To compare the effects of high-load, low-repetition maximum (LRM) and low-load, high-repetition maximum (HRM) resistance training regimens on muscular fitness in untrained adolescents. Forty-five untrained adolescents of both sexes (13.7±0.8 years; 161.3±7.5 cm, 56.8±13.4 kg) were randomly assigned into one of three groups: 1) LRM (n = 17): volunteers performed three sets of 4-6-repetition maxi...

In this paper, we present a framework for implementing short-term load forecasting, in which not only conventional statistical time series prediction methods, but also the AI-based ones, can be configured properly. Besides the prediction methods, the forecasting performance also rely heavily on the quality of training data. Therefore, the proposed framework in this paper has two main characteri...

The use of the acute:chronic workload ratio (A/C) has received a growing interest in the past 2 years to monitor injury risk in a variety of team sports. 2 This ratio is generally computed over 28 days (ie, load accumulated during the current week/load accumulated weekly over the past 28 days), using both internal (session-rate of perceive exertion (Session-RPE)×duration) and external (tracking...

The objective of this paper is to compare the performance of different Artificial Neural Network (ANN) training algorithms regarding the prediction of the hourly load demand of the next day in intercontinental Greek power system. These techniques are: (a) stochastic training process and (b) batch process with (i) constant learning rate, (ii) decreasing functions of learning rate and momentum te...

Low-load blood flow restricted (BFR) resistance exercise has been suggested to be as effective as moderate and high-load resistance training for increasing muscle size and strength. The purpose of the study was to evaluate the effects of 6 weeks of HL or low-load BFR resistance training on neuromuscular function, strength, and hypertrophy of the knee extensors. Eighteen participants aged 18-22 ...

PerPot has been developed for modelling, simulating and optimising the interaction between load and performance in training processes in sport but can be used for modelling general physiological adaptation processes as well. The basic idea of PerPot is that a time-dependent load input feeds buffer potentials, from which a performance potential is fed by specifically delayed antagonistic flows (...

BACKGROUND AND PURPOSE Inspiratory muscle weakness and fatigue has been documented following prolonged mechanical ventilation despite successful weaning from mechanical ventilation. This report describes the application of inspiratory muscle training in two patients following successful discharge from an intensive care unit (ICU) after prolonged mechanical ventilation. METHODS Both patients u...

OBJECTIVE To determine whether providing a controlled resistance versus assistance to the paretic leg at the ankle during treadmill training will improve walking function in individuals poststroke. DESIGN Repeated assessment of the same patients with parallel design and randomized controlled study between 2 groups. SETTING Research units of rehabilitation hospitals. PARTICIPANTS Patients ...

A metamodel is introduced, which on one hand can help to understand particular effects and phenomena in the interaction of load and performance in training processes. On the other hand, it can be used as a starting point for refinements to specific adaptation models. Finally, a software tool has been developed that supports different simulation approaches—for example, basic analysis of model pa...

Humans show large and reliable performance impairments when required to make more than one simple decision simultaneously. Such multitasking costs are thought to largely reflect capacity limits in response selection (Welford, 1952; Pashler, 1984, 1994), the information processing stage at which sensory input is mapped to a motor response. Neuroimaging has implicated the left posterior lateral p...
