Research on the Dynamics of the Hormonal Status of Athletes in a Series of Vibration and Traditional Training Exercises

The article presents the most important results of metabolic (hormonal) study of dosed vibration training (DVT).The author presents vibrating training as an alternative to anabolic steroids on the basis of a comparison of the effectiveness of two types of stimulants - forbidden (doping) and non-medicinal non-invasive, relating to permitted physical means.The study shows that the level of androgens (testosterone),corticosteroids (cortisol), thyroid hormones (thyroxine,triiodothyronine),hormones of adenohypophysis (prolactin) increased under the effect of dosed vibration training.At the same time the level of hormones have no changes under traditional strength training with the use of a synthetic anabolic steroid (retabolil).For the duration of a limited period of time (1 microcycles) dosed vibrotraining causes a more powerful secretion of testosterone than the traditional strength training with the use of anabolic steroids. In this case,the overall time spent on the performance of the DVT training program comprises not more than 15% of the time spent on the traditional training exercises.

Comparative efficacy of various exercise interventions on cognitive function in patients with mild cognitive impairment or dementia: A systematic review and network meta-analysis

Background:Exercise is a promising nonpharmacological therapy for cognitive dysfunction,but it is unclear which type of exercise is most effective.The objective of this study was to compare and rank the effectiveness of various exercise interventions on cognitive function in patients with mild cognitive impairment(MCI)or dementia and to examine the effects of exercise on the symptoms relevant to cognitive impairment.Methods:We searched PubMed,Web of Science,Embase,Cochrane Central Register of Controlled Trials,SPORTDiscus,and PsycInfo through September 2019 and included randomized controlled trials that examined the effectiveness of exercise interventions in patients with MCI or dementia.Primary outcomes included global cognition,executive cognition,and memory cognition.Secondary outcomes included activities of daily living,neuropsychiatric symptoms,and quality of life.Pairwise analyses and network meta-analyses were performed using a random effects model.Results:A total of 73 articles from 71 trials with 5606 participants were included.All types of exercise were effective in increasing or maintaining global cognition,and resistance exercise had the highest probability of being the most effective intervention in slowing the decrease in global cognition(standard mean difference(SMD)=1.05,95%confidence interval(95%CI):0.56-1.54),executive function(SMD=0.85,95%CI:0.21-1.49),and memory function(SMD=0.32,95%CI:0.01-0.63)in patients with cognitive dysfunction.Subgroup analyses for patients with MCI revealed different effects,and multicomponent exercise was most likely to be the optimal exercise therapy for preventing the decline of global cognition(SMD=0.99,95%CI:0.44-1.54)and executive function(SMD=0.72,95%CI:0.06-1.38).However,only resistance exercise showed significant effects on memory function for patients with MCI(SMD=0.35,95%CI:0.01-0.69).Exercise interventions also showed various effects on the secondary outcomes.Conclusion:Resistance exercise has the highest probability of being the optimal exercise type for slowing cognitive declin e in patients withcognitive dysfunction,especially in patients with dementia.Multicomponent exercise tends to be most effective in protecting global cognition and executive function in patients with MCI.     

Effects of resistance training performed to repetition failure or non-failure on muscular strength and hypertrophy: A systematic review and meta-analysis

Purpose:We aimed to perform a systematic review and meta-analysis of the effects of training to muscle failure or non-failure on muscular strength and hypertrophy.Methods:Meta-analyses of effect sizes(ESs)explored the effects of training to failure vs.non-failure on strength and hypertrophy.Subgroup meta-analyses explored potential moderating effects of variables such as training status(trained vs.untrained),training volume(volume equated vs.volume non-equated),body region(upper vs.lower),exercise selection(multi-vs.single-joint exercises(only for strength)),and study design(independent vs.dependent groups).Results:Fifteen studies were included in the review.All studies included young adults as participants.Meta-analysis indicated no significant difference between the training conditions for muscular strength(ES=-0.09,95%confidence interval(95%CI):-0.22 to 0.05)and for hypertrophy(ES=0.22,95%CI:-0.11 to 0.55).Subgroup analyses that stratified the studies according to body region,exercise selection,or study design showed no significant differences between training conditions.In studies that did not equate training volume between the groups,the analysis showed significant favoring of non-failure training on strength gains(ES=-0.32,95%CI:-0.57 to-0.07).In the subgroup analysis for resistance-trained individuals,the analysis showed a significant effect of training to failure for muscle hypertrophy(ES=0.15,95%CI:0.03-0.26).Conclusion:Training to muscle failure does not seem to be required for gains in strength and muscle size.However,training in this manner does not seem to have detrimental effects on these adaptations,either.More studies should be conducted among older adults and highly trained individuals to improve the generalizability of these findings.

