## 1 Introduction
The functionality of the pelvic floor is critically dependent on both muscle tone and strength, each contributing uniquely to overall urogenital health [15]. Muscle tone refers to the continuous and involuntary contraction of the muscles, which is essential for maintaining posture and ensuring the stability of pelvic organs. Conversely, muscle strength pertains to the active capacity of the muscles to overcome a resistance during voluntary contractions, playing a pivotal role in activities requiring increased intra-abdominal pressure, such as coughing, lifting, jumping, and athletic endeavors [16]. Enhancing PFM strength has been shown to effectively improve pelvic floor dysfunctions, particularly UI. A systematic review by [PERSON] et al. [17] demonstrated that PFM training, both with and without adjuncts like biofeedback or electrostimulation, significantly reduced UI symptoms and enhanced PFM contraction in non-pregnant women. Specifically, 62% of participants experienced a notable reduction or complete resolution of UI, accompanied by improved PFM strength. These findings underscore the critical role of targeted muscle strengthening in restoring pelvic floor functionality and alleviating associated dysfunctions. At the same time, load absorption and muscle efficiency are key parameters in assessing pelvic floor muscle (PFM) functionality. Load absorption refers to the pelvic floor's ability to withstand and distribute intra-abdominal pressure changes effectively, preventing excessive strain on the musculature and surrounding structures. This is particularly relevant during activities that increase intra-abdominal pressure, as mentioned above (coughing, lifting, or physical exertion) [3]. Muscle efficiency, on the other hand, represents the ability of the PFMs to generate force with minimal energy expenditure, ensuring sustained contraction without early fatigue [3]. AHT is proposed to enhance these parameters through a combination of diaphragmatic aspiration, postural adjustments, and deep core muscle activation. The vacuum effect created by AHT induces reflexive co-activation of the transverse abdominis and PFMs, which may improve load absorption by optimizing the pressure distribution within the abdominopelvic cavity [4]. Additionally, repeated exposure to AHT postures and breathing patterns may enhance neuromuscular coordination and proprioception, leading to greater muscle efficiency over time. Studies have suggested that integrating hypoppressive exercises (HE) into rehabilitation protocols can improve endurance and responsiveness of the PFMs, reducing functional impairments such as stress urinary incontinence and pelvic organ prolapse [5; 7]. For all women, it is essential to have the pelvic floor and abdominal muscles in good condition to have maximum functionality. This situation is particularly interesting for female athletes. In the context of athletic performance, optimal pelvic floor muscle function is indispensable [18]. Adequate muscle tone provides the necessary support to pelvic organs, preventing conditions like urinary incontinence during high-impact activities [19]. Simultaneously, robust muscle strength enhances core stability and facilitates efficient force transmission between the upper and lower body, thereby improving coordination and power output [20]. Strength, complementary to tone, offers a dynamic perspective of muscular capacity, measured during maximum voluntary isometric contraction (MVIC) held over a defined duration. This approach facilitates a comprehensive understanding of the intervention's impact on both peak and sustained force generation [21]. Distinguishing between tone and strength is crucial, as imbalances can lead to dysfunction. Hypertonicity, or excessive muscle tone, may result in pelvic pain and impede muscle relaxation [22], while hypotonicity can compromise support and continence mechanisms [23].
