6. Stretching Prevents Injuries
The guy lifting beside you looks like he should write the book on muscle. Talks like it, too. He's worked out since the seventh grade, he played D-1 football, and he's big.
But that doesn't mean he knows what he's talking about. Starting now, ignore him.
The gym is infested with bad information. Lies that start with well-intentioned gym teachers trickle down to students who become coaches, trainers, or know-it-all gym-rat preachers. Lies morph into myths that endure because we don't ask questions, for fear of looking stupid.
Scientists, on the other hand, gladly look stupid—that's why they're so darn smart. Plus, they have cool human-performance laboratories where they can prove or disprove theories and myths.
Here's what top exercise scientists and expert trainers have to say about the crap that's passed around in gyms. Listen up and learn. Then go ahead, question it.
Lifting super slowly produces superlong workouts—and that's it. University of Alabama researchers recently studied two groups of lifters doing a 29-minute workout. One group performed exercises using a 5-second up phase and a 10-second down phase, the other a more traditional approach of 1 second up and 1 second down. The faster group burned 71 percent more calories and lifted 250 percent more weight than the superslow lifters.
The real expert says: "The best increases in strength are achieved by doing the up phase as rapidly as possible," says Gary Hunter, Ph.D., C.S.C.S., the lead study author. "Lower the weight more slowly and under control." There's greater potential for growth during the lowering phase, and when you lower with control, there's less chance of injury.
To a point, sure. But put down the shake for a sec. Protein promotes the muscle-building process, called protein synthesis, "but you don't need exorbitant amounts to do this," says John Ivy, Ph.D., coauthor of Nutrient Timing.
If you're working out hard, consuming more than 0.9 to 1.25 grams of protein per pound of body weight is a waste. Excess protein breaks down into amino acids and nitrogen, which are either excreted or converted into carbohydrates and stored.
The real expert says: More important is when you consume protein, and that you have the right balance of carbohydrates with it. Have a postworkout shake of three parts carbohydrates and one part protein.
Eat a meal several hours later, and then reverse that ratio in your snack after another few hours, says Ivy. "This will keep protein synthesis going by maintaining high amino acid concentrations in the blood."
Before you skip that workout, determine how sore you really are. "If your muscle is sore to the touch or the soreness limits your range of motion, it's best that you give the muscle at least another day of rest," says Alan Mikesky, Ph.D., director of the human performance and biomechanics laboratory at Indiana University-Purdue University at Indianapolis.
In less severe instances, an "active rest" involving light aerobic activity and stretching, and even light lifting, can help alleviate some of the soreness. "Light activity stimulates bloodflow through the muscles, which removes waste products to help in the repair process," says David Docherty, Ph.D., a professor of exercise science at the University of Victoria in Canada.
The real expert says: If you're not sore to the touch and you have your full range of motion, go to the gym. Start with 10 minutes of cycling, then exercise the achy muscle by performing no more than three sets of 10 to 15 repetitions using a weight that's no heavier than 30 percent of your one-rep maximum, says Docherty.
Maybe if you're a figure skater. Researchers at the Centers for Disease Control and Prevention reviewed more than 350 studies and articles examining the relationship between stretching and injuries and concluded that stretching during a warmup has little effect on injury prevention.
"Stretching increases flexibility, but most injuries occur within the normal range of motion," says Julie Gilchrist, M.D., one of the study's researchers. "Stretching and warming up have just gone together for decades. It's simply what's done, and it hasn't been approached through rigorous science."
The real expert says: Warming up is what prevents injury, by slowly increasing your bloodflow and giving your muscles a chance to prepare for the upcoming activity. To this end, Dr. Gilchrist suggests a thorough warmup, as well as conditioning for your particular sport.
Of course, flexibility is a good thing. If you need to increase yours so it's in the normal range (touching your toes without bending your knees, for instance), do your stretching when your muscles are already warm.
Don't abandon your trusty bench for exercises like the chest press and shoulder press if your goal is strength and size. "The reason people are using the ball and getting gains is because they're weak as kittens to begin with," says Craig Ballantyne, C.S.C.S. You have to reduce the weight in order to press on a Swiss ball, and this means you get less out of the exercise, he says.
The real expert says: A Swiss ball is great for variety, but center your chest and shoulder routines on exercises that are performed on a stable surface, Ballantyne says. Then use the ball to work your abs.

Sometimes machines can build muscle better—for instance, when you need to isolate specific muscles after an injury, or when you're too inexperienced to perform a free-weight exercise.
If you can't complete a pullup, you won't build your back muscles. So do lat pulldowns to develop strength in this range of motion, says Greg Haff, Ph.D., director of the strength research laboratory at Midwestern State University in Wichita Falls, Texas.
The real expert says: "Initially, novice athletes will see benefits with either machines or free weights, but as you become more trained, free weights should make up the major portion of your training program," says Haff.
Free-weight exercises mimic athletic moves and generally activate more muscle mass. If you're a seasoned lifter, free weights are your best tools to build strength or burn fat.

