This study was aimed to: (1) investigate the effects of physiological functions of sprint interval training (SIT) on the aerobic capacity of elite badminton players; and (2) explore the potential mechanisms of oxygen uptake, transport and recovery within the process. Thirty-two elite badminton players volunteered to participate and were randomly divided into experimental (Male-SIT and Female-SIT group) and control groups (Male-CON and Female-CON) within each gender. During a total of eight weeks, SIT group performed three times of SIT training per week, including two power bike trainings and one multi-ball training, while the CON group undertook two Fartlek runs and one regular multi-ball training. The distance of YO-YO IR2 test (which evaluates player’s ability to recover between high intensity intermittent exercises) for Male-SIT and Female-SIT groups increased from 1083.0 ± 205.8 m to 1217.5 ± 190.5 m, and from 725 ± 132.9 m to 840 ± 126.5 m (p < 0.05), respectively, which were significantly higher than both CON groups (p < 0.05). For the Male-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VO2max significantly increased from 3088.4 ± 450.9 mL/min to 3665.3 ± 263.5 mL/min (p < 0.05),and from 74 ± 10% to 85 ± 3% (p < 0.05) after the intervention, and the increases were significantly higher than the Male-CON group (p < 0.05); for the Female-SIT group, the ventilatory anaerobic threshold and ventilatory anaerobic threshold in percentage of VO2max were significantly elevated from 1940.1 ± 112.8 mL/min to 2176.9 ± 78.6 mL/min, and from 75 ± 4% to 82 ± 4% (p < 0.05) after the intervention, which also were significantly higher than those of the Female-CON group (p < 0.05). Finally, the lactate clearance rate was raised from 13 ± 3% to 21 ± 4% (p < 0.05) and from 21 ± 5% to 27 ± 4% for both Male-SIT and Female-SIT groups when compared to the pre-test, and this increase was significantly higher than the control groups (p < 0.05). As a training method, SIT could substantially improve maximum aerobic capacity and aerobic recovery ability by improving the oxygen uptake and delivery, thus enhancing their rapid repeated sprinting ability.

AIMS: Musical theatre (MT) combines acting, singing, and dancing within a performance. The purpose of the current study was two-fold: 1) to report on the cardiorespiratory fitness of pre-professional MT dancers, and 2) to examine the cardiorespiratory demand of singing whilst dancing. METHODS: Twenty-one participants (16 females, 5 males; age 20±1.23 yrs; height 169.1±9.24 cm; weight 62.7±10.56) in their final year of pre-professional training volunteered for the study. All participants performed a maximal aerobic capacity test on a treadmill using a portable breath-by-breath gas analyser. Nine participants completed a 4-minute section from Chorus Line twice, singing and dancing and just dancing, in a randomised order whilst wearing the same portable gas analyser. Blood lactate was measured at the end of each trial. RESULTS: Male participants had significantly greater peak oxygen consumption (M vs F, 67.6±2.30 vs 55.6±4.42 mL/kg/min, p<0.001) and anaerobic threshold (% of peak VO2) (54.6±4.04% vs 43.1±3.68%, p<0.001), whilst maximum heart rate and heart rate at anaerobic threshold were similar. The physiological demands of dancing vs singing + dancing were similar, with the exception of the singing + dancing trial having significantly reduced mean breathing frequency and increased lactate (p<0.01). CONCLUSIONS: MT dancers’ aerobic capacity is greater than that observed in other theatre-based dance genres. The observed breathing frequency and lactate differences in the Chorus Line trails could be due to singing reducing breathing frequency, thereby influencing cardiorespiratory recovery mechanics and subsequently blood lactate levels.

