To (1) determine if wearing a cloth face mask significantly affected exercise performance and associated physiological responses, (2) describe perceptual measures of effort participants' experiences while during maximal treadmill test.Randomised controlled trial healthy adults aged 18-29 years. Participants completed two (with without mask) cardiopulmonary tests (CPETs) on following the Bruce protocol. Blood pressure, heart rate, oxygen saturation, exertion shortness breath were measured....
Resistance exercise intensity is commonly prescribed as a percent of 1 repetition maximum (1RM). However, the relationship between 1RM and number repetitions allowed remains poorly studied, especially using free weight exercises. The purpose this study was to determine maximal that trained (T) untrained (UT) men can perform during exercises at various percentages 1RM. Eight T 8 UT were tested for strength. Then, subjects performed set failure 60, 80, 90% in back squat, bench press, arm curl...

Exercise-Induced Muscle Damage (EIMD) and delayed onset muscle soreness (DOMS) impact subsequent training sessions activities of daily living (ADL) even in active individuals. In sedentary or diseased individuals, EIMD DOMS may be more pronounced present the absence structured exercise.The purpose this study was to determine effects oral curcumin supplementation (Longvida® 400 mg/days) on & ADL soreness, creatine kinase (CK), inflammatory cytokines (TNF-α, IL-6, IL-8, IL-10) following EMID...

Effects of stretching on upper-body muscular performance. J Strength Cond Res 22: 1279-1285, 2008-The purpose this investigation was to examine the influence static dynamic Eleven healthy men, who were National Collegiate Athletic Association Division I track field athletes (age, 19.6 ± 1.7 years; body mass, 93.7 13.8 kg; height, 183.6 4.6...
Previous research has demonstrated that ingestion of essential amino acids and their metabolites induce anabolic effects with the potential to augment gains in lean body mass strength after resistance exercise training.The purpose present study was examine an acid-based formula (Muscle Armor (MA); Abbott Laboratories, Park, IL) containing beta-hydroxy-beta-methylbutyrate (HMB) on hormonal muscle damage markers response 12 wk exercise.Seventeen healthy men (mean mass: 77.9 +/- 7.2 kg; mean...
The purpose of this study was to present a profile body size and composition National Football League (NFL) players prior the start regular season. Fifty-three members Indianapolis Colts professional football team were measured for height, mass, percentage fat using BOD POD air-displacement plethysmography system during summer camp 2003 These data categorized by position comparison with previous studies NFL players. relationships observed as follows (= represents nonsignificant; > p < or =...
The purpose of this study was to examine changes in body composition (BC) and physical performance tests (PT) resulting from a competitive season soccer. Twenty-five male collegiate players (age = 19.9 +/- 1.3 years; height 177.6 6.4 cm; mass 77.6 8.6 kg, percentage fat 12.8 5.2%) were tested before (PRE) after (POST) the 2003-2004 National Collegiate Athletic Association season. following performed: BC (anthropometric dual energy x-ray absorptiometry measurements), vertical jump (VJ), 9.1-m...
The purpose of this study was to determine the impact a very slow (VS) velocity and self-selected volitional (VOL) at varying intensities on repetition number, peak force, power, total volume in squat shoulder press exercises. On separate testing days, 9 resistance trained men (age: 23.9 +/- 2.5 years; height: 174.8 6.5 cm; body mass: 80.1 12.4 kg) performed (SQ) (SP) exercise 60 or 80% 1 maximum (1RM) either VOL VS (10-second eccentric 10-second concentric actions) for as many repetitions...
The order of resistance exercises within a training session may have vital impact on the quality constituent performed. However, very few studies documented specific influence exercise order. Therefore, purpose this study was to examine effect back squat performance in context whole-body workout. Nine resistance-trained male subjects (age: 24 +/- 4 years, body mass: 81.5 15.3 kg, resistance-training experience: 7 years) performed (4 sets at 85% 1 repetition maximum) 2 separate occasions...
The purpose of this study was to verify the concurrent validity a bar-mounted Myotest® instrument in measuring force and power production squat bench press exercises when compared gold standard computerized linear transducer platform system. Fifty-four men (bench press: 39-171 kg; squat: 75-221 kg) 43 women 18-80 30-115 (age range 18-30 years) performed 1 repetition maximum (1RM) strength test exercises. Power testing consisted jump throw at 30% each subject's 1RM. During measurement, both...
Resistance exercise can acutely increase the concentrations of circulating neuroendocrine factors, but effect mode on this response is not established. The purpose study was to examine resistance selection acute hormonal using similar lower-body multijoint movement free weight and machine exercises. Ten trained men (25 ± 3 years, 179 7 cm, 84.2 10.5 kg) completed 6 sets 10 repetitions squat or leg press at same relative intensity separated by 1 week. Blood samples were collected before...
Context: The sensation of thirst is different from the complex behavior drinking ad libitum. Rehydration recommendations to athletes differ, depending on source, yet no previous researchers have systematically compared (DTT) versus libitum (DAL). Objective: To compare 2 groups trained cyclists (DTT and DAL) who had similar physical characteristics training programs (P &gt; .05). DTT group (n = 12, age 47 ± 7 years) drank only when thirsty, whereas DAL 44 consumed fluid (ie, whenever in...
