Analysis of sports policy in Greece, through a strategic relations perspective 1980-93
The aim of this study is to identify the changing nature of sports policy in
Greece in the period 1980-93. Key themes addressed were the relationship
between policy goals and the political values of the principal political
actors; the impact of the changing nature of the economic and social
structure on policy goals and implementation; and the significance of
national, local and transnational influences and contexts for sports policy.
This study reflects a concern to develop knowledge in this field, in the
sense both that Greek sports policy as an object of study has received little
research attention, and that the framework of strategic relations theory,
which has informed this analysis, has not been employed to date in
investigations of sports policy systems in the literature.
Gathering of data in Greece, incorporated both secondary sources, which
provided aspects of the structural picture of sport, and primary data
derived from interviews, which principally focused on the relations
between actual policy outcomes, the goals of individuals and groups, and
the struggles occurring within the social and political structure. Interviews
were undertaken at various levels within the hierarchies of sports
organisation and of the state.
The principal elements of the concluding analysis in this study were: first,
a focus on political change, from the socialist to right wing government,
which resulted in changes in economic and social policy, which were
themselves reflected in the nature of sports policy; second, a focus on the
position of groups and individuals, and the strategic relations within the
structures which are subject to policy changes; and third, an analysis of
how local, national, and transnational influences have mediated the
context of sports policy in Greece from 1980 to 1993.
Having concluded the analysis of empirical data, a number of key themes
are developed. These include the significance of the political values of the
principal parties on the nature of policy goals at national level; the
evidence of clientelistic relations between central government and
national governing bodies of sport; patterns of corporatism in the relations
between local government and local sporting bodies; and the impact of
political partisanship in the relations between central and local
government and its implications for sports policy at local government
level. The study concludes by reviewing these phenomena within the
context of the conceptual framework implied by strategic relations theory

Blood Pressure Control at Rest and during Exercise in Obese Children and Adults
The hemodynamic responses to exercise have been studied to a great extent over the past decades, and an exaggerated blood pressure response during an acute exercise bout has been considered as an indicator of cardiovascular risk. Obesity is a major factor influencing the blood pressure response to exercise since evidence indicates that the arterial pressure response to exercise is exacerbated in obese compared with lean adults. Signs of augmented responses (such as an exaggerated blood pressure response) to physical exertion appear early in life (from the prepubertal years) in obese individuals. Understanding the mechanisms that drive the altered hemodynamic responses during exercise in obese individuals and prevent the progression to hypertension is vitally important. This paper focuses on the evidence linking obesity with alterations of the autonomic nervous system and discusses the potential mechanisms and consequences of the altered sympathetic nervous system behavior in obese individuals at rest and during exercise. Furthermore, this paper presents the alterations in the reflex regulatory mechanisms (“exercise pressor reflex” and baroreflex) in obese children and adults and addresses the effects of training on obesity-related disturbances

Effects of acute postexercise chocolate milk consumption during intensive judo training on the recovery of salivary hormones, salivary SIgA, mood state, muscle soreness, and judo-related performance
This study examined the effects of postexercise chocolate milk (CM) or water (W) consumption during 5 days of
intensive judo training with concomitant weight loss on salivary cortisol and testosterone, salivary secretory immunoglobulin
A (SIgA), delayed-onset muscle soreness (DOMS), and judo-related performance. Twelve trained male judo athletes engaged in
5 days of intensive judo training followed by a simulated judo competition, on 2 separate training weeks 14 days apart. The
athletes consumed 1000 mL ofW(week 1) or CM (week 2) immediately post-training. During both weeks, athletes were instructed
to “make weight” for the upcoming competition. Performance in timed push-ups and the Special Judo Fitness Test improved by
14.6% and 6.8%, respectively, at the end of the training week with CM consumption (both p < 0.001). Decreased salivary cortisol
(p < 0.01) and a trend for an increased salivary testosterone/cortisol ratio (p = 0.07) were also observed midweek in the CM
condition. Saliva flow rate was higher during the week with CM intake compared withWintake (p < 0.001). DOMS (p < 0.001) and
mood disturbance (p < 0.0001) increased after the first day of training in the W condition but not in the CM condition. Salivary
testosterone and SIgA responses were similar between treatments (p > 0.05). Body mass decreased by 1.9% in theWcondition and
by 1.1% in the CM condition, with no significant difference between treatments. This study indicates that postexercise CM
consumption during short-term intensive judo training enhances aspects of recovery without affecting intentional weight loss
Salivary hormones and anxiety in winners and losers of an international judo competition
The purpose of this study was to investigate the responses of salivary hormones and salivary secretory immunoglobulin A (SIgA) and anxiety in winners and losers during an international judo competition. Twenty-three trained, male, national-level judo athletes provided three saliva samples during a competition day: morning, in anticipation of competition after an overnight fast, mid-competition, and post-competition within 15 min post-fight for determination of salivary cortisol, salivary testosterone, salivary testosterone/cortisol ratio, SIgA absolute concentrations, SIgA secretion rate and saliva flow rate. The competitive state anxiety inventory questionnaire was completed by the athletes (n = 12) after the first saliva collection for determination of somatic anxiety, cognitive anxiety and self-confidence. Winners were considered 1-3 ranking place (n = 12) and losers (n = 11) below third place in each weight category. Winners presented higher anticipatory salivary cortisol concentrations (p = 0.03) and a lower mid-competition salivary testosterone/cortisol ratio (p = 0.003) compared with losers with no differences for salivary testosterone. Winners tended to have higher SIgA secretion rates (p = 0.07) and higher saliva flow rates (p = 0.009) at mid-competition. Higher levels of cognitive anxiety (p = 0.02) were observed in the winners, without differences according to the outcome in somatic anxiety and self-confidence. The results suggest that winners experienced higher levels of physiological arousal and better psychological preparedness in the morning, and as the competition progressed, the winners were able to control their stress response better
Postprandial lipaemia 10 and 34 hours after playing football:Does playing frequency affect the response?
