High impact information on Weight Lifting

• Muscle strength, assessed by one repetition maximum of weight-lifting exercises increased significantly after testosterone treatment [1].
• A 28-day study was conducted with 13 adult men to determine the effect of weight lifting exercise and protein intake level on urinary 3-methylhistidine (3MH) excretion [2].
• 1. A weight-matching task was used to investigate the ability to estimate heaviness when weight lifting was isolated to the extrinsic flexor muscles (or portions thereof) that act on the digits of the hand [3].
• Cardiovascular tolerance to weight-lifting exercises was evaluated both physiologically and biologically by measuring heart rate (HR) and blood pressures continuously during exercise, and cardiac troponin I (cTnI) blood concentration before and 6 h postexercise [4].
• On the other hand, same day training may enhance increases in CS activity but not VO2max or weight lifting endurance [5].

Biological context of Weight Lifting

• Chromium picolinate supplementation was ineffective in bringing about changes in body composition or strength during a program of intensive weight-lifting training [6].

Associations of Weight Lifting with chemical compounds

• Glucose tolerance and the associated insulin response was assessed using a standard 100-g oral glucose load before and after a supervised 10-wk high-resistance, isotonic weight-lifting program [7].
• Twenty-four postpubertal male albino rats were assigned randomly to sedentary-control (C), endurance-running (ER), and weight-lifting (WL) groups to study the effects of different chronic-exercise regimens on precapillary vascularity in the heart [8].
• Therefore, we concluded that the cortisol level may be considered as a performance factor in weight-lifting [9].
• The 4 week anaerobic training program (two 30-min sessions weight lifting and one interval training per week; lactate levels 4-6 mM and 8-10 mM, respectively), caused a significant increase of the mean arm muscle force by 7% (handgrip test, p < 0.05) [10].
• Groups of rats were either injected daily for 6 weeks with triamcinolone acetonide, 1 mg/kg (group S), subjected to a weight-lifting program 4 times per week (group T), or subjected to the injection and weight-lifting programs concurrently (group ST) [11].

Gene context of Weight Lifting

• The individual changes during this preparatory 4-week training before the primary competition in serum testosterone/SHBG ratio and the individual changes in the weight lifting result in the clean and jerk lift correlated significantly with each other (r = .68; P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)[12]
• Growth hormone responses during intermittent weight lifting exercise in men [13].
• This investigation compared ratings of perceived exertion specific to the active muscles used during resistance exercise (RPE-AM) using the 15-category Borg scale during high-intensity (HIP) and low-intensity (LIP) weight lifting [14].
• Thus, the present results suggested that participation in weight lifting exercises for a long period could increase bone CSA as well as muscle CSA, and induce in the participants a noticeable enlargement in given sites and muscle groups responsible for performing the Olympic lifts [15].
• The purpose of this study was to determine whether high intensity weight lifting exercise produces elevations of urinary 3-methylhistidine (3-MH), serum creatine kinase activity (CK), and serum myoglobin concentration (MY), and whether trained weight lifters differed in such responses when compared to a group of untrained subjects [16].
