Here are the tennis-specific notes and definitions to help you better understand the chart.

Throwing:
We all know that the service and overhead motion in tennis is identical to baseball and football. It is not surprising to note that when baseball players or quarterbacks take up tennis, they serve like Pete Sampras.

Catching:
It has long been understood that the soft hand skills required for volleying, as well as drop shots, lobs, and other touch shots in tennis are terrific catching skill-builders for other sports.

Striking:
Anyone who has played tennis knows how much easier tennis makes learning all other racquet sports. In fact, studies have proven significant carryovers from one racquet sport to others, as well as to other striking activities like baseball and hockey.

Running & Striking:
This very specific skill is one of the most challenging features of tennis, and one of the most valuable skill-builders and developing athlete can master. In this area, most other sports do not compare to all.

Movement Rhythm:
Sports educators are now broadly beginning to emphasize the importance of rhythm in ports, although dance teachers have long expounded it's benefits. Because tennis is a continuous rhythm activity, it offers many timing and rhythm benefits not available from many other sports. It may be interesting to compare football and tennis in this regard. In tennis, players are constantly involved with the ball; however in soccer, a center halfback, for example will only be in contact with the ball about two minutes in a full court 90-minute soccer game. Further the 3-step movement in sports, like kicking in football, is well-known. In tennis as well, leading coaches are pointing out that almost all baseline movement can be covered in three steps.

Aerobic:
Although tennis is accepted as more anaerobic than aerobic, the aerobic benefits of playing tennis are very high as compared to other sports such as baseball or golf.

Anaerobic:
There was a recent comparison of calories burned by different activities over a 3-hour period. Competitive and moderate tennis scored near the top of the list. Why? The on-going high level of anaerobic activity in tennis compares quite favourably to all other sports. This makes tennis a wonderful first sport to build both stamina and strength in children.
