92% of Golfers Feel Physical/Performance Decline Due to Age - About 40% Have No Countermeasures, Survey of 515 People

Bodysprout Co., Ltd. (Headquarters: Kawasaki City, Kanagawa Prefecture, Representative: Atsushi Kobayashi) conducted a "Survey on Physical Concerns and Performance in Golf" targeting 515 amateur golfers. The results revealed that over 90% of players feel changes in their performance but lack effective countermeasures. Golf, enjoyed by approximately 5.6 million people in Japan, is widely popular as a "lifelong sport," but adapting to age-related physical changes is becoming a major barrier to continued participation.

Survey Summary

■ Survey Summary

- 92% feel changes in their body and performance.
- About half are concerned about their lower back.
- 89.6% recognize that "legs and lower back affect performance."
- 70% experience score fluctuations in the latter half of the round.
- 37.1% are "taking no specific measures."

Respondent Age Distribution

■ ① 92% are "playing while feeling physical changes."

To the question "Do you feel changes in your body and performance due to age?", 92% responded "I feel clear changes" or "I feel some changes." This means more than 9 out of 10 people stand on the course with some form of anxiety.

◼️ ② The biggest area of concern is the "lower back" — a risk for 1 in 2 people.

The most frequently cited area of physical concern was the "lower back," accounting for 46% of respondents.

Golf involves a series of rotational movements centered around the lumbar spine and pelvis from address to finish. Furthermore, the bent-over posture during address is one that easily concentrates the load on the lower back. In Japan, where "lower back pain is a national ailment," golf has become a sport that unknowingly confronts this challenge.

■ ③ "Concerns about legs and lower back affect scores" — 89.6% recognize this.

89.6% of golfers answered that "concerns about legs and lower back affect performance." This means about 9 out of 10 are playing with anxiety.

Decreased distance, swing instability, loss of reproducibility — underlying these issues may be pelvic instability during the address. Even if one tries to correct their swing, improvement is difficult if the foundation is not in place. Many golfers find themselves in a situation where they "know it, but can't change it."

■ ④ Scores consistently falter in the "latter half" — 70% concentrate their struggles in the final stages of the round.

Regarding when scores become erratic, approximately 70% cited the latter half of the round, with 10-13 holes (30.7%) and 14-18 holes (37.1%). This is thought to be not just due to simple fatigue, but rather the "accumulation" of postural misalignments throughout the round, which manifest significantly in the latter half.

■ ⑤ 37% are "unprepared" — the reality of having no viable countermeasures.

While "stretching" (46.2%) and "wearing supporters" (23.5%) were ranked high as current countermeasures, 37.1% responded that they "are not taking any specific measures."

Furthermore, regarding supporters, there are many complaints such as "restrictive movement" (41.3%) and "stuffiness" (21.5%), indicating that the reality is that "countermeasures = sacrificing playing comfort" hinders continuous care.

■ Anxiety about Continuing Golf

It was also revealed that 89.5% feel "the opportunities to play golf may decrease in the future" due to leg and lower back issues.

As the population ages, golf is gaining attention as a sport that can extend healthy lifespans. However, this survey indicates a significant gap between the desire to "continue playing" and the physical anxiety of "whether one can continue."

■ Consideration — The era of "body structure" first, before "technique."

This survey highlighted the reality that "the body's foundation is not in place" before one can "hit well."

Even if you try to correct your swing, if your pelvis is unstable, no form can be reproduced. Wearing supporters restricts movement, and the countermeasures themselves become an impediment to play. Score deterioration in the latter half is often dismissed as fatigue, but underlying it may be "accumulated misalignments" in the address posture.

This challenge is particularly pronounced among senior golfers.

The problem lies not in technique, but in the body's "structure." And until now, there have been no options to address this challenge head-on.

■ New Approach to Problem Solving — Golf-Specific Innerwear "BX GOLF"

Stretching may be effective but difficult to continue, and supporters restrict movement.
As a result, the reality is that about 40% of golfers go out on the course "doing nothing."

"BX GOLF" was developed to fill this void.

The approach of BX GOLF is simple.
Just by wearing it, it stabilizes your address posture and leads to score improvement.

With a design specialized in correcting the "address posture" before the swing:

Structure that stabilizes the pelvis in a natural position → Creates a foundation for the swing.
Comfortable to wear without restricting movement → Resolves the "restrictive movement" issue of supporters.
Material design that also ensures breathability → Eliminates the stress of "stuffiness."

It solves the "dissatisfaction with existing countermeasures" revealed by the survey through each design element.

◼️ Comment from Atsushi Kobayashi (Developer of BX GOLF), Posture Specialist

"Golf is said to be a sport that can be enjoyed throughout one's life. However, in reality, many people continue to play on the course while suffering from leg and lower back issues.

The results of this survey are completely consistent with what I have observed in practice.

Aging is unavoidable. However, it is not true that nothing can be done about physical changes. If the pelvis is stable, posture will improve, and the burden on the body will decrease. An option to "continue playing the golf I love for a little longer" should emerge."

BX GOLF is the embodiment of this conviction. It proposes a new standard in the golf world: supporting a life where one can continue playing golf without anxiety by correcting the body's "foundation."

■ Product Overview

This is a "wearable golf gear" innerwear jointly developed by posture specialist Atsushi Kobayashi and PGA Teaching Pro Hideki Minami. Its patented structure (V-shaped power net) that straightens the pelvis reduces lower back strain, maintains an ideal address posture, and supports swing stability and score improvement.
