Warm ups , only in your mind? "The effect of warm-ups with stretching on the isokinetic "

The effect of warm-ups with stretching on the isokinetic moments of collegiate men.Performing warm-ups increases muscletemperature and blood flow, which contributes to improved exercise performance and reduced risk of injuries to muscles and tendons. Stretching increases the range of motion of the joints and is effective for the maintenance and enhancement of exercise performance and flexibility, as well as for injury prevention. However, stretching as a warm-up activity may temporarily decrease muscle strength, muscle power, and exercise performance. This study aimed to clarify the effect of stretching during warm-ups on muscle strength, muscle power, and muscle endurance in a nonathletic population. The subjects of this study consisted of 13 physically active male collegiate students with no medical conditions. A self-assessment questionnaire regarding how well the subjects felt about their physical abilities was administered to measure psychological readiness before and after the warm-up. Subjects performed a non-warm-up, warm-up, or warm-up regimen with stretching prior to the assessment of the isokinetic moments of knee joints. After the measurements, the respective variables were analyzed using nonparametric tests. First, no statistically significant intergroup differences were found in the flexor and extensor peak torques of the knee joints at 60°/sec, which were assessed to measure muscle strength. Second, no statistically significant intergroup differences were found in the flexor and extensor peak torques of the knee joints at 180°/sec, which were assessed to measure muscle power. Third, the total work of the knee joints at 240°/sec, intended to measure muscle endurance, was highest in the aerobic-stretch-warm-ups (ASW) group, but no statistically significant differences were found among the groups. Finally, the psychological readiness for physical activity according to the type of warm-up was significantly higher in ASW. Simple stretching during warm-ups appears to have no effect on variables of exercise physiology in nonathletes who participate in routine recreational sport activities. However, they seem to have a meaningful effect on exercise performance by affording psychological stability, preparation, and confidence in exercise performance.<dt style="padding: 0px 0px 0.2em; white-space: nowrap; float: left; width: 30px; color: rgb(0, 0, 0); font-family: arial, helvetica, clean, sans-serif; margin: 0px !important;">

just approved this and another one you posted today. sorry man, not sure why it was moderated

As I have gotten older, I have had to spend a lot more time getting the blood flow into my muscles and joints. A lot of damage over the last 35 years

I have always neglected a thorough warm-up but ALWAYS warm up the shoulders no matter what the day exercises will be. And, always stretch the muscle between my working sets. I find it extremely important for the back workout days, or else eventually those muscles continue to stay in slight tense status and eventually pinch a nerve as weeks/months/years go by and the correction from this point is long and dreadful.

I explain to people that muscle contraction is like Velcro - crossing over and attaching to each other - after contraction the fibers are still holding somewhat and need to be stretched so the muscle can get back to a relaxed state... as well as be ready for a next set.
