“…1c). CMJ height has turned out to be a useful and simple tool for monitoring and quantifying neuromuscular fatigue induced by the sprint training session [15,16]. In our study, CMJ height (expressed as %CMJ max ) showed a strong relationship with blood lactate concentration (r = − 0.83) (▶ Fig.…”

“…This relationship suggests that the athletes with the lowest %CMJ max values, which means the highest loss of CMJ height, tended to be those with the highest blood lactate concentration and, therefore, with the highest anaerobic glycolysis activation. Previous studies have also shown strong correlations between the CMJ height loss and the metabolic responses such as lactate and ammonia in sprinters (r = 0.95 and r = 0.96, respectively) [15] and in 400-m runners (R 2 = 0.68 and R 2 = 0.51, respectively) [20]. Gorostiaga et al [20] suggested that for blood lactate levels not exceeding 8-12 mmol • L − 1 , the jumping height did not change significantly from maximum values; however, when blood lactate concentrations came to exceed approximately 8-12 mmol • L − 1 , the jumping height decreased sharply.…”

“…On the other hand, the mechanical response is usually monitored by vertical jump tests [15,16] or kinematic parameters such as: stride length, stride frequency, contact times [17][18][19]. In this line, loss of running velocity and countermovement jump (CMJ) height are considered as good markers of fatigue during sprint training [15,16].…”

“…Previous research has described metabolic and neuromuscular performance characteristics of several typical training sessions in different groups of track & field athletes: sprinters [15,16], 400-m runners [20], and 800-m runners [21]. However, limited scientificbased information is available concerning the metabolic and mechanical responses to different typical training sessions performed by 800-m athletes.…”

The purpose of this study was to describe the mechanical and metabolic responses of a typical high-intensity training session in high-level 800-m athletes. Nine male high-level 800-m athletes (personal best 1:43–1:56 min:ss) performed a typical high-intensity interval training session consisting of 5×200 m with 4 min rest. Countermovement jump and blood lactate were measured at rest and after each running bout. Running times, ground contact times, and stride length were also measured. Running times and lactate (p<0.01) progressively increased from the first to the last running bout. Jump height (p<0.01) and stride length (p<0.05) progressively decreased from the first running bout to the last. A significant negative relationship (p<0.001; r =−0.83) was found between the individual values of jumping height and blood lactate concentration; and a significant positive relationship (p<0.01; r=0.67) was observed between the time in the 200 m and the contact times. In conclusion, the results demonstrated that the typical training session performed by 800-m athletes produced a high level of fatigue as evidenced by significant alterations in the mechanical and metabolic response. The impairments observed in the mechanical and metabolic parameters may indirectly reflect a state of energy deficit of the muscle contractile machinery and a reduction of the force-generating capacity.

“…However, the physiological impact associated with acute fatigue and recovery using different modified SIT protocols has not been described. In this respect, practical and simple evaluation tools such as HR recovery (HRR), HR variability (HRV) (Stanley, Peake, & Buchheit, 2013), and vertical jump performance (Jimenez-Reyes, et al, 2016;Morcillo, et al, 2015) could be useful for identifying differences in acute fatigue between SIT protocols. This information could be important for designing complex training sessions in which strength exercises are performed after endurance efforts (Fyfe, Bartlett, Hanson, Stepto, & Bishop, 2016).…”

The aim of this study was to compare the physiological, mechanical and perceptual responses to two sprint interval training (SIT) sessions with very short vs. long sprints, and to verify if those differences could be reflected in measures of acute fatigue. Eleven physically active men performed, after the maximum oxygen consumption (VO2max) determination, SIT5s (16×5s with 24s of recovery) and SIT20s (4×20s with 120s of recovery) in random order on a cycle ergometer. Physiological, mechanical, and perceptual responses were evaluated during and after the sessions. The countermovement jump (CMJ) height and autonomic control of heart rate (HR) were evaluated before and after the sessions. Diet was also controlled through recall questionnaires. During the training, SIT5s exhibited greater HR, VO2, power output, and total work (TW) (p<.05). In contrast, respiratory exchange ratio (RER), rate of fatigue (RF), and blood lactate (BLa) % accumulation were greater in SIT20s (p<.05). The OMNI-cycle Scale Rating of Perceived Exertion (OMNIcycle scale) and Feeling Scale (FS) scores were similar during both protocols (p>.05). A faster HR recovery (HRR) and a higher CMJ height were observed after the SIT5s (p<.05). However, HR variability (HRV) was similarly depressed after both protocols (p>.05). Some correlations between the mechanical and physiological responses were revealed only in the SIT5s. SIT5s was demonstrated to be more efficient as exhibited by greater mechanical responses associated with a higher aerobic activity, when compared to the volume-matched SIT protocol of longer sprints. Simple monitoring tools such as HRR and CMJ could help practitioners to detect differences in acute fatigue after different SIT sessions.

Purpose To determine the recovery kinetics of performance and exercise-induced muscle damage following different sprint-training protocols. Methods In a crossover design, ten male and female athletes (20.6 ± 2.4 years) performed 2 × (3 × 20 m: 2 min rest) and 1× (3 × 30 m: 3 min rest) of: (a) unresisted sprints (UST), (b) resisted sprints with 10% of body mass (BM) load (RST10), (c) resisted sprints with 20% BM load (RST20), against a control trial (no-training). Results Blood lactate (mmol/L) increased post-training versus pre-training in all sprint-training trials (6.7 ± 2.4 vs 1.2 ± 0.2, 5.6 ± 2.4 vs 1.3 ± 0.3, 7.3 ± 2.7 vs 1.2 ± 0.3, in UST, RST10, RST20, respectively), as did creatine kinase (U/L) 24 h, 48 h and 72 h post-training (UST: 251 ± 173, 238 ± 154, 209 ± 115 vs 155 ± 9, RST10: 252 ± 134, 240 ± 83, 218 ± 103 vs 164 ± 106; RST20: 237 ± 133, 323 ± 303, 262 ± 184 vs 179 ± 106, respectively). DOMS of knee-extensors (KE) and knee-flexors (KF) increased post-training up to 72 h in all sprint-training trials versus pre-training (ranging from 1.6 ± 1.3 to 3.8 ± 2.8 vs 1.0 ± 0, respectively). Eccentric torque (N m) of the KE of the non-dominant limb, decreased 24 h post-training versus pre-training in all sprint-training trials (UST: 249 ± 49 vs 266 ± 54; RST10: 229 ± 52 vs 273 ± 72; RST20: 253 ± 6 vs 262 ± 56), as did that of the KF of the dominant limb (UST: 135 ± 29 vs 144 ± 26; RST10: 130 ± 29 vs 140 ± 25; RST20: 139 ± 33 vs 142 ± 26). 10-m sprint-time (s) increased 48 h post-training versus pre-training (1.81 ± 0.15 vs 1.77 ± 0.11), and 30-m sprint-time increased 24 h, 48 h, 72 h post-training versus pre-training (4.35 ± 0.36, 4.40 ± 0.44, 4.33 ± 0.41 vs 4.21 ± 0.34, respectively), only in RST20. Conclusions Unresisted and resisted sprint-training induces prolonged reduction of muscle strength (24 h), and sprinting performance (72 h), associated with prolonged increase of DOMS and CK (72 h).
