Table 7: Post-intervention comparison on the Senior Fitness Test battery variables of the CG and the EG according to sex. non-significant. With this increase, we could be contributing to reducing the risk of falls in older adults [49; 50]. The results obtained in upper body strength, once the multicomponent exercise program was completed, show that the EG participants performed significantly more repetitions in the upper body strength test. These results are in line with previous studies [46] that indicate that, with directed strength work, strength in the upper body increases significantly. Regarding lower body flexibility, EG participants achieved better results in this test after the multicomponent intervention program than before, results that are consistent with similar previous studies [46; 51]. In upper body flexibility, as in upper body strength, there were no statistically significant differences. This may be due to the fact that some body areas and their muscles are negatively affected compared to others that remain relatively preserved with age [52]. It could also be because when strength training was incorporated, the changes in flexibility did not reach significant changes, in this case, in the upper part of the body [53]. On the other hand, the results regarding dynamic balance indicate that the EG participants performed this test in less time than those in the CG, both before and after the multicomponent intervention program, but not significantly. Our results were not consistent with those obtained by [PERSON] et al. [49] and [PERSON] et al. [54], who indicated that interventions that contained strength exercises such as the applied multicomponent program had positive effects on dynamic balance (i.e., balance and movement speed) mainly due to the stimulation of the propriceptors of the knee or the improvement in lower body strength [55], which was expected in this research. Regarding right and left manual dynamometry, neither before nor after the intervention with the multicomponent exercise program were there significant differences between both groups. These results are consistent with studies such as those by [PERSON] et al. [56] or [PERSON] et al. [57], since these values decrease with advancing age and lack of exercise. However, in the EG, an increase in manual dynamometry was expected since the results of [PERSON] et al.
