Lower extremity muscular strength, sedentary behavior, and mortality

Effects of Sedentary Behavior, Physical Activity, Frequency of Protein Consumption, Lower Extremity Strength and Lean Mass on All-Cause Mortality

Background No study has evaluated the potential independent and cumulative effects of physical activity, sedentary behavior, daily frequency of protein consumption, lean mass and muscular strength on mortality risk. Methods Data from the 1999-2002 NHANES were utilized (N = 1,079 adults 50-85 yr), with follow-up through 2011. Leg lean mass was estimated from DXA scans. Knee extensor strength w...

The effects of band exercise using proprioceptive neuromuscular facilitation on muscular strength in lower extremity

The purpose of this study was to examine whether a six-week elastic band exercise program using proprioceptive neuromuscular facilitation (PNF) can increase isotonic strength of abductor muscles in the lower extremity. Twenty-eight healthy students from S university were divided into an experimental group and control group. Each group was participated in pre and post-measurement in isotonic str...

Sedentary behavior and residual-specific mortality

Background: The purpose of this study was to examine the association of accelerometer-assessed sedentary behavior and residual-specific mortality. Methods: Data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) were used (N = 5536), with follow-up through 2011. Sedentary behavior was objectively measured over 7 days via accelerometry. Results: When expressing sedentar...

Muscular Imbalance and Acute Lower Extremity Muscle Injuries in Sport

Lower-extremity Strength, Power and Knee Loading in Young Women

INTRODUCTION The peak knee adduction moment (PKAM) is a gait measure which best represents the mechanical pathology associated with knee osteoarthritis (OA). Recent research has focused on whether the PKAM is modified by muscle function. While knee strengthening exercises reduce pain and improve quality of life, strengthening has little effect on the PKAM in OA [1]. Lower-limb muscle power is m...
