| Abstract (English): | Objective: To describe the relationship between heart rate variability (HRV) parameters and body composition in female athletes training at high southern latitudes. Material and Methods: A cross-sectional observational study with a correlational design was conducted. Thirty-one female athletes participated, including 10 rugby players and 21 volleyball players from the Magallanes and Chilean Antarctic Region. Body composition was assessed using bioelectrical impedance analysis with a Tanita BC-558 device. HRV was recorded at rest using a Polar H10 chest strap and analyzed in the time and frequency domains with Kubios HRV software. RMSSD, SDNN, HF, LF, VLF, PNS/SNS indices, and a stress index were calculated. Spearman’s correlation coefficient was used to assess associations. Results: SDNN showed positive associations with muscle mass (r = 0.503, p < 0.01) and bone mass (r = 0.486, p < 0.01). RMSSD was associated with muscle mass (r = 0.408, p < 0.05). HF and LF showed moderate positive correlations with muscle mass (HF: r = 0.358, p < 0.05; LF: r = 0.450, p < 0.05). The PNS index was positively correlated with muscle mass (r = 0.423, p < 0.05) and bone mass (r = 0.403, p < 0.05). In contrast, the SNS index and stress index were negatively associated with muscle mass (SNS: r = −0.475, p < 0.01; stress: r = −0.559, p < 0.01) and bone mass (SNS: r = −0.466, p < 0.01; stress: r = −0.551, p < 0.01). Conclusion: In this sample of 31 female athletes, greater muscle and bone mass were associated with a more pronounced autonomic profile toward parasympathetic activity, as reflected by RMSSD, SDNN, HF, and the PNS index. Conversely, higher sympathetic and stress indices were associated with lower muscle and bone mass values. These findings suggest that body composition, particularly muscle and bone mass, is linked to autonomic modulation in female athletes training in high-latitude environments. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Objetivo: Describir la relación entre parámetros de variabilidad de la frecuencia cardíaca (VFC) y composición corporal en mujeres deportistas que entrenan en alta latitud sur. Material y Métodos: Estudio observacional transversal con alcance correlacional. Participaron 31 deportistas femeninas (10 de rugby y 21 de voleibol) de la región de Magallanes y Antártica Chilena. Las mediciones consistieron en composición corporal mediante bioimpedancia (Tanita BC-558). VFC registrada con una banda polar H10 en reposo, analizada en dominio temporal y frecuencia con Kubios HRV. Se calculó RMSSD, SDNN, HF, LF, VLF, índices PNS/SNS y un índice de stress. Se usó correlación de Spearman para evaluar asociaciones. Resultados: SDNN mostró asociación positiva con masa muscular (r = 0.503, p < 0.01) y masa ósea (r = 0.486, p < 0.01). RMSSD se asoció con masa muscular (r = 0.408, p < 0.05). HF y LF presentaron correlaciones positivas moderadas con masa muscular (HF r = 0.358, p < 0.05; LF r = 0.450, p < 0.05). El índice PNS correlacionó positivamente con masa muscular (r = 0.423, p < 0.05) y masa ósea (r = 0.403, p < 0.05). En contraste, el índice SNS y el índice de stress se asociaron negativamente con masa muscular (SNS r = -0.475, p < 0.01; stress r = -0.559, p < 0.01) y con masa ósea (SNS r = -0.466, p < 0.01; stress r = -0.551, p < 0.01). Conclusión: En esta muestra de 31 mujeres deportistas, mayor masa muscular y masa ósea se relacionaron con un perfil autonómico más marcado hacia la actividad parasimpática (RMSSD, SDNN, HF, índice PNS), mientras que mayores valores de los índices simpáticos y de stress se asociaron con menores valores de masa muscular y ósea. Estos resultados sugieren que la composición corporal, sobre todo masa muscular y ósea, está vinculada a la modulación autonómica en deportistas femeninas en ambientes de alta latitud.

| Abstract (Portuguese): | Objetivo: Descrever a relação entre os parâmetros da variabilidade da frequência cardíaca (VFC) e a composição corporal em mulheres atletas que treinam em altas latitudes do hemisfério sul. Material e Métodos: Estudo observacional transversal, de caráter correlacional. Participaram 31 atletas do sexo feminino, sendo 10 jogadoras de rugby e 21 de voleibol, da Região de Magalhães e da Antártica Chilena. A composição corporal foi avaliada por bioimpedância elétrica utilizando o equipamento Tanita BC-558. A VFC foi registrada em repouso com uma cinta Polar H10 e analisada nos domínios do tempo e da frequência por meio do software Kubios HRV. Foram calculados os índices RMSSD, SDNN, HF, LF, VLF, os índices PNS/SNS e um índice de estresse. A correlação de Spearman foi utilizada para avaliar as associações. Resultados: O SDNN apresentou associação positiva com a massa muscular (r = 0,503; p < 0,01) e a massa óssea (r = 0,486; p < 0,01). O RMSSD associou-se à massa muscular (r = 0,408; p < 0,05). HF e LF apresentaram correlações positivas moderadas com a massa muscular (HF: r = 0,358; p < 0,05; LF: r = 0,450; p < 0,05). O índice PNS correlacionou-se positivamente com a massa muscular (r = 0,423; p < 0,05) e a massa óssea (r = 0,403; p < 0,05). Em contraste, o índice SNS e o índice de estresse associaram-se negativamente à massa muscular (SNS: r = −0,475; p < 0,01; estresse: r = −0,559; p < 0,01) e à massa óssea (SNS: r = −0,466; p < 0,01; estresse: r = −0,551; p < 0,01). Conclusão: Nesta amostra de 31 mulheres atletas, maiores valores de massa muscular e massa óssea estiveram relacionados a um perfil autonômico mais acentuadamente orientado para a atividade parassimpática, refletido pelos índices RMSSD, SDNN, HF e PNS. Por outro lado, maiores valores dos índices simpático e de estresse associaram-se a menores valores de massa muscular e óssea. Esses resultados sugerem que a composição corporal, especialmente a massa muscular e a massa óssea, está relacionada à modulação autonômica em atletas do sexo feminino que treinam em ambientes de alta latitude.
