TLDR
Data demonstrate that SIT is a time‐efficient strategy to induce rapid adaptations in skeletal muscle and exercise performance that are comparable to ET in young active men.Abstract:
Brief, intense exercise training may induce metabolic and performance adaptations comparable to traditional endurance training. However, no study has directly compared these diverse training strategies in a standardized manner. We therefore examined changes in exercise capacity and molecular and cellular adaptations in skeletal muscle after low volume sprint-interval training (SIT) and high volume endurance training (ET). Sixteen active men (21 +/- 1 years, ) were assigned to a SIT or ET group (n = 8 each) and performed six training sessions over 14 days. Each session consisted of either four to six repeats of 30 s 'all out' cycling at approximately 250% with 4 min recovery (SIT) or 90-120 min continuous cycling at approximately 65% (ET). Training time commitment over 2 weeks was approximately 2.5 h for SIT and approximately 10.5 h for ET, and total training volume was approximately 90% lower for SIT versus ET ( approximately 630 versus approximately 6500 kJ). Training decreased the time required to complete 50 and 750 kJ cycling time trials, with no difference between groups (main effects, P </= 0.05). Biopsy samples obtained before and after training revealed similar increases in muscle oxidative capacity, as reflected by the maximal activity of cytochrome c oxidase (COX) and COX subunits II and IV protein content (main effects, P </= 0.05), but COX II and IV mRNAs were unchanged. Training-induced increases in muscle buffering capacity and glycogen content were also similar between groups (main effects, P </= 0.05). Given the large difference in training volume, these data demonstrate that SIT is a time-efficient strategy to induce rapid adaptations in skeletal muscle and exercise performance that are comparable to ET in young active men.read more

Intensity training and cardiovascular health in Colombian adults: results from HIIT-Heart Study and Cardiometabolic HIIT-RT Study
TL;DR: This doctoral thesis aimed to investigate whether 12 weeks of high-intensity interval training (HIIT), resistance training (RT), concurrent training (CT=HIII+RT) or nutritional guidance (NG) induced improvements in metabolic syndrome (MetS) risk factors, vascular function parameters and ideal cardiovascular health (CVH) in sedentary and overweight adults, and to compare the training adaptations between intervention groups.

Adaptations of skeletal muscle to endurance exercise and their metabolic consequences
J. O. Holloszy,Edward F. Coyle +1 more
TL;DR: The major metabolic consequences of the adaptations of muscle to endurance exercise are a slower utilization of muscle glycogen and blood glucose, a greater reliance on fat oxidation, and less lactate production during exercise of a given intensity.

Exercise induces transient transcriptional activation of the PGC-1α gene in human skeletal muscle
TL;DR: It is demonstrated that exercise induces a dramatic transient increase in PGC‐1α transcription and mRNA content in human skeletal muscle, consistent with its role as a transcriptional coactivator, and suggest that PGC•1α may coordinate the activation of metabolic genes in human muscle in response to exercise.
