Sports Performance and Training

This paper develops a force-velocity elasticity framework to quantify how maximal force and velocity affect sprint time across distances, identifying key relationships and a valley distance for minimal sprint time response.

A 32-week plyometric training program improved jumping performance and reduced force-velocity imbalance in collegiate volleyball players compared to a low-intensity control group.

This paper introduces Phys-PC, a physiology-aware model for football pitch control that detects structural patterns and predicts match outcomes based on physiological constraints.

This study compares skeletal age, growth hormones, and physical fitness across age groups of elite youth football players, finding increases in skeletal age, fitness, and IGF-1 with age, but no change in GH.

This study examines how preparatory force constraint affects explosive force generation during base stealing in baseball, finding that force constraint in a specific timing window significantly influences peak rate of force development.

This study compares acute and chronic adaptations in vastus lateralis muscle from lengthened partial versus full range of motion resistance training in trained males, finding similar outcomes but potential hamstring differences.

This study uses a structural equation model to show that muscle stiffness and relaxation time predict explosive performance in weightlifters, with weak links to other mechanical properties.

This study examines how biological maturation and relative age effect influence talent identification in U16 elite soccer players, finding significant impacts of maturation on physical and performance metrics but not on selection criteria.

This study examines how rider ability and position affect tandem cycling performance, finding that equal and unequal-capacity pairs show similar performance, with stokers producing lower power and perceived exertion.

This study compares velocity-based training (VBT) and percentage-based training (PBT) on body composition, strength, and performance metrics in men, finding VBT yields better outcomes with lower load.

This paper builds a model to simulate how acute aerobic exercise affects rate of force development in weightlifters and develops a prediction equation for interference effects.

This paper shows that the gap between elite female and male runners has continued to shrink since 2001 across all distances, contrary to the belief that it stabilized in the late 20th century.

This study investigates how resistance training volume affects skeletal muscle adaptations and inter-individual response variation using a within-participant design, finding detectable benefits for hypertrophy but not strength, and limited evidence of true inter-individual differences.

This study examines changes in countermovement jump performance and subjective recovery in women's volleyball players after a match, finding no significant decline in jump variables but no recovery in subjective well-being measures.

This study examines contrast water therapy's effects on recovery in swimmers, finding reduced lactate and fatigue without affecting performance or blood pressure.

This study examines how morning resistance exercise affects afternoon physical and cognitive performance in male rugby players, finding improvements in physical performance but not cognitive tasks.

Athlytics provides an R framework for longitudinal exercise physiology analysis of Strava API data, enabling standardized computation of physiological indicators and visualization.

This study compares low-load and high-load resistance training in trained individuals, finding comparable increases in strength and hypertrophy with LL-RET.

This study compares time-to-exhaustion during level and uphill running at critical intensity using wearable devices measuring power and muscle oxygenation, finding shorter endurance and faster oxygen decline on level terrain.

This study compares external and internal load profiles between male and female participants in a walking football tournament, finding higher external load in males but similar internal load.

This study examines the relationship between muscle strength and size before and after unilateral resistance training in males and females, finding sex differences in correlation strength and causal relationships.

This study evaluates functional training's impact on athlete muscle strength compared to traditional resistance training, finding moderate to large effects on maximum strength, power, and muscle endurance.

This study examines the relationship between rate of force development (RFD) and neuromuscular variables in basketball athletes, finding that RFD correlates more with motor unit firing frequency than with maximum strength or recruitment.
