Performance for short intermittent runs: active recovery vs. passive recovery

Abstract

The purpose of this study was to compare the effects of active vs. passive recovery on the time to exhaustion for intermittent runs (15 s) at supramaximal velocity (120% of maximal aerobic speed). Twelve male subjects performed a graded test, an intermittent run to exhaustion with active recovery (50% of maximal aerobic speed) and an intermittent run to exhaustion with passive recovery. Results showed that intermittent runs to exhaustion with passive recovery [745 (171) s] allowed subjects to run for a significantly longer (p<0.001) time than intermittent runs to exhaustion with active recovery [445 (79) s]. These results could be explained by a significantly higher (p<0.001) energy requirement for intermittent runs with active recovery [59.9 (9.6) ml.kg(-1).min(-1)] than for intermittent runs with passive recovery [48.9 (6.9) ml.kg(-1).min(-1)]. It could be also hypothesized that the energy required to run during short active recovery would result in less oxygen being available to reload myoglobin and haemoglobin, to remove lactate concentrations and to resynthesize the phosphocreatine. Consequently, for intermittent runs with short recovery periods, passive recovery will induce a longer time to exhaustion than active recovery.

Heart Rate Responses During Small-Sided Games and Short Intermittent Running Training in Elite Soccer Players: A Comparative Study

“…Dupont and Berthoin (17) have shown that the AR could be less efficient than the PR to optimize _ VO 2 max, because of the fact that AR enhances blood lactate removal in comparison with PR (13,24,33). Moreover, PR could allow greater reoxygenation of myoglobin and hemoglobin than AR (18,19). The results of this latter study showed that there were no significant differences between AR and PR concerning blood lactate concentration (12.6 6 1 versus 13.1 6 2.7 mmolÁL 21 ), peak HR (183.3 6 13.9 versus 182.5 6 15 bÁmin 21 ) and average HR (66.6 6 11.9; 165.6 6 14.6 bÁmin 21 , respectively).…”

The Comparison of the Effects of Two Types of High IntensityInterval Training (HIIT) on Body Massand Physiological Indexes in Inactive FemaleStudents

“…Muscle lipolysis triglyceride (intermuscular fat uptake) is only stimulated in higher intensity physical activities [2,25]. In comparison with moderate to low intensity physical activity, HIIT induces metabolic adaptations in skeletal muscle which is beneficial to fat oxidation (fat burning) and the energy consumption level is beneficial to negative energy and fat balance in high intensity physical activity more than moderate to low intensity physical activities [15].…”

“…Today's world has witnessed huge revolutions in science and technology by which humans have dominated their environment more than ever before. The reason for all these improvements can be attributed to the application of numerous researches in all scientific fields [2]. No doubt activity and liveliness have always been inseparable parts of human life and have manifested themselves in special forms during different ages.…”

“…Baiati et al [2] showed that 6 weeks of HIIT and traditional endurance training resulted in similar metabolic adaptations in adults. Ferguson et al [19] showed that body fat percentage significantly reduced after 6 weeks of HIIT in inactive young men while weight, BMI and waist to hip ratio did not show any significant changes.…”

Effects of a high-intensity interval training protocol based on functional exercises on performance and body composition in handball female players

“…As opposed to steady-pace and continuous training, interval training builds up more high-intensity stimuli, closer to collective sports requirements, such as in those in handball (Dupont et al, 2003;Buchheit et al, 2007;Buchheit & Laursen, 2013). HIIT therefore becomes a good time-efficient strategy to spur in training adaptation similar to competition (Burgomaster et al, 2005;Martins et al, 2016).…”
