“…These results are in line with a previous study, in which similar training loads were shown to induce central fatigue . It has been also demonstrated that whole body exercises such as repeated high intensity cycling or running sprints produce similar amounts of central fatigue …”

“…The most interesting question is why only the HIRC session induced peripheral fatigue in knee extensor muscles when the total time under tension and local resting periods for each muscle group were identical between HIRC and TST. A difference between HIRC and TST was the level of accumulated lactate: HIRC induced lactate concentrations (11.6 ± 2.2 mMol·l −1 ) comparable to those reported after a Wingate test and after repeated maximal intensity‐sprints on a cycle ergometer . In contrast, TST resulted in much lower lactate concentrations (4.7 ± 1.6 mMol·l −1 ).…”

“…Recent studies have shown that high intensity whole body exercise exacerbates both central and peripheral fatigue. 4,5 Heavy resistance training loads (2-6 repetition maximum, RM) have been shown to induce central fatigue, 6,7 while lower loads (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) are assumed to elicit hypertrophy by means of a peripheral response in the muscle. 8 However, no study has been conducted to investigate central and peripheral fatigue induced by a modality of resistance training known as circuit training.…”

Introduction: The aim of this study was to investigate the effects of high intensity resistance circuit (HIRC) and traditional strength training (TST) on neuromuscular fatigue and metabolic responses. Methods: Twelve trained young subjects performed HIRC and TST in a counterbalanced order with 1 week rest in-between. The amount of workload and the interset time for each local muscle group were matched (180 s), however, the time between successive exercises differed. The twitch interpolation technique was used to test neuromuscular function of the knee extensor muscles. Blood lactate concentration was used to evaluate metabolic responses. Results: Maximum voluntary contraction and resting potentiated twitch amplitude (Q tw ) were significantly reduced after HIRC, but there were not changes after TST, while reductions in voluntary activation were similar. Lactate concentration increased significantly more after HIRC. Conclusions: The higher lactate concentration after HIRC probably impaired excitation-contraction coupling, indicating larger peripheral fatigue than after TST. 56: 152-159, 2017 Resistance training is an excellent method to enhance muscular hypertrophy, strength, power, and local muscular endurance. Although the physiological mechanisms underlying these changes remain unclear, disturbances in homeostasis associated with acute muscular fatigue could be the foundation of the strength adaptations. Muscle Nerve1 Therefore, muscular fatigue induced by a bout of resistance exercise could account for long-term muscular adaptations.

“…For instance, a 24 s recovery has been used in protocols of 5 × 6 s (number of trials × duration of each trial) [16]; a 20 and 90 s recovery has been used in 12 × 4 s [18]; a 25, 50 and 100 s recovery in 10 × 5 s [24]; a 30 s recovery in 4 × 10 s [21], 5 × 6 s [9] and 6×6 s protocols [8]; 30 s, 1 and 5 min recovery in 10 × 10 s [27]; and a 40 s recovery in a 10×10 s protocol [17]. Moreover, longer recovery times have ranged from 1.5, 3 and 6 min in 2 × 30 s [3]; 3 min in 10 × 10 s [25]; 4 min in 3 × 30 s [32] and in 6 × 30 s protocols [20]; 5 min in 5 × 60 s [7]; and 20 min in a 3 × 30 s protocol [1].…”

“…Observing the above-mentioned RSE protocols, a trend that should be highlighted is the use of a relatively large recovery time (>1 min) mostly when the trial lasts for at least 30 s. During these exercises, fatigue is recorded as changes in the power output, the blood lactate concentration and the knee extension maximum voluntary contraction force [18,24,25].…”

SummaryStudy aim: The aim of the present study was to examine the effect of two different recovery durations (2 min versus 5 min) on the physiological responses (power output, stretch-shortening cycle and lactate concentration) to a 5×6 s repeated cycling sprint exercise protocol in pre-pubescent soccer players. Materials and methods: Twelve male soccer players (age 12.23 ± 0.55 yrs, body mass 43.6 ± 5.5 kg and height 156.1 ± 5.8 cm) performed 5 × 6 s sprints on a cycle ergometer (Ergomedic 874E, Monark, Sweden) against 0.075 times their body mass resistance on two occasions within a week. In one session there was a 2 min recovery and in the other there was a 5 min recovery in a counterbalanced order. A squat jump (SJ) and a countermovement jump (CMJ) were tested before and after each trial, and the eccentric utilisation ratio (EUR) was calculated as CMJ/SJ. Results: No significant trial × recovery interaction was observed in the participants' peak power (p = 0.891, η 2 = 0.118), mean power (p = 0.910, η 2 = 0.106), SJ (p = 0.144, η 2 = 0.630), CMJ (p = 0.616, η 2 = 0.347) and EUR (p = 0.712, η 2 = 0.295). However, a main effect of the trial on the CMJ of a large magnitude (p = 0.006, η 2 = 0.862) was found, in which a higher score was recorded in the third trial than in the first trial (23.3 versus 21.8 cm). No differences were found in the lactate concentrations examined 5 min after the end of the protocol between the two recovery conditions (6.7 ± 1.8 vs. 6.0 ± 1.6 mmol · L -1 , in the 2 and 5 min recovery, respectively, Cohen's d = 0.4). Conclusions:The duration of the passive recovery time (2 min vs. 5 min) in trials of repeated sprints did not induce important changes either to the indices of the jumping performance or to the power output in pre-pubescent participants.

Neuromuscular fatigue of the knee extensors during repeated maximal intensity intermittent‐sprints on a cycle ergometer

Abstract: The maximal intermittent sprints induced neuromuscular fatigue. Neuromuscular fatigue in the first 5 sprints was mainly peripheral, whereas in the last 5 sprints it was both peripheral and central.
