“…The peak power (Fig. 3, panels A and B) was obtained around 6 second at the AO30, and the curve fit behaviour in tethered running was similar to that observed in another 30 s all-out kind of exercise, such as power responses in cycle ergometer 25 and force curve in swimming 57 and kayak effort 58 . In contrast, the peak of running velocity in our experiment was obtained within a lower time than that recently observed by Morrison et al 17 who submitted amateur athletes to four series of AO4s sprints in a non-motorized treadmill (Woodway, Waukesha, Wisconsin).…”

High-intensity exercises including tethered efforts are commonly used in training programs for athletes, active and even sedentary individuals. Despite this, the knowledge about the external and internal load during and after this effort is scarce. Our study aimed to characterize the kinetics of mechanical and physiological responses in all-out 30 seconds (AO30) tethered running and up to 18 minutes of passive recovery. Additionally, in an innovative way, we investigated the muscle oxygenation in more or less active muscles (vastus lateralis and biceps brachii, respectively) during and after high-intensity tethered running by near-infrared spectroscopy-NIRS. Twelve physically active young men were submitted to AO30 on a non-motorized treadmill to determine the running force, velocity and power. We used wearable technologies to monitor the muscle oxygenation and heart rate responses during rest, exercise and passive recovery. Blood lactate concentration and arterial oxygen saturation were also measured. In a synchronized analysis by high capture frequency of mechanical and physiological signals, we advance the understanding of AO30 tethered running. Muscle oxygenation responses showed rapid adjustments (both, during and after AO30) in a tissue-dependence manner, with very low tissue saturation index observed in biceps brachii during exercise when compared to vastus lateralis. Significant correlations between peak and mean blood lactate with biceps brachii oxygenation indicate an important participation of less active muscle during and after high-intensity AO30 tethered running. Physical exercise performed at different intensities promotes distinct physiological responses during both activity and recovery process 1,2. High-intensity and short-volume efforts are widely used in the sports context and have also been extensively adopted in non-athlete training programs, such as high-intensity interval training (HIIT) and sprint interval training 3,4. In the same way, high-intensity tethered exercises (including resisted sled sprinting) performed maximally have been applied to improve physical and athletic performances 5,6. Despite that, there is a lack of knowledge about the mechanical and physiological kinetics during all-out tethered exercise and recovery. This gap can compromise the training load interpretation when this type of effort is adopted. Training load is described as external and internal, depending on which measurements of the athlete/participant are assessed 7. External load is defined as the amount and quality of work performed (e.g. distance covered, velocity and exercise power). On the other hand, the internal load indicates the physiological and psychophysiological responses of the organism to the effort imposed from the external load. However, internal-load indicators, especially during exercise, and the integration of external and internal loads need to be improved 7. Most exercise and recovery studies investigate systemic responses to the observed internal load, such as heart rate and blood lactat...

“…Since the competitive level of futsal athletes may be distinguished by repeated spring ability [9], we believe that further investigations within a less homogeneous group may see a significant relationship between these parameters. Our study is also the first to evaluate futsal athletes under tethered conditions, which have been extensively adopted in several sports [22,23,49]. More importantly, we show that, regardless of sex, the AO30 derived parameters present a significant relationship with agility performance.…”

This study aimed to investigate the relationship between mechanical parameters from the Running-based Anaerobic Sprint Test (RAST2×17.5), agility performance from the Illinois Agility Test (IAT) and all-out 30-second tethered running (AO30) in college futsal athletes. It also investigates whether these protocols are capable of identifying differences between sexes. Twenty subjects were evaluated. The IAT was applied on a specific course and performance was considered as the total time (T.T). The RAST2×17.5 consisted of six maximum efforts in a shuttle exercise of 2x17.5 m per bout. The AO30 was conducted under maximal effort on a non-motorized treadmill. Maximum, mean and minimum power were determined for RAST2×17.5 and AO30. Mean power from RAST2×17.5 was inversely and significantly correlated to T.T regardless of sex (male: r=–0.76; p=0.010; female: r=–0.89; p=0.010). A similar association was noticed for maximum power for females (r=–0.94; p=0.001). The AO30 maximum and mean power were significantly correlated with T.T (male: r=–0.67; p=0.031 and r=–0.66; p=0.035, respectively; female: r=–0.64; p=0.046 and r=0.66; p=0.035, respectively). Maximum power from RAST2×17.5 and AO30 were significantly correlated (male: r=0.68; p=0.030; female: r=0.72; p=0.019). Our results reinforce the adoption of field-based tests like RAST2×17.5 and IAT for futsal, since significant relationships among these parameters and AO30 results were obtained. Moreover, these protocols differentiated male and female athletes by mechanical and agility parameters, proving their application under specific field evaluation.

