“…In order to evaluate the programs in this study, we checked the HR, as it is an essential indicator to assess the effects of exercise in humans [27,28]. It is a noninvasive method, which can indicate the clinical status of the cardiac function and presence/absence of cardiovascular diseases in exercise studies [23].…”

Although proper exercise training induces positive physiological effects, improper exercise can lead to injury, fatigue, and poor performance. The frequency, intensity, time/duration, type, volume, and progression (FITT-VP) are the essential components of exercise training to maintain or improve physical fitness and health. The purpose of this study was to develop specific exercise programs by applying the FITT-VP principle and to examine the effects on heart rate (HR) and hematological and biochemical parameters in dogs. The healthy male Beagles (n = 4) included in this study performed continuous and interval exercises, comprising 12 protocols. The HR monitoring elicited an affirmative response to activities but varied depending on the protocols. The hematologic parameters (e.g., red blood cell count, white blood cell count, hemoglobin, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration) were within the reference ranges both before and after exercise. The creatine kinase level significantly increased, and the cholesterol level decreased after exercises. In conclusion, the continuous and interval exercise program elicits an appropriate HR reaction, has no adverse effects on the serum parameters, and provides valuable insight for healthcare in dogs.

Blood pressure (Bp) is a cardiovascular parameter applied to detect cardiovascular risk. Recently, the pre-hypertension state has received greater consideration for prevention strategies. We evaluated autonomic and cardiorespiratory recovery following aerobic exercise in normotensive individuals with different systolic BP (SBP) values. We investigated 30 healthy men aged 18 to 30 years divided into groups according to systolic BP (SBP): G1 (n = 16), resting SBP <110 mmHg and G2 (n = 14), resting SBP between 120-110 mmHg. The groups endured 15 minutes seated at rest, followed by a submaximal aerobic exercise on a treadmill and then remaining seated for 60 minutes also at rest, during recovery from the exercise. Cardiorespiratory parameters and heart rate (HR) variability (HRV) (rMSSD, SD1, HF [ms 2 ]) were evaluated before and during recovery from exercise. G2 displayed slower return of SBP, rMSSD and SD1 HRV indices during recovery from exercise compared to G1. In conclusion, normotensive subjects with higher resting SBP (110 to 120 mmHg) offered delayed autonomic recovery following moderate exercise. We suggest that this group may be less physiologically optimized leading to cardiac risks. Cardiovascular diseases are the foremost cause of mortality worldwide 1. Studies in humans and animals have demonstrated that autonomic dysfunction is closely related to cardiovascular diseases, since autonomic dysfunction implies an inferior prognosis for individuals, increasing the risk of cardiac arrest, infarctions and sudden death 2-4. Hence, a non-invasive method that evaluates autonomic modulation is heart rate (HR) variability (HRV). It defines the oscillations between consecutive inter-beat intervals (IBI) that are related to the influence of the autonomic nervous system on the sinus node of the heart 5. HRV is reduced in hypertension 6 , which is a significant risk factor for the development of cardiovascular disorders and the chief reason of premature death 1,7. Approximately, one billion people globally are hypertensive and more vulnerable to stroke and sudden death 1,7. So, due to the hazardous control of blood pressure (BP) levels in the hypertensive population, there is an increase in cardiovascular morbidity and mortality 8. According to the most recent guidelines for the management of hypertension, BP is classified as normal for systolic BP (SBP) <120 mmHg and diastolic BP (DBP) <80 mmHg); pre-hypertension for SBP between 129 and 139 mmHg and/or DBP between 80 and 89 mmHg; stage 1 hypertension for SBP between 140 and 159 mmHg and/or DBP between 90 and 99 mmHg and; stage 2 hypertension for SBP values ≥160 mmHg and/or DBP ≥100 mmHg 9. Pre-hypertension was formerly indicated to be a risk factor for cardiovascular disease 10. Guo et al. 10 commenced a systematic review and meta-analysis of prospective studies to evaluate the connection between pre-hypertension and cardiovascular disorders. The authors considered pre-hypertension or high normal BP as baseline exposure, fatal or non-fatal incident stroke, myocardial...

23Birth weight (BW) can be used to assess the health status of the newborn. However, its impacts 24 on later in life regarding heart rate (HR) variability (HRV) is not totally clear. We aimed to 25 analyze the involvement of BW and body composition on HRV recovery following aerobic 26 exercise in children. The study was conducted in healthy children 9 to 11 years of age (40 27 females and 27 males) divided into two groups: G1 (BW < 3400 grams, N = 33) and G2 (BW > 28 3400 grams, N = 34). The volunteers completed an experimental protocol of submaximal aerobic 29 exercise on a treadmill and remained seated for 30 minutes after exercise. Systolic (SAP) and 30 diastolic arterial pressure (DAP), respiratory rate (f) and HRV were analyzed before and during 31 recovery from exercise. SAP and f were significantly decreased 30 minutes after exercise 32 compared to 1 minute after exercise in G1 and G2. Mean HR, high frequency band of spectral 33 analysis (HF) , root mean square of successive interbeat intervals difference, SD1 index and 34 mean lenght were diminished 0 to 5 minutes after exercise compared to rest in G2 while 35 maximum lenght increased 0 to 5 minutes after exercise compared to resting in G2. Linear 36 regression revealed association of fat percentage and BW with nonlinear HRV recovery. In 37 conclusion, autonomic recovery after exercise was somewhat delayed in children with high BW. 38 BW and fat percentage slightly influence HRV recovery. 39 40