Elevated postprandial triglyceride (TG) is associated with increased risk of cardiovascular disease. The time window for the last bout beneficial effect on postprandial lipaemia after football play is unknown. The aim of the present study was to examine whether playing affects postprandial TG during 1.5 day of reduced activity. Eighteen males were randomly allocated to perform either 1 (1FOOT; n = 9; age = 33.0 ± 5.0 yrs; body mass index = 24.2 ± 3.6 kg/m2) or 3 (3FOOT) consecutive days of 60-min 5 vs 5 football (n = 9; age = 32.8 ± 5.2 yrs; body mass index = 26.2 ± 4.1 kg/m2) matches across a 5-day study period. They arrived to the laboratory 10 hrs and 34 hrs after the final football session and blood samples were collected at fasted (0 min) and 45, 90, 240 and 360 min post a high fat load meal. There were non significant increase for postprandial TG AUC (9.1%; p = 0.17; 95%CI = -0.43 to 2.0; ES = -0.23) and iAUC (14.2%; p = 0.43; 95%CI = -0.92 to 1.9; ES = -0.24) between 10 and 34 hrs after the 1FOOT. For the 3FOOT, there was a non significant decrease in postprandial TG AUC (-2.7%; p = 0.73; 95%CI = -2.0 to 1.5; ES = 0.05) and iAUC (-17.5%; p = 0.41; 95%ci = -2.5 to 1.1; ES = 0.31) from 10 to 34 hrs, respectively. Performing three consecutive days of football exercise may offer no greater protective effect for postprandial TG before a period of reduced activity, compared to a single session
Physical Activity, Screen Time, and Emotional Well-Being during the 2019 Novel Coronavirus Outbreak in China
We aimed to evaluate the effects of the COVID-19 lock down on lifestyle in China during the initial stage of the pandemic. A questionnaire was distributed to Chinese adults living in 31 provinces of China via the internet using a snowball sampling strategy. Information on 7-day physical activity recall, screen time, and emotional state were collected between January 24 and February 2, 2020. ANOVA, χ² test, and Spearman's correlation coefficients were used for statistical analysis. 12,107 participants aged 18-80 years were included. During the initial phase of the COVID-19 outbreak, nearly 60% of Chinese adults had inadequate physical activity (95% CI 56.6%-58.3%), which was more than twice the global prevalence (27.5%, 25.0%-32.2%). Their mean screen time was more than 4 hours per day while staying at home (261.3 ± 189.8 min per day), and the longest screen time was found in young adults (305.6 ± 217.5 min per day). We found a positive and significant correlation between provincial proportions of confirmed COVID-19 cases and negative affect scores (r = 0.501, p = 0.004). Individuals with vigorous physical activity appeared to have a better emotional state and less screen time than those with light physical activity. During this nationwide lockdown, more than half of Chinese adults temporarily adopted a sedentary lifestyle with insufficient physical activity, more screen time, and poor emotional state, which may carry considerable health risks. Promotion of home-based self-exercise can potentially help improve health and wellness.This study was funded by the National Key Technology R&D Program of China (2019YFF0301600),and the National Natural Science Foundation of China (11775059 and 31900845)
The acute effects of different high-intensity conditioning activities on sprint performance differ between sprinters of different strength and power characteristics
The purpose of the present study was to examine the effect of different conditioning activities (CAs) on short-term increase in sprint performance. In twelve male sprinters (21.1±2.6 years, 100 m performance: 11.5±0.6 s) their body composition, half squat maximum strength, 100 m sprinting and countermovement jump performances were evaluated. The performance of a 50 m sprint (splits at 10 m, 30 m and 50 m) was evaluated before and 5, 10 and 15 min after four postactivation performance enhancement CAs on different occasions: [1] 3 sets x 4 s maximum isometric half squat (IHF), [2] 3 sets x 3 consecutive countermovement jumps (cCMJs), [3] 3 repetitions x 30 m overspeed sprinting (OVSP) and [4] dynamic submaximal half squat (2 sets x 2 reps x 90% of 1-RM half squat; HSQ). Significant improvements of sprinting performance were found 10 and 15 min following the cCMJs, OVSP and HSQ’s interventions, in all distances (p.05). Significant inter-individual differences were found in the magnitude of sprint performance improvements as well as in the optimal time window (p<.05), with the stronger sprinters responding better after HSQs, while the more powerful sprinters after cCMJs and OVSPs. In conclusion, it seems that cCMJs, OVSP and HSQ can acutely increase sprinting performance after 10 min, but CA’s induced increases in sprinting performance
are highly related to the strength and power characteristics of each sprinter
