Postactivation potentiation (PAP) is known to enhance force production. Maximal isometric strength assessment protocols usually consist of two or more maximal voluntary isometric contractions (MVCs). The objective of this study was to determine if PAP would influence isometric strength assessment. Healthy male volunteers (n = 23) performed two five-second MVCs separated by a 180-seconds interva...

OBJECTIVE To compare: (i) muscle strength, sprint power and maximal aerobic capacity; and (ii) the correlations between these variables in adults with and without cerebral palsy. DESIGN Cross-sectional study. SUBJECTS Twenty adults with and 24 without cerebral palsy. METHODS Isometric and isokinetic knee extension strength, sprint power (mean power over the 30s (P30)), peak aerobic power ...

BACKGROUND Few interventions reduce patellar tendinopathy (PT) pain in the short term. Eccentric exercises are painful and have limited effectiveness during the competitive season. Isometric and isotonic muscle contractions may have an immediate effect on PT pain. METHODS This single-blinded, randomised cross-over study compared immediate and 45 min effects following a bout of isometric and i...

Combined V-wave and Hoffmann (H) reflex measurements were performed during maximal muscle contraction to examine the neural adaptation mechanisms induced by resistance training. The H-reflex can be used to assess the excitability of spinal alpha-motoneurons, while also reflecting transmission efficiency (i.e., presynaptic inhibition) in Ia afferent synapses. Furthermore, the V-wave reflects the...

Background: PNF stretching is a reputed exercise for the development of physical and sports performance. However, there was no review study on fitness. Aim: The aim to identify effect fitness in perspective positive effect, negative effect. Method: 28 articles fulfilling criteria made this after inclusion exclusion were done. All collected through online scientific data sources. Discussion: Int...

Objective: The aim of this study was to compare functional performance, force sense knee joint, kinesiophobia, quality life, and activity level between patients with partial meniscectomy healthy people.
 Methods: Twenty within six months three years postoperatively 20 were included in study. Maximal voluntary isometric muscle strength Quadriceps femoris the biofeedback device, life Western...

Whey protein is a nutritional supplement commonly ingested for recovery following exercise. However, the timing when whey protein supplement must be ingested after muscle-damaging exercise is debatable. Therefore, the present study investigated the effects of the timing of supplement ingestion on muscle damage markers after eccentric or muscle-damaging exercise. In total, 32 collegiate male stu...

  Background: The Motricity Index was used to measure strength in upper and lower extremities after stroke. The weighted score based on the ordinal 6 point scale of Medical Research Council was used to measure maximal isometric muscle strength. There is dearth of articles dealing with the reliability of this method. Therefore, the aim of this study was to determine the test retest reliability o...

Forty-eight healthy men (M) and women (W), divided into two different age groups, i.e., M50 yrs (range 44-57; n = 12), W50 yrs (range 43-57; n = 12), M70 yrs (range 59-75; n = 12), and W70 yrs (range 62-75; n = 12), volunteered as subjects for examination of muscle cross-sectional area (CSA), maximal voluntary forces, force-time curves, and electromyographic activity of the knee extensor muscle...

The present study was designed to provide further insight into the neuromuscular mechanisms that determine the decrease in maximum strength and strength development of the quadriceps muscle with aging. Different neuromuscular tests were performed in order to assess the neural and muscular changes. The age-related decrease in isometric maximum voluntary torque (iMVT) was accompanied by a decline...
