Resistance exercise can result in localized damage to muscle tissue. This damage may be observed in sarcolemma, basal lamina, as well as, in the contractile elements and the cytoskeleton. Usually the damage is accompanied by release of enzymes such as creatine kinase (CK) and lactate dehydrogenase, myoglobin and other proteins into the blood. Serum CK has(More)
The genetic variability among 13 isolates of Olive mild mosaic virus (OMMV) and of 11 isolates of Tobacco necrosis virus D (TNV-D) recovered from Olea europaea L. samples from various sites in Portugal, was assessed through the analysis of the coat protein (CP) gene sequences. This gene was amplified through reverse transcriptase polymerase chain reaction(More)
The goal of this paper was to investigate the amplitude and sub-100 Hz frequency content of surface electromyography (EMG) signals obtained from agonist, antagonist and synergist muscles during a heel-raise task sustained to failure. Twenty-two healthy adults, 14 men and 8 women participated in the study. Surface EMG data from the raising and lowering(More)
Monitoring and evaluating distributed systems at runtime is a difficult effort. Network traffic analysis may be used to analyse distributed systems, but the capacity to analyse large amount of traffic is a challenge. This work proposes the use of Map Reduce for deeply inspecting distributed systems network traffic, evaluating the effectiveness and the(More)
—Testing, monitoring and evaluation of distributed systems at runtime is a difficult effort, due the dynamicity of the environment, the large amount of data exchanged between the nodes and the difficulty of reproduce an error for debugging. Application traffic analysis is a method to evaluate distributed systems, but the ability to analyze large amount of(More)
Resistance exercise often leads to exercise-induced muscle damage (EIMD). Muscle oedema, muscle soreness, increase in serum creatine kinase (CK) activity, restricted range of motion and strength loss are markers of EIMD. It is well documented that symptoms of EIMD are reduced following a repeated bout of similar exercise, this occurrence has been referred(More)
To examine the effects of different rest intervals between sets on serum creatine kinase (CK) and lactate dehydrogenase (LDH) activity, 10 men (age = 25.6 ± 2.2 years, height = 173.1 ± 7.1 cm, and body mass = 75.9 ± 10.0 kg) participated in a randomized within-subject design that involved 4 resistance exercise sessions. Each session consisted of 4 sets of(More)

PURPOSE The authors tested different loading schemes for the number of repetitions completed during multiple sets of resistance exercise. METHODS Twenty-four resistance-trained men (age 24.0 ± 4.5 y, body mass 78.3 ±10.2 kg, height 177 ± 7 cm) were tested over a 5-wk period. During week 1 a 10-repetition maximum (10RM) in the leg press was determined.(More)
OBJECTIVE The current study examined serum CK activity following bench press (BP) and leg press (LP) exercise-induced muscle damage to evaluate agreement of subjects classification as either high (HiR) or normal responders (NoR) between upper and lower body muscle groups. METHODS Forty-two men performed two resistance exercise bouts (BP and LP) of four(More)
