It is known that non-cachectic patients with chronic obstructive pulmonary disease (COPD) respond well to rehabilitation, but whether cachectic COPD are capable of adaptive responses both important and unknown. 10 19 undertook high-intensity cycling training, at the same relative intensity, for 45 min·day −1 , 3 days·week weeks. Before after rehabilitation vastus lateralis muscle biopsies were analysed morphologically expression remodelling factors (insulin-like growth factor (IGF)-I,...
Myosin heavy chain (MHC) isoform composition was determined in 2264 single skeletal muscle fibers from vastus lateralis of a group (n = 12) very old subjects (average age, 88 years). The number containing only MHC I, IIA, or IIX 19.9%, 27.2%, and 0.3%, respectively. Surprisingly, 28.5% the displayed coexpression both I phenotype that is present younger adults small percentages. Among these coexpressing majority had dominant expression I. Additionally, without any all three isoforms were...
The profiles of the lactate/H+ transporter isoforms [monocarboxylate (MCT)] MCT1 and MCT4 (formerly MCT3 Price, N. T., V. Jackson, A. P. Halestrap. Biochem. J. 329: 321-328, 1998) were studied in soleus, triceps brachii, vastus lateralis muscles six male subjects. fiber-type compositions evaluated from occurrence myosin heavy chain isoforms, fibers classified as type I, IIA, or IIX. total content was determined muscle homogenates by Western blotting, visualized on cross-sectional sections...
<h3>Background:</h3> Skeletal muscle wasting commonly occurs in patients with chronic obstructive pulmonary disease (COPD) and has been associated the presence of systemic inflammation. This study investigated whether rehabilitative exercise training decreases levels or local inflammation reverses abnormalities deconditioning. <h3>Methods:</h3> Fifteen COPD (mean (SE) forced expiratory volume 1 s 36 (4)% predicted) undertook high-intensity 3 days/week for 10 weeks. Before after programme...
The rate of force development (RFD) is an essential component for performance in explosive activities, although it has been proposed that muscle architectural characteristics might be linked with RFD and power performance. purpose the study was to investigate relationship between RFD, architecture, young track field throwers. Twelve throwers completed 10 weeks periodized training. Before (T1) after (T2) training evaluated competitive throws, commonly used shot put tests, isometric leg press...
Chronic aerobic exercise training is associated with improved endothelial function and arterial stiffness favourable long-term cardiovascular effects.We investigated the acute effects of continuous moderate intensity (CAE) high interval (hIAE) on in healthy participants.Twenty men were recruited to this cross-over study. They participated two sessions: (a) CAE, volume at 50% maximum work for 30 minutes; (b) hIAE, minutes. Endothelial was evaluated by flow-mediated dilation brachial artery....
The aim of this study was to explore the relationship between muscle fiber conduction velocity (MFCV), type composition, and power performance in participants with different training background.Thirty-eight young males background participated: sedentary (n = 10), endurance runners 9), trained strength 9). They performed maximal countermovement jumps (CMJ) isometric leg press for measurement rate force development (RFD). Resting vastus lateralis MFCV measured intramuscular microelectrodes on...
Abstract The effects of high intensity interval training (HIIT) frequency on cardiometabolic health and quality life were examined in 35 healthy inactive adults (age: 31.7±2.6 yrs, VO2peak: 32.7±7.4 ml·kg−1 ·min−1). Participants randomly assigned to a control (CON) two groups, which performed 10×60-s cycling at ~83% peak power, (HIIT-2) or three times per week (HIIT-3) for eight weeks. Compared with CON, both regimes resulted similar improvements VO2peak (HIIT-2: 10.8%, p=0.048, HIIT-3:...

J Strength Cond Res 28(9): 2521–2528, 2014—This study investigated the effects during (half-squat) subsequent vertical jump performance. Fourteen track field athletes (relative half-squat 2.3 ± 0.3 times their body weight) completed 4 main trials in a randomized counterbalanced order 5–7 days apart: (a) concentric (CON)...

J Strength Cond Res 33(3): 633-640, 2019-This study compared the effects of performance, maximal strength, rate force development (RFD). Fifteen moderately trained subjects were randomly assigned to either a (U, n = 7) or group (B, 8). Both groups performed effort leg exercises 2 times per week for 6...
The aim of the study was to investigate rate force development (RFD) and muscle architecture early adaptations in response training with fast- or slow-velocity eccentric squats. Eighteen young novice participants followed six weeks (two sessions/week) either fast-velocity (Fast) (Slow) squat eccentric-only training. Fast consisted nine sets repetitions at 70% 1-RM <1 s duration for each repetition. Slow five 90% ~4 sec Before after training, 1-RM, countermovement jump (CMJ), isometric leg...
This study examined the effects of high-volume static stretching training on gastrocnemius muscle architecture, ankle angle and jump height in 21 female adolescent volleyball players. Static plantar flexors one leg (STR) was performed five times/week for 12 weeks, addition to training, with contra-lateral used as control (CON). Total duration per session increased from 540 s (week 1) 900 12). At baseline, week after 3 weeks detraining, architecture at middle distal part both heads (medialis...
Aim of the study was to investigate whether high-intensity interval cycling performed immediately after resistance training would inhibit muscle strength increase and hypertrophy expected from per se. Twenty-two young men were assigned into either (RE; N = 11) or plus (REC; 11). Lower body rate force development (RFD), quadriceps cross-sectional area (CSA) vastus lateralis architecture, fiber type composition capillarization, estimated aerobic capacity evaluated before 8 weeks (2 times...
Abstract Methenitis, S, Spengos, K, Zaras, N, Stasinaki, A-N, Papadimas, G, Karampatsos, Arnaoutis, and Terzis, G. Fiber type composition rate of force development in endurance- resistance-trained individuals. J Strength Cond Res 33(9): 2388–2397, 2019—The purpose the study was to investigate relationship between muscle fiber (RFD) well-trained individuals with different training background. Thirty-eight young men background participated: 9 endurance runners, 10 power-trained individuals,...
The aim of the study was to examine correlation between muscle morphology and jumping, sprinting, throwing performance in participants with different power training duration experience. Thirty-six power-trained young men were assigned 3 groups according length their training: less experienced (<1 year), moderately (1-3 years), (4-7 years). All performed countermovement squat jumps, 60-m sprint, shot throws twice. Lean body mass (LBM) evaluated dual-energy x-ray absorptiometry thigh...
