Akungabazeki ngakho: I-BodyPUMP iyinto eshisa kakhulu ukushaya amakilabhu ezempilo kusukela ku-Spinning. Angeniswe esuka eNew Zealand eminyakeni emithathu nje edlule, la makilasi okuqeqesha isisindo manje anikezwa kumakilabhu okuqina angaphezu kuka-800 ezweni lonke. Kepha abanye ochwepheshe bayangabaza ukuthi ngabe lolu hlelo, olubandakanya ukuphindaphinda inqwaba ngezisindo ezilula, luyavumelana nezicelo zalo.

I-Web site yalolu hlelo yenza isitatimende esinesibindi: "I-BodyPUMP izothuthukisa ikhono lakho lokushisa amafutha futhi isize ekwakheni imisipha namandla. Ngokumane nje, kuyindlela esheshayo endaweni yonke yokuthola isimo." Ingabe kunjalo? Ukuze uthole lokhu, uShape ujube abacwaningi baseCalifornia State University, eNorthridge, ukuthi balandelele amadoda nabesifazane ekilasini le-BodyPUMP. Yize isifundo sinamaphutha aso, njengosayizi omncane wesampula, imiphumela ibingathandeki. Ngemuva kwamasonto ayisishiyagalombili, izifundo azibonisanga ukuzuza okukhulu kwamandla noma ukulahleka kwamafutha omzimba. Okuwukuphela kwenzuzo elinganisekayo kwakuyinzuzo ekukhuthazeleni imisipha.

Abagqugquzeli beBodyPUMP nososayensi bakholelwa ekutheni isifundo besimfishane kakhulu ukuthi bangahlola ngokwanele uhlelo. "Ukube [lolu cwaningo] belulandela lezi zifundo isikhathi eside bebengabona izinguquko ezinkulu," kusho uTerry Browning, iphini likamongameli we-The STEP Company, umhambisi wase-U.S. WeBodyPUMP. Abacwaningi bagcina ukuthi amasonto ayisishiyagalombili akwanele ukuhlola isimangalo sokuthi "kuyindlela eshesha kunazo zonke endaweni yonke yokuba sesimweni."

Ochwepheshe bangaphandle ababuyekeze lolu cwaningo bathi amasonto ayisishiyagalombili athathwa njengobude obuncane obamukelekayo bezifundo zalolu hlobo. "Bekungaba kuhle ukube isifundo siqhubeke isikhathi eside," kusho isazi sokuzivocavoca umzimba uDaniel Kosich, Ph.D., umeluleki wezempilo e-Aurora Cardiology Practice eDenver."Kodwa kunezifundo zamasonto ayisishiyagalombili ezikhombise ushintsho olukhulu kakhulu emandleni." (Bheka "Okutholakele Okusindayo.")

Umzamo omkhulu, imbuyiselo enesizotha

Izihloko zocwaningo lwe-CSUN zithathe ikilasi le-BodyPUMP lehora elide kabili ngesonto futhi zagwema okunye ukuqeqeshwa kwesisindo. "Sacela ababambiqhaza ukuthi baqhubeke nemikhuba yabo ejwayelekile yokuzivocavoca umzimba kanye nemikhuba yokudla," kusho u-Eve Fleck, M.S., umbhali ophambili ocwaningweni, owenza ucwaningo ngomqondo wenkosi yakhe. Ngaphambi kokuthi uhlelo luqale nangemva kwesonto lesishiyagalombili, abacwaningi balinganise amandla ezifundo emshinini wokuhlwaya ebhentshini besebenzisa isivivinyo esisodwa (isisindo esikhulu izihloko ezingasiphakamisa kanye) nokukhuthazela kwemisipha (kangaki lapho bebhentshi bengacindezela inani yesisindo esinqunyelwe ukuhlolwa kokukhuthazela kwe-YMCA: amakhilogremu angama-35 kwabesifazane, amakhilogremu angama-80 kwabesilisa).

Ngenkathi izihloko ezingama-27 ziqala lolu hlelo, kwaqedelwa i-16 kuphela, inhlanganisela yama-novice nabaphakanyisi abanolwazi. (Abaningana bashiya phansi ngenxa yezingxabano zesikhathi, eyodwa ngoba lolu hlelo lwenza isifo samathambo saba namandla.) Ngemuva kwamasonto ayisishiyagalombili, okuwukuphela koshintsho olulinganisekayo kwaba ukwanda kwenani lezinto eziphindaphindwayo ezaziphindaphindwa ebhentshini. "Isilinganiso sokwenyuka besibalulekile, cishe ngamaphesenti angama-48," kusho uFleck. Futhi, abathathu kwabaqalayo abane bathole amandla, isilinganiso samaphesenti angu-13.

UFleck uchaza ukuthi ukukhuthazela namandla kuyakhuphuka ngokwengxenye ekuthuthukiseni ukuhlangana kwe-neural okuvamise ukutholwa ngabaphakamisi be-novice. Uthi akummangazanga ukuthi leli qembu ngokwesilinganiso alizange liwathole amandla, ngoba kuba nzima kubadlali abanolwazi lokuliphakamisa. Ukuze uthole amandla, i-American College of Sports Medicine incoma ukuthi uphakamise amaphesenti angama-70-80 omkhawulo wakho wokuphindaphinda okukodwa. Kepha ekilasini elijwayelekile le-BodyPUMP, izifundo ziphakamise isilinganiso samaphesenti ayi-19 kuphela wobukhulu bazo.

