Two cosmonauts who spent a year in space suffered fewer physical effects than expected, and there do not appear to be any barriers to even longer missions, Soviet space specialists said. Anatoly Grigoryev, director of the Institute of Bio-Medical Problems, told a news conference that cosmonauts Musa Manarov and Vladimir Titov, who returned to Earth on Dec. 21, suffered some atrophy of their calf muscles and some loss of calcium, as have other cosmonauts. But because of exercise and training developed by Soviet scientists, the effects suffered by Manarov and Tito were less severe than their predecessors, he said.
