The effects of target distance on kinematic sequence of the short game in male collegiate golfers.

Golf is an international sport that has become increasingly more popular in recent times. Previous literature has shown that golf approach shots are crucial to the success of elite golfers. However, there is no known publication investigating distances less than 100 yards, known as the short game.

Relationship between backpack load location, sex, anthropometric and body composition factors with postural sway in healthy young adults.

Objective: Evaluate the effect of backpack load location on postural sway and correlate sway path length (PL) to anthropometrics and body composition.

Methods: Fifteen participants aged 18-25 stood on a force plate with backpack load located high (LH), low (LL) or without backpack (NL). Body composition and anthropometric variables were correlated to PL.

The effect of posture on neck proprioception and head/neck stabilization in asymptomatic participants.

Objective: We sought to determine the effect of different body postures on neck proprioception and head/neck stabilization.

Methods: Twelve healthy college students completed a head repositioning task and a 'head still' task while wearing a headpiece (helmet) with laser fixed on top during standing, kneeling, sitting, and sitting with stabilization. Video data of the laser dot coordinates on a projection screen were obtained to examine the accuracy of the two tasks.

Temporal more than spatial regulation of sway is important for posture in response to an ultra-compliant surface.

Background And Aim: Many people use balance training as a rehabilitation or habilitation modality. Although the time course of changes to temporal and spatial aspects of postural sway over the initial weeks of such training is as yet unclear. Particularly, we sought to explore the effects of training on sway during a dynamic task of stance on an ultra-compliant surface.

Effects of plyometrics performed during warm-up on 20 and 40 m sprint performance.

Background: Postactivation potentiation in the form of a plyometric during warm-ups have been shown to improve performance in some speed/power events. This study aimed to determine if a plyometric during warm up can increase sprint performance in a 20 and 40 m sprint.

Methods: In this study we measured sprint times of 10 male track and field athletes over distances of 20 and 40 m after warm-ups with and without a plyometric exercise.

The acute effects of static stretching on the sprint performance of collegiate men in the 60- and 100-m dash after a dynamic warm-up.

Previous research has shown that static stretching has an inhibitory effect on sprinting performances up to 50 m. The purpose of this study was to see what would happen to these effects at longer distances such as those seen in competition. This study used a within-subjects design to investigate the effects of passive static stretching vs.

Gender bias on the effects of instruction on kinematic and kinetic jump parameters of high-level athletes.

The purposes of this study were to examine gender differences during drop jumps, to evaluate the effect of a set of simple instructions on kinematic and kinetic parameters during a drop jump, and to determine if there are gender differences in the effects of instruction on those parameters. Twenty-five basketball players, 13 men and 12 women, performed drop jumps from a box (height 30.5 cm) after being asked to perform a land and jump movement as they normally would do when aiming at maximum jump height.

Gender bias in jumping kinetics in National Collegiate Athletic Association Division I basketball players.

The purposes of this study are to examine gender differences in the contribution of the arm swing to jump height in men and women basketball players and to examine the role of upper-body strength in the contribution of arm swing to jump height. National Collegiate Athletic Association Division I basketball players (men n = 13, women n = 12) performed 4 jumping movements: squat jumps with hands on hips (SNA) and with arm swings (SA) and countermovement jumps with hands on hips and with arm swings (CMA). Differences were found between the jump heights of men and women.

Gender bias in the effects of arms and countermovement on jumping performance.

The ability to jump high is considered important in a number of sports. It is commonly accepted that the use of the arms and a counter movement increase jump height. In some sport situations (e.

The validation of a portable force plate for measuring force-time data during jumping and landing tasks.

The purpose of this study was to determine the reliability and validity of a portable force plate when analyzing jumping and landing tasks. Subjects performed 3 drop vertical jumps and 3 drop landings on both a standard strain gauge laboratory force plate and a portable force plate. In contrast to typical laboratory installed force plates, the portable 6-component force plate can be easily transported and used onsite at various training or data collection sites and incorporates Hall effect technology.
