Cuantificar los componentes de volumen e intensidad de la carga de entrenamiento es importante para garantizar la mejora del rendimiento. El objetivo de este estudio fue el comparar los efectos del volumen y la intensidad de la carga de entrenamiento sobre la Frecuencia Cardiaca de Recuperación (FCR). Dos mujeres y cuatro hombres, (edad M: 21 ± 1.41, H: 25.75 ± 4.57 años) entrenados en deportes de resistencia llevaron a cabo dos tratamientos con la misma carga interna (TRIMP = 52 unidades arbitrarias) pero con variación en volumen e intensidad (T1 = intensidad alta y volumen bajo [86-91% FCres, 14.5 min, T2 = intensidad baja y volumen alto [72-78% FCres, 30.5 min]). Posterior al ejercicio se monitoreó la FCR en cinco momentos: al finalizar el esfuerzo (R1), 10 (R2), 20 (R3), 30 (R4) y 40 (R5) minutos después del esfuerzo. Se encontraron diferencias significativas (p ≤ .05) entre los valores de FCR en los cinco momentos. Los resultados sugieren que tratamientos de la misma carga interna existen diferencias entre la carga interna de los tratamientos, observando que la intensidad afecta de mayor manera a la FCR que el volumen. Abstract. Quantifing the effects of volume and intensity components of training load (TL) is essential in order to guarantee performance enhancement. The aim of this study was to compare the effects of training load volume and intensity on Heart Rate Recovery (HRR). Two women (age = 21 ± 1.41) and four men (age = 25.75 ± 4.57 years) trained in endurance sports performed two different treatments with equal TL (TRIMP = 52 arbitrary units) but different volume and intensity (Training 1 = high intensity, low volume [86-91% HRres, 14.5 min], Training 2 = low intensity, high volume [72-78% HRres, 30.5 min]). HRR was monitored after exercise in five moments: at the end of training (R1), and 10 (R2), 20 (R3), 30 (R4), and 40 (R5) minutes after effort. Significant differences were found in HRR values at each of the five intervals (p ≤ .05). Results suggest the existence of significant differences in TL between the two treatments. Outcomes also evidenced that intensity has a greater effect than volume on HRR.

Abstract Background: The current study investigated the chronic effects of high-volume moderate-intensity training and low-volume high-intensity training on heart rate variability (HRV) and arterial stiffness in sedentary adult men. Materials and methods: Forty-five males (age: 42± 5.7 yrs.) were randomly assigned into control group (n=15), high-volume moderate-intensity training (HVMIT) (n=15), and low-volume high-intensity training (LVHIT) (n=15). The HVMIT group ran three times per week, on the treadmill at 50% to 60% of VO2max for 45 to 60 minutes, while the LVHIT trained at 70% to 85% of VO2max for 25 to 40 minutes. Both training programs were equated by caloric expenditure. HRV, Pulse Wave Velocity (PWV), hemodynamic variables, and body composition were measured before and after 12 weeks.Results: Both protocols (HVMIT and LVHIT) significantly increased the Standard deviation of NN intervals (SDNN) and High-frequency (HF) bands after 12 weeks (p ˂ 0.05). The LF/HF ratio decreased significantly in both training groups (p ˂ 0.05). However, these changes were significantly greater in the LVHIT protocol (p ˂ 0.05). Furthermore, the Root mean square of successive RR interval differences (RMSSD) significantly increased only in the LVHIT protocol (P ˂ 0.05). Moreover, a significant decrease in low-frequency (LF) and PWV was only observed following the LVHIT protocol (P ˂ 0.05). Conclusion: This study indicates that the LVHIT protocol is more effective and efficient for improving HRV variables and PWV than the HVMIT protocol.

Purpose: The aim of this study was to investigate the interaction of training load quantification using heart rate (HR) and rating of perceived exertion (RPE)-based methodology, and the relationship between internal training load parameters and subjective training status (Fatigue) in high-level rowers during volume increased low-intensity training period.Methods: Training data from 19 high-level rowers (age 23.5 ± 5.9 years; maximal oxygen uptake 58.9 ± 5.8 ml·min−1·kg−1) were collected during a 4-week volume increased training period. All individual training sessions were analyzed to quantify training intensity distribution based on the HR time-in-zone method (i.e., HR Z1, HR Z2, and HR Z3) determined by the first and second ventilatory thresholds (VT1/VT2). Internal training load was calculated using session RPE (sRPE) to categorize training load by effort (i.e., sRPE1, sRPE2, and sRPE3). The Recovery-Stress Questionnaire for Athletes (RESTQ-Sport) questionnaire was implemented after every week of the study period.Results: No differences were found between the respective HR and effort-based zone distributions during the baseline week (p > 0.05). Compared to HR Z1, sRPE1 was significantly lower in weeks 2–4 (p < 0.05), while sRPE2 was higher in weeks 2–3 compared to HR Z2 (p < 0.05) and, in week 4, the tendency (p = 0.06) of the higher amount of sRPE3 compared to HR Z3 was found. There were significant increases in RESTQ-Sport stress scales and decreases in recovery scales mostly during weeks 3 and 4. Increases in the Fatigue scale were associated with the amounts of sRPE2 and sRPE3 (p = 0.011 and p = 0.008, respectively), while no associations with Fatigue were found for HR-based session quantification with internal or external training load variables.Conclusion: During a low-intensity 4-week training period with increasing volume, RPE-based training quantification indicated a shift toward the harder rating of sessions with unchanged HR zone distributions. Moderate and Hard rated sessions were related to increases in Fatigue. Session rating of perceived exertion and effort-based training load could be practical measures in combination with HR to monitor adaptation during increased volume, low-intensity training period in endurance athletes.

The merits of low-volume high-intensity interval exercise (HIT) have been established in healthy populations; however, no studies have examined this exercise prescription in patients with coronary artery disease (CAD). The present thesis examined the acute and chronic effects of HIT in patients with CAD. The first study demonstrated transient improvements in brachial artery endothelial-dependent function, which was assessed using flow-mediated dilation (FMD) 60 min following a single bout of either HIT or moderate-intensity endurance exercise (END) in habitually active patients. The second study demonstrated no effects of training status on the acute endothelial responses to exercise; following 12-weeks of either HIT or END training. However, there was a significant reduction in endothelial-independent function immediately postexercise, at both pre- and post-training, which requires further examination. The third study demonstrated comparable increases in fitness and resting FMD following 12-weeks of END and HIT, lending support to the notion that favourable adaptations are obtainable with a smaller volume of exercise. Finally, the fourth study demonstrated no change in heart rate recovery following 12-weeks of END and HIT. However, pre-training heart rate recovery values reported by our sample were in a low risk range, which suggests training induced improvements may only be achievable in populations with attenuated pre-training values. The results of this thesis provide preliminary evidence that supports the use of HIT in patients with CAD. The findings of favourable transient and chronic improvements following HIT are notable, especially given that the HIT protocol involves less time and work than END, which was modelled after the current exercise prescription in cardiac rehabilitation. Further investigations are necessary, including the assessment of additional physiological indices; the feasibility and adherence to HIT; the inclusion of CAD populations with comorbidities, including heart failure and diabetes; as well as other forms of HIT training, including HIT combined with resistance training.
