Neuromechanical adaptations in the gastrocnemius muscle after Achilles tendon rupture during walking.

Although some Achilles tendon rupture (ATR) patients regain function in low-force levels activities, it is not yet well known how neuromuscular and structural alterations after ATR manifest during everyday-locomotion. This study assessed medial gastrocnemius (MG) fascicle shortening during walking 1-year after ATR. Additionally, we explored neuromuscular alterations in lateral gastrocnemius (LG), soleus and flexor hallucis longus (FHL) muscles.

Validity of IMU sensors for assessing features of walking in laboratory and outdoor environments among older adults.

Introduction: IMU sensors (three-dimensional accelerometer, gyroscope and magnetometer) enable assessment of walking in older adults outside the laboratory. We studied whether IMUs are valid for detecting walking parameters (step events, time, length, and cadence) in a laboratory and outdoors on a level surface in older adults.

Methods: This validation study is part of a larger cross-sectional study.

Effects of multicomponent exercise intervention on cardiometabolic risk factors in children and young adults with cerebral palsy: a multiple-baseline trial.

Background: Adults with cerebral palsy (CP) have a high risk of cardiometabolic diseases. It is unknown whether this risk is elevated in young people with CP and whether exercise can reduce this risk. Therefore, we investigated the effects of the EXErcise for Cerebral Palsy (EXECP) intervention on cardiometabolic risk in children and young adults with CP and compared this risk to typically developing children and young adults (TDs).

Serum Metabolome Signature Response to Different Types of Resistance Training.

Pneumatic resistance training (PRT) facilitates a longer time under tension that might lead to greater changes in body composition when compared to traditional resistance training (TRT), possibly enhancing serum metabolite concentrations indicative of healthy metabolic function. To assess the impact of PRT and TRT on muscular strength, body composition, and serum metabolome, 69 men (age: 31.8±7.

Electromyography of Sedentary Behavior: Identifying Potential for Cardiometabolic Risk Reduction.

Introduction: Muscle activation during interruptions to prolonged sedentary time is a hypothesized mechanism underlying observed cardiometabolic benefits. We examined associations of quadriceps and hamstring muscle activity patterns with cardiometabolic risk markers and how these patterns varied between different sitting-interruption countermeasures.

Methods: Electromyographic (EMG) data (shorts) were gathered for 1 to 2 d from healthy adults in a free-living study ( n = 172, age 40.
