Summary: This study investigates the relationship between the development of slow component of oxygen uptake and muscle fatigue, finding that they are correlated in a time- and intensity-dependent manner. The results suggest that the slow component of oxygen uptake may depend on muscle fatigue, even if the mechanisms of reduced contractile function differ among intensities.

Summary: The level of muscle activation during exercise plays a key role in determining peripheral fatigue, while the amount of work done above critical power does not have a significant impact. These findings contradict previous theories and highlight the importance of muscle activation in severe-intensity exercise-induced fatigue.

Summary: This study found that co-ingesting nitrate-rich beetroot juice and pomegranate powder enhances neuromuscular performance during certain exercises, but does not have a significant effect on others. The combination of beetroot juice and pomegranate powder may compromise aspects of resistance exercise performance when compared to beetroot juice alone.

Summary: This study examined the effects of fatiguing power loading on neuromuscular properties, force production, and metabolic capacities during different phases of the menstrual cycle. The results showed that the effects of the loading protocol varied among the different phases, with ovulation offering a more favorable hormonal milieu for acute neural responses and mid follicular and mid luteal phases being superior for acute muscular responses.

Summary: This study compared voluntary and electrically evoked contractions in terms of peak power and rate of velocity development, and found that voluntary contractions exhibited greater reduction at task termination, while electrically evoked contractions recovered to baseline faster. The study also revealed that the impact of dynamic torque and velocity on peak power varied with different loads.

Summary: The purpose of this study was to examine the accuracy of different W ' balance models in estimating W '(REC) after a 3-minute all-out cycling test (3MT), determine the effects of the 3MT on the power-duration relationship, and assess whether accounting for changes in this relationship improved estimates of W '(REC). The actual W '(REC) was overestimated by some models, but accounting for changes in the power-duration relationship improved their accuracy. These findings have important implications for mathematical models of exercise performance.

Summary: The study aimed to evaluate the effect of head pre-cooling on the 5-km time-trial performance of amateur runners in the heat. Results showed that a 20-minute head cooling intervention improved 5-km running performance in a hot environment, suggesting it could be a practical pre-cooling strategy for both professional and amateur runners.

Summary: This paper proposes a robust time series prediction framework called spARIMA, which reduces noise interference by designing a sequential training scheme in batches based on the degree of noise. spARIMA relies on the differential prediction model in ARIMA and absorbs the advantages of the gradual training scheme in self-paced learning (SPL) to effectively address the instability caused by noise. Furthermore, spARIMA introduces diversity selection to avoid selecting similar samples, using a weighted local complexity-similarity distance expression to represent the diversity of noisy data. Comparative tests with existing ARIMA models on two gradient descent algorithms show that spARIMA not only works well with noisy data, but also performs efficiently with normal data, indicating its generalization ability.

Summary: Kefir, a fermented dairy product, has been shown to improve exercise performance, reduce fatigue, and accelerate recovery in previous studies. The supplementation with SYNKEFIR™ for 28 days significantly increased the exercise time to exhaustion, reduced lactate levels, and did not cause any adverse reactions in the participants.

Summary: The effects of garlic supplementation on 40-km cycling time trial performance, exercise-induced oxidative stress, and inflammatory responses were investigated. The study found that 4-week oral garlic supplementation increased overall antioxidant capacity, attenuated oxidative stress, inflammation, and muscle damage during the cycling exercise, but had no ergogenic effect on cycling performance in healthy males.

The results showed that contractions using muscles related to the performance movement enhanced vertical jump performance, while contractions unrelated to the performance movement may hinder performance.

Summary: The study investigates the effects of prior high-intensity endurance exercise on time trial performance and fatigue responses. The results show that prior high-intensity endurance exercise has positive effects on subsequent time trial performance, despite the development of exacerbated peripheral fatigue. This response may be driven by greater aerobic reliance and exertion tolerance.

Summary: This systematic review with meta-analysis examined the impact of carbohydrate mouth rinse on muscle strength and endurance. The results showed that carbohydrate mouth rinse had no significant effect on maximal strength, but had a positive effect on muscular endurance. The study also found that carbohydrate mouth rinse was more beneficial for muscular endurance when using high workloads, multiple exercises, and a smaller number of rinses.

Summary: This study compared the development of central and peripheral fatigue between Sprint and Olympic distance triathlons. The results showed that peripheral fatigue persisted until after cycling in both distances, while it fully recovered after running in the Olympic triathlon but only partially in the Sprint triathlon. Central fatigue started after cycling and continued until after running in both distances.

Summary: This study aims to find associations between executive function, anxiety, depression, and reactive and anticipatory postural control domains in individuals with moderate-to-severe Parkinson's disease. The results showed that cognitive flexibility, inhibitory control, and anxiety significantly explained different aspects of postural control. These findings have significant implications for future treatments and rehabilitation protocols.

Summary: Perturbation-based balance training (PBT) improves reactive postural responses through sudden upright balance perturbations. A short PBT program was evaluated in individuals with freezing of gait due to Parkinson's disease. Compared to resistance training (RT), PBT led to more stable postural responses in the 30-day retention evaluation, but no transfer to dual-tasking or higher perturbation velocity was observed.

Summary: This study evaluated the effects of medication and freezing of gait (FoG) on the kinematic and kinetic parameters of gait in people with Parkinson's disease. The results showed that FoG mainly affects distal joints, such as the ankle and knee. Parkinson's disease patients exhibited changes in joint range of motion and lower ground reaction force compared to healthy individuals.

Summary: Supplementation with HP beta CD-Ang-(1-7) did not improve physical performance in time trial or repeated sprints, but it promoted the maintenance of plasma glucose and lactate levels after the sprint protocol and at rest, respectively. In addition, HP beta CD-Ang-(1-7) also increased resting plasma nitrite levels and reduced diastolic blood pressure in the time trial protocol.

Summary: This study aimed to create a public dataset of Parkinson's disease (PD) patients' gait biomechanics data. The researchers measured the kinematics of the upper extremity, trunk, lower extremity, and pelvis of 26 PD patients walking overground, both on and off medication. The dataset includes raw and processed kinematic and kinetic data, as well as metadata containing demographic and clinical information. This dataset is expected to provide reference data for researchers worldwide and enhance the understanding of the effects of medication on gait in PD patients.

Summary: The aim of this study was to describe the muscle function, architecture, and composition of long-distance master runners, and verify the association between age and these variables. The analysis demonstrated a weak and negative association between age and some muscle architecture variables and muscle function. However, no association was found between age and muscle composition.
