Abstract
The negative impact of loneliness on the health of the elderly is particularly noticeable because of the effects of central control on the autonomic nervous system. Such an impact can be assessed through heart rate variability (HRV) analysis and can be modified using HRV biofeedback training. This study aimed to investigate the impact of different levels of social interaction reported by the elderly on HRV before and after training with HRV biofeedback and after a follow-up period. The participants of this pilot study comprised 16 elderly people of both sexes with a mean age of 71.20 ± 4.92 years. The participants were divided into two groups, the loneliness group (N = 8) and the no-loneliness group (N = 8), based on a combination of both criteria: the institutionalization condition (institutionalized or not) and the score on the loneliness scale (high or low). All participants had their HRV components recorded at baseline, after 14 training sessions with HRV biofeedback (three times a week, 15 min each for 4.5 weeks), and after 4.5 weeks of follow-up without training. After HRV biofeedback training, HRV components increased in both groups. However, the gains lasted at follow-up only in the no-loneliness group. In conclusion, loneliness can influence the maintenance of HRV after interruption of training with HRV biofeedback in the elderly. HRV biofeedback training can be an innovative and effective tool for complementary treatment of elderly individuals, but its effects on lonely elderly individuals need to be further investigated.

Abstract
Gamma-aminobutyric acid (GABA) serves as a pivotal neurotransmitter implicated in the pathogenesis of stress, anxiety, sleep-related disorders, and heart rate (HR) reactions. Heart-rate variability (HRV), modulated by the sympathetic and parasympathetic branches of the autonomic nervous system (ANS), offers insights into cardiac autonomic control and cardiovascular well-being. The present study aimed to explore the impact of GABA supplementation on emotional metrics, sleep quality, and HRV in sedentary women with overweight or obesity partaking in physical exercise. A randomized, double-blind, placebo-controlled clinical trial was undertaken involving 30 sedentary women with overweight or obesity. Volunteers were assigned randomly to two groups: the intervention group receiving GABA (200 mg) once daily for a total of 90 supplementation doses, and the placebo group. Both groups engaged in physical exercise, while the supplementation regimen spanned 90 days. Assessments were conducted at three intervals: baseline (T0), midway through the study (T45), and study culmination (T90). Following 90 days of GABA supplementation, the intervention group demonstrated enhancements in habitual sleep efficiency, as indicated by reductions in Pittsburgh Sleep Quality Index (PSQI) scores. Moreover, an improved emotional response was observed, characterized by diminished negative affect. GABA supplementation yielded ameliorations in depression scores as per the Depression, Anxiety, and Stress Scale (DASS-21). Notably, an augmented HRV was noted, attributed to heightened parasympathetic autonomic nervous system predominance. GABA supplementation elicited noteworthy enhancements in heart rate variability, emotional response, depression mitigation, and sleep efficiency following a 90-day supplementation.

Abstract
Heart rate variability is a non-invasive method of assessing global health through the analysis of the autonomous centralnervous system, including both the sympathetic and parasympathetic systems. The aim of this study was to evaluate the effect of resistance training on heart rate variability at rest in elderly individuals undergoing six months of resistance training with progressive loads. Training reduced the body fat percentage of the volunteers (pre: 39.39 ± 7.21 vs post: 34.97 ± 6.40%; p = 0.0069). There was also a significant reduction in the low-frequency index (pre: 69621.50 ± 9817.28 vs post: 54210.50 ± 14903.94; p = 0.0322) and a significant increase in the high-frequency index (pre: 30308.00 ± 9857.86 vs post: 45627.10 ± 14838.80; p = 0.0326). We concluded that sixmonths of resistance training with progressive loads were beneficial for heart rate variability and reduced the body fat percentage in the elderly.

Abstract
INTRODUCTION The intake of sugar-sweetened beverages (SSBs) has increased rapidly, but the effects of this habit on health and physical performance are unknown. This study assessed the effect of excessive SSB intake on biochemical, physical performance, and biochemical and cardiovascular parameters of physically active males. METHODS Seventeen volunteers consumed a placebo drink (Pd; carbohydrate free) and an excessive SSB drink (eSSBd = Pd plus 300 g sucrose). In a blind randomized crossover study, the subjects were assigned to Pd or eSSBd groups for 15 days. After an interval of 7 days, subjects were reassigned to the other condition. RESULTS After eSSBd intake, there was an increase in weight (69.34 ± 13.71 vs. 70.62 ± 14.06), body mass index (24.49 ± 4.01 vs. 24.97 ± 4.13), waist circumference (75.33 ± 11.22 vs. 76.79 ± 11.51), VLDL (19.54 ± 9.50 vs. 25.52 ± 11.18), triglycerides (78.94 ± 23.79 vs. 114.77 ± 43.65), and peak systolic blood pressure (178.57 ± 26.56 vs. 200.71 ± 24.64). The cardiorespiratory response to exercise (VO2max) (48.15 ± 10.42 vs. 40.98 ± 11.20), peak heart rate (186.64 ± 8.00 vs. 179.64 ± 6.28), total exercise time (15.02 ± 1.57 vs. 14.00 ± 2.18), and mechanical work (15.83 ± 4.53 vs. 13.68 ± 5.67) decreased after eSSBd intake (all values expressed in initial mean ± DP vs. final). The rates of perceived exertion were higher (1.300 vs.1.661 slope and -0.7186 vs. -1.118 y-intercept) after eSSBd intake. CONCLUSION The present study shows that 15 days of eSSBd intake may negatively modulate biochemical parameters associated with cardiovascular risk. In addition, this overintake can impair the physical performance and cardiovascular responses to physical exercise.
