Effects of leg immobilization and recovery resistance training on skeletal muscle-molecular markers in previously resistance trained versus untrained adults.

We sought to examine how resistance training (RT) status in young healthy individuals, either well resistance trained (T, n=10) or untrained (UT, n=11), affected molecular markers with leg immobilization followed by recovery RT. All participants underwent two weeks of left leg immobilization via a locking leg brace. Afterwards, all participants underwent eight weeks (3 d/week) of knee extensor focused progressive RT.

Changes in Muscle Quality Following Short-Term Resistance Training in Older Adults: A Comparison of Echo Intensity and Texture Analysis.

Background: Skeletal muscle echo intensity (EI) is associated with functional outcomes in older adults, but resistance training interventions have shown mixed results. Texture analysis has been proposed as a novel approach for assessing muscle quality, as it captures spatial relationships between pixels. It is unclear whether texture analysis is able to track changes following resistance training.

Youth participatory action research (YPAR) to promote educational equity.

The article uses theory and qualitative evidence to show how youth participatory action research (YPAR) can advance educational equity. YPAR engages young people and adult allies in research and action on issues in their schools and communities. Interviews with over two dozen YPAR researchers-students and partner teachers-elaborate the mechanisms through which school-based YPAR can affect equity, including through direct changes to policy and practice as a result of YPAR actions, a school culture that values student experiences, transformative teacher-student relationships, and improved individual outcomes for participants.

Knee Extensor and Flexor Force Control after ACL Injury and Reconstruction: A Systematic Review and Meta-Analysis.

Purpose: Reduced force control after anterior cruciate ligament (ACL) injury and reconstruction may contribute to poor function. Various metrics (linear and nonlinear) have been employed to quantify force control. The aims of this review were to synthesize evidence assessing knee extensor and flexor force control after ACL injury (ACLD) or reconstruction (ACLR) and to investigate the potential effects of injury management (e.

Leg immobilization and subsequent recovery resistance training affect skeletal muscle angiogenesis related markers in young healthy adults regardless of prior resistance training experience.

Unlabelled: We recently reported that resistance trained (T, n=10) and untrained (UT, n=11) young adults experience vastus lateralis (VL) muscle atrophy following two weeks of disuse, and 8 weeks of recovery resistance training (RT) promotes VL hypertrophy in both participant cohorts. However, angiogenesis targets and muscle capillary number were not examined and currently no human studies that have sought to determine if disuse followed by recovery RT affects these outcomes. Thus, we examined whether disuse and/or recovery RT affected these outcomes.