“…Despite Zamparo, Tomadini, Didone, Grazzina, Rejc, Capelli 1 demonstrating that anaerobic metabolism is predominant during canoe slalom races, the high ACE insertion in the Brazilian athletes evaluated in our study may indicate that the aerobic component is also important for performance improvement in this sport, which was confirmed by the better performance of athletes genotyped as II or ID (97.6±6.6 s; 99.5±9.7 s, respectively) when compared with athletes genotyped as DD (130.0±5.1 s). Moreover, athletes who only have the arginine residue replacement (R) in the premature stop codon (X) encoding the α-actinin-3 (ACTN3) protein (which is related to powerful muscle contraction due to its expression in glycolytic type IIX fibers) 13 also demonstrated better performance, confirming the anaerobic relevance during canoe slalom races proposed by other studies 1,3 .…”

“…While limited information exists about the relationship between vitamin A and exercise 31 , studies described the relevance of adequate vitamin B6 32 , magnesium 33 , thiamine 34 , riboflavin 35 , calcium and phosphorus 36 intake on biological processes related to athletic performance. Considering the high blood lactate levels (8.29±2.43 mM) demonstrated by Messias et al 3 after canoe slalom simulated trials and the importance of vitamins of B6 complex, thiamine, riboflavin in gluconeogenesis process involving the conversion of lactic acid to glucose in the liver 32,34,35 , inadequate intake of this vitamin may influence energetic replenishment after a race. In agreement with this, significant and negative relationships between slalom kayakers' performance and the aforementioned vitamins/minerals were revealed.…”

“…In the last years, studies involving several approaches on the Olympic sport canoe slalom emerged. These investigations provided fundamental advances related to the metabolic demand during simulated race 1 , energy production via aerobic and anaerobic sources throughout physiological evaluation 2,3,4,5 and physical development of slalom kayakers after training 6 . Apart from the metabolic/physiological relevance, other factors such as sleep traits, nutrition, genetic profile and psychological can significantly affect athletes' performance; however, literature involving these factors on canoe slalom is scarce 7 .…”

The aims of this study were to investigate and characterize the anthropometric, nutritional, genetic, psychological and sleep variables of slalom kayakers, and to verify the correlation of these variables with the slalom kayakers' performance. Methods: Ten elite Brazilian team slalom kayakers participated of this study. Nutritional analysis was made by the Food Record (three days), 24 Hour Dietary Recall and Food Frequency Questionnaire. The ACE I/D, AGTMet235Thr, ACTN3R577X and BDKRB2+9/-9 were genotyped for genetic profile. The Profile of Mood States (POMS) and Sports Competition Anxiety Test (SCAT) were applied to investigate the psychological variables. The Pittsburgh Sleep Quality Index (PSQI), Epworth Sleep Scale (ESS) and Morningness-eveningness questionnaire (MEQ) were used for sleep traits analysis. Performance trials were performed on a white-water course with 24 gates, and finish time was considered as the variable related to performance. Results: Significant correlations were obtained between Performance Time Trial and %Fat (r=0.77), Energy (r=-0.75), Protein (r=-0.76), Carbohydrate (r=-0.72), Vitamin B6 (r=-0.87), Vitamin A (r=-0.82), Thiamine (r=-0.77), Riboflavin (r=-0.71), Magnesium (r=-0.86) and Phosphorus (r=-0.74) intake, besides the Fatigue mood domain (r=0.73) and the SCAT score (r=0.67). Athletes genotyped with the I, T, R and +9 alelle also presented better performances. Conclusions: In summary, the novel results provided by this study reinforce the necessity of considering several aspects during athlete development in order to achieve better performance in competitions.
