Abstract Purpose The current study sought to investigate the role of recovery intensity on the physiological and perceptual responses during cycling-based aerobic high-intensity interval training. Methods Fourteen well-trained cyclists ($$\dot{V}{\text{O}}_{{{\text{2peak}}}}$$ V ˙ O 2peak : 62 ± 9 mL kg−1 min−1) completed seven laboratory visits. At visit 1, the participants’ peak oxygen consumption ($$\dot{V}{\text{O}}_{{{\text{2peak}}}}$$ V ˙ O 2peak ) and lactate thresholds were determined. At visits 2–7, participants completed either a 6 × 4 min or 3 × 8 min high-intensity interval training (HIIT) protocol with one of three recovery intensity prescriptions: passive (PA) recovery, active recovery at 80% of lactate threshold (80A) or active recovery at 110% of lactate threshold (110A). Results The time spent at > 80%, > 90% and > 95% of maximal minute power during the work intervals was significantly increased with PA recovery, when compared to both 80A and 110A, during both HIIT protocols (all P ≤ 0.001). However, recovery intensity had no effect on the time spent at > 90% $$\dot{V}{\text{O}}_{{{\text{2peak}}}}$$ V ˙ O 2peak (P = 0.11) or > 95% $$\dot{V}{\text{O}}_{{{\text{2peak}}}}$$ V ˙ O 2peak (P = 0.50) during the work intervals of both HIIT protocols. Session RPE was significantly higher following the 110A recovery, when compared to the PA and 80A recovery during both HIIT protocols (P < 0.001). Conclusion Passive recovery facilitates a higher work interval PO and similar internal stress for a lower sRPE when compared to active recovery and therefore may be the efficacious recovery intensity prescription.

The current study sought to explore the incidence of nonresponders for maximal or submaximal performance following a variety of sprint interval training (SIT) protocols. Data from 63 young adults from 5 previously published studies were utilized in the current analysis. Nonresponders were identified using 2 times the typical error (TE) of measurement for peak oxygen uptake (2 × TE = 1.74 mL/(kg·min)), lactate threshold (2 × TE = 15.7 W), or 500 kcal time-to-completion (TTC; 2 × TE = 306 s) trial. TE was determined on separate groups of participants by calculating the test–retest variance for each outcome. The overall rate of nonresponders for peak oxygen uptake across all participants studied was 22% (14/63) with 4 adverse responders observed. No nonresponders for peak oxygen uptake were observed in studies where participants trained 4 times per week (n = 18), while higher rates were observed in most studies requiring training 3 times per week (30%–50%; n = 45). A nonresponse rate of 44% (8/18) and 50% (11/22) was observed for the TTC test and lactate threshold, respectively. No significant correlations were observed between the changes in peak oxygen uptake and TTC (r = 0.014; p = 0.96) or lactate threshold (r = 0.17; p = 0.44). The current analysis demonstrates a significant incidence of nonresponders for peak oxygen uptake and heterogeneity in the individual patterns of response following SIT. Additionally, these data support the importance of training dose and suggest that the incidence of nonresponse may be mitigated by utilizing the optimal dose of SIT.

