“…After a standard warm-up, all subjects performed a 30 s “all-out” supramaximal test on a mechanically braked cycle ergometer (884E Sprint Bike, Monark, Vansbro, Sweden). The test was initiated from a dead stop with the resistance equal to 75 g·kg body mass −1 (corresponding to 7.5% of an individual’s body mass) preset on the ergometer’s friction belt [ 31 , 32 ]. The obtained results were analyzed for maximal anaerobic power (MAnP) and work output.…”

Vitamin D3 supplementation can affect strength and power; however, the effect on both aerobic and anaerobic performance remains unclear. Here, we investigate the effects of eight weeks of a high dose of vitamin D3 supplementation and its impact on circulating 25-hydroxyvitamin D (25-OH-D3) concentrations and selected indicators of physical capacity. Subjects (n = 28, age 21.1 ± 1.6) were divided into two groups: supplemented (SUP), which was given 6000 IU of vitamin D3 daily for eight weeks; and placebo group (PLA). Serum 25-OH-D3 concentrations were determined in pre- and post-intervention. Aerobic ( V . O2max test) and anaerobic (Wingate Anaerobic Test) capacity were determined before and after the supplementation. The mean baseline concentration of 25-OH-D3 was recognized as deficient (20 ng/mL) and significantly increased over time in the supplemented group (p < 0.01, η2 = 0.86), whilst it remained unchanged in the placebo group. Moreover, the supplementation caused a significant improvement in maximal aerobic (p < 0.05, η2 = 0.27) and anaerobic power (p < 0.01, η2 = 0.51) whereas no changes were observed in PLA group. The V . O2max differences were also significant in the supplemented group (p < 0.05). In summary, the changes in aerobic and anaerobic capacity observed in this study were associated with a serum concentration of 25-OH-D3. Our data imply that vitamin D3 supplementation with a dose of 6000 IU daily for eight weeks is sufficient to improve physical capacity and vitamin D3 status.

“…The effect size (η 2 ) has also been calculated. The value of η 2 has been interpreted as follows: 0.1 a small effect, 0.3 a medium effect, and 0.5 a large effect, as previously described [ 32 ]. Changes (delta) in both groups were compared using an independent samples t -test or a U-Mann–Whitney test, according to the data distribution.…”

“…After a 5-min warm-up, all subjects performed a 30-s "allout" WAnT on a mechanically braked cycle ergometer (884E Sprint Bike; Monark, Vansbro, Sweden). The test was initiated from a dead stop with the resistance equal to 75 g • kg body mass − 1 (corresponding to 7.5 % of an individual's body mass) preset on the ergometer's friction belt [14]. Then all subjects underwent familiarization of both tests.…”

Changes in Urinary Titin Fragment in Response to Different Types of Dynamic Eccentric Exercises

The urinary level of the titin fragment has been considered a non-invasive and sensitive biomarker for muscle damage in clinical cases. However, there is little evidence regarding changes in the urinary titin fragment in response to exercise-induced muscle damage. In this study, we aimed to investigate whether the urinary titin fragment reflects the magnitude of muscle damage induced by two lower-limb eccentric exercises. In this study, healthy young male subjects performed drop jump (n=9) and eccentric ergometer exercise (n=9). Blood and urine samples were collected at various time points before and after the exercises. Although perceived muscle soreness assessed by sit-to-stand tasks was increased at 24 h and 48 h after both drop jump and the eccentric ergometer exercise groups, the pressure pain threshold was not changed. Changes of the urinary titin fragment, plasma myomesin 3 fragments, creatine kinase (CK), and myoglobin (Mb) after the eccentric exercises were increased but not statistically significant. Meanwhile, we found that the changes in the urinary titin fragment levels in response to both drop jump and the eccentric ergometer exercise were correlated with those of plasma CK and Mb levels. These results provide evidence that the urinary titin fragment level is a non-invasive biomarker reflecting the magnitude of eccentric exercise-induced muscle damage.

“…Previous research based on a two-week training program proved that 10-s bouts (with 4-min recovery) effectively improve cardiorespiratory fitness relative to the "classic SIT" protocol (so called Wingate) composed of 4-6 × 30-s cycle ergometer bouts with 4-min recovery phases [6]. Another research project indicates that reducing the recovery time to one minute leads to an expansion of aerobic and anaerobic efficiency following a 2-week training program similar to the one generated by the 4-min recovery protocol [7]. Furthermore, only the protocol with shorter recovery periods reduced fatigue (power drop) during maximal anaerobic exercise (Wingate test) [7].…”

Background: Knowledge of acute responses to different sprint interval exercise (SIE) helps to implement new training programs. The aim of this study was to compare the acute physiological, metabolic and perceptual responses to two different SIE cycling protocols with different recovery durations. Methods: Twelve healthy, active male participants took part in this study and completed four testing sessions in the laboratory separated by a minimum of 72h. Two SIE protocols were applied in randomized order: SIE6×10”/4’—six “all-out” repeated 10-s bouts, interspersed with 4-min recovery; and SIESERIES—two series of three “all-out” repeated 10-s bouts, separated by 30-s recovery and 18-min recovery between series. Protocols were matched for the total work time (1 min) and recovery (20 min). Results: In SIESERIES, peak oxygen uptake and peak heart rate were significantly higher (p < 0.05), without differences in peak blood lactate concentration and mean rating of perceived exertion compared to SIE6×10”/4’. There were no differences in peak power output, peak oxygen uptake and peak heart rate between both series in SIESERIES. Conclusions: Two series composed of three 10-s “all-out” bouts in SIESERIES protocol evoked higher cardiorespiratory responses, which can provide higher stimulus to improve aerobic fitness in regular training.
