Whether you should use a sweeping swing or take a divot as a senior golfer really depends upon the club you are using.
If you are playing the shot with an iron then this club suits a swing that would see you taking a divot. However, if you are playing the shot with a driver or fairway wood, then this shot would require a more sweeping swing for you to play it effectively.
If we look at the club head on an iron, you will notice the angle of the club face, or the loft. It is the loft that propels the golf ball into the air and the amount of loft the club has dictates how high the shot will be hit. In order for the club head to work correctly, the loft of the club face needs to be presented correctly to the golf ball. In order to do this, the club head must move back to the ball and strike the lower right hand side of the golf ball. This action then forces the golf ball up the club face and into the air, so to achieve this, an iron requires a downward strike towards the ball to connect with the lower right hand side of the ball and this would see you taking a divot following connection with the ball.
Woods, however, have much less loft on them and require a more sweeping action to encourage the connection between the club face and golf ball to be slightly on the upswing to help propel the ball into the air.
The club head sweeps towards the golf ball just skimming the ground and no divot is taken with this swing.
To encourage the two different swings, slightly adjust your set up depending upon the club that you are using. Initially, if you are playing an iron, the ball will be further back in your stance than if you were playing a wood, as the position that the ball is in within your stance influences whether you will hit down at the ball or sweep in and catch the ball slightly on the upswing. The correct ball position is centre of the feet for your wedges and 9 iron, and then moving half a ball to the left for each subsequent club until you get to your driver which is played from the inside of your left big toe. The bottom of your swing arc will tend to be just left of centre of your feet so this is where the club head will be at its lowest point and striking down. Once this point is reached, the club head will begin to rise so placing the ball correctly within your stance will encourage the correct swing action.
Weight position also influences whether you make a sweeping action or take a divot as you swing. When you play your irons, you want to set up with slightly more weight on your left side (for right handed golfers) and when playing your woods, set up more evenly with your weight or be slightly on your right side. Placing more weight on your left side will encourage you to make a steeper swing with the golf club and this will see you hitting down more steeply towards the ball. More weight on your right side encourages you to make a flatter swing and to keep the club head lower to the ground, which in turn allows you to return the club head back to the ball at a much gentler angle and sweep through the strike.
Finally, you want to use your wrists more when playing an iron shot as using your wrists generates a more upward movement in the club head. This will create more height in the club head as you swing away from the ball and allow you to attack back down with the club head on a steeper angle, encouraging a downward strike and you taking a divot.
Use your wrist less when playing a shot with your woods and the club head will move around you on a much lower, gentler swing arc and encourage you to sweep the club head over the turf as you strike the ball.
