Kakak nyamar jadi turis cungkok dulu yaak nyama nyamain diri biar punya group 🤗, sekalian dapat ilmunya ikutan mutar mutar show pengetahuan about Buddha 😂. Yang jadi foto grafer kakak orang cungkok juga kali ini..cuma kakak bilang xie..xie..already help taken picture to me sok paten kakak 😅 . Lihat sekitarmu belajar apa yang bisa baik buat diri sendiri ..ga dimana aja KEPO kakak memang tinggi 🤗 #science #lookaround #teavel #trip #bangkok #thai #mygoldenyears #like4like #daybyday #neverend
Petroglyphs, Saudiarabien, Saudiarabia

The rock drawings (also known as petroglyphs) in the Hima region of south-western Saudi Arabia have been intriguing scientists from all over the world for decades. Yet, we still know very little about why and when these rock paintings in the desert were created. To this very day, archaeologists disagree on how old the illustrations are. An international team led by Professor Meinrat O. Andreae of the Max Planck Institute for Chemistry has now discovered a scientific method that can be used to date the rock paintings more accurately. You can read more about it in our latest press release. https://www.mpic.de/en/news/press-information/news/the-secret-of-the-rock-drawings.html #petroglyphs #saudiarabien #saudiarabia #felsbild #chemistry #chemie #maxplanck #mpichemie #mpichemistry #maxplanck #maxplanckgesellschaft #forschung #science #wissen #wissenschaft Photo: M.

Have a difficult time meeting your goals? Maybe it is because you actually do not have a goal. Most people do not have an underlying disease that inhibits them from losing fat, getting fit, healthy, adding muscle, and increasing cognition. Your issue is that you have no real goal, you are not intentional, and you do not like to hear that. You may be right, the status quo is unhealthy, inflamed, sedintary, over-fat, and has a diminishing IQ, and they all have one thing in common; no, it is not some disease, it is lack of a goal, and intentionality. People do well at what they are well intentioned toward; making money, finishing a degree, building a social media following, and moving up the ranks of this carnal world. Start admitting you have an unhealthy obsession with being unhealthy, and make a goal. Set a little goal. Meet it, and then another little goal. #fitness #physique #bodybuilding #weightlifting #keto #ketogenic #carnivore #strength #muscle #health #science #diet #nutrition #plantbased #vegan #paleo #lchf #lowcarb #highfat #motivation #gym #ketogenicdiet

For a long time, it was assumed that force production took place during a very short time period during the downswing (~0.2 s or less). For that reason, it was often recommended to prioritize exercises that were very rapid and utilized the fast-acting, elastic component of the stretch-shortening cycle.

But recent work has suggested that force production occurs in a much longer time window than previously thought (0.5-0.8 s). This would put a greater emphasis on the ability to produce large quantities of force, rather than just producing it as fast as possible.

For example, the table here is from Wells et al (2018). Link: https://www.ncbi.nlm.nih.gov/m/pubmed/29300147/

They assessed force production variables during various jump tasks and an Isometric mid-thigh pull (IMTP) and correlated it with clubhead velocity of skilled golfers.

Previously, it would have been expected that the strongest correlations would be rate of force development during the shorter time frames (RFD < 200 ms) and the Drop Jump (DJ), as these emphasize that fast-acting force production.

What they actually saw was a strong relationship with impulse (force x time) during the countermovement jump and squat jumps, which are a little slower but emphasize more concentric force than the depth jumps. RFD also was not significant until the later time points.

So what does this actually mean? Being able to produce force quickly is beneficial. But, it appears skilled golfers actually have more time to produce that force than we once thought. This is because the lower body starts producing force before the downswing starts. This gives the golfer more time to produce force and generate speed.

This helps explain why strength and concentric jump tasks are highly correlated with swing speed since they are slower, but produce a ton of force.

Based on this, how can we target swing speed?

1. Golf instructors could target the ability to increase upper-lower body separation to allow for a bigger window to produce force.

2. Physical training should target the ability to produce large amounts of force from the ground up in a relatively quick timeframe.