Abagqugquzeli beBodyPUMP bavikela ukusetshenziswa kwezisindo ezilula. "Isizathu sesisindo esincane ukuthi lolu hlelo lwenzelwe ukuthuthukisa ukukhuthazela kwemisipha," kusho uBrowning. (Ukukhuthazela kwemisipha, ochwepheshe bayavuma, kubalulekile emisebenzini ethatha amahora amaningi, njengokuhamba ngebhayisikili, ukuhamba izintaba nokushushuluza eqhweni.) UBrowning uthi ukukhushulwa kwamandla weWebhusayithi kusebenza kuphela kubaqalayo bokuzivocavoca, kepha lesi sitatimende senkinga asiveli kusayithi. UFleck uthi uzodinga izihloko eziningi ze-novice ukuthola ukuthi ngabe abaphakamisi bokuqala baqala yini ukuthola amandla nge-BodyPUMP. Umkhawulo obalulekile wocwaningo, ochwepheshe bayavuma, ukuthi ulwazi lokuqeqeshwa kwesisindo lwezifundo lwaluhluke kakhulu. "Njengosayizi wesampula omncane kangaka ohlukaniswe amazinga ahlukene wokuqina, kunzima ukuthola amandla ezibalo," kusho uKosich.

Ingozi yokulimala?

Abagqugquzeli be-BodyPUMP balondoloza ukuthi ukukhuthazela kwemisipha kutholakala kangcono ngokwenza ukuphindaphinda inqwaba yokuzivocavoca ngakunye. Kodwa-ke, ucwaningo lubonisa ukuthi ukwenza iziphindaphinda eziyisishiyagalombili kuya kweziyi-12 zendabuko kuthuthukisa ukukhuthazela kwemisipha, kanti futhi kwakha amandla, amathambo kanye nemisipha eyanele ukuze kuthuthukiswe umzimba. "Uma uthola amandla [emisipha] uzitholela [imisipha] ngokuzenzakalela, kodwa ngokusobala okuphambene nalokhu akulona iqiniso," kusho uWayne Westcott, Ph.D., umqondisi ocwaninga ngemfanelo eSouth Shore YMCA yaseBoston.

Ukuphindaphinda inqwaba akudingekile kuphela, kusho u-Westcott, kodwa kungase kwandise ingozi yokulimala ngokweqile. Azikho izifundo ze-CSUN ezibike ukulimala okusha. "Kodwa [ukulimala] okunjalo kungathatha isikhathi esingaphezu kwamasonto ayisishiyagalombili ukuba kuvele," kusho uWilliam C. Whiting, Ph.D., umqondisi welabhoratri ye-biomechanics e-CSUN nomunye wabeluleki bakaFleck.

Abacwaningi futhi babekhathazekile ngokuthi ukuphindaphinda okuningi (kufika ku-100 kwezinye izivivinyo) kungase kukhuthaze inqubo yobudlabha. UFleck uthe ujwayele ukubona isimo esingesihle, ikakhulukazi kwabasanda kufika. Babevame ukulayisha ibha ngesisindo esiningi kakhulu, futhi ngokuphindaphinda kwe-40 yayingakwazi ukuyiphakamisa. Uqaphele ukuthi abafundisi ababambe iqhaza esifundweni sakhe akuvamile ukuthi balungise ababambiqhaza ababephakamisa ngokungafanele. "Ngisho nangemva kwamasonto ayisishiyagalombili, zonke izifundo zethu bezisebenzisa isihlakala esingesihle, umhlane, indololwane, ihlombe namadolo," kusho uFleck. UBrowning uveza ukuthi abafundisi beBodyPUMP banikela ngemihlangano yokucobelelana ngolwazi yemizuzu eyi-15 ngaphambi kwekilasi nokuthi abafikayo bayanxuswa ukuthi baye okungenani eyodwa ngaphambi kokufunda.

Ngokusobala, amakilasi e-BodyPUMP amnandi kakhulu. Abahlanganyeli babika ukuthi bathanda ukuphakamisela izinsimbi emculweni futhi bathole uhlelo lukhuthaza. Kodwa ingabe amakilasi kufanele athathwe? "Kumuntu osemusha, kuyindlela yokuqalisa ukuqeqeshelwa isisindo," kusho uFleck, eqaphela ukuthi izifundo eziningi bezisatshiswa kakhulu ukuphakamisa izinsimbi zize zizame iBodyPUMP. Kepha uphakamisa ukuthi uma wenza i-BodyPUMP, yiba nabafundisi abakhombisa inqubo yokuvivinya umzimba ngakunye ngaphandle kwekilasi futhi wehlise inani lezimpinda ozenzayo ukunciphisa ingozi yokulimala.

Uma ubheke ukwakha izicubu zomzimba, wandise umzimba wakho futhi uqinise amathambo akho, uFleck uthi, namathela ohlelweni oluvamile lokuqeqesha isisindo. Ngaleso sikhathi, i-BodyPUMP ingase ikusize ugcine amandla emisipha, futhi, uyanezela, "Kuyinto ejabulisayo ukuphonsa esimisweni sakho kanye ngesikhathi."
