objective: to compare the effects of aerobic and stretching exercises on severity of primary dysmenorrhea. materials and methods: this randomized clinical trial was conducted on 105 female students who were suffering from primary dysmenorrhea. the participants were divided into aerobic exercise, stretching exercise, and control groups. the two intervention groups did the exercises three times a...

abstract background: hypertension in pregnancy is one of the prevalent disorders resulting in maternal death. the aim of this study was to investigate the effect of stretching exercise and walking on changes of blood pressure in nulliparous women during pregnancy. materials and methods: this was a quasi-experimental trial that consisted three groups of women who took part in pre- and post-tests...

methods in this study, 16 skilled female gymnasts (mean age of 9.62 ± 1.45 years) were randomly categorized to two general warm-up with no stretching (ns, n=8) and general warm-up plus static stretching (ss, n=8) groups. the warm-up protocol included a 10-minute jogging, and the static stretch (ss) protocol included stretching programs on the different parts of body during four weeks, three tim...

conclusions the results highlighted the significance of training and performing the stretching exercises during dialysis for the purpose of improving restless legs syndrome symptoms and the quality of care of hemodialysis patients. results the results showed that the majority of participants were suffering from moderate restless legs syndrome. the symptom severity of this syndrome meaningfully ...

This study examined the effects of baseline flexibility and vertical jump ability on straight leg raise range of motion (ROM) and counter-movement jump performance (CMJ) following different volumes of stretching and potentiating exercises. ROM and CMJ were measured after two different warm-up protocols involving static stretching and potentiating exercises. Three groups of elite athletes (10 ma...

The purpose of this study was to compare three warm-up protocols--static stretching, dynamic stretching, and light aerobic activity--on selected measures of range of motion and power in untrained females and to investigate the sustained effects at 5 and 30 minutes after warm-up. A total of 24 healthy females (ages 23-29 years) attended one familiarization session and three test sessions on nonc...

Int J Exerc Sci 3(4) : 214-224, 2010. This study examined the effects of single set dynamic and static stretching on vertical jump height and hip and knee range of motion in a sample of college age recreational males. Forty-two healthy, physically active males (aged 18-24) voluntarily participated in this investigation and were randomly assigned to one of three groups (1 set of 20 seconds dynam...

Warming up before performing rigorous physical activity is typically done to increase range of motion and improve athletic performance. Common warm-up techniques in college athletics include static stretching, proprioceptive neuromuscular facilitation (PNF) stretching, dynamic warm-ups, and sport-specific activities. However, the type of warm-up routine used in the college setting varies based ...

This study aimed to compare the effect of different static stretching durations followed by dynamic stretching on repeated sprint ability (RSA) and change of direction (COD). Twenty-five participants performed the RSA and COD tests in a randomized order. After a 5 min aerobic warm up, participants performed one of the three static stretching protocols of 30 s, 60 s or 90 s total duration (3 str...

The purpose of this study was to compare the acute effects on youth fitness of 3 different warm-up protocols utilizing static stretching or dynamic exercise performance. Sixty children (mean age 11.3 +/- 0.7 years) performed 3 different warm-up routines in random order on nonconsecutive days. The warm-up protocols consisted of 5 minutes of walking and 5 minutes of static stretching (SS), 10 min...
