Subject: The effect of a progressive athletic activity up to exhaustion on the blood serum’s concentration of two mineral materials (Fe and Zn) in two groups of basketball players and nonathletes. In this research, the effect of a progressive athletic activity on the concentration of two mineral materials (Fe and Zn) was studied. In order to, ten basketball players for experiment and ten nonathlete students for control attended in research. Each examinee was pedaling on the ergometer which measures work with steady speed (60 RPM) and the workload (100 w) and each two minutes increased (50 w) to amount of workload and examinee pedaled to reach to the state of the exhaustion. The previous- bloody samples and immediately after than body test collected and the amount’s Fe, Zn of the blood serum were assessed by spectroscopy atomic absorption in laboratory and collective information were analyzed and resolved by statistical tests of correlated- T test, Independent- T test, Hotelling- T2 test and F test ,and results indicate that the surfaces of two mineral materials of examinee’s blood serum of two groups have found significant decrease after than perform a progressive athletic activity at the level of the confidence(α = 0.05) ,Such as amount of Fe and Zn of the blood serum show excessive decrease, proportionally to opposite series in basketball players and nonathlete students, all of these modifications were in normal range. The lack of these mineral materials have bad effects for body and seem, when these effects become more and more that the stress of physical activity and the combination of the disproportionate nutrition’s diet act together.

Twenty-one overweight or obese individuals (15 females, 6 males; mean BMI = 30.51 ± 2.99 kg.m2), were randomised into either: interval training and diet education (INT group, n = 7); continuous aerobic exercise and diet education (CON group, n = 6); or diet education only (DIET group; n = 8). Baseline and post-intervention testing assessed VO2peak and time to exhaustion during a graded exercise test (GXT) and android and gynoid fat-mass. All participants attended a diet information seminar, while participants in the INT and CON groups cycled 4 times per week over an 8-week period. Interval exercise incorporated a 1:2 min ratio of high intensity (90 – 105% VO2 peak) to low intensity exercise (30 – 45% VO2 peak), while the CON group exercised continuously between 50 – 65% VO2peak. Exercise duration was approximately 30 minutes, with both groups completing the same amount of work. Results showed that both the INT and CONT groups demonstrated significant improvements over time for VO2 peak (p < 0.01 and p = 0.04, respectively) and time to exhaustion on the GXT (p < 0.01 for both groups), while android fat-mass significantly decreased in the INT group only (p = 0.04). A longer intervention period plus changes to interval duration or intensity may have resulted in greater benefits associated with interval exercise.

Ageing is associated with elevated blood pressure and reduced vascular compliance. The aim of this study was to investigate the effect of a regular resistance or flexibility training protocol on the vascular function of men and women aged between 60-75 years. Forty-three generally healthy sedentary elderly participants (20 male; 66 ± 4 years; 78.1 ± 16.0 kg; BMI 27.8 ± 4.4; mean ± SD) took part in the study. The study protocol involved 16 weeks of resistance and 16 weeks of flexibility training in a random crossover design. Each training program involved 2 gymnasium based and 1 home based session per week. Resting heart rate (HR), peripheral and aortic blood pressures, augmentation pressure (AP), augmentation index and subendocardial viability index (SVI) were determined using non-invasive Pulse Wave Analysis (SphygmoCor, AtCorMedical, Australia) prior to and following each training intervention. Following the resistance training protocol there were reductions in resting HR (p = 0.030), ejection duration (p = 0.004), aortic mean pressure (p = 0.030), AP at a constant HR of 75 bpm (p = 0.048) and tension time index (p = 0.004) and an increase in SVI (p = 0.006). Flexibility training also resulted in reductions in resting HR (p = 0.02), and ejection duration (p = 0.02) and an increase in SVI (p = 0.015). The results of the present investigation suggest that either resistance or flexibility training may offset the detrimental effects of ageing on vascular function in the elderly.

National men’s hockey tournaments involve five matches in seven days. Tournament success requires selection of key players for the duration of the tournament. With limited time to recover before the next match and an increased competitiveness as the tournament progresses, key players will experience compounded fatigue. The aim was to describe the effects of this compounded fatigue imposed by tournament conditions through quantifying player work-rates over the tournament. Using Global Positioning System (GPS) monitors, one national squad member (player “A”; midfielder; 20m MSFT level 15:01) and a senior state representative (player B; fullback; 20m MFST level 14:06) were monitored throughout a national tournament. Video analysis was also used as a global measurement of game demands. Slight trends were found for game parameters as the tournament progressed. Time per play and average ball speed both decreased. Ball movements per play were stable whilst duration of ball possession increased. Of the maximum game time (350 minutes) for the tournament, each player spent only a total of 15 minutes on the bench. GPS data showed no clear positional differences for total distance covered, however, player A consistently spent a greater percentage of time at higher running velocities (16 to 21 Km/h and >21Km/h) during each match. Over the tournament, a slight decrease in percentage time spent at these velocities was found for player A, while findings for player B were unchanged. Overall, the GPS data suggests that the players did not show the large hypothesised decrements in work-rates as the tournament progressed.
