“…This could increase the emphasis on the lower trapezius and rhomboid groups at the cost of LD activity. The results of this study agree with those reported by Wills et al (19), which indicated that a wide grip, whether anterior or posterior, elicited a greater level of electrical activity in the LD than a CG. Those researchers also indicated that a wide anterior grip produced greater activity in the lateral portion of the LD than a wide posterior grip.…”

“…Articles in professional journals and fitness periodicals have argued the superiority of various handgrip positions for targeting the LD during the lat pull-down exercise (1,5,12,(19)(20)(21). We used 4 of the most commonly used handgrip positions to examine which handgrip elicited the highest level of electrical activity in the LD and 4 other accessory muscles.…”

“…These variations normally involve changes in hand position and range of motion (ROM) (1,5,12,(19)(20)(21). Many articles in both professional journals and the popular literature have offered differing opinions concerning the best hand and bar positions for targeting the LD during the performance of the lat pull-down exercise (1,5,12,(19)(20)(21). The differences in opinion among fitness professionals were further illustrated by an on-line poll held by the National Strength and Conditioning Association.…”

“…When asked whether the front or back lat pull-down was superior at developing the LD, 150 members favored the back pull-down position, whereas 903 members voted for the front pull-down. Few controlled studies that have examined the lat pull-down exist (19), and no study has examined the effect of hand position on specific muscle recruitment patterns during the performance of the exercise. Therefore, the purpose of this study was to investigate the effects of 4 commonly used hand positions on the activity of selected shoulder muscles during the performance of the lat pulldown exercise.…”

This study aimed at investigating the effects of different hand positions on the electromyographic (EMG) activity of shoulder muscles during the performance of the lat pulldown exercise. Ten healthy men performed 3 repetitions of the lat pull-down exercise using their experimentally determined 10RM (repetition maximum) weight. Four different common variations of the lat pull-down were used: close grip (CG), supinated grip (SG), wide grip anterior (WGA), and wide grip posterior (WGP). Normalized root mean square of the EMG (NrmsEMG) activity for the right posterior deltoid (PD), latissimus dorsi (LD), pectoralis major (PM), teres major (TM), and long head of the triceps (TLH) were recorded using surface electrodes and normalized using maximum voluntary contractions. Repeated measures analysis of variance for each muscle detected statistical differences (p Ͻ 0.05) in myoelectric activity among hand positions during both the concentric and eccentric phases of the exercise. During the concentric phase, NrmsEMG results for the LD included WGA Ͼ WGP, SG, CG. For the TLH: WGA Ͼ WGP, SG, CG and WGP Ͼ CG, SG. For the PD: CG, WGA, SG Ͼ WGP. For the PM: CG, WGA, SG Ͼ WGP. During the eccentric phase, the LD produced the following patterns: WGA Ͼ WGP, SG, CG and WGP Ͼ CG. The TLH pattern showed WGA Ͼ SG and CG. For the PD: CG Ͼ WGA, WGP. The results indicate that changes in handgrip position affect the activities of specific muscles during the lat pull-down movement. Also, performance of the lat pulldown exercise using the WGA hand position produces greater muscle activity in the LD than any other hand position during both the concentric or eccentric phases of the movement.

Grip Width and Forearm Orientation Effects on Muscle Activity During the Lat Pull-Down

Based on electromyographic (EMG) studies, an anterior (in front of the face) wide grip with a pronated forearm has been recommended as the optimal lat pull-down (LPD) variation for strengthening the latissimus dorsi (LD) (Signorile, JF, Zink, A, and Szwed, S. J Strength Cond Res 16: 539-546, 2002; Wills, R, Signorile, J, Perry, A, Tremblay, L, and Kwiatkowski, K. Med Sci Sports Exerc 26: S20, 1994). However, it is not clear whether this finding was because of grip width or forearm orientation. This study aimed to resolve this issue by comparing wide-pronated, wide-supinated, narrow-pronated, and narrow-supinated grips of an anterior LPD. Twelve healthy men performed the 4 grip variations using an experimentally determined load of 70% of 1 repetition maximum. Two trials of 5 repetitions were analyzed for each grip type. Participants maintained a cadence of 2-second concentric and 2-second eccentric phases. The grip widths were normalized for each individual by using a wide grip that corresponded to their carrying width and a narrow grip that matched their biacromial diameter. Surface EMG of the LD, middle trapezius (MT), and biceps brachii (BB) was recorded, and the root mean square of the EMG was normalized, using a maximum isometric voluntary contraction. Repeated-measures analysis of variance for each muscle revealed that a pronated grip elicited greater LD activity than a supinated grip (p < 0.05), but had no influence of grip type on the MT and BB muscles. Based on these findings, an anterior LPD with pronated grip is recommended for maximally activating the LD, irrespective of the grip width (carrying width or biacromial diameter).