Longitudinal associations of physical activity and pubertal development with academic achievement in adolescents

Objective: We sought to investigate the longitudinal associations of moderate-to-vigorous physical activity(MVPA) and pubertal development with academic achievement in adolescents.Methods: A total of 635 adolescents(283 boys, 352 girls) aged 11-13 years participated in the study. MVPA was assessed by the Health Behaviour in School-aged Children study questionnaire, and pubertal development was assessed by the Pubertal Development Scale at beginning of the 6 th grade(baseline) and end of the 7 th grade(follow-up). Grade point average(GPA) at the end of Grades 5 and 7 was computed from data acquired from the school registers. The data were analyzed using linear regression and analyses of covariance.Results: In boys, MVPA was positively associated with GPA at baseline after adjustment for age(b = 0.144, 95% confidence interval(CI):0.028-0.260, p = 0.028). In girls, the Pubertal Development Scale was positively associated with GPA at baseline(b = 0.104, 95%CI: -0.004 to0.211, p = 0.058) and follow-up(b = 0.104, 95%CI: -0.002 to 0.211, p = 0.055) after adjustment for age, and these associations strengthened after further adjustment for MVPA(p < 0.05). Adolescents who were inactive at baseline or at baseline and follow-up had lower GPA during followup than their continuously highly active peers(mean difference = -0.301, 95%CI: -0.543 to -0.058, p = 0.009) and all other adolescents(mean difference = -0.247, 95%CI: -0.475 to -0.019, p = 0.029). These differences were greater in girls than in boys.Conclusion: Lower levels of MVPA were associated with lower GPA in boys at baseline. Girls who were continuously inactive had lower GPA over the follow-up period than those who were continuously active. Finally, earlier pubertal development was associated with better academic achievement in girls.

Caution needed when interpreting muscle activity patterns during extremely low pedaling cadence

Dear editor,We noticed recent research that has just been published in Journal of Sport and Health Science(JSHS),comparing the muscular activity patterns in 1-and 2-legged cycling by Park and Caldwell.1 The authors reported that changes in muscle activities with 1-legged pedaling are due to a variety of changes in mechanical aspects of the pedaling motion,including altered crank torque patterns within the crank cycle,decreased pelvis stability,and the need for increased knee and ankle stiffness during the upstroke.The experiment was welldesigned and the discussion was fascinating.However,the testing protocol does not support the significance of the project,as stated in the first sentence of the abstract,“One-legged pedaling is of interest to elite cyclists and clinicians.”Their testing was conducted at 30 revolutions per min(rpm)and 30 watts(W),and both are too low for any kind of mechanical demand for cycling,either competitive sports or rehabilitation.The preferred cadences of experienced cyclists are approximately 85-95 rpm,whereas the most economic cadences are approximately 55-60 rpm.

Segmented sedentary time and physical activity patterns throughout the week from wrist-worn ActiGraph GT3X+ accelerometers among children 7-12 years old

Background:This study examined the volume and patterns of physical activity(PA) and sedentary time(ST) across different segments of the week among boys and girls.Methods:A total of 188 children aged 7-12 years wore a wrist-mounted ActiGraph GT3 X+accelerometer for 7 days.Time spent in PA and ST was calculated using ActiLife software.The mean number of minutes of light PA,moderate PA,vigorous PA,moderate-to-vigorous PA(MVPA),and ST were calculated per weekday(before school,during school,and after school) and per weekend day(morning and afternoon-evening).Results:After school represented the greatest accumulation of ST compared with before school and during school segments.Boys engaged in225.4 min/day of ST(95% confidence interval(CI):216-235),and girls engaged in 222.2 min/day of ST(95%CI:213-231).During school,boys engaged in significantly more MVPA than girls(46.1 min/day(95%CI:44-48) vs.40.7 min/day(95%CI:39-43)).Across the whole weekday,boys participated in significantly more MVPA than girls(103.9 min/day(95%CI:99-109) vs.95.7 min/day(95%CI:90-101)).The weekend afternoon—evening segment represented the larger accumulation of ST,where boys were significantly more sedentary than girls(367.5 min/day(95%CI:353-382) vs.339.8 min/day(95%CI:325-355),respectively).Conclusion:Our findings suggest that children are highly sedentary and spend little of their time in school in MVPA,especially girls.Routine breaks in school elicit increases in light PA and MVPA.Future work should consider the use of more active breaks within school time to encourage PA and reduce ST.
