STUDY DESIGN Case report. OBJECTIVE To highlight the effects of an intervention program consisting of strengthening and neuromuscular reeducation of the gluteus maximus in an elite triathlete with exercise-associated muscle cramping (EAMC). BACKGROUND Researchers have described 2 theories concerning the etiology of EAMC: (1) muscle fatigue and (2) electrolyte deficit. As such, interventions...

OBJECTIVES The aim of this work was to explore the physiological and perceptual limits to exercise in children with varying degrees of motor impairment, and the relationships to measures of health. DESIGN AND METHODS In a group comparison design, 35 boys aged 12-15 years completed the Movement ABC test for the assessment of motor impairment, followed by an incremental cycle ergometer test to ...

INTRODUCTION Muscle weakness determines functional impairment in spastic cerebral palsy (SCP). Measurement of specific force (SF) allows for strength comparison with unimpaired populations (controls) accounting for neural (activation and coactivation), architectural (fascicle length and pennation angle), and structural differences (moment arm length). METHODS Medial gastrocnemius (MG) SF (and...

The purpose of the present study was to evaluate the effects of a trunk exercise program on the gait and muscle activity in stroke patients. The participants of this pilot study included six hemiplegic stroke patients. The outcomes were surface electromyography (sEMG) and spatiotemporal gait parameters. In analysis of sEMG, no statistically difference was found between preand post-training of M...

[Purpose] The purpose of this study was to compare the upper, middle, and lower trapezius muscles' activity in the different planes of shoulder elevation. [Subjects] Twenty male subjects volunteered for this study. [Methods] Surface electromyographic (EMG) activity for each of the three regions of the trapezius muscles in the three different planes of elevation were collected while the particip...

Hamstring muscle function during knee flexion has been linked to hamstring injury and performance. However, it is unclear whether alone (KF) requires similar electromyography (EMG) activity pattern simultaneous hip extension (HE-KF), a combination that occurs in the late swing phase of sprinting. This study examined HE-KF maximal voluntary isometric contraction (MVIC) evokes higher biceps femor...

Abstract Study aim : This study investigated the effect of taurine supplementation on exercise performance and recovery from resistance exercise. The was conducted with a cross-over design in double-blind manner. Material methods Ten trained males (age 21.4 ± 2.01 years; BMI: 23.6 2.5 kg/m²) ingested either (0.1g/kg) supplement or placebo (18 mg aspartame) prior to Vertical jump, flexibility, b...

Neuromuscular electrical stimulation (NMES) may be used to prevent strength loss associated with post-surgical immobilization. Most studies testing the effectiveness of NMES have trained the knee extensors. The purpose of this investigation was to test the effectiveness of NMES when training the elbow flexors. Twenty-four students were randomly assigned to one of three groups: NMES training, is...

BACKGROUND Previous research has identified some specific exercises to correct scapular muscle balance and onset timing in healthy subjects. However, evidence for their effectiveness in overhead athletes with impingement symptoms has been lacking until now. HYPOTHESIS A 6-week exercise program consisting of previously selected exercises is able to improve muscle activation and onset timing du...

Abstract The New Horizons encounter with the Pluto system revealed to have an extremely spatially variable surface expansive dark, bright, and intermediate terrains, refractory volatile ices, ongoing/recent endogenous exogenous processes. Albedo is useful for understanding transport because it quantifies absorbed solar energy; albedo may also provide insights into Four filters of LORRI MVIC ima...
