Current Primary Outcome Measures  ICMJE
 (submitted: December 7, 2020)
  • Cardiovascular changes [ Time Frame: Pre and post training (8 weeks) ]
    Maximal oxygen consumption (VO2max) is an indicator of health and fitness. The investigators measured VO2max with a graded exercise using electronically braked cycling ergometer.
  • Blood volume changes [ Time Frame: Pre and post training (8 weeks) ]
    Hematological variables can effect the performance of the people. The investigators measured total blood volume, red blood cell volume, and plasma volume before and after training.

Descriptive Information
Brief Title  ICMJE Effects of Short Duration High-intensity Interval Training on Peak Oxygen Consumption
Official Title  ICMJE Effects of Short Duration High-intensity Interval Training on Peak Oxygen Consumption
Brief Summary High-intensity interval training (HIIT) is an effective tool to improve cardiovascular fitness and maximal anaerobic power. Different methods of HIIT have been studied but the effect of a maximal effort cycling and very short exercise time (i.e., 4-s) with short recovery time (15-30 s) and a high number of repetitions (i.e., 30 bouts) is unknown.
Detailed Description The investigators examined the effects of training at maximal anaerobic power during cycling (PC) on maximal anaerobic power, peak oxygen consumption (VO2peak), and total blood volume in 11 young healthy individuals (age: 21.3±0.5 y) (6 men, 5 women). Methods: Participants trained three times a week for eight weeks performing a PC program consisting of 30 bouts of 4-s at an all-out intensity (i.e., 2 minutes of exercise per session). The cardiovascular stress progressively increased over the weeks by decreasing the recovery time between sprints (30 to 24 to 15-s) and thus session time decreased from 17 to < 10 min.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Cardiovascular Fitness
Intervention  ICMJE Other: 4-s sprint inertial load training
A program employing 30 bouts of 4s inertial load sprint training with progressively reduced recovery time (30 to 15 s) between sprints is effective for improving blood volume, VO2peak and maximal power.
Study Arms  ICMJE Experimental: 4-s sprint inertial load training
Participants trained three times a week for eight weeks following the training program consisting of 30 bouts of 4s all-out cycling on an inertial-load ergometer with progressively decreasing recovery time (30 to 24 to 15s).
Intervention: Other: 4-s sprint inertial load training
