“…Early studies have reported cardiac autonomic dysfunction and low HRV in patients with obesity, as indicated by the downregulation of vagal tone and sympathetic overactivity [ 5 , 28 , 29 ]. On the other hand, weight loss through lifestyle changes [ 30 ] or BS has improved HRV parameters [ 16 ]. This benefit is more pronounced in individuals with a weight loss of about 10% and is considered to be the main cause of increased parasympathetic modulation and decreased sympathetic modulation [ 16 , 30 , 31 ].…”

Objectives: Investigate changes in blood pressure (BP) and heart rate variability (HRV) in women with and without sarcopenia-related parameters who underwent bariatric surgery (BS) during a one-year follow-up. Subjects and Methods: Women were separated into obesity (OB, n = 20) and women with obesity displaying sarcopenia-related parameters (SOP, n = 14) and evaluated before BS and 3, 6, and 12 months after BS. SOP was defined as low handgrip strength (HS) and/or low appendicular skeletal mass adjusted for weight (ASM/wt × 100, %) in the lowest quartile of the sample. ASM/wt × 100, % and HS were significantly lower in SOP than OB over a one-year follow-up of BS (p < 0.05). Results: There was a reduction in diastolic BP, heart rate (HR), SDHR, LF, and the LF/HF ratio (p < 0.05) and an increase in the HF band in both groups during the follow-up period (p < 0.05). SOP women had reduced root mean square differences of successive RR intervals (RMSSD) and HF band and an increased LF band and SD2/SD1 ratio compared to the OB group during the one-year follow-up (p < 0.05). ASM/wt × 100, % was negatively associated with the LF band (r = −0.24, p = 0.00) and positively associated with the HF band (r = 0.22, p = 0.01). Conversely, HS had no association with LF (r = −0.14, p = 0.09) and HF (r = 0.11, p = 0.19). ASM/wt × 100, % and HS were negatively associated with the LF/HF ratio (p < 0.05). Conclusions: Women who underwent BS had an improved HRV over a one-year follow-up. However, the improvement in HRV variables was less pronounced in women with low muscle mass and/or HS during the follow-up period.

“…Increased age [ 74 ]; male sex [ 74 ]; increased BMI [ 74 ]; poor sleep time and quality [ 75 ]; stress [ 9 ] and anticipation of a stressful event [ 76 ]; consumption of alcohol and/or nicotine [ 77 , 78 ]; dehydration [ 79 ]; acute sickness [ 80 ]; post-vaccination symptomatology [ 81 ]; acute and chronic pain [ 82 , 83 , 84 ]; concussion and post-concussion recovery [ 85 , 86 , 87 ]; travel or training camps [ 8 , 51 ]; medications including but not limited to beta-blockers [ 88 ], angiotensin-converting enzyme inhibitors [ 89 ], contraceptive medications [ 90 ], and antidepressants [ 91 ]; and many psychiatric and physiological diseases [ 91 , 92 ] can be associated with a reduced HRV. Weight loss in overweight and obese individuals is associated with an improved HRV from their original baseline [ 93 ]. Additionally, HRV often varies in a predictable pattern associated with the female menstrual cycle [ 94 , 95 ] and may be related to factors that influence training, such as sleep quality, stress, injury, motivation, and program enjoyment [ 96 ].…”

Heart rate variability (HRV) is defined as the fluctuation of time intervals between adjacent heartbeats and is commonly used as a surrogate measure of autonomic function. HRV has become an increasingly measured variable by wearable technology for use in fitness and sport applications. However, with its increased use, a gap has arisen between the research and the application of this technology in strength and conditioning. The goal of this narrative literature review is to discuss current evidence and propose preliminary guidelines regarding the application of HRV in strength and conditioning. A literature review was conducted searching for HRV and strength and conditioning, aiming to focus on studies with time-domain measurements. Studies suggest that HRV is a helpful metric to assess training status, adaptability, and recovery after a training program. Although reduced HRV may be a sign of overreaching and/or overtraining syndrome, it may not be a sensitive marker in aerobic-trained athletes and therefore has different utilities for different athletic populations. There is likely utility to HRV-guided programming compared to predefined programming in several types of training. Evidence-based preliminary guidelines for the application of HRV in strength and conditioning are discussed. This is an evolving area of research, and more data are needed to evaluate the best practices for applying HRV in strength and conditioning.

“…Direct comparison obesity treatment effects on pulse/heart rate also presents challenges due to lack of comprehensive head-to-head clinical data, especially long-term clinical data. While weight reduction via healthful nutrition and physical activity seems to consistently improve heart rate variability [ 156 ], the reports of the effects of caloric restriction on heart rate are more variable, with results most often favoring a reduction in heart rate [ 157 , 158 ]. Both low energy diets and very low energy diets generally decrease heart rate (and decrease blood pressure) [ 159 ].…”
