1. Introduction
Osteoporosis (OP) represents a pathology of important health implications, which identifies its clinical significance in the fracture that occur as a consequence of increased bone fragility [1]. The standard treatment is fundamentally pharmacological and aims to reduce the incidence of fractures through the interruption of the resolution mechanism [2][3]. It appears that although the benefits outweigh the risks, the association between the combination of sequential antiresorptive/anabolic pharmacotherapeutic cycles and the reduction of fracture risk using aminobisphosphonates, selective estrogen receptor modulators, denosumab and teriparatide has not been demonstrated. However, when combined with exercise this would help maintain bone architecture thanks to increased bone mass and muscle strength [3][4][4,5]. Muscle strengthening exercise would be effective because it is believed to increase muscle mass and decrease fat mass, especially in osteoporotic menopausal women in whom, by stimulating osteogenesis, it would reduce falls and fractures [5][6][6,7].
In contrast, Ashe et al. [7][8], Sanudo et al. [8][9] and Asikainen et al. [9][10] have respectively highlighted the lack of efficacy of resistance exercise in elderly women, pointing out a non-significant positive effect on body loss in resistance protocols alone and showing how even the combination of aerobic and resistance training does not lead to improvements in terms of BMD, muscle strength, flexibility and coordination, even in programs lasting more than one year. In addition, Benedetti et al. [3][4] has reported the low efficacy of long-term muscle strengthening exercise in elderly women in terms of cortical volumetric bone mineral density when performed with own body weight or resistance. Perhaps this is due to the diversity of the exercise used in the research detailed in the existing literature, and to the different nomenclatures used: physical exercise, exercise, resistance training, strength training, weight-bearing exercise training, resistance training programs, land exercise program, aquatic exercise program, physical activity program, circuit training, high-intensity resistance and impact training, adapted physical activity exercise protocol, progressive load training, strengthening exercises and multicomponent training.
2. Exercise Effectiveness in Postmenopausal Women with Osteoporosis
Strength training aims to promote osteogenesis in women diagnosed with OP, however, no significant changes are observed in vitamin-D levels, but significant changes are observed in bone architecture in both protein matrix and bone (p = 0.00177, p = 0.00031) as well as in BMD. It seems that these changes would be more pronounced if the strength programs had a duration of 12 months [10][11][28,29].
Muscle strengthening exercise improves other capacities such as isometric and isotonic strength of large neuromuscular complexes of both the lower and upper limbs that seem to be key in the primary prevention of falls [12][30]. Furthermore, these improvements are related to work intensity, showing that interventions are required that work at least at an intensity of 80 to 85% 1RM to achieve the desired effects. Effects on balance are also observed, although these improvements do not seem to extend beyond 10 months, so we believe it is necessary that this ability be introduced as early as possible in training programs, especially if the intensity is high at a lower frequency. However, this last aspect has not been rigorously demonstrated because for many researchers it would be difficult to justify the use of high intensity in frail women diagnosed with OP To overcome this procedural obstacle, Watson et al. proposed in their LIFTMOR study to divide the program into two mesocycles of 6 months duration, avoiding that excessive load accumulation ends up putting these patients at risk [13][24].
Regarding the topic of exercise parameters, a 2020 review and meta-analysis by Shojaa et al., aiming to analyse the effects of dynamic muscle strengthening exercise on BMD in postmenopausal women [14][31], showed no significant difference in BMD between protocols with different duration of intervention and between different exercise intensities. On the contrary, it showed a significant difference with a positive effect on bone quality, in favour of training with free weights and a low net training frequency (<2 sessions/week).
On the other hand, it has been widely demonstrated that physical activity is able to promote bone formation, stimulating bone metabolism and its remodeling through mechanical loading (compression, tension and tissue shear) [15][16][32,33], improve hormonal regulation (estrogens, parathyroid hormone and glucocorticoids) [17][18][19][20][34,35,36,37] (with mimetic effect to hormone replacement therapy in postmenopausal women [21][38]), facilitate the regulation of signaling pathways [22][23][24][25][26][27][39,40,41,42,43,44], and stimulation of angiogenic-osteogenic responses [28][45]. However, and only from a clinical point of view, working in an aquatic environment may be a good approach to work in early phases due to the ease of working on the psychological and behavioral aspects associated with fear of movement.
Although not investigated in this review, considering the complexity and multifactorial nature of postmenopausal osteoporosis, further research is needed to investigate the possible synergistic effect of pharmacotherapy with certain exercise modalities, as highlighted in the study by Zhao et al. [29][46], who demonstrated that the combination of hormone replacement therapy (HRT) and a mixed-modality exercise protocol (high-impact activity in combination with high-intensity progressive muscle strengthening exercise was able to generate greater beneficial effects on hip and spine BMD in postmenopausal women than single-modality exercise.

Muscle strengthening exercise in postmenopausal women with OP produces favorable results in terms of bone mineral density, strength, functionality, and quality of life. However, the benefits produced can be increased when combined with other therapeutic exercise modalities such as aerobic, balance and coordination.
