Advantages – such as Q angle, lung size and bone density – are commonly thought to confer a performance advantage, there is no support in the literature that these factors confer any such advantage.@MaddieGroves_
Trans women athletes undergoing HRT increase their estradiol, affecting total body fat percentage, and also significantly reduces testosterone, reducing muscle mass, red blood cell count and other factors important for athletic performance.@MaddieGroves_ Image
@DrAdaCheungAU research is showing HRT lead to💪#muscle mass loss research shows ~7kg less than cis males), gain in fat mass, lower 🦴 bone density & drop in oxygen-carrying🩸red blood cells to F levels. Changes start within 3 mo & at 2 y is still continuing. @MaddieGroves_ Image

Many will look at a #transgender woman’s face and height (which doesn’t change with feminising hormones) and think ‘it’s unfair’. That is an assumption. A stereotype and not based on any science. Let’s go through what the science does show... 👩‍🔬
Note that being #trans is not a choice, and whilst complex, gender is influenced in part by innate factors such as genes 🧬. Only ~0.5% of people in the population are trans, and only 1/3 of those are #transwomen.
A #transwoman who has had puberty blockers as a teenager and never been through male puberty, has the physiology of a woman. 🙋What about trans women who transition later after puberty❓

#2 B-COMPLEX/MULTI VITAMIN. Buy a liposomal or other form that increases bio-availability. Take 1 capsule w/Breakfast and Lunch. If you have stomach upset, try sublingual (under tongue) EZ Melt B-Complex in AM & Multi w/iron for Dinner. amazon.com/Liposomal-Meth…
#3 OMEGA 3s. Fish Oil, Krill Oil, Algae Oil are all good sources of Omega 3. Be careful the EPA/DHA ratio. EPA helps with inflammation/DHA helps with cognition. You need both! Opt for a 1:1 or 2:1 ratio of DHA to EPA (2:1 ratio eg. 800 DHA/400EPA) amazon.com/3Care-Concentr…

I want to talk about the “7 Deadly Sins” ..

So much has been altered Throughout time that has basically kept everyone/MOST living in A state of fear of actually LIVING, divided & easily controlled .. Not to mention, so much contradiction was added.

Everyone makes mistakes,
Mistakes Can be learned from.
Sin is self reflection of the mind & soul, being able to forgive ones self is important for those who carry the weight of “sin”, but what it “sin” ?
The world has been separated by class, religion, race, Cree & so much more.

Think of this for an
Example;
Many poor Individuals see all these wealthy “stars”(some puppets doing all that they do/show the masses on purpose pushing them into agendas) living their extravagant life styles (by design) & want what they have. Many know they will never be able to achieve those riches

This systematic review and meta-analysis of RCTs comes to the conclusion that ~700 METs-min/week is the minimal dose to elicit clinically important changes in cognition in older adults.
- The estimated minimal exercise dose found that can elicit clinically relevant changes in cognition was 724 METs-min per week, with doses beyond the upper bound of WHO recommended level of physical activity providing less clear benefits.
- 724 METs-min per week is slightly above the lower bound of WHO recommended level of physical activity (i.e. 600 METs-min per week, equivalent to 150 min/week of moderate intensity or 75 min/week of vigorous activity).

This systematic review and meta-analysis aimed to investigate the efficacy of increasing dietary protein ingestion to improve lean body mass gain, skeletal muscle strength, and physical function in healthy subjects.
- Additional protein ingestion together with resistance training leads to small additional lean body mass and lower body strength.
- This effect seems to be more prominent in younger subjects ingesting ≥1.6 g/kg/day.

This study explored the effect of three different modes of resistance training on appetite hormones, cardiometabolic and anthropometric measures in males with obesity.
- 44 males with obesity were randomized to traditional resistance training (TRT, n = 11), circuit resistance training (CRT, n = 11), interval resistance training (IRT, n = 11) or control (C, n = 11) groups.
- All resistance training groups received 50 min of supervised training per session, three days per week, for 12 weeks.

