This 6‐week pilot study aimed to investigate the feasibility, perceived efficacy, and participation perspectives of a university campus stair climbing‐based exercise snack (ES) intervention and to compare it to moderate‐intensity continuous training (MICT). Healthy, young, inactive adults (age: 21.6 ± 2.3 years, BMI: 22.5 ± 3.6 kg/m2) were randomly assigned to three groups (ES, MICT, and Control [CON])

Training one limb with a high‐load has been shown to augment strength changes in the opposite limb training with a low‐load (via cross‐education of strength), indicating that within‐subject models can be problematic when investigating strength changes. This study examined if the cross‐education of strength from unilateral high‐load training could augment the strength changes in the opposite arm undergoing

To investigate the effect of moderate or heavy slow resistance training on structural and mechanical properties of patellar and Achilles tendons in older men, in vivo. Healthy older men (n = 27) undertook a 12‐week resistance training program (3 times/week) of triceps surae and quadriceps muscle‐tendon complexes. Participants were randomly assigned to either a moderate load of 55% 1RM (O55, n = 13

The decline in fitness levels among children and adolescents underscores the urgent need for effective exercise interventions. Aerobic endurance training (ET) and resistance training (RT) are vital for physical development in this demographic. This study employs multivariate and network meta‐analysis (NMA) to assess the impact of concurrent training (CT), which integrates both ET and RT, on youth physical

Previous findings of sex‐differences in type, location, consequences, and risk factors of running‐related injuries (RRIs) are contradictory. We aim to clarify these potential sex‐differences. This cohort study analyzed prospective RRIs among recreational runners participating in running events (5–42 km) by combining data of two RCTs, including all intervention arms. Participants received a baseline

The ability to accelerate and attain high velocities is essential for both individual and team sport athletes. The purpose of this explorative study was to retrospectively analyze the ground reaction force using Statistical Parametric Mapping (SPM) vector field analysis, as traditional scalar analyses often fail to acknowledge the interdependence of force vector components. The ground reaction force

The application of force is a key aspect of performance during athletic activities. In jumping, the timing and magnitude of force application are important performance factors. The relative timing of forces has only been investigated in the countermovement jump. This study aimed to explore if the synchronization of peak concentric force with the instance of zero velocity during a drop jump impacted

Magnetic resonance imaging (MRI) is the gold standard for measuring muscle size. However, postural conditions for thigh musculature have not been standardized across studies, with some employing supine or prone positions and the thigh either placed on the examination table or suspended to avoid contact. In either case, the thigh is compressed or sagged by gravity, potentially affecting muscle size

The U.S. National Health and Nutrition Examination Survey (NHANES) physical activity monitor datasets for 2011–12 and 2013–14 were released in late 2020.
