Abstract

The aim of this study was to determine the effect of 12 weeks of "Tai Chi"
exercise on some of physiological and psychological factors in elderly living in
Nursing Home. In this experimental study, 58 elderly male and female age
69.15±5.3 yr, height 154 ± 0.1 cm and weight 58.13 ±4.4 kg, lived in Sadeghie
Nursing Home were selected and objectively divided in experimental (n=27) and
control groups (n=30). The experimental group trained for 3 month, three
session per/week, and 30 minute in each session. Heart rate, blood pressure,
hands grip strength, flexibility, Berg balance scale, depression and quality of
sleep were measured before and after the exercise program. Data were
analyzed for group differences using covariance test. There was no significant
group difference in heart rate, blood pressure and flexibility. Hands grip
strength, quality of sleep and balance scales were significantly improved and
depression significantly decreased in experimental compared with control
group. So, it seems that using Tai Chi exercise can improve some of
physiological factors, depression and quality of sleep in elderly

Abstract

The aim of this study was to Compare the effect of resistance training with active and passive rest on aerobic
and anaerobic fitness in soccer players. For this purpose 16 players of Foolad Mobarakeh Sepahan club,
accidentally were divided into rest and active group (Height 177.78±6.68 cm, Weight 64.88±7.97 kg, age
18.22±0.83 years ,and percent fat 20.47±1.8) and rest passive group(Height 178.57±6.99 cm, Weight 64±
6.6kg, age 18±0.81 years ,and percent fat 20.05±1.7). The tests were performed in this order: maximal oxygen
consumption, maximal strength, Tmax, muscular endurance, Hoff and RAST test in the pre and post test. The
exercises were done for 8 weeks and twice week with 10 exercises of 30 to 50 percent of maximal strength
with this difference that the active rest group performed 3 sets of 20 repetitions exercise in 30 seconds that rest
interval between 30 seconds was completed with 2 sets of 10 repetitions exercise in 30 second. The passive
group performed 4 sets of 20 repetitions exercise in 30 seconds that rest interval between 30 seconds was
completed with 3 sets passive rest. After determining the normality by Kolmogorov-Smirnov test and
homogenous variance test, independent and dependent t-tests with a significant level of α ≥ 0.05 were used.
The results indicate that after the training period, a significant difference was found in all variables exceptfatigue index in active rest group. But in passive rest group there were a significant difference in variables AT,
vVo2max, Tmax, performance of Hoff test, bench press muscular endurance and leg press strength from pre
test to post test. The results between groups indicated that there was a significant difference between two
groups in Vo2max, Tmax, AT, vVo2max, leg press muscular endurance, and mean power in benefits of active
rest group. Finally, the results showed that the resistance training with active rest causes improvements in
aerobic and anaerobic fitness of soccer players in comparison to resistance training with passive.
