Combined resistance and endurance training at a moderate-to-high intensity improves physical condition and quality of life in liver transplant patients.

Although currently moderate and high intensity concurrent physical exercise is prescribed in populations with special needs due to its greater effect on physical condition and health-related quality of life (HRQOL), there are no data in the liver transplantation (LT) setting. The aim of this study is to evaluate changes in maximal strength, aerobic capacity, body composition, liver function, and HRQOL in LT patients after a moderate-to-high intensity combined resistance-endurance training. Six months after LT, 54 patients were randomized into 2 groups: intervention group (IG) and control group (CG).

Muscle activation during push-ups performed under stable and unstable conditions.

Background/objective: The purpose of this study was to analyze muscle activation when performing push-ups under different stability conditions.

Methods: Physically fit young male university students ( = 30) performed five push-ups under stable conditions (on the floor) and using four unstable devices (wobble board, stability disc, fitness dome, and the TRX Suspension Trainer). The push-up speed was controlled using a metronome, and the testing order was randomized.

Is physical exercise harmful to liver transplantation recipients? Review of literature.

Liver transplantation is a treatment that significantly improves the patients' quality of life. However, we should be more ambitious and seek an improvement in their fitness through training protocols allowing them to fully return to daily activities. English and Spanish-language articles on PubMed and the Cochrane Library were searched untill 2014.

Core muscle activity in a series of balance exercises with different stability conditions.

Literature that provides progression models based on core muscle activity and postural manipulations is scarce. The purpose of this study was to investigate the core muscle activity in a series of balance exercises with different stability levels and additional elastic resistance. A descriptive study of electromyography (EMG) was performed with forty-four healthy subjects that completed 12 exercises in a random order.

Shoulder muscle activation during stable and suspended push-ups at different heights in healthy subjects.

Objectives: To analyze shoulder muscle activation when performing push-ups under different stability conditions and heights.

Study Design: Comparative study by repeated measures.

Setting: Valencia University laboratory.

Test-retest reliability of the Star Excursion Balance Test in primary school children.

Background: Dynamic balance has been considered a fundamental skill at all ages and is required for normal daily tasks, such as walking, running, or other sports activities. The Star Excursion Balance Test (SEBT) has been widely used in recent years to identify dynamic balance deficits and improvements and to predict the risk of lower extremity injury. However, no study has demonstrated the reliability of the SEBT in children while they are performing the test in a physical education session.

Muscle activity levels in upper-body push exercises with different loads and stability conditions.

Background: Exercises that aim to stimulate muscular hypertrophy and increase neural drive to the muscle fibers should be used during rehabilitation. Thus, it is of interest to identify optimal exercises that efficiently achieve high muscle activation levels.

Objective: The purpose of this study was to compare the muscle activation levels during push-up variations (ie, suspended push-ups with/without visual input on different suspension systems, and push-ups on the floor with/without additional elastic resistance) with the bench press exercise and the standing cable press exercise both performed at 50%, 70%, and 85% of the 1-repetition maximum.

Muscle Activation during Push-Ups with Different Suspension Training Systems.

The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29) performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized.

Bench press and push-up at comparable levels of muscle activity results in similar strength gains.

Electromyography (EMG) exercise evaluation is commonly used to measure the intensity of muscle contraction. Although researchers assume that biomechanically comparable resistance exercises with similar high EMG levels will produce similar strength gains over the long term, no studies have actually corroborated this hypothesis. This study evaluated EMG levels during 6 repetition maximum (6RM) bench press and push-up, and subsequently performed a 5-week training period where subjects were randomly divided into 3 groups (i.

Muscle activation in young men during a lower limb aquatic resistance exercise with different devices.

Little research has been reported on the effects of using different devices with resistance exercises in a water environment. This study compared muscular activation of lower extremity and core muscles during leg adduction performed at maximum velocity with drag and floating devices of different sizes. A total of 24 young men (mean age 23.

Exercise and ankle sprain injuries: a comprehensive review.

Ankle sprains are common in team sports and sports played on courts, and often result in structural and functional alterations that lead to a greater reinjury risk. Specific exercises are often used to promote neuromuscular improvements in the prevention and rehabilitation of ankle injuries. This literature review summarizes the neuromuscular characteristics of common ankle sprains and the effectiveness of exercise as an intervention for improving neuromuscular function and preventing reinjury.

Impact of the s.w.e.a.T.™ water-exercise method on activities of daily living for older women.

Older women may have chronic or age-related conditions that increase the risk of falls or that limit their ability to remain active. It is unclear if a water-based exercise program provides a safe and effective alternative to land-based exercise. The purpose of this study was to evaluate the impact of a water-based exercise program method on land-based functional activities of daily living (ADL) for women 60 years and older.

Exercise intensity progression for exercises performed on unstable and stable platforms based on ankle muscle activation.

Ankle sprains are a common sports injury. The literature focuses on the application of neuromuscular training for the improvement of balance, injury prevention and rehabilitation. However, there is a dearth of knowledge about the appropriate prescription of exercises using unstable platforms and surfaces.

Neuromuscular responses during aquatic resistance exercise with different devices and depths.

Little research has been reported regarding the effects of using different devices and immersion depths during the performance of resistance exercises in a water environment. The purpose of this study was to compare muscular activation of upper extremity and core muscles during shoulder extensions performed at maximum velocity with different devices and at different depths. Volunteers (N = 24) young fit male university students performed 3 repetitions of shoulder extensions at maximum velocity using 4 different devices and at 2 different depths.

Concurrent validation of the OMNI-resistance exercise scale of perceived exertion with Thera-band resistance bands.

The concurrent validity of the OMNI-Resistance Exercise Scale (OMNI-RES) of perceived exertion for use with elastic bands was studied during isotonic resistance exercises. Twenty healthy, physically active subjects completed both familiarization and testing sessions. The criterion variables were myoelectric activity, recorded by electromyography, and heart rate, recorded by a heart rate monitor.
