The purpos of this study was to determine the effect of  twelve session of high intensity cycle training with blood flow restriction on aerobic and anaerobic performance of active student men. To this purpose, 24 valentear active students men from physical eduction faculty of kharazmi university aged 19-23 years old, students (mean ± SD weight: 67.89±6 kg, height: 173.92±5.41cm, and  BMI: 22.7±...

We consider a game-theoretic bin packing problem and we study the convergence time to a Nash equilibrium. We show that, if the best-response strategy is used, then the number of steps needed to reach Nash equilibrium is O(mw2 max + nwmax) and O(nkwmax), where n, m, k and wmax denotes, resp., the number of items, the number of bins, the number of distinct item sizes, and the size of a largest item.

Soil is a complex habitat where microarthropods, such as mites (Acari) and springtails (Collembola) species occur in high number diversity. Microarthropods play an essential role organic matter decomposition provide important ecosystem service soil. The soil-dwelling microarthropods are sensitive to environmental changes; therefore, their ecological characteristics used evaluate soil conditions...

Here we report on the effect of combining endurance training with heavy or explosive strength training on endurance performance in endurance-trained runners and cyclists. Running economy is improved by performing combined endurance training with either heavy or explosive strength training. However, heavy strength training is recommended for improving cycling economy. Equivocal findings exist re...

Thorup and Zwick, in the seminal paper [Journal of ACM, 52(1), 2005, pp 1-24], showed that a weighted undirected graph on n vertices can be preprocessed in subcubic time to design a data structure which occupies only subquadratic space, and yet, for any pair of vertices, can answer distance query approximately in constant time. The data structure is termed as approximate distance oracle. Subseq...

OBJECTIVE This study sought to derive generalized equations for predicting maximal workload for young men and women. METHODS Direct ergospirometry (Aerosport TEEM 100, USA) was used to determine VO2máx and the maximal work load (Wmax) on the cycle ergometer test (Monark,Brazil) of thirty men (25 +/- 5 years, 75.0 +/- 10.7 kg; 48.4 +/- 8.8 mL x kg(-1) x min(-1) and 243 +/- 51 Watts) and thirty...

Aerobic exercise is typically associated with expansion of the mitochondrial protein pool and improvements in muscle oxidative capacity. The impact of aerobic exercise intensity on the synthesis of specific skeletal muscle protein subfractions is not known. We aimed to study the effect of aerobic exercise intensity on rates of myofibrillar (MyoPS) and mitochondrial (MitoPS) protein synthesis ov...

Scheduling problems are fundamental in combinatorial optimization. Much work has been done on approximation algorithms for NP-hard cases, but relatively little is known about exact solutions when some part of the input is a fixed parameter. In 2014, Mnich and Wiese initiated a systematic study in this direction. In this paper we continue this study and show that several additional cases of fund...

OBJECTIVES This study investigated the influence of a moderate caffeine dose on endurance cycle performance and thermoregulation during prolonged exercise in high ambient temperature. DESIGN Double-blind cross-over study. METHODS Eight healthy, recreationally active males (mean±SD; age: 22±1 years; body mass: 71.1±8.5kg; VO2peak: 55.9±5.8mLkg-1min-1; Wmax: 318±37W) completed one VO2peak tes...
