We tested the effect of a home-based respiratory muscle endurance training in patients with mild to moderate generalized myasthenia gravis (MG) on Besinger score, lung function and respiratory muscle endurance. Ten patients performed respiratory muscle endurance training in form of normocapnic hyperpnea training at 50-60% of their maximal voluntary ventilation over 4-6 weeks. MG score, lung fun...

[Purpose] The present study aimed to separately compare systolic blood pressure and diastolic blood pressure with health and fitness-related variables among Asian obese and normal weight middle-aged women. [Subjects and Methods] The study included 1,201 women aged 30-59 years. The participants were classified into obese and normal weight groups. The blood pressure and health and fitness-related...

BACKGROUND Muscular power is an important aspect of many activities of daily living and declines at a faster rate than other fitness parameters (i.e. muscular strength and endurance). Assessing muscular power among older adults is problematic as many of the popular tests are contraindicated among older adults and field tests to assess muscular power among older adults have not been validated am...

CONTEXT Assessment techniques used to measure functional tasks involving active trunk control are restricted to linear movements that lack the explosive movements and dynamic tasks associated with activities of daily living and sport. Reliable clinical methods used to assess the diagonal and ballistic movements about the trunk are lacking. OBJECTIVE To assess the interday reliability of peak ...

Athletes who aim to improve both muscular endurance and power often perform exercises that involve similar joint actions under different lifting conditions, such as changes in the load or speed, which are implemented at different times during a periodized exercise program or simultaneously. The prescribed exercises are considered to recruit the same muscles even if the lifting conditions differ...

Study I. Participants were 43 Navy men (mean age = 32.1 yr) assigned to one of three exercise training protocols: aerobic/circuit weight training performed at either 40 or 60% of determined one-repetition maximum strength or aerobic/calisthenic training. During the 10-wk study, each exercise group participated in three training sessions per week performed on alternate days. The results of this ...

Introduction Endurance of the back muscles is considered as an important contributing factor in the development of low back pain. Currently, researchers are looking at reliable methods for measuring the back muscle’s fatigue rate by surface electromyogram (EMG). Many of these studies are still at the experimental stage and the feasibility of using EMG as a clinical tool for such purpose remains...

The importance of evaluating the physical fitness future police officers cannot be underestimated. Ideal training program must include targeting aerobic capacity, anaerobic power, muscular strength and endurance. aim study: investigate impact two additional supervised 16-week programs (mixed (jumping + endurance) workout CrossFit training) aimed at female cadets. Participants: relatively health...

The purpose of this study was to compare the effects of a protocol employing a combination of loading zones vs. one employing a constant medium-repetition loading zone on muscular adaptations in resistance-trained men. 19 trained men (height=176.9±7.0 cm; body mass=83.1±11.8 kg; age=23.3±2.9 years) were randomly assigned to 1 of 2 experimental groups: a constant-rep resistance training (RT) rou...

[Purpose] The purpose of this study was to examine whether an aerobic interval exercise using an eccentric contraction would result in skeletal muscular hypertrophy and augmentation of muscular strength in rats. [Subjects and Methods] Twenty-one female Wistar rats were used in this study. The rats were randomly divided into three groups. The control group performed no exercise. The aerobic endu...
