The aim of this study was to determine acute effects of hamstring stretching in thoracic and lumbar spinal curvatures and pelvic tilt. Fifty-five adults (29.24 ± 7.41 years) were recruited for this study. Subjects performed a hamstring stretching protocol consisting of four exercises. The session consisted of 3 sets of each exercise and subjects held the position for 20 seconds with a 30-second...

QUESTION Can passive static stretching lower blood glucose in an at-risk population? DESIGN Randomised, within-participant experimental study. PARTICIPANTS 22 adults (17 males) either at increased risk of Type 2 diabetes or with Type 2 diabetes. INTERVENTION The participants reported to the laboratory 2hr after eating a meal, and drank 355ml of fruit juice (∼43g carbohydrate). Thirty minu...

Background & purpose: Most sports individuals or athletes including tennis players perform stretching during warm-up prior to physical activity in order to prevent injuries and enhance sports performance by improving flexibility. Traditionally static stretching exercises have been a prominent feature of warm up routines. On the other hand, dynamic stretching improves knee joint position sense, ...

Background and Objective. The aim of this study was to investigate the behavior of cells from epithelial rest of Malassez (ERM) against stretching force. Material and Methods. ERM-cultured cells were stretched for 1 hour, at the cycle of 18% elongation for 1 second followed by 1-second relaxation. The cells without addition of stretching force were used as controls. The cells were observed by i...

[Purpose] Degenerative changes take place in the musculoskeletal system of elderly people, resulting in a reduced range of motion. For this reason, stretch training is recommended for elderly individuals. To date, there have been no studies of the adaptations of the passive properties of muscles following long-term stretch training. The aim of this study is to investigate the hamstring elastici...

Proprioceptive neuromuscular facilitation (PNF) is common practice for increasing range of motion, though little research has been done to evaluate theories behind it. The purpose of this study was to review possible mechanisms, proposed theories, and physiological changes that occur due to proprioceptive neuromuscular facilitation techniques. Four theoretical mechanisms were identified: autoge...

Branch-and-Check, introduced ten years ago, is a generalization of logic-based Benders decomposition. The key extension is to solve the Benders sub-problems at each feasible solution of the master problem rather than only at an optimal solution. We perform the first systematic empirical comparison of logic-based Benders decomposition and branchand-check. On four problem types the results indica...

[Purpose] The purpose of this study was to examine the acute effects of five minutes of plantar flexor static stretching (PSS) on the balance and gait of the elderly. [Subjects and Methods] Twenty-five subjects aged 65 years and above performed 5 min of PSS in the form of wedge board standing. The sway length of each subject's center of mass was measured to examine the subject's static balance....

Background It is important to improve the routine ADL(activities of daily living) in the elderly and then diverse and various therapeutic interventions or exercises are applied for the therapy. Generally, to increase the efficiency of the exercise and prevent the injury, the stretching is commonly used [1]. Indeed, there are many case that the elderly complain of the difficulties to control the...
