Lack of Evidence for Non-Local Muscle Fatigue and Performance Enhancement in Young Adults
نویسندگان
چکیده
Post-activation performance enhancement (PAPE) is an improvement to voluntary muscle following a conditioning activity. There evidence of fatigue resistance deficits in non-exercised muscles unilateral fatiguing exercise contralateral muscle. The purpose this study was determine if protocol could induce PAPE contralateral, young healthy adults. Thirty-two recreationally trained (n = 16) and athletically participants (16 males; age: 22.9 ± 2.03 years; height: 1.81 0.06 m; weight: 82.8 9.43 kg, 16 females; 23.1 2.80 1.67 0.07 66.4 11.09 kg) were randomly allocated into two groups (dominant or non-dominant limb intervention). experimental intervention, involved (4-repetitions 5-seconds knee extension maximal isometric contractions: MVIC) with either the dominant (DOM) (ND) extensors testing same (exercised) (non-exercised) leg as well control (no exercise: n 32) condition. Testing performed before, 1-minute 10-minutes after high intensity, low volume, (2 sets 2x5-s MVIC). Pre- post-testing included MVIC force F100 (force developed first 100 ms: proxy measure rate development) drop jump (DJ) height contact time. no significant peak EMG nor DJ time interactions (intervention x dominance time). pre-test (0.50 0.13) forces exceeded (p 0.02) both post-test post-10 min by small magnitude 8.7% (d 0.31). also intervention although it observed that condition likely demonstrate large changes legs. Following activity, there for non-local improvements (PAPE), decreases.

The purpose of this study was to investigate the relationship between sprint performance of front-crawl swimming and muscle fascicle length in 23 male young swimmers. The sample was divided into two groups by 25-m sprint front-crawl swimming performance: 14.6-15.7 s (S1, n=11) and 15.8-17 s (S2, n=12). Muscle thickness and pennation angle and fascicle length of the Biceps Brachii (only muscle t...

OBJECTIVE Noncompaction cardiomyopathy or left ventricular noncompaction is a rare disease that is probably underdiagnosed. The diagnosis is reached by echocardiography, although MRI provides additional morphological and functional information. Late MRI enhancement is a hallmark of the disease that reflects fibrosis or infarction of affected areas in adults and older children. We aimed to revie...