Penelitian ini bertujuan untuk menguji pengaruh dari dua bentuk latihan interval terhadap lactate threshold (LT) dan waktu tempuh lari 1500 m. Metode penelitian yang digunakan adalah kuasi eksperimen. yang dilakukan melalui teknik sampling jenuh. 12 pelari remaja (6 putra dan 6 putri) dikelompokkan secara matching. Kelompok latihan interval melakukan fast interval training (FIT) dengan durasi 30 detik, dengan 4-5 pengulangan dan 4 menit istirahat. Intensitas Average 1500m running velocity sebesar 120% AV. Sedangkan kelompok latihan interval melakukan slow interval training (SIT) dengan durasi ≥ 2 menit. Pengulangan dilakukan sebanyak 6-10, dan 3 menit istirahat pada intensitas 110% dari LT. Data penelitian diperoleh melalui the modified conconi test dan tes lari 1500 m. Hasil pengolahan dan analisis data menunjukkan ada perbedaan yang signifikan antara SIT dan FIT terhadap LT (p=0.029) dan waktu tempuh lari 1500 m (p=0.004). LT berkorelasi dengan waktu tempuh lari 1500 m pada kedua kelompok latihan, yaitu SIT (r =-0.942) dan FIT (r = -0.942). Temuan pada penelitian ini menunjukkan bahwa SIT memberikan pengaruh yang lebih besar terhadap LT dan waktu tempuh lari 1500m dibandingkan dengan FIT. Dengan demikian, dapat disimpulkan bahwa SIT merupakan strategi yang efektif dan efisien dalam meningkatkan LT dan memperbaiki waktu tempuh lari 1500 m untuk periode latihan selama 4 minggu.

Purpose:Several recent studies have reported substantial performance and physiological gains in well-trained endurance runners, swimmers, and cyclists following a period of high-intensity interval training (HIT). The aim of the current study was to compare traditional rowing training (CT) to HIT in well-trained rowers.Methods:Subjects included 5 male and 5 female rowers (mean ± SD; age = 19 ± 2 y; height = 176 ± 8 cm; mass = 73.7 ± 9.8 kg; Vo2peak = 4.37 ± 1.08 L·min−1). Baseline testing included a 2000-m time trial and a maximal exercise test to determine Vo2peak, 4-min all-out power, and 4 mmol·L−1 blood lactate threshold. Following baseline testing, rowers were randomly allocated to HIT or CT, which they performed seven times over a 4-wk period. The HIT involved 8 × 2.5-min intervals at 90% of the velocity maintained at Vo2peak, with individual recoveries returning to 70% of the subjects’ maximal heart rate between intervals. The CT intensity consisted of workloads corresponding to 2 and 3 mmol·L−1 blood lactate concentrations. On completion of HIT or CT, rowers repeated the testing performed at baseline and were then allocated to the alternative training program and completed a crossover trial.Results:HIT produced greater improvements in 2000-m time (1.9 ± 0.9%; mean ± SD), 2000-m power (5.8 ± 3.0%), and relative Vo2peak (7.0 ± 6.4%) than CT.Conclusion:Four weeks of HIT improves 2000-m time-trial performance and relative Vo2peak in competitive rowers, more than a traditional approach.

This study determined the effects of altering the H+ concentration during interval training, by ingesting NaHCO3 (Alk-T) or a placebo (Pla-T), on changes in muscle buffer capacity (βm), endurance performance, and muscle metabolites. Pre- and posttraining peak O2 uptake (V̇o2 peak), lactate threshold (LT), and time to fatigue at 100% pretraining V̇o2 peak intensity were assessed in 16 recreationally active women. Subjects were matched on the LT, were randomly placed into the Alk-T ( n = 8) or Pla-T ( n = 8) groups, and performed 8 wk (3 days/wk) of six to twelve 2-min cycle intervals at 140–170% of their LT, ingesting NaHCO3 or a placebo before each training session (work matched between groups). Both groups had improvements in βm (19 vs. 9%; P < 0.05) and V̇o2 peak (22 vs. 17%; P < 0.05) after the training period, with no differences between groups. There was a significant correlation between pretraining βm and percent change in βm ( r = −0.70, P < 0.05). There were greater improvements in both the LT (26 vs. 15%; P = 0.05) and time to fatigue (164 vs. 123%; P = 0.05) after Alk-T, compared with Pla-T. There were no changes to pre- or postexercise ATP, phosphocreatine, creatine, and intracellular lactate concentrations, or pHi after training. Our findings suggest that training intensity, rather than the accumulation of H+ during training, may be more important to improvements in βm. The group ingesting NaHCO3 before each training session had larger improvements in the LT and endurance performance, possibly because of a reduced metabolic acidosis during training and a greater improvement in muscle oxidative capacity.
