....

..In addition, the effect of the pre-exercise drink on subjective feelings of energy, fatigue, alertness and focus was also explored...

....

..The sensible integration of different training methods along with the periodic manipulation of programs design variables over time will keep the training stimulus effective, challenging, and enjoyable for the participants...

..This article builds on previous recommendations from the NSCA and should serve as the prevailing statement regarding youth resistance training. It is the current position of the NSCA that:..

..Strategies for enhancing the safety of youth resistance training are discussed...

..4 +/- 5.4 seconds) after AE, RT, BS, or the control day, respectively. These findings suggest that an exercise lesson or skill-based PE class will not have an adverse effect on after-school fitness performance in adolescent athletes...

..The results of this study support the inclusion of ballistic exercises into a heavy resistance training program for increasing 1RM bench press and enhancing lower-body power...

..These results indicated that a supplement consisting of amino acids, creatine, taurine, caffeine, and glucuronolactone can modestly improve high-intensity endurance; however, the anabolic-hormonal response was not augmented...

..However, these performance gains did not affect the acute endocrine response to the exercise stimulus...

..However, higher training volumes and lower subjective feelings of fatigue in BA indicated that as duration of supplementation continued, the efficacy of beta-alanine supplementation in highly trained athletes became apparent...

....

..Results indicate that a proprietary protein SUP consumed before and after a resistance training session significantly contributes to improvements in exercise recovery 24 and 48 h post-exercise...

....

....

..These findings suggest that regular participation in recreational sports throughout the year may be associated with higher levels of muscular strength and anaerobic power in children...

..These findings indicate that boys and teens are better able to maintain muscle performance during intermittent moderate-intensity resistance exercise as compared with men...

..The results of this study do not provide support for protein intakes greater than recommended levels in collegiate strength/power athletes for body composition improvements, or alterations in resting hormonal concentrations...

..The results of this study suggest that it may be desirable for children to perform moderate- to high-intensity dynamic exercises prior to the performance of activities that require a high power output...

..Changes in biochemical indices of muscle damage and hormonal markers of stress were examined during a competitive intercollegiate football season...

....

..The largest reductions in performance occurred with very short RI (<1 min), and performance was maintained during the first 3-4 sets when 3- and 5-min RI were used...

..In conclusion, the use of 2- and 3-inch thick bars may result in initial weight reductions primarily for pulling exercises presumably due to greater reliance on maximal grip strength and larger hand size...

..44). Results suggest that increases in MDA occur independently of exercise intensity, but tissue acidosis may have a larger influence on MDA formation...

..Reversing the order or increasing the magnitude of intensity fluctuation would not further alter metabolic consequences...

..04) and P (0.83 +/- 0.03), but not following endurance exercise. A nutritionally-enriched coffee beverage appears to enhance time to exhaustion during aerobic exercise, but does not provide an ergogenic benefit during anaerobic exercise...

..37, p<0.05) sides. Although power performance in the nondominant leg appears to correlate to agility performance, bilateral power deficits do not appear to relate to performance differences during direction-specific agility tests...

..In addition, this supplement also appears to affect cardiovascular dynamics by augmenting systolic arterial blood pressure...

..Women oxidized more fat than men at 40% VO(2)peak, but this gender difference did not occur at higher intensities. It appears that exercising within the moderate intensity domain will produce similar rates of fat utilization...

....

..The enhanced exercise performance resulted in a significantly greater increase in both growth hormone and insulin concentrations, indicating an augmented anabolic hormone response to this pre-exercise S...

..In addition, the osteocalcin response to short-term resistance training appeared to be affected by protein intake...

..A secondary purpose of the study was to investigate the knowledge, beliefs, and sources of education on nutritional supplementation and AS in these students...

..Results indicate that the time of protein-supplement ingestion in resistance-trained athletes during a 10-wk training program does not provide any added benefit to strength, power, or body-composition changes...

..These findings indicate that lower body power performance in male adolescent athletes can be enhanced following DY as compared with SS during the first 18 min of the post warm-up period...

..Of practical significance, treadmill sprint training enhanced land-based sprint performance...

..No gender differences were found for any upper- or lower-body strength test. These findings demonstrate that healthy children can safely perform 1RM strength tests, provided that appropriate procedures are followed...

..The need for replication across ethnic groups was suggested. Limitations and the need for extension of research on supplementation of elementary school PE were discussed...

..In addition, these data suggest that it may be desirable for athletic women to perform dynamic exercises with a weighted vest on some movements prior to the performance of the long jump...

..4% (significant) in CP 1RM. In summary, these data indicate that BMI, handgrip strength, long jump, and vertical jump relate to 1RM strength in children and therefore may be useful for assessing muscular fitness in youths...