This one found short-term, moderate-intensity downhill running to be an effective method of promoting gains in knee-extensor muscle strength, size and structure, with the former being explained mainly by neural changes and to a smaller extent by muscle hypertrophy.
- 4 weeks of moderate-intensity downhill running promoted neuromuscular adaptations in young, healthy adults.
- Neural adaptations appeared to contribute to most of the strength gains at 2 and 4 weeks, while muscle hypertrophy seemed to contribute to maximal voluntary torque changes from 2 to 4 weeks only.

Here, co-ingestion of cluster dextrin with meat protein hydrolysate did not augment postprandial amino acid availability or myofibrillar FSR as compared to co-ingestion of glucose during recovery from a whole-body resistance exercise despite increased intramuscular signaling.
- Cluster dextrin is a branched carbohydrate produced from waxy maize starch by the cyclization of a branching enzyme.
It has been shown to increase the rate of gastric emptying compared to glucose and standard dextrin due to a lower osmotic pressure.

Here's another one that suggests that the inherent biological risk for progression of microvascular complications may be largely independent of appropriate glycaemic control.
- This was a prospective observational study in 710 normoalbuminuric adolescents with type 1 diabetes from the non-intervention cohorts of the Adolescent Cardio-Renal Intervention Trial (AdDIT).
- In univariable Cox regression analysis, high albumin/creatinine ratio, higher HbA1c and higher diastolic blood pressure standard deviation scores were associated with greater risk of three-step diabetic retinopathy progression.

This is a retrospective analysis of the data from CALERIE, that tries to characterize the contributions of the loss of energy-expending tissues and metabolic adaptations to the reduction in resting metabolic rate following weight loss.
- CALERIE, or Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy, was a large-scale, randomized clinical trial in humans that involved a 25% reduction in energy intake over the course of a 2-year period.
Findings:

Here, the authors evaluated the effects of 16-week combined training program on brown adipose tissue activity, browning and autophagy markers, and serum pro-thermogenic/inflammatory inducers in patients with overweight and type 2 diabetes.
- Combined training increased glucose uptake in BAT and also in some white fat depots.
- Combined training also increased serum/molecular thermogenic/antiinflammatory markers and reduced the expression of autophagy genes in white adipocytes.

The objectives of this study were to examine whether weight loss, weight status, based on BMI categories, and abdominal obesity, as assessed by waist circumference, are associated with mortality risk in community-dwelling older adults during a 17-year follow-up.
- Self-reported weight loss was not associated with all-cause mortality after adjusting for health and lifestyle factors.
- However, men who self-reported weight loss of more than 3 kg had a 52% increased mortality risk compared to those who reported no weight loss.

This one found greater adiposity measures to be associated with CVD risk factors even after adjustments for covariates and physical fitness in Swedish 9-year-old children.
- Body composition and physical fitness were strongly associated.
- Fat mass and fat mass index were strongly and positively associated with CVD risk factors also after adjustments for covariates including physical fitness.

This systematic review and meta-analysis found that lifestyle modifications can be effective in the treatment of NAFLD with diet, exercise, or the combination of both being beneficial in its treatment.
- Exercise reduced weight compared to maintaining physical daily activities and education about a healthy lifestyle, HOMA-IR, oxygen consumption and intrahepatic lipids, assessed by H-MRS.
- The combination of diet and exercise reduced weight only compared to education about healthy lifestyle, HOMA-IR compared to the control group, intrahepatic lipids assessed by NAS score and liver enzymes.

