One-year periodization of training loads of Russian and Norwegian elite cross-country skiers

The study intended to compare the training load volume (TrV) distribution of elite Russian (RuXC) and Norwegian (NorXC) cross-country skiers in a one-year macrocycle. Daily TrV of 11 RuXC skiers averaged for the period 2014/15–2017/18. The NorXC skiers’ TrV obtained from the study by Sandbakk (2017). RuXC skiers had a lower volume of low-intensity (LIT, below aerobic threshold) and high-intensity (HIT, above anaerobic threshold) endurance training. They used a “pyramidal” model of intensity ratio during the entire macrocycle and did not decrease the volume of moderate-intensity (MIT) endurance training in competition periods (CPs). Conversely, NorXC skiers followed the “pyramidal” model of intensity in the preparation period (PP) but the “polarized” model in CP, significantly reducing the volume of MIT and increasing that of HIT. RuXC skiers increased TrVs more rapidly at the beginning of PPs, achieving TrV peak in June, and then gradually decreased them by March. NorXC skiers increased TrVs gradually by July and then maintained this approximate volume until November. RuXC skiers had peak volumes of LIT and strength training simultaneously in June; NorXC skiers engaged in large amounts of strength training in May and June until reaching maximum endurance loads. RuXC skiers had two “blocks” of strength training; NorXC skiers had three. A comparative analysis of the TrV distributions among the RuXC and NorXC skiers revealed significant similarity. Therefore, they can consider as models of the modern annual periodization of training loads for this kind of sport

Improvement of Corrosion Resistance of Aluminium Coatings at Electric-arc Sputtering with Pulsating Spraying Flow

Annotation: spraying technology is widely used to restore and strengthen worn parts of equipment in machine-building, metallurgical, mining, agricultural industries, which operate in abrasive, shock-abrasive, and gas-abrasive wear conditions and to which new and more stringent requirements are constantly applied. Due to the increasing requirements for the quality and operational resistance of the restored surfaces of parts, the issues of improving the quality of coatings are very relevant for enterprises of various industries.The major disadvantage of arc spraying is the process of oxidation of metal droplets during transportation to the processed surface, which has a significant impact on the quality of the coating and its operational characteristics

Managing withdrawal: Afghanistan as the forgotten example in attempting conflict resolution and state reconstruction

Perhaps surprisingly, given the availability of new Russian memoir material, some excellent individual monographs, and a large variety of declassified documents, a full operational-political account of the Soviet Union's withdrawal strategy from Afghanistan has yet to be written. This article, utilising openly published yet neglected sources, attempts to fill that gap. The final fate of the Najibullah regime, and the contradictory effect of the National Reconciliation Policy in Afghanistan itself, suggests four key lessons for international forces today as disengagement from both Iraq and Afghanistan again becomes a pressing issue, and as questions around re-creating stability within a failed state scenario again occupy the international community
