with intensity based on the adapted BORG effort perception scale (ranged to 0 = minimum effort, to 10 = maximal effort). |

| Concurrent training consisting of strength training combined with dance classes | Behavioral | Each concurrent training session associated with dance classes will consist of the same strength training as the traditional concurrent training group, but the traditional aerobic training will be replaced by a dance class. Each dance class will consist of a 5-minute general warm-up with joint mobility exercises and dynamic stretching. Then the main part will be performed with the elaboration of choreography, lasting approximately 20 minutes. Finally, there will be a 5-minute cool-down with stretching exercises. Classes will be held in four different dance modalities, divided into four modules. |