This one found higher leisure-time physical activity levels to be associated with a lower risk of cardiovascular disease in Chinese retired adults, with the benefit threshold for CVD prevention equivalent to 3 to 5 times the world health organization (WHO) recommended minimum.
- The WHO recommends every adult to maintain a minimum of 150 min of moderate-intensity or 75 min of vigorous-intensity activity per week, which is equivalent to 7.5 weekly metabolic equivalent of task-hours ([MET]-hours/week) of physical activity.
- Compared with participants reporting LTPA less than the recommended minimum of 7.5 MET-hours/week, a lower risk was seen for those with 3 to 5 times the recommended minimum (22.5–37.5 MET-hours/week) with no additional benefit when exceeding 5 times the recommended minimum.

This one suggests that performing around 1800 MET-min/week (i.e. 64 min/day of moderate PA) is an effective method to prevent some major degenerative diseases that affect quality of life in a large part of the population over 50 years.
"American adults who perform at least 150 MET-min/week of PA presented reduced odds for sarcopenia, those who perform 150–1800 MET-min/week had reduced odds for osteoarthritis, and those who perform more than 1800 MET-min/week had reduced odds for osteoporosis...

This one suggests that low-grade systemic inflammation promotes proteasome activity through activation of the NF-κB signaling and reduces the insulin-dependent anabolic potential in the aged human skeletal muscle.
Main findings:

Older adults with plasma  hsCRP > 1 mg/L (defined as elevated systemic inflammation; ESI), but otherwise healthy demonstrate:
i) increased proteasome activity, accompanied by increased protein carbonylation and IKKα/β phosphorylation.

Given that early initiation of exercise after stroke is often advocated, the authors conducted this meta‐regression analysis with the primary objective of examining the association between time elapsed after stroke to initiation of exercise training and clinical outcomes.
- The number of adverse events in studies that were started within the first month after stroke was concerning, suggesting careful application of exercise training in the early phases.
- The time window for improved outcome in 6‐minute walk distance related to exercise training may span longer time periods than previously thought, and may fall within distinct post‐stroke phases, with no time association for other outcomes.

This systematic review and meta-analysis compares the effects of resistance training, whole body vibration training, and mixed training on muscle strength and physical performance in older people with sarcopenia.
- "Previous studies showed that RT can improve KES (knee extension strength), TUG (Timed Up and Go) times and GS (grip strength) in older people with sarcopenia, which is consistent with the result of our study...
"...However, CS (Chair Stand) times was not been significantly improved by RT in our study. We speculated that different RT protocols of included RT studies may be a reason why RT has no significant effect on CS in our study...

In this one, dietary intake of ALA and total omega-3 PUFA were associated with muscle strength and function in older women aged 65–72 years living in Finland.
- Both omega-3 PUFA and ALA were positively and significantly associated with short physical performance battery score, one leg stance, walking speed, and with lower inability to squat to ground.
- ALA intake was positively associated with knee extension force and inversely associated with fat mass.

1/ Παρασκευή με #fosstotounel, και ξεκινάμε #thread με την ανάλυση της υπόθεσης της #Ολυμπίας Κυρήκου, της οποίας χάθηκαν τα ίχνη το Σάββατο, 11 Νοεμβρίου 1995, απο την Νέα Ιωνία. Θα αναλύσουμε μία σειρά από 7 βίντεο της εκπομπής από το 1996 με πρώτο το bit.ly/3qyCrCn
2/ H εκπομπή γίνεται στις 2 Φεβρουαρίου, 1996, με τους συγγενείς να απευθύνονται στην νεαρή τότε Αγγέλω, για να τους βοηθήσει στην αναζήτηση. Να θυμίσουμε ότι το #fosstotounel ξεκίνησε κάπου μέσα στο 1995, οπότε βλέπουμε τα πρώτα βήματα της εκπομπής και των συντελεστών..
3/ Αυτο φαίνεται τόσο από την παραγωγή/ σετ και την εικόνα που έχουμε από τότε, όσο και από το γεγονός ότι πολλά από τα τηλεφωνήματα που γίνονταν από `τηλεθεατές` δεν μπορούσαν να διασταυρωθούν (όπως θα δούμε) με συνέπεια να παραπλανούν, πιθανότατα με δόλο, τις προσπάθειες