Excessive hairiness in women is not just a cosmetic problem but is likely to be a sign of an underlying medical condition, say UK doctors in a report.
Five to 15% of women have excess hair, and a hormone disorder is the most likely cause in many cases, they said.
Women with the problem should not be afraid to seek medical advice, the Royal College of Obstetricians and Gynaecologists report urged.
Polycystic ovary syndrome (PCOS) is the cause in 70% to 80% of cases.
Report author, Dr Rebecca Swingler, a specialist registrar in obstetrics and gynaecology at St Michael's Hospital in Bristol, said the condition, known as hirsutism, is distressing and can be particularly upsetting for young women.
Estimates of how many women are affected are likely to be underestimated because women can be reluctant to seek help, she added.
In addition to PCOS, which is a major cause of fertility problems, rarer causes of excessive hairiness include certain tumours and thyroid dysfunction, as well as the use of certain drugs.
Mild cases can be treated cosmetically, she said, but in moderate to severe cases, hormone therapy, such as the oral contraceptive pill and other treatments are available.
Weight loss, especially in obese women, may also help reduce high levels of the male hormone testosterone which can be an underlying factor in cases of excess hair.
"Often women have spent many years trying to cope with their hirsutism before they seek professional help," said Dr Swingler.
"Women need to look at themselves in the context of their family and ethnicity and what is 'normal' for them.
"If they notice a change in the pattern of hair growth or they notice they having to wax more often then they should seek help," she said.
Reluctance
Professor Stephen Franks, an expert in reproductive endocrinology at Imperial College London, said the condition could be very embarrassing and women might be reluctant to seek medical advice.
They may also not realise hirsutism could be linked to a condition like PCOS because symptoms such as irregular periods are not present, he added.
"It's always worth getting it investigated. Even if it's a benign condition."
Professor Franks said how much hair growth was considered excessive was subjective, but that women should not be afraid to seek help.
Rachel Hawkes, chairwoman of PCOS charity Verity, said many women with excess hair growth did not actively seek treatment because they were embarrassed.
"The effect that excess hair can have on a woman's self-esteem and how she views herself as a woman - and therefore her quality of life - can be extremely distressing.
"We recommend women with PCOS who suffer with excess hair growth seek the advice of their GP, or ask to be referred to an endocrinologist or dermatologist."

JAKARTA -- Sunat atau proses pemotongan pada kulit luar ujung (kepala) penis dapat mengurangi risiko terinfeksi HIV (human immunodeficiency virus) karena bagian kulit ujung penis yang lembab dan basah dapat menjadi tempat yang ideal bagi virus HIV hidup."Negara Asia dan Afrika dengan prevalensi populasi laki-laki disunat kurang dari 20 persen mempunyai prevalensi HIV beberapa kalu lebih tinggi dibandingkan dengan negara-negara yang populasi laki-laki disunat mencapai lebih dari 80 persen," kata Direktur Pelayanan Kesehatan Yayasan Kusuma Buana dr Adi Sasongko dalam diskusi tentang kesehatan yang berlangsung di Jakarta, Selasa.
Jakarta, Kompas -
Menurut Sekretaris Jenderal Departemen Kesehatan Sjafi’i Ahmad dalam seminar bertema ”Memahami Dahsyatnya Kerusakan Otak Anak akibat Kecanduan Pornografi dan Narkoba”, Senin (2/3) di Jakarta, pornografi memicu kekerasan seksual dan menurunkan mutu sumber daya manusia.
Otak merupakan pusat pengaturan perilaku, terdiri dari banyak sirkuit, melibatkan beberapa area yang terbentuk dari proses belajar. ”Anak dan remaja yang kecanduan pornografi akan mengalami gangguan perilaku dan kemampuan inteligensia, merasa senang bila melihat materi pornografi,” kata Ketua Divisi Neurologi Anak Fakultas Kedokteran Universitas Indonesia- Rumah Sakit Cipto Mangunkusumo Yetty Ramli.
Ahli bedah saraf Rumah Sakit San Antonio, AS, Donald L Hilton Jr, menjelaskan, kecanduan mengakibatkan otak bagian tengah depan (
Kecanduan pornografi sama prosesnya dengan kokain dan zat adiktif lain. Paparan pornografi menyebabkan perubahan konstan pada neurotransmiter dan melemahkan fungsi kontrol. Seseorang yang kecanduan pornografi tak bisa mengontrol perilaku seksnya dan mengalami gangguan memori.
”Kondisi ini tidak terjadi segera, tetapi melalui tahapan dan ditandai tindakan impulsif kecanduan dan perubahan perilaku,” ujarnya. Kerusakan otak akibat kecanduan ini lebih berat dibandingkan dengan jenis kecanduan lain.
Kepala Pusat Pemeliharaan, Peningkatan, dan Penanggulangan Inteligensia Kesehatan Departemen Kesehatan Jofizal Jannis menambahkan, kecanduan pornografi dan narkoba mengakibatkan kegagalan adaptasi sosial. Kecanduan tersebut juga merusak fungsi otak dan struktur otak dengan pola yang sama dengan gejala-gejala adiksi fisiologis karena obat-obatan dan alkohol.
”Tidak seperti adiksi lainnya, kecanduan pornografi tidak hanya memengaruhi fungsi luhur otak, tetapi juga merangsang tubuh, fisik, dan emosi diikuti perilaku seksual,” kata Jofizal.
Bila gangguan perilaku dan kemampuan inteligensia itu meluas, hal itu akan memperburuk kemampuan, kesehatan fisik, mental, dan sosial.
Hilton menyatakan, pencandu butuh menjalani terapi. Metodenya adalah memotivasi pencandu sehingga mau berupaya terbebas dari kecanduan, menciptakan situasi aman dengan menghambat akses pada pornografi, membentuk grup konselor sebaya, memperkuat spiritualitas.
Ketua Pelaksana Yayasan Kita dan Buah Hati Elly Risman mengimbau agar para orangtua mewaspadai materi pornografi di berbagai media, di antaranya komik, situs porno,
”Pemerintah hendaknya memblokir situs-situs internet yang memuat materi pornografi. Ada beberapa situs pornografi yang menggunakan nama tokoh kartun atau nama binatang yang bisa tanpa sengaja dibuka anak-anak saat mengerjakan tugas sekolah,” kata Elly menegaskan.
