Unlabelled: At the Olympic level, optimally distributing training intensity is crucial for maximizing performance.
Purpose: The authors evaluated the effect of training-intensity distribution on anaerobic power as a substitute for 1500-m speed-skating performance in the 4 y leading up to an Olympic gold medal.
Methods: During the preparation phase of the speed-skating season, anaerobic power was recorded periodically (n = 15) using the mean power (in watts) with a 30-s Wingate test. For each training session in the 4 wk prior to each Wingate test, the volume (in hours), training type (specific, simulation, nonspecific, and strength training), and the rating of perceived exertion (RPE; CR-10) were recorded.
Results: Compared with the 8 lowest, the 7 highest-scoring tests were preceded by a significantly (P < .01) higher volume of strength training. Furthermore, the RPE distribution of the number of nonspecific training sessions was significantly different (P < .01). Significant (P < .05) correlations highlighted that a larger nonspecific training volume in the lower intensities RPE 2 (r = .735) and 3 (r = .592) was associated positively and the medium intensities RPE 4 (r = -.750) and 5 (r = -.579) negatively with Wingate performance.
Conclusion: For the subject, the best results were attained with a high volume of strength training and the bulk of nonspecific training at RPE 2 and 3, and specifically not at the adjoining RPE 4 and 5. These findings are surprising given the aerobic nature of training at RPE 2 and 3 and the importance of anaerobic capacity in this middle-distance event.

Aim: This study aims to compare the weekly resistance training (RT) frequency between people with diabetes, prediabetes, and without diabetes.
Methods: A total of 536,703 participants from 2017 to 2023 Behavioral Risk Factors Surveillance System were included in the analysis. Unadjusted and adjusted Poisson regression was performed to compare weekly resistance training frequency among participants with different diabetes statuses (without diabetes, prediabetes, and with diabetes).

In Japan, many schools include kendo as part of the school physical education program. Farther afield, kendo also serves as a life-long method to improve and retain physical fitness and mental skills for adults of all ages around the world. Therefore, kendo has the potential to be an inexpensive public health modality if proven safe.

Objectives: This study evaluated the effects of proximal core training on biomechanical risk factors and strength parameters in individuals at high risk of anterior cruciate ligament (ACL) injury (specifically: those exhibiting pathological movement patterns, neuromuscular deficits or biomechanical risk factors) and compared direct versus indirect interventions. We hypothesised that targeted training enhances dynamic knee stabilisation and hip control during high-risk manoeuvres, with direct approaches providing superior biomechanical benefits through neuromuscular control optimisation.
Design: Systematic review and meta-analysis using the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach.

Osteochondral defects caused by trauma, obesity, tumors, and degenerative osteoarthropathies severely impair patients' quality of life. Multilayer tissue engineering scaffolds offer promising strategies for osteochondral repair by enhancing structural biomimicry. In this study, a triple-layer GelMA-alginate-based osteochondral scaffold (TCOS) was fabricated using an enhanced multi-axis, multi-process, multi-material 3D bioprinting system (MAPM-BPS).

Understanding the mechanical behavior of the biceps femoris long head (BFlh) may be insightful due to its high susceptibility to strain injuries, particularly during high-speed running in sports, such as soccer and track and field. While prior research has focused on intrinsic muscle properties, emerging evidence suggests that the biceps femoris short head (BFsh) may influence BFlh tension. Thus, we examined the effects of BFsh load application on the tensile strength and regional shear modulus of the BFlh.
