Acute Hemodynamic Responses to Three Types of Hamstrings Stretching in Senior Athletes.

Although stretching is recommended for fitness and health, there is little research on the effects of different stretching routines on hemodynamic responses of senior adults. It is not clear whether stretching can be considered an aerobic exercise stimulus or may be contraindicated for the elderly. The purpose of this study was to compare the effect of three stretching techniques; contract/relax proprioceptive neuromuscular facilitation (PNF), passive straight-leg raise (SLR), and static sit-and-reach (SR) on heart rate (HR) and blood pressure (BP) in senior athletes (119 participants: 65.

Family Subsystems Predicting Adolescents' Perceptions of Sibling Relationship Quality Over Time.

This study examined associations between parents' relationship conflict and parent-adolescent triangulation, and changes in adolescents' perceptions of sibling affection and hostility. The goal was to learn whether conflict in parents' relationships spills over to siblings' relationships, or whether siblings compensate by becoming less hostile and more affectionate. Using a subsample (N = 400) from the Flourishing Families Project (FFP), we found a trend for mother-adolescent triangulation predicting an increase in sibling hostility across 2 years.
