| Abstract | The purpose of this investigation was to examine the acute hormonal response to the kettlebell swing exercise. Ten recreationally resistance trained men (age, 24 ± 4 years; height, 175 ± 6 cm; body mass, 78.7 ± 9.9 kg) performed 12 rounds of 30 seconds of 16 kg kettlebell swings alternated with 30 seconds of rest. Blood samples were collected before (PRE), immediately after (IP), and 15 (P15) and 30 minutes after exercise (P30) and analyzed for testosterone (T), immunoreactive growth hormone, cortisol (C), and lactate concentrations. Heart rate and rating of perceived exertion were measured at the end of each round. Testosterone was significantly higher (p ≤ 0.05) at IP than at PRE, P15, or P30 (PRE: 28 ± 3; IP: 32 ± 4; P15: 29 ± 3; P30: 27 ± 3 nmol·L). Growth hormone was higher at IP, P15, and P30 than at PRE (PRE: 0.1 ± 0.1; IP: 1.8 ± 1.2; P15: 2.1 ± 1.1; P30: 1.6 ± 1.3 µg·L). Cortisol was higher at IP and P15 than at PRE and P30 (PRE: 617 ± 266; IP: 894 ± 354; P15: 875 ± 243; P30: 645 ± 285 nmol·L). Lactate was higher at IP, P15, and P30 than at PRE (PRE: 1.1 ± 0.5; IP: 7.0 ± 3.0; P15: 4.0 ± 2.7; P30: 2.5 ± 1.8 mmol·L). Heart rate increased progressively from 57 ± 12 at PRE to 170 ± 10 at IP. The exercise protocol produced an acute increase in hormones involved in muscle adaptations. Thus, the kettlebell swing exercise might provide a good supplement to resistance training programs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
