Periodization is the most effective approach to resistance training; however, optimal cycle lengths for older persons are not known. This study examined the durations of performance increments, plateaus, and decrements in women, ages 61-75 yr, over 9 wk of isokinetic training. After a 2-wk adaptation cycle, older women trained for either power (PWR; 4.73 rad/s; n = 9) or strength (STR; 1.05 rad...

Deposits composed of aragonite prisms, which were formed after the outer shell layer, have been found at the posterior steep slopes of divaricate ribs in two species of Strigilla and another two of Solecurtus. These prisms have their axes oriented perpendicular to the outer shell surface and differ in morphology from fibres of the surface-parallel composite prisms forming the outer shell. They ...

Objective. We examined how parents’ expectations about their infants’ crawling ability and crawling attempts in a locomotor task affect parenting choices about ensuring infants’ safety and providing appropriate challenges. Design. Mothers and fathers of 34 11-month-old infants adjusted a ramp to the steepest slopes they thought their infants could safely crawl down, would attempt to crawl down,...

Hillslopes are thought to poorly record tectonic signals in threshold landscapes. Numerous previous studies of steep landscapes suggest that large changes in long-term erosion rate lead to little change in mean hillslope angle, measured at coarse resolution. New LiDAR-derived topography data enables a finer examination of threshold hillslopes. Here we quantify hillslope response to tectonic for...

Mapping snow in forests is important for understanding the cover dynamics these environments view of hydrological applications and water resources management. Today, Uncrewed Aerial Vehicles (UAVs) are widely used studies due to their rather cheap flexible operation. UAV-borne Light detection ranging (LiDAR) systems a promising technology sub-canopy mapping at high temporal resolutions, concurr...
