Changes in heart rate recovery after high-intensity training in well-trained cyclists

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.

Aim: Soccer is characterized as an intense intermittent team sport. Heart rate (HR) is used to monitor the players’ training response, as well as to quantify microcycle and mesocycle training intensity during preseason and in-season periods. The purpose of the present study was to quantify the preseason training intensity distribution in elite soccer players and then examine the relationship between HR distribution and changes in aerobic fitness. Material & Method: Sixteen elite professional soccer players (age, 26.8 ± 3.8 years; weight, 77.8 ± 7.7 kg; height, 1.79 ± 0.06 m; mean ± SD) participated in the study. Aerobic fitness was evaluated with VO2max, running velocity at VO2max (v-VO2max) during a laboratory incremental aerobic test and with the distance completed during an interval shuttle run test (ISRT), before and after preseason. HR of each player was measured using a short-range telemetry HR transmitter strap at 5-s intervals during all training sessions of the preseason. The absolute (min) and relative (%) time spent in high-intensity HR zone (90–100% of HRmax) during the preseason period was calculated for each player. Results: VO2max and distances completed during ISRT improved significantly (p < 0.05) by 3.3 ± 2.1% and 29 ± 16%, respectively. The time (%) players spent in high-intensity training was significantly correlated (p < 0.01) with the changes (%) in distance completed during ISRT. Conclusions: These results provide useful information about the HR quantification during preseason in elite soccer players. Additionally, coaches have to take into consideration the time soccer players spend in high-intensity training for optimal endurance responses when planning and implementing the preseason training period.

Intensity Training

Research on heart rate (HR), mean arterial pressure (MAP) and blood pressure (BP) during specific training stages is less common in endurance athletes, whereas resting BP and HR are less studied in relationship to HRmax. In the current study, the objective was to conduct a medium-term HR, BP and MAP analysis while tracking individual training outcomes. The study was conducted during the 2017–2018 season, over 43 days and 1033 km of training volume, on 12 competitive male cross-country ski athletes. One VO2max test was performed 10 days before the start of the training program. After the test, training volume and intensity was preset for each subject, according to the general training methodology. Early morning HR, MAP and BP measurements were taken as part of the basic functional analysis. Training volume was correlated to both distance (p = 0.01, r = 0.85, CI95% = 0.80 to 0.88) and training HR%, namely the percentage of HRmax (p = 0.01, r = −0.47, CI95% = −0.58 to −0.34). Both the supine (sHR) and orthostatic HR (oHR) values were significantly correlated with the training intensity. We obtained a significant correlation between sHR and oHR values and the training objective (p = 0.01). An increased oHR was correlated to high intensity training activity (HIT) during the second training session (p = 0.01). Heart rate and blood pressure measurements represent predictive functional adaptation parameters over different training phases. We highlight a link between sHR, oHR, MAP data, and the athletes’ ability to perform in lower effort zones during physical exertion. However, we failed to validate MAP as a cardiovascular stress indicator following high intensity training.

Purpose:To determine whether a submaximal cycling test could be used to monitor and prescribe high-intensity interval training (HIT).Methods:Two groups of male cyclists completed 4 HIT sessions over a 2-wk period. The structured-training group (SG; n = 8, VO2max = 58.4 ± 4.2 mL · min−1 · kg−1) followed a predetermined training program while the flexible-training group (FG; n = 7, VO2max = 53.9 ± 5.0 mL · min−1 · kg−1) had the timing of their HIT sessions prescribed based on the data of the Lamberts and Lambert Submaximal Cycle Test (LSCT).Results:Effect-size calculations showed large differences in the improvements in 40-km time-trial performance after the HIT training between SG (8 ± 45 s) and FG (48 ± 42 s). Heart-rate recovery, monitored during the study, tended to increase in FG and remain unchanged in SG.Conclusions:The results of the current study suggest that the LSCT may be a useful tool for coaches to monitor and prescribe HIT.

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.