The possibility of revealing informative markers for assessing the functional state and special working capacity of highly skilled multihorts by means of correlation analysis is considered. It is established that the values of the relative and explosive strength of most muscle groups have prognostic significance as a criterion for their physical fitness. The priority of extensor musculature for achieving high sports results in athletics decathlon is proved. It was found that the parameters of the anaerobic threshold, determined by the heart rate, are more related to the athletic result than the anaerobic threshold values determined by the amount of oxygen consumed. Five groups of indicators were distinguished, which had a strong relationship with the athletic result in the decathlon. The first group included markers that characterize the aerobic capacity of the body: the relative level of maximum oxygen consumption, anaerobic threshold, pulmonary ventilation, respiratory coefficient and vital capacity of the lungs. The second group consisted of parameters reflecting the rate of recovery of aerobic capacity of the body within 2 minutes after the end of physical activity: heart rate, respiratory, oxygen consumption and pulmonary ventilation. The third group included the values of energy metabolism in the central, right and left temporal regions of the brain, where the higher centers of the motor and sensory systems are located, as well as the centers of the descending pyramidal tract responsible for performing arbitrary movements. The fourth group included indicators characterizing the background mental state, speed and accuracy of the attentional set-shifting, psycho-emotional stability. The fifth group consisted of parameters of the analysis of the heart rate, which reliably correlated with the sum of points in the decathlon.

Recent studies have indicated that certain food products have ergogenic potential similar to that of sports supplements. The present study aimed to investigate the potential ergogenic effect of integral purple grape juice on the performance of recreational runners. Twenty-eight volunteers of both sexes (age, 39.8 ± 8.5 years; peak oxygen consumption, 43.2 ± 8.5 mL/(kg·min)) were randomized into either a group that received grape juice (grape juice group (GJG), n = 15; 10 mL/(kg·min) for 28 days) or a group that received an isocaloric, isoglycemic, and isovolumetric control beverage (control group (CG), n = 13). A time-to-exhaustion exercise test, anaerobic threshold test, and aerobic capacity test were performed, together with assessments of markers of oxidative stress, inflammation, immune response, and muscle injury, performed at baseline and 48 h after the supplementation protocol. The GJG showed a significant increase (15.3%) in running time-to-exhaustion (p = 0.002) without significant improvements in either anaerobic threshold (3.6%; p = 0.511) or aerobic capacity (2.2%; p = 0.605). In addition, GJG exhibited significant increases in total antioxidant capacity (38.7%; p = 0.009), vitamin A (11.8%; p = 0.016), and uric acid (28.2%; p = 0.005), whereas α-1-acid glycoprotein significantly decreased (20.2%; p = 0.006) and high-sensitivity C-reactive protein levels remained unchanged. In contrast, no significant changes occurred in any of these variables in the CG. In conclusion, supplementation with purple grape juice shows an ergogenic effect in recreational runners by promoting increased time-to-exhaustion, accompanied by increased antioxidant activity and a possible reduction in inflammatory markers.

Abstract Background This study was aimed at evaluating the aerobic capacity of patients with antisynthetase syndrome (ASS) and dermatomyositis (DM) and analyzing possible relationships between aerobic capacity and disease status, cardiovascular diseases and their risk factors. Methods The study was a cross-sectional, single-center study that assessed the aerobic capacity of 22 women (13 with DM and 9 with ASS) who were matched by age and body mass index to 17 healthy women (control group). The aerobic capacity (oxygen uptake [VO2 peak], anaerobic threshold, respiratory compensation point and time-to-exhaustion) was evaluated using the cardiopulmonary treadmill test. Disease status was assessed using International Myositis Assessment & Clinical Studies Group (IMACS) set scores. Results The patients had low IMACS parameters that showed low or absent disease activity. The distribution of cardiovascular diseases and their risk factors was similar between the patients and the control group (P >  0.05) at the time of the analysis. The patients with DM and the control group had similar aerobic capacity. However, the patients with ASS exhibited significantly reduced aerobic capacity (relative VO2 peak, anaerobic threshold, respiratory compensation point and time to exhaustion) when compared to the control group. In addition, patients with ASS had a lower anaerobic threshold compared to the DM group. There were no significant relationships between the aerobic capacity and disease status, cardiovascular diseases and their risk factors. Conclusion In contrast to DM patients and healthy individuals, patients with stable ASS have significantly impaired aerobic capacity, which is unlikely to be totally explained by traditional cardiovascular diseases, their risk factors and disease status. Further studies are needed to corroborate our data and to clarify the cause of this reduced aerobic capacity in ASS.
