There were increases in the range of motion were seen throughout the treatment groups, PNF stretching
techniques were found to be more effective than the stretching done with static method for both hip flexion and shoulder extension.
Robot-assisted PNF stretching
is effective for injured ankles.
Whereas the same amount of antagonist static stretching produced significant increases in the agonist muscles (Miranda et al., 2015), no significant differences were observed following antagonist PNF stretching
(Paz et al., 2012) during seated row resistance exercise test.
(19-21) Common types of passive flexibility training programs are static stretch and some PNF stretching
is a stretching technique that is usually done with a partner.
Wallin et al (1985) investigated the effect of 30 days of proprioceptive neuromuscular facilitation (PNF) and ballistic stretching, and 30 days of on-going PNF stretching
with different stretching frequencies from one to five times a week.
Effects of PNF stretching
phases on acute arterial blood pressure.
, or proprioceptive neuromuscular facilitation, is a method of flexibility training that can reduce hypertonus, allowing muscles to relax and lengthen.
Verrall et al's investigation  added interventions like PNF stretching
, sport specific training and anaerobic training.
Then, they performed 2 sets of PNF stretching
for the pectoral and biceps muscles, with 6 sec of isometric contraction followed by 24 sec of sustained stretching (1).
(proprioceptive neuromuscular facilitation)--performing a stretch and then contracting the muscle.
Active and PNF stretching
, however, which involve progressive muscle contraction and specific patterns of movement against external loading over the full range of movement, seem to offer the most effective means of improving the full range of functional performance in sport (running) and exercise.
